Key Points

‧ Erection supplements are a multi-billion dollar a year endeavor.

‧ The supplement list below can go a long way towards helping your male enhancement goals.

‧ Certain supplements- like L-Arginine can be an alternative to erector drugs like Cialis.

It doesn’t matter what you call it—getting a boner, a hard-on, or wood—internet searches for stronger erections won’t stop. That’s especially true for people who are living with erectile dysfunction. It’s no surprise that the market for erectile dysfunction treatments is expected to reach 4.7 billion dollars in revenue by 2026.

There’s a big market for erection-boosting medications including Cialis and Viagra, especially given how easily you can access them via a prescription from your doctor and via telehealth companies like Hims and Roman that have them delivered to your door. But what about other options, like those over-the-counter supplements for a better sex life you see advertised on television or through random Instagram ads? Are those safe supplements for better sex and stronger erections?

Of the many supplements out there that claim to boost your erection and give you a better hard-on, many are dubious. There are significant dangers when it comes to “herbal Viagra,” explains Jamin Brahmbhatt, MD, a urologist and sexual wellness expert at Orlando Health. This term is used to describe the natural supplements advertised to boost your erection.

If you go to a convenience store and see something behind the counter with a name like “Boner Blaster 5,000,” it’s a surefire way to know a supplement is not legit. “Even if you buy them at a big retailer, and they seem to be made of ‘natural’ ingredients, be cautious,” he says. “No one is regulating this stuff.” That’s concerning. It’s not clear what you could be putting in your body and there’s always the chance it could harm your overall health—including your sexual health.

Is it all bad, though? Are any of these over-the-counter erection supplements safe and effective for your sex life? Surprisingly, yes, there are a few. Here is what to know about a few expert-approved sex supplements that are good for your health and your erectile health.

Omega-3s

Omega-3 fatty acids are a maybe when it comes to protecting your heart and your erections. The research goes back and forth about whether fish oil supplements are really helpful for the heart. If the scales tip toward them being helpful to your heart, then your erections may benefit as well, explains Brahmbhatt. That’s because heart-healthy changes are geared toward improving blood flow and increasing the size of blood vessels, he says.

Your penis has the smallest blood vessels in your body, meaning they’re easier to get clogged up. And impeded blood flow is bad for erections, so anything that improves blood flow is good.

At first, it might not make sense that many blood pressure medications list erectile dysfunction as a side effect, he adds. That’s because they modulate the way that blood vessels open and close, which can reduce flow overall, especially down south.

By contrast, omega-3 fatty acids can have the opposite effect because they lower inflammation that might be affecting blood vessels, while also reducing blood clotting. That can help boost your blood flow. While you can get your omegas from supplements, getting them from foods such as fatty fish is your best bet.

L-Arginine

L-arginine is an essential amino acid that can be good for both heart health and erectile issues, Brahmbhatt says.

In fact, a study in the journal Andrology found that patients with severe or complete erectile dysfunction had L-arginine levels that were significantly lower than that of men with milder forms of ED. L-arginine might help trigger the production of nitric oxide, a compound important in getting and maintaining erections.

In addition, “L-Arginine is a peripheral vasodilator via a pathway similar to PDE5 inhibitors [those include Cialis and Viagra]. Vasodilation is associated with increased blood flow and thus possibly better erections,” says Peter Tsambarli, MD, assistant professor of urology at RUSH University Medical Center in Chicago.

L-arginine is found in most protein-rich foods such as red meat, poultry, beans, and dairy products, according to according to the Mayo Clinic, which has marked it as generally safe but cautions people who take blood pressure meds to talk to a doctor first.

This is good advice for any supplements if you’re on blood pressure medications, Brahmbhatt says. That’s because a product like L-arginine can reduce your blood pressure—which is great if it’s a bit too high, but not if you’re already bringing it down with meds. In that case, you may see a sudden and dramatic drop in pressure that could cause you to faint, or in extreme cases, have a stroke.

If you’re not on those meds and want to try the amino acid, Brahmbhatt suggests starting at a dose of about six grams a day to see how you tolerate it. In some people, the supplement can cause side effects including nausea, abdominal pain, diarrhea, and bloating.

L-Citrulline

In addition to L-Arginine, L-Citrulline may help with stronger erections. This is because L-Citrulline is converted in the body to L-Arginine, explains Tsambarli. L-Citrulline can also aid in the production of nitric oxide. “Nitric oxide is involved in vasodilation (widening and opening up of blood vessels) which can begin and maintain the erectile response,” says Michael Eisenberg, MD, professor of urology at Stanford Health.

A 2001 study published in Expert Opinion Pharmacotherapy states that “NO is the principal agent responsible for relaxation of penile smooth muscle.” (FYI, penile erection is a vascular phenomenon that directly results from smooth muscle relaxation along with arterial dilation and venous restriction.)

Vitamin D

Some studies suggest that men with vitamin D deficiencies are more likely to have erectile dysfunction, says Brahmbhatt. That may be because low levels of the vitamin are associated with diseases like hypertension, coronary artery disease, and peripheral vascular disease. Basically, blood flow issues that affect your system can also raise your risk of ED.

Although you can get some vitamin D from foods including salmon and eggs, along with sunshine, most people in the U.S. are lacking the vitamin, especially if you live in the northern part of the country, says Brianna Elliott, R.D., a coach at nutrition counseling service EvolutionEat.

She adds that the longer you maintain low levels, the more effects you might see, including potential ED. But how much you should take is a moving target. The National Institutes of Health recommends 600 IU, while the Endocrine Society suggests much higher levels of up to 2,000 IU daily.

“This would be a good topic for your next doctor visit,” Elliott says, noting that it’s easy to test for vitamin D levels, and from there, you can get a recommendation about dosage amounts based on that information.

Folic Acid (B9)

Another supplement that is good for overall health and wellness, including erectile health, is folic acid or B9. Some research has linked improvement in sexual performance with folic acid supplementation, which lowered levels of the amino acid homocysteine, explains Tsambarli. “Homocysteine levels were previously found to be higher in men with ED than their counterparts who were not suffering from ED.”

The bottom line on sexual supplements?

Despite the fact that there are some supplements that may help with erections to a certain extent, supplements are not held to the standards of pharmaceuticals. Always choose supplements with a third-party verification, like NSF or USP. “I always attempt to temper expectations when utilizing supplements for sexual performance,” says Tsambarli.

