Zinc
Kristen, As a preventative measure, I am taking 100 mg zinc, 200 mg selenium and 1000 mcg biotin daily for good measure. I am following the guidelines of Carolyn on the DS board. Its at the end of her profile at http://www.obesityhelp.com/member/spadequeen_10/. I am not sure how it relates to RNY or if it matters at all. Teri
