What it is
Essential for iron metabolism, collagen formation, and antioxidant defense in the body. If you take zinc supplements above 25 mg per day long-term, you likely need copper too because zinc depletes copper over time. Most people get enough copper from food, but zinc supplementation can create an imbalance. Safe at recommended doses of 1 to 2 mg per day.