In general, here’s the best possible “supplement” you can take for your sex life: lifestyle changes. A healthy diet, regular exercise, good sleep habits, and lower stress levels all go a long way toward improving your health, as you’ve heard a million times.

“Overall health and sexual health are closely related,” explains Dr. Eisenberg. “Thus, anything that benefits heart health can also benefit sexual health. A good diet, exercise, and maintaining a good body weight can all help [as well].”

“Diet and exercise have consistently outperformed supplements and have a significant and reliable impact on sexual performance,” says Tsambarli.

“It’s definitely easier to stop at the gas station and get some shady supplement that makes promises about boosting your libido or increasing your girth,” Brahmbhatt says. “But play it safe, skip that junk, and do what’s proven to help your sex life: healthy lifestyle habits.”

 

 

 

Biohacking and Optimising Your Health During Covid-19

How to Optimise Your Health During Covid-19 With Biohacking

By Dr Jonathan Seah | 14 Mar 2022

This article is a repost which originally appeared on PRESTIGE

Edited for content. The opinions expressed in this article may not reflect the opinions of this site’s editors, staff or members.

Our Takeaways:

· Dietary biohacks can be used for more efficient recovery from illnesses like Covid-19.

· It is possible to potimize the health beyond functional levels with diet and supplementation.

· Plant based and ketogenic diets are considered optimal for dealing with Covid-19.

For most of the past two years since the start of the COVID-19 pandemic, we’d been relatively fortunate in Hong Kong compared to many other cities in the world, without full lockdowns, mass testings, and most importantly, significant numbers of severely sick and dying people.

Unfortunately, this has all changed these past two months, with almost 500,000 cases and 2,000 deaths[1]. While most of these have been amongst the unvaccinated, elderly or chronically ill, some younger people and even children have been affected. Even though most of my friends are already vaccinated, they wanted to know if there was anything else they could do to improve their chances if infected. So after a chat with some LifeClinic doctors, I’ve summarized some suggested biohacks below – all of which are backed by peer-reviewed scientific research (links to the research papers are at the end).

Before I begin, it might be useful to understand how my medical philosophy differs from that of regular doctors. Most “conventional” doctors were taught, like I was over 30 years ago, that there are essentially only two states of health – either you are sick, or you are not sick. “Functional” medicine doctors, however, who are conventional doctors with extra related training, believe that it is possible to achieve an even better, “optimal” level of health – essentially a super-powered state that will allow you to function better than the average person at both work and play (potentially more energy, better memory, better sex, look younger), and to possibly live longer.

While media attention has focused on Hollywood and Hong Kong movie stars and Silicon Valley billionaires who see functional medicine doctors reverse both their internal and external ageing with advanced treatments like intravenous NAD+, peptides, exosomes, or cytokines, I personally believe that much of the benefits of functional medicine – especially with regards to improving your body’s immune functions to potentially reduce the severity of a COVID-19 infection – can be achieved with relatively inexpensive micronutrients you can purchase yourself[2].

What causes severe Covid-19 disease and death

As we have now seen over the past 2 years, about 80 percent of people who get COVID-19 have no symptoms or only mild symptoms, 14 percent get severe symptoms like pneumonia, and 5 percent get critical symptoms like respiratory distress or multi-organ failure, and about 2 percent die[3]. The mechanism for these bad outcomes is still being investigated, but much of the research points to abnormal immune responses (culminating in what has come to be called a “cytokine storm”) and the presence of chronic inflammation. We believe this is probably why the outcomes are often worse for older people[4], (who typically have aged immune systems), and for those with some pre-existing illnesses that cause systemic inflammation (like diabetes, high blood pressure, and cardiovascular disease)[5].

So, the question then becomes – what are some simple things we do ourselves to reduce the chronic inflammation in our bodies, and to rejuvenate our immune systems?

The best Covid-19 diets: Plant-based and clean keto

An unhealthy diet could increase your risk factors for a severe COVID-19 infection[6]. Over the past year, there have been a few very large research studies that have demonstrated quite clearly that what you eat can affect how your body reacts to COVID-19.

One of the most important was a study conducted amongst almost 3,000 front-line health care workers (doctors and nurses) across 6 countries, which showed that those who followed a largely plant-based diet (mostly vegetables and plant proteins, and less red and processed meats and sweetened beverages and alcohol), had a 73 percent lower likelihood of developing moderate-to-severe COVID-19 infections[7]! This is possibly because a plant-based diet often has more micronutrients that are essential for the proper functioning of the body’s immune system, such as polyphenols, carotenoids, dietary fibre, vitamins A, C, E, and folate, and minerals like iron, potassium, and magnesium. Or because the virus itself is weakened in a nutrient-dense environment[8]! Also, in this same study, those who ate a plant-based diet together with fish had a 59 percent lower chance of moderate-to-severe COVID-19 infection. In this case, it is thought that the mechanism of action might be a reduction of chronic systemic inflammation. Fish is an important source of vitamin D and omega-3 fatty acids, which have anti-inflammatory effects on the body. (Diazepam online)

An even larger study, this time of almost 600,000 people, also showed that those who ate diets characterized by more healthy plant-based foods correlated with a 41 percent lower chance of severe COVID-19 infections[9].

Separately, there has also been a lot of interest in investigating if ketogenic diets could be beneficial in COVID-19 patients. One study conducted in Italy on 102 hospitalized patients showed that those fed with a low-calorie ketogenic diet had a lower admission to the ICU and a lower death rate than those fed on a low-calorie standard (Mediterranean) diet[10]. This could be because a ketogenic diet can better regulate glucose metabolism and reduce systemic inflammation, as the SARS-CoV-2 virus seems to grow more quickly in a high glucose environment[11] and maybe why many diabetics have a severe COVID-19 infection. Additionally, the ketone bodies generated when a body is in ketosis appear to not only serve as fuel but also to promote resistance to oxidative and inflammatory stress[12] which can contribute to severe symptoms. Lastly, over time, ketogenic diets can reduce obesity and hypertension, which could also help improve COVID-19 outcomes.

So what are the key takeaways from this section? To increase your chances of a good outcome in case of infection, try to have a mostly plant-based diet or a “clean” ketogenic diet – that is to say, one that uses mostly plant fats, and fewer animal fats which of course can themselves be very inflammatory.

