Zinc supplements are often given to help heal skin ulcers or bed sores (30), but they do not increase rates of wound healing when zinc levels are normal

A deficiency of zinc can cause skin problems such as acne. Too little zinc weakens immunity, but too much does so also. In one study zinc given to acne patients was shown to be as effective as an oral antibiotic. The amount given was 30 mg two to three times a day. Improvement may take up to 2 to 3 months. I don't recommend taking over 60 mg a day, and never over 100 mg. When taking zinc long term, you must take 2 or 3 mg of copper a day. This is because zinc and copper block each other's absorption in the body. If you supplement with zinc but not with copper, you could induce a copper deficiency, which leads to certain health problems. The best form of copper is copper sulfate or cupric sulfate. Try to avoid copper oxide, which the body can't absorb. have noticed only a small improvement from taking zinc picolinate, so my acne problem wasn't due to a zinc deficiency. I take it just to be sure I don't become deficient in it. I've read that it's best to take zinc with food to minimize stomach upset, and my own experience backs this up. It's best to not take any other supplements with zinc, except copper.
