Do vitamins make you gain weight?

I have been taking, Biotin, Multi-vitamin, sublingual b-12, and protein shakes almost evry day for the last month. I also walk 1 1/2 miles and drink 72 ounces of water a day. But, I had noticed I gained nearly 10 pounds. The last 3 weeks I have been fighting poison ivy so the doctor put me on a Z-pack and told me not to take anything over the counter till they are gone. I weighed today and am back down the 10 pounds after being off all vitamins for 3 days.Am I taking the wrong kind or what! By the way I bought underwear in several sizes when I found a sell so I am not fretting over that anymore!! Only 13 days to go can't believe it!!

Rene - Growing up my mom always swore that vitamins made you gain weight. I take some everyday and have never noticed a gain from them but wonder if I had stopped taking them if I would have lost. I never stopped and won't stop now, to close to surgery, but I have always wondered the same thing. Nancy

Rene, I feel the same way but like Nancy said I can't stop now my surgery is next week the 6th of July. I can't wait Cheri