Biohacking: Your micronutrient heroes

Dietary insufficiency of vitamins and minerals has been observed in high-risk COVID-19 patients, which may account for the increased risk of severe infections. It is also noted that much of the evidence surrounding supportive micronutrient use in COVID-19 utilize doses too high to come just from diet. This is why, given the simplicity, relatively low cost and low risk, supplementation during this period might make sense for many people. The doctors at LifeClinic usually make customized supplement recommendations based on the results of some specialized blood tests and track your micronutrient levels over time. This is because everyone’s biology and needs are different. However, since not everybody will have the opportunity to have this done, I am sharing with you what many functional doctors recommend, and what I take myself! By the way – several of these supplements can also increase sex drive and the ability to achieve orgasm, so think of this as an additional benefit if you are in quarantine with your significant other[13][14].

Vitamin D

Vitamin D is a fat-soluble vitamin, that is both ingested via foods, as well as made by our bodies in the presence of sunlight – another reason my family loves to go hiking! Vitamin D insufficiency could affect almost 50% of the population worldwide[15]. Essential for a healthy lining in our throats to protect against the initial viral entry into our bodies[16], vitamin D is also critical for a healthy immune system. The primary effects of vitamin D in COVID-19 infections are to reduce the viability of the virus and the excessive inflammatory response[17]. In a study conducted on 212 COVID-19 cases, the probability of having a mild disease was correlated to high levels of vitamin D, and, as the vitamin D levels decreased, the risk of severe disease increased. In fact, in COVID-19 hospitalizations with vitamin D deficiencies, treatment with vitamin D shortened the hospital stays and decreased the death rate by more than twice[18]! Yulia and I take 5,000 IU of D3, and we give our son a few drops of D3 liquid every day. You might need more if your levels are low[19].

Vitamin C

Vitamin C is a water-soluble vitamin that cannot be made by humans, which means that it is not well stored in our bodies and must be taken regularly through food or supplements. In addition to being necessary for the body’s outer protective layers (skin and mucosa) and being a powerful antioxidant, it also has critical roles in immunity, including proper white cell movement and antibody production. While most conventional family doctors believe that just 90-120 mg daily[20] of vitamin C is sufficient, I would recommend higher doses to potentially help improve infection recovery times[21], as has been seen with the common cold and even pneumonia[22]. There is even documentation of more than 10,000 mg a day of vitamin C given intravenously (IV) as part of a successful COVID-19 hospital treatment programme[23]. Given that, at home, we can only use oral Vitamin C, Yulia and I take about 1,000 to 2,000 mg a day, and we give our son about 200 mg.

Zinc

Zinc is a key trace mineral that has many potential health benefits against COVID-19 infections, via improving the immune response, minimizing the inflammation, preventing lung injury, and inhibiting viral growth through the interference of the viral genome transcription, protein translation, and attachment[24][25]. It has been shown that zinc supplementation can increase the number of T cells and NK (natural killer) cells in your body – important parts of the immune system, and conversely zinc deficiency can lower the number of white blood cells that fight infections[26]. Several studies are currently ongoing to further investigate the effects of zinc on COVID-19 symptoms and outcomes[27]. We take between 30-50mg of zinc a day.

Quercetin

Quercetin is a natural substance known as a polyphenol. Its main natural sources in food are vegetables like onions and broccoli; fruits like apples, berry crops, and grapes; and some herbs; tea; and wine. It is an antioxidant and anti-inflammatory, can affect human immune functions, and also has antiviral properties. In a recent randomized study with 152 COVID-19 patients, it was found that in those who received quercetin 500 mg twice a day as supportive therapy, there were statistically significant improvements in all the clinical outcomes measured (the length of hospitalization, the need for oxygen therapy, progression to intensive care units, and death). The results also confirmed the very high safety profile of quercetin and its possible anti-fatigue and pro-appetite properties[28]. Yulia and I are currently following this protocol – 500 mg twice a day.

Omega-3 Fish Oil

Omega-3 fish oils are polyunsaturated fatty acids and include both eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids, and are known to have immunity and anti-inflammatory, and antiviral properties, and may even improve oxygenation in COVID-19 patients[29]. In a double-blind, randomized clinical trial conducted on 128 critically ill COVID-19 patients, omega-3 supplementation improved the levels of several parameters of respiratory and renal function[30]. However, on the negative side, there is also a possibility that they can make cell membranes more susceptible to non-enzymatic oxidation, so it is best to not overdo it. Yulia and I take 1,000 mg a day.

Probiotics

Maintaining good gut health is critical for a strong immune system. Our gastrointestinal system has trillions of microorganisms that live in harmony with us (this is known as your “gut biome”). They not only protect against harmful pathogens like the virus causing COVID-19 but also are a major “training ground” for our immune system. With modern living characterized by too much stress, refined carbohydrates, pollutants, medications and antibiotics, this protective lining can be severely weakened. Probiotics strengthen this barrier and can activate various protective immune factors such as IgA antibodies, cytotoxic T-cells and antimicrobial proteins. Recently a research study done right here in Hong Kong showed that there was a distinct correlation between the amount of certain healthy gut bacteria and the level of COVID-19 antibodies that developed after vaccinations[31]. I would recommend including a decent probiotic in your supplementation regime.

Of course, if you suspect your micronutrient levels are very low and you want a quick boost to your immunity, it might not be a bad time to get a consult with a functional medicine doctor or practitioner to evaluate if you might benefit from IV micronutrient therapy. However, if you’ve already been vaccinated and don’t have any major chronic illnesses, the above diet and supplements, in combination with some physical activity, would probably be enough to sufficiently improve your and your family’s chances of having just mild or no symptoms if you were to get COVID-19 infection – which for most of us will inevitably happen at some point! There are a few other micronutrients that you could consider adding, for example, selenium, magnesium and liposomal glutathione, but they’re not as easy to obtain locally. In any case, the very fact that you’ve actually read through this article means that you’re probably already doing all the right things. The very best wishes from our family to yours during this challenging time in Hong Kong!

Nutrigenomics Might Be the Future of How You Eat

Our Takeaways:

· Nutrigenomics is a field where a combination of disciplines merge to potentially optimize nutrition for individuals

· In addition to dietary optimization, nutrigenomics may also lead to more knowledge on finding and preventing health problems.

· Care should be taken when employing nutrigenomics as this branch of science is in its early stages.

If there’s one thing the last several decades of nutrition research have proven, it’s that there’s no one-size-fits-all diet. While many factors are at play, one reason certain eating plans work for one person but not another may have to do with our genetics.

Nutrigenomics is a fascinating, up-and-coming field that uses genetic testing to determine the interplay between genes, nutrition, and health. This information is used to help pinpoint the ideal diet for each individual.

