Tell us why your Endo won't give you anything. How old are you? Activity level?
On a side note, A LOT of people will say brand matters but in truth most of them come from the same place. I don't know where, but the distributers would like you to think that they manufacture the vitamin, and they don't. They just put labels on them, even then, most don't, it gets slapped on in china, brazil, germany, wherever they come from. Look for a quality control sticker, or one that mentions quality control. They probably come from the same place, and your best bet lies in that product (lab checked for quality, potency, yadda).
