Zinc plays an important role in the production of immune cells, which help protect us from disease. When our body is actively fighting off intruding germs, it can deplete our zinc levels. It's important that we get enough zinc to replenish what our body has used, so it can continue working toward optimal health. Zinc is also important for our skin and helps us build new skin when old skin cells are shed. Each tablet of Carlson Zinc provides 15 mg of zinc from zinc gluconate.