Here’s a look at what nutrigenomics is, what you can expect if you try it, and how it might shape the future of personalized nutrition.

What is nutrigenomics? 

“Nutrigenomics is the study of the relationship between genomics, nutrition, and health,” says geneticist Jan Lim, MS, of CRI Genetics. “The field includes both the study of how the whole body responds to micro- and macronutrients, as well as the relationship between single genes and single gene/food compound interactions.”

You may sometimes hear this field referred to as “nutrigenetics.”

Technically, nutrigenomics refers to how nutrients influence your body to express genes, while nutrigenetics refers to how your body responds to nutrients because of your existing genetic makeup. However, many people use the terms interchangeably.

History of nutrigenomics

Though the science of nutrition genetics is still in its infancy, the idea that our genes can determine our best diet isn’t as space-age as it might seem.

In fact, as far back as the early 20th century, British physician Archibald Garrod is credited with establishing a connection between nutrition, genetics, and phenotype.

The Human Genome Project of the 1990s, which mapped out human DNA, paved the way for the modern era of nutrigenomics. Since then, hundreds of studies have examined genes’ influence on the body’s response to diet, as well as the other way around.

Today, it’s not uncommon for practitioners like dietitians and doctors to use genetic testing to assess patients’ dietary needs and set customized health goals.

Benefits

Genetic testing as part of nutrition counseling might sound rather extreme. A genetic workup just to see if you should eat low carb or get more vitamin C?

However, as part of an integrative nutrition approach, nutrigenomics can shed light on issues a simple health history can’t. This includes everything from a predisposition to heart disease to why you’re not losing weight when you’ve tried everything.

“Genomic testing truly is useful for anyone wanting to be proactive about their health,” says dietitian and certified genomic medical clinician Andrea Chernus, MS, RD, CGMC. “Genomic testing can help to explain why situations exist for a patient, such as which style of eating might suit them best.”

By looking at your genetic makeup, a practitioner may be able to advise you on certain eating patterns that will or won’t work well for you. For example, gene variants might mean your body wouldn’t benefit from a vegan diet or wouldn’t adapt well to a keto diet due to genomic tendencies for fat metabolism.

A nutrigenomic test can even uncover your personal best sources of both macro- and micronutrients.

Perhaps your body is unable to optimally use omega-3 fatty acids from plant sources, or you have trouble converting sunshine into vitamin D. With this data, a trained practitioner can instruct you on which foods to eat or supplements to take to meet your needs.

Likewise, predispositions toward certain diseases may show up on a nutrigenomics test.

“We may be able to see gene variants that increase one’s risk for breast cancer due to the genes involved in estrogen metabolism, for example,” Chernus notes. Heart disease, diabetes, obesity, and mental health have all been linked to genetic expressions, and all have dietary prevention strategies.

Empowered with this information, you can make preventative choices to mitigate risk through diet.

What to expect

Interested in pursuing a genetic approach to nutrition, but not sure what to expect? Nutrition counseling using nutrigenomics is surprisingly painless.

“The experience should start with a detailed health questionnaire so the practitioner has a complete understanding of the patient’s health status, history, family history, and current and past lifestyles,” says Chernus. “The actual test involves an at-home cheek swab. It’s typical for a test to evaluate anywhere from 80 to 150 or more genes. It’s quite simple to do.”

In some cases, if your results raise additional questions, a blood test may follow.

Once your test results are back, your dietitian or other health professional will evaluate them and work with you to develop an action plan for eating.

Potential drawbacks of nutrigenomics

Although extensive research has been conducted on the connection between genetics, diet, and health, the science of nutrigenomics is still emerging. “Nutrigenomics is a relatively new field of research, so we still have a lot to learn,” says Lim.

This isn’t to say that genetics aren’t a helpful piece of the puzzle when it comes to nutrition counseling. Just recognize that nutrigenomics won’t solve every diet conundrum, and that genes are just one of many factors that influence health and ideal dietary choices.

“Genomic testing should not be the sole criteria used to make recommendations,” says Chernus. “We need to include lifestyle, health history, health status, personal preferences, cultural identity, willingness of the patient to change, and their own health goals in our work.”

The availability of direct-to-consumer genetic testing for diet purposes, while it may seem exciting and convenient, is another potential drawback.

“The main drawback [of these tests] is that they’re not interpreted by a skilled clinician,” Chernus says. “Skilled practitioners use a polygenic approach: how all of the genes are part of bigger systems in the body. They interpret how these systems work together in the totality of one’s health.”

To understand the relationship between your own genome and diet, it’s always best to consult with a health professional who specializes in nutrition genetics.

Takeaway

“Every body is different” isn’t just true of our shape or physical type. It’s true down to the genetic level. Although nutrigenomics is a relatively new field that’s still gaining mainstream acceptance, many nutrition experts believe it’s the future of dietary counseling.

As part of a comprehensive nutrition philosophy that looks at the whole person, nutrigenomics could help people overcome health obstacles other approaches can’t.

“The more personalized our approach, the better the outcome,” says Chernus.

7 Muscle-Building Supplements That Actually Work

If you want to get stronger, these will help.
By Chris Mohr, Ph.D., R.D. Jan 25, 2022

This article is a repost which originally appeared on MEN’S HEALTH

Edited for content

Our Takeaways:

· Supplements have come a long way in the past few decades

· Statistically, the average amount of lean mass a typical man can gain is 1 to 2.5 pounds per month

· There are many different sources for protein supplements which can fit into most people’s requirements

I remember it like it was yesterday—waking up Christmas morning and unwrapping a Hulkamania Workout Set. Blue five-pound dumbbells, a poster, jump rope, grip-strength handle, headband, and wristbands. Like many other kids my age, I followed along with those workouts religiously, in addition to saying my prayers and eating my vitamins, just like Hogan preached. But I never quite grew the 24” pythons Hogan promised. (Maybe I didn’t quite say the right prayers or have the right vitamins?)

Fast forward many years. Vitamins—and their umbrella category “supplements”—have certainly changed. Tons of scientific research has emerged since those Hulkamania days. And I’m a registered dietitian now, so I’m well aware of all that research and the supplements on the market that actually work because they’re backed up by some of that research.

But, let’s first discuss what it takes to build muscle and how much you can expect supplements to help with that growth.

First, building muscle isn’t easy, doesn’t happen overnight, and actually happens more with proper rest and recovery.

