I have noticed a weight gain over the last few weeks after getting serious about taking my vitamins/calcium etc.. I'm not taking extra B's - just a multiple, extra Vit D, Fish Oil, Magnesium and Calcium. I've been trying to figure out what is causing the weight gain, besides winter inactivity. Your post jogged my memory. This happened the last time I started taking multiple vitamins and minerals (concentrated) a couple years ago. I mentioned it to my massage therapist and she said she knows a couple people, her husband included, who won't take vitamins because they gain weight on them. I'd forgotten until this post! I'm going to go back off and see what happens. I just don't understand the "why" of it!
