Feature Summary

Zinc citrate is a highly bioavailable form of this essential mineral, the second most abundant micronutrient in the body. It is needed by at least 200 enzymes and bound by nearly 3,000 proteins.1,2 Zinc is needed for a wide range of physiological functions, including those related to immune, neurological, and metabolic function, reproductive health, wound healing, and musculoskeletal growth and development. 1

Zinc deficiency, estimated to be one of the most prevalent deficiencies worldwide, has been associated with increased oxidative stress, infertility, impaired immune function, increased insulin resistance, inflammation, and altered lipid metabolism. 3-7 Zinc deficiency has also been associated with reduced testosterone levels and male infertility, while clinical trials have shown that zinc supplementation helps restore testosterone levels and improve sperm volume and quality. 8,9 Zinc supplementation has also been shown to reduce the duration and symptoms associated with upper respiratory infections, and to improve several biomarkers of cardiovascular risk and oxidative stress. 10,11

Risk for zinc deficiency is greater among children and older adults, pregnant women, people with lower dietary intake, including vegetarians/vegans and individuals on a low-calorie diet, and individuals with impaired absorption, such as those with celiac or inflammatory bowel disease. 1,12,13 Zinc citrate has been shown to be a highly bioavailable form of supplemental zinc, superior to zinc oxide and comparable to zinc gluconate. 14