Second, “According to a 2017 meta-analysis and general anecdotal evidence working with athletes, the average amount of lean mass a typical man can gain is 1 to 2.5 pounds per month” says Marie Spano, M.S., R.D.N., C.S.C.S., C.S.S.D., author of Nutrition for Sport, Exercise, and Health and MLB Consultant. “Novices and those who are underfed at the start of training can increase their intake of calories and protein may be on the higher end of this scale.”

This said, let’s look at the supplements that have potential to improve your gains, assuming all other factors like overall nutrition, sleep, recovery, training programming, and the like are well controlled.

And all my picks are either Informed Choice, NSF Certified or USP Certified, assuring the quality of the ingredients within the products and that they’re free from any contaminants.

1 Whey Protein Isolate, Unflavored

Exercise breaks down muscle. Protein is needed for repair and recovery. Whey protein is absorbed quickly, is high in leucine, an amino acid that’s necessary for growth, is accessible, affordable and is most rapidly absorbed.

2 Micellar Casein, Unflavored

Dairy protein is made up of two types: whey and casein. Whey is more quickly absorbed, while casein is more slowly absorbed. But both have merit in terms of recovery and potentially muscle growth.

A 2020 study published the journal Physical Activity and Nutrition examined the data around pre-sleep casein protein effects on post-exercise recovery and concluded that studies have shown that pre-sleep casein protein (40 to 48 grams, 30 minutes before bed) could help post-exercise recovery and positive affect acute protein metabolism and performance.

3 Almond Protein Powder

Sometimes you just don’t want a dairy-based protein. Enter, almond protein.

So this one isn’t actually a supplement, but rather a food made from a single ingredient, blanched almonds. Each serving packs 20g of plant-powered protein, with the bonus of being rich in calcium and fiber to help fuel your hard-working muscles. Bonus, it’s versatile and isn’t just good for smoothies, but I just used some in banana bread, it works well with oats and, yes, smoothies too.

4 Beta Alanine-SR

While not usually thought of for its contributions to muscle, some data certainly supports Beta Alanine as a muscle-building supplement.

One 2018 study published in the Journal of International Society of Sports Nutrition provided subjects with 6.4 grams/day of beta-alanine (divided as 8 X 800 mg doses, 1.5 hours apart). After a specific exercise protocol, the researchers found that supplementation was effective at increase power output.

More power output can ultimately lead to more gains.Notice the divided doses; one side effect of beta-alanine supplementation can be tingling in the extremities, but dividing doses can minimize that side effect.

5 Creatine

Many supplements often come in with hurricane force winds, full of promise and gusto. And they go out just as quickly as the results rarely match the marketing hype. Creatine is an exception.

With over 25 years of research support, creatine helps regenerate ATP (the “energy currency” of the body) helping with recovery, size and strength. Eric Rawson, Ph.D., Professor at Messiah College, is a creatine OG, researching the supplement in the early 2000’s as a doctoral student at UMASS when I was working my M.S.

He adds “Once muscle creatine is increased, the performance of brief, high-intensity exercise can be improved. As an example, a soccer player on a breakaway would have more fuel in their muscles to sprint past the defense. Also, resistance training is a form of brief, intense exercise, so performance is improved in the weight room as well. In this way, creatine monohydrate supplements are a dual threat; improved sport performance and also enhanced strength and conditioning workouts leading to better training adaptations and has been shown to be effective in all populations, regardless of age or gender.”

6 Ultimate Omega-D3 Sport

This one may come as a surprise. Omega-3 fats are widely researched and noted for their heart and brain health benefits. But a 2017 research study also found fish oil supplementation may alleviate delayed onset muscle soreness after resistance training. While this study used a relatively high dose (6 grams daily), others have found similar benefits with lower, 3 gram doses.

7 Vitamin D3 2000 IU (50 mcg) Softgels

Like fish oil, vitamin D may come as a surprise. Not many jacked up bros flexing with their bottle of vitamin D. But insufficiency is common, particularly in the winter months for those north of Atlanta where the sun isn’t quite as strong or you won’t be outside with exposed skin as often.

Vitamin D concentrations play a role in so many of the bodies systems, including skeletal muscle strength and function. This known connection led to the idea that increased serum vitamin D concentrations could be a complementary approach to enhance strength following exercise.

Subjects in a 2013 study were randomly assigned to 4,000 IU’s vitamin D and the researchers found this supplemental dose attenuated blood markers as a result of muscle damage and enhanced recovery overall. Most experts agree optimal serum levels should be between 40-80 ng/mL, so ask to have your levels tested the next time you have bloodwork taken.

Is fish oil beneficial for men?

What to know about the benefits of fish oil for men

Medically reviewed by Grant Tinsley, PhD — Written by Zia Sherrell, MPH on March 7, 2021

This article is a repost which originally appeared on MEDICALNEWSTODAY

Edited for content

Fish oil is a common dietary supplement rich in omega-3 fatty acids. Research suggests they could be beneficial for health and protection from certain diseases. Additionally, there may also be specific benefits for men, as fish oil might help with erections and fertility.

People who eat lots of oily fish may get enough of these fatty acids from their diet. For those who do not, or only occasionally, eat fish, taking a fish oil supplement could ensure they get sufficient amounts.

This article explores the potential benefits of fish oil for men and the possible risks. It also suggests how people may increase their levels of omega-3.

Definition of fish oils

Fish oil comes from various species of oily fish, such as mackerel, tuna, and herring. Manufacturers can use many different methods to harvest fish oil, but most techniques typically involve a four-stage process that includes cooking, pressing, filtering, and centrifuging the resultant oil.

Fish oils contain omega-3 polyunsaturated fatty acids. These are essential fatty acids that the body cannot make itself. Two of the most well-known types of omega-3 are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Consuming fish oils and omega-3 may bring some health benefits and help with a number of health conditions.

List of possible benefits

Fish oil may have an impact on different areas of health and be a useful supplement for many people. The following is a list of some potential benefits of fish oil for men.

Sexual health and fertility

Although not widely reported, fish oil supplements may have benefits for sexual health and fertility.

A 2017 animal study examined the effects of omega-3 fatty acids and erectile dysfunction due to atherosclerosis. In this condition, the blood vessels narrow, which can affect erections. Rats in the treatment group fed omega-3 fatty acids demonstrated significantly improved erection quality.

It is essential to bear in mind that animal studies do not indicate the same results in humans. However, an earlier review also indicates that omega-3 could help men with erectile function.

In a 2020 study of 1,694 young male participants, those who reported using fish oil supplements had larger testes and higher semen volume and quality.

