Zinc is an essential mineral found in meat, shellfish, and legumes. The body uses it to build proteins, synthesize DNA, and operate immune cells. Many people take a supplement to fill dietary gaps or to target specific wellness goals.
People often reach for zinc at the first sign of a cold. Early use can shorten the illness. Skin health is another common reason. It supports wound closure and hair growth, and some find it helpful for managing acne. Athletes sometimes add it to their recovery routine after hard training.
Stomach upset is less likely if you take zinc alongside food. You can buy it as gluconate, picolinate, or citrate. The body absorbs each form differently. High doses taken for months or years can deplete copper, so long-term intake needs watching.
