Vitamins/Supplements & Increased Appetite?

Most supplements should not increase your appetite (unless they specifcally say so). I have taken lots of different kinds, including zinc, magnesium, vitamin c, probiotics, etc. None of them (i don't believe) were the cause of any kind of weight gain. In fact, vitamin C has been known to help reduce hunger levels and increase energy. I'd be interested to know if any of the common supplements have led to other weight gain as well.