They also had a healthier-looking profile of follicle-stimulating hormone and luteinizing hormone. These are two key hormones that regulate sperm production.

Although the study cannot conclude that the fish oil is causing the improvement, it suggests that it may play a role.

Mental health

Research suggests that individuals with depression may have lower blood levels of omega-3 fatty acids. In a small study of 23 people published in Psychiatry Research, supplementation with omega-3s helped improve symptoms of depression within 3 weeks.

There are links between depression and memory problems. Supplementing with DHA alone or in combination with EPA may improve memory function in some groups of adults.

While studies suggest that omega-3 supplementation may help prevent cognitive decline, especially in older adults, a 2019 review notes that more research is still necessary.

Heart health

Heart disease accounts for 1 in 4 deaths in the United States each year. According to the Centers for Disease Control and Prevention (CDC), heart disease is the leading cause of death for men in the U.S.

Eating fish may have a protective effect on heart health by reducing some of the risk factors for heart disease.

Triglycerides are a type of fat found in the blood, and although the body needs them, if levels are too high, they can increase the risk of heart disease.

Fish oil may help lower elevated triglyceride levels and blood pressure. Eating fish may also help to significantly lower low-density lipoprotein or “bad” cholesterol.

While many sources promote the potential benefits of fish oil for cardiovascular health, clinical studies do not consistently support them. For example, an analysis published in JAMA Cardiology could not find a clear link between fish oil and lower heart disease risk.

Eye health

Some evidence suggests that an adequate intake of fish oil may help protect eye health. A 2017 review notes that fish oil may play a role in the treatment of inflammatory eye diseases such as age-related macular degeneration (AMD) and dry eye disease.

A 2019 study indicates that people who regularly consume fresh fruits, vegetables, and fish were less likely to develop AMD compared with those who did not.

The American Academy of Ophthalmology (AAO) recommend fish oils to reduce the symptoms of dry eye. However, some evidence suggests they have no effect. A 2018 study found no evidence to indicate that taking fish oil supplements was more helpful than taking a placebo for dry eye.

Optometrists may recommend taking omega-3 supplements or increasing dietary fish consumption to benefit eye health, even though some scientific evidence suggests fish oils are not suitable for this purpose.

Risks and considerations

Before deciding to supplement their diets with fish oils, people should also consider the possible risks.

While some research indicates that eating a diet rich in omega-3 may help prevent prostate cancer, other research suggests otherwise. A 2013 study notes that a high fish oil intake may actually increase the risk of high-grade prostate cancer.

The National Institutes of Health (NIH) note that the link between omega-3 and different types of cancer, such as prostate, currently remains unclear.

Some people may experience mild side effects if they supplement with fish oil. These may include unpleasant taste, bad breath, diarrhea, flatulence, nausea, and other digestive symptoms.

How to increase your omega-3 level

The three primary omega-3 fatty acids are EPA, DHA, and alpha-linolenic acid (ALA). While the first two are present in fish oil, ALA comes from plant oils such as flaxseed, soybean, and canola oils.

ALA is an essential fatty acid, meaning that the body cannot make it, and it must come from a dietary source. Although the body can convert small amounts of ALA into EPA and then to DHA, the most practical way to increase these omega-3 fatty acids is from food or a nutritional supplement.

ALA is the only omega-3 that is essential, so it is the only one with a recommended adequate intake. Research suggests that males should aim for roughly 1.6 grams.

Both EPA and DHA do not have official recommended daily dosages as they are not essential nutrients. However, the British Dietetic Association suggest a daily dose of about 450 mg EPA and DHA for adults.

It can be difficult to judge the intake from nutritional supplements, as the amounts of fish oil may vary. For example, 1,000 mg of fish oil from one brand of supplement may contain less or more EPA and DHA than the same amount of oil from another brand.

People can get enough omega-3 by including the following foods in their diet:

  • fish and seafood, especially sardines, tuna, mackerel, salmon, and herring
  • nuts and seeds such as chia seeds and walnuts
  • plant oils such as flaxseed, soybean, and canola oil
  • fortified foods such as some types of eggs, yogurt, and soy beverages

Alternatively, people may benefit from a fish or vegetarian algae oil supplement to boost levels. Some evidence suggests that taking a fish oil supplement with a meal that contains fat may help to increase absorption.

Summary

Fish oil is rich in omega-3, which is an essential nutrient. Eating a diet containing oily fish, or taking a fish oil supplement, can ensure someone has an adequate amount.

Consuming more fish oil and omega-3 may offer some health benefits for men. This may include increasing fertility and improving heart health. However, men should weigh up the benefits with a potential increased risk of prostate cancer.

Anyone who is considering taking supplements should first check with a healthcare provider to ensure that it is safe.

Reducing The Risk Of Erectile Dysfunction With Nutrition

Reducing The Risk Of Erectile Dysfunction With Nutrition

Posted on Jun 01, 2020, 4 p.m.

At some point in their lives most men will struggle with penile health issues, when it comes to this these issues involve more than erections, ejaculations, and reproduction as poor penile health can be a sign of an underlying health condition.

Additionally issues that affect the penis can also impact other areas of your life including emotionally and socially. Bottom line is that routine maintenance in this area can also help to ensure optimum performance which includes managing stress, getting enough sleep, being physically active, and following a healthy well balanced diet. According to research from Harvard University men should masturbate (routine maintenance) 21 times a month to reduce the odds of prostate cancer by 33%.

Simply masturbating 21+ times a month is not enough to guarantee to avoid prostate cancer, but added to a healthy diet full of organic produce, getting enough sleep, managing stress, being active and exercising, this will go a long way. Ian Kerner, PhD,  recommends a plant based diet and incorporating plenty of fish rich in Omega-3 fatty acids, as well as “consuming red foods such as tomatoes that are rich in lycopene, as well as soy products that contain isoflavones, along with getting regular physicals that include a prostate exam, and plenty of exercise.”

Diet and nutrition play a bigger part in health than most people understand, and this includes penile health. Certain types of food have been shown to affect penis health, for example studies have shown that diets rich in flavonoids, which occur naturally in fruits, vegetables and whole grains, are associated with a reduced risk of erectile dysfunction in men under the age of 70.

There are many things that can affect an erection like poor health, smoking, and certain medications. Following a sub par diet, how much you eat, and how often you eat can affect your mood, energy levels, blood flow, and hormones which are all very important to your sex life.

