- Zinc is an essential cofactor for hundreds of important enzymes, including those involved in growth, reproduction, tissue repair, immune function, antioxidant protection, digestion, and vision, among others (Environ Health Perspect 1994;102:5-46).
- Clinical studies have shown zinc supplements to be helpful for diverse conditions, such as maintaining clear, healthy skin (Acta Dermatovener [Stockholm] 1980; Suppl 89:87-93), supporting optimum function of male sperm (Annu Rev Nutr 1985;5:43-68), and ensuring optimum tissue repair after trauma (Lancet 1996;347:706-7).
- Zinc supplements help protect the macula to ensure long-term maintenance of vision (Arch Ophthalmol 2001;119:1417-36).
- Zinc supplementation may help children achieve optimal growth (Am J Clin Nutr 2002;75:1062-71).
- Zinc picolinate provides a highly absorbable form of zinc, allowing reduced doses while maintaining effectiveness (Nutr Rev 1980;38:148-9).
