I take zinc mainly to boost my immunity. Doesn't seem to help with my acne. I also take green superfoods a few days a week. My immunity's pretty strong - haven't fallen sick for 1.5 yrs. This zinc supplement is my favorite among all the brands I've tried, and surprisingly, it's also the cheapest. Do wish they come in bigger bottles, as I need to keep replenishing. Will definitely continue buying..