It stands to reason that if certain foods can boost your erection, keep sperm healthy, and boost testosterone levels then eating habits exist that can also kill your libido. Unhealthy fats and added sugars can exacerbate erectile issues, and lower testosterone levels. Alcohol is a depressant which can numb the feeling of sexual stimulation, alter the blood flow in/out of the penis, and decrease testosterone levels sapping libido, energy, and moods.

Achieving and maintaining an erection requires good blood flow and plenty of nitric oxide. Flavonoids have been shown to improve cardiovascular health by helping to increase blood flow and the concentration of nitric oxide in the blood. Dark chocolate is rich in flavonoids, other choices include tea, citrus fruits, berries, apples, legumes, onions, tomatoes, broccoli, tea, grapes, celery, red peppers, ginger, red cabbage, asparagus, and leafy greens.

Pistachios are good for more than a snack, a study published in the International Journal of Impotence Research suggests that consuming these nuts for several weeks improved several parameters of ED including improved International Index of Erectile function scores, improved cholesterol levels and improved blood pressure with no notable side effects being observed.

Watermelon may help to improve sexual function as a study from Texas A&M University found connections between ED and watermelon, suggesting that citrulline found in watermelon helped to relax blood vessels and improved blood flow in a similar manner as to medications for ED.

Bananas are a great source of potassium which is great for keeping the heart and circulation strong. Potassium also keeps blood pressure in check by stabilizing sodium levels. Bananas are also a rich source of vitamin B which helps to increase energy levels, and combat stress that can lead to erectile dysfunction.

Salmon is a great source of omega-3 fatty acids which can help to enhance blood flow and enhance erectile function by helping to relax your arteries easing the way for blood to flow to the entire body without exception, including your penis. Salmon also contains vitamin D, selenium and magnesium which are all required to support testosterone levels and healthy sperm.

Anthocyanins are great for cardiovascular health, cherries are loaded with anthocyanins, which are flavonoids, that help to protect your artery walls and help prevent fatty plaques from forming in the arteries ensuring good blood flow and circulation.

Soluble fiber such as that in oatmeal has been shown to be great for satiety, fighting inflammation, to lower cholesterol levels and helps to keep your blood vessels smooth, healthy and stretchy, which also can apply to penis health.

Cruciferous vegetables such as broccoli can help to combat cancer, and the high vitamin C content helps to boost blood circulation and it has been linked to an improved libido. Cruciferous veggies such as bok choy, cabbage, and Brussels sprouts also contain glucobrassicins which help to clear the body of excess oestrogen which may help to boost your sex drive.

The antioxidant phytochemical resveratrol helps to open arteries by enhancing the production of nitric oxide, production of nitric oxide allows blood vessels to expand, and increases blood flow. Resveratrol works by expanding the tiny and main arteries in the penis much like medications for ED. It also helps to block enzymes that trigger the body to push away testosterone, which will help maintain high levels of the hormone and strong erections that should last well beyond foreplay.

After reaching the age of 30 testosterone levels begin to decrease, fortunately there are simple diet fixes that may help you, and because your brain, heart and penis are all intimately connected this is also good for your overall health and well being. Aging also affects your penis, as a result many men experience erectile difficulties, if you are one of them please consult with your physician as it can be an indication of an underlying condition that shouldn’t be ignored. Your physician can work with you to help determine the cause and work towards a solution, often lifestyle changes can help.

Fish oil can boost sperm count and make men’s testicles BIGGER, study claims

  • Scientists in Denmark tested the sperm and testicles of young, healthy men
  • Supplement-takers had bigger testicles and ejaculated more sperm, on average
  • Research only observed the link and could not prove supplements caused this
  • Experts say omega-3 could be a part of general good health, which is beneficial

Fish oil supplements could make men’s testicles bigger and boost their sperm count, a study claims.

Men who took the pills, which contain omega-3 fatty acids, were found to have testicles 1.5ml larger and to ejaculate 0.64ml more sperm, on average.

The men, who had an average age of 18, were included as regular supplement-takers if they had consumed fish oil for at least 60 out of the past 90 days.

Larger testicles and more sperm creation is linked to higher testosterone levels and better fertility, although the study did not test how fertile the men were.

The experiment was described by scientists as ‘well-conducted’ and ‘insightful’ but it was clear that it did not prove fish oil makes men more fertile.

Fish oil supplements contain omega-3 fatty acids, which are believed to reduce the risks of heart disease and improve brain health.

Researchers from the University of Southern Denmark did their study using 1,679 young Danish men going through military fitness testing.

In Denmark military service is mandatory for all healthy men over the age of 18, so the men in the study were not yet soldiers.

Each of the men were screened for STIs, had physical exams, gave sperm samples and then answered questions about their diets and lifestyles.

If someone was considered a regular fish oil supplement user, the research found, they produced millions more sperm in an average ejaculation.

The researchers wrote in their paper: ‘Fish oil supplements were associated … with higher semen volume and total sperm count, and larger testicular size.’

Ninety-eight men in the study said they took fish oil supplements regularly, while another 95 took vitamin D or C supplements.

Men in the fish oil group were less likely to have fertility problems, which were judged against the World Health Organization’s low sperm count limit of 39 million sperm per ml of semen.

The scientists found that 12.4 per cent of the men who took fish oil supplements (12 out of 98) had sperm counts below the WHO’s measure.

This compared to 17.2 per cent (192 out of 1,125) men who took no supplements.

And the longer someone had been taking supplements for, the more sperm they were likely to produce.

The researchers added that, based on a model fit and healthy 19-year-old: ‘Total sperm count was 147 million for men with no supplement intake, 159 million for men with other supplement intake, 168 million for men with fish oil supplement intake on fewer than 60 days, and 184 million for men with fish oil supplement intake on 60 or more days.’

The study did not give exact measurements for men’s testicle volume or sperm volumes – they only compared the two groups.

And the scientists could not explain why – if it was true – the fish oil improved sperm quality.

It was also not clear whether increased sperm volume was caused by – or caused – the change in testicle size.

Scientists not involved with the research said the study had been well-conducted but it didn’t say how much fish oil the men took.

And nor did it reveal the men’s diets, which may have shown they were getting omega-3 from other sources such as fresh fish.

Professor Sheena Lewis, reproductive medicine expert at Queen’s University, Belfast, said: ‘This is a large well-designed study and the association between fish oil intake and improved semen quality is compelling.

‘However, the study focuses on healthy young men; mostly with sperm counts already in the fertile range.

‘There is no evidence from this study that infertile men with low sperm counts benefit from fish oil.’

Dr Frankie Phillips, of the British Dietetic Association, said missing information about the men’s diets did make the study’s results less convincing.

She added: ‘Antioxidants, including vitamin C, selenium and vitamin A, as well as zinc and omega-3 fats all have a role in the production of healthy sperm.

‘There is much focus on the diets of women who are trying to conceive, ensuring that they are in the best possible position to achieve a healthy pregnancy, but diet might also be a factor involved in men’s reproductive health.

‘Omega-3 is present in a both animal and plant derived foods, but oily fish stands out as an excellent source of long chain omega-3, and the UK population currently consume way below the recommended ‘at least one portion of oily fish per week’.

‘So including omega-3 is already part of current dietary recommendations – this study on its own can’t prove that upping omega-3 will itself improve testicular function.’

The research was published in the journal JAMA Network Open, by the American Medical Association.

How to Boost Your Relationship and Sex Life with Healthy Eating

How to Boost Your Relationship and Sex Life with Healthy Eating

Food and sex

Much of the lore surrounding the desire- and performance-enhancing effects of certain foods is anecdotal. But a good diet can help boost your libido and ensure your body is working well. A poor diet can lead to a host of health issues, which may negatively effect your sex life. For example, erectile dysfunction is often linked to obesity and diabetes, which can be caused by a poor diet.

Food is an important part of your everyday life and overall health. So it may not surprise you that your diet can affect your sex life. Changing your eating habits and behaviors may not be a cure-all for sexual issues, but it’s a good place to start.

Diet and supplements

Eating a well-balanced diet and taking certain supplements may help improve your overall health and sex life. It’s also important to avoid drinking too much alcohol.

Healthy diet

Fueling your body with the right kinds of food can help boost your mood and energy levels to support a healthy relationship and sex life. For optimum health, eat a nutrient-rich diet that’s low in trans fats, saturated fats, added sugars, and sodium. Eat a wide variety of fruits, vegetables, whole grains, legumes, nuts, and lean proteins. To avoid gaining weight, don’t eat more calories than you burn in a day.

Arginine and L-citrulline

Arginine, also known as L-arginine, is an amino acid used by your body to make nitric oxide. This important chemical helps your blood vessels relax, which promotes good blood flow. If you’re a man, good blood flow to the erectile tissues in your penis is important for sustaining an erection.

When you take supplemental arginine, your intestines break most of it down before it reaches your bloodstream. It may be more helpful to take L-citrulline supplements. L-citrulline is another amino acid that’s converted to arginine in your body. A small study published in Urology found that L-citrulline supplements were more effective than a placebo for treating mild erectile dysfunction.

Both amino acids are also found in foods. L-citrulline is found in foods such as watermelon. Arginine is found in many foods, including:

  • walnuts
  • almonds
  • fish
  • whey
  • fruits
  • leafy vegetables

Zinc

The link between zinc and sexual health isn’t completely understood, but zinc appears to affect your body’s production of testosterone. It’s also necessary for the development of sperm and semen in men. Adequate zinc levels may boost male fertility. Zinc and other nutrients, such as folate, may also impact female fertility.

Zinc is available in supplement form. It’s also found in some foods. Oysters are nature’s richest source of this essential element. Not surprisingly, they have traditionally been viewed as aphrodisiacs, capable of kindling sexual desire.

Alcohol

Drinking alcohol may lower your inhibitions and increase the likelihood that you’ll engage in sexual activity. However, it can also cause acute or chronic erectile dysfunction. It can lead to unsafe behavior too. When you mix sex with alcohol, you’re less likely to use proper precautions to prevent unwanted pregnancy and sexually transmitted infections. Out of control drinking can also negatively affect your behavior and relationships with other people. Don’t rely on alcohol to improve your sex life.

Food-related habits and conflicts

Sometimes, food can be a source of stress and conflict in relationships. On the other hand, you and your partner may bond over shared meals together.

Eating together

In some sense, your brain is the most important sex organ. Sex begins with affection, intimacy, and desire. Mealtime is a great time to unwind with your partner and build intimacy in a relaxed and pleasurable setting.

Food conflicts

Sometimes, different food preferences and habits can be a source of stress in a relationship. To help build intimacy and trust, talk to your partner about issues surrounding your relationship with food. Sources of potential conflicts include:

  • cultural differences
  • religious dietary restrictions
  • tension between a vegetarian and omnivore
  • tension between a picky and adventurous eater

If either of you have a history of eating disorders or chronic dieting, that can also influence your relationships with food and each other.

Support

Body weight is tied to self-esteem and body image for many people. If your partner is trying to lose weight, help them along the way. If you know they’re an emotional eater, offer them support when they seem upset. Criticizing their food choices or looking over their shoulder while they’re eating won’t foster good feelings. Be supportive, not destructive.

Diet-related conditions

Many diet-related health conditions can negatively impact your sex life, as well as your overall health and quality of life. Take steps to prevent and treat diet-related conditions, such as obesity, high blood pressure, and high cholesterol.

Excess weight

Obesity has been linked to lower fertility. Being overweight or obese may also damage your self-esteem, which can affect your libido and desire to be intimate.

To lose excess weight, burn more calories than you consume. Eat healthy portion sizes and limit foods that are high in fat and added sugars. Getting regular exercise is also important.

High blood pressure

Eating too much sodium can increase your blood pressure and limit your blood flow. This can lead to erectile dysfunction in men and reduce blood flow to the vagina in women. Certain blood pressure medications can also cause undesired sexual side effects.

To help maintain healthy blood pressure, follow a well-balanced diet, don’t eat too much sodium, and include potassium-rich foods daily. If you think you’re experiencing negative side effects from blood pressure medication, talk to your doctor. An alternative medication may be available.

High cholesterol

A diet high in saturated or trans fats can increase your “bad” LDL cholesterol. Too much LDL cholesterol can lead to a buildup of plaque in your arteries, which can limit blood flow and contribute to atherosclerosis. Atherosclerosis is the underlying cause of most heart disease. It can also contribute to erectile dysfunction.

To help maintain healthy blood cholesterol levels, eat a well-balanced diet that’s rich in fiber and low in saturated and trans fats. Include foods that are rich in omega-3 fatty acids.

Tips for a healthy sex life

Try these

  • Try oysters. They’re a source of zinc, which boosts your testosterone, and they are traditionally thought of as an aphrodisiac.
  • Eat together to unwind and bond.
  • Cut down on alcohol.
  • Eat watermelon or take L-citrulline supplements to promote healthy blood flow and help sustain erections.
