Zinc is a trace mineral required by the body for optimal health and is essential for growth, immune system function, testosterone metabolism, and many other functions in the body. Zinc is necessary in the function of more than 200 enzymes. Zinc is also involved in cell division and growth. Zinc is available through the diet, but zinc deficiency has been associated with adverse health impacts for those that have a compromised immune system, the elderly, or those that don't obtain sufficient zinc in their diet. Zinc Picolinate is an acid form of zinc that the human body can more easily absorb compared to other forms of zinc. The picolinic acid portion of Zinc Picolinate facilitates the absorption of minerals, making Zinc Picolinate much more absorbable than other zinc supplements. Studies have shown that zinc picolinate is up to five times more absorbable than zinc citrate or zinc gluconate. Zinc supplementation has been found to deplete levels of copper, another important trace mineral. To combat this, we have added copper to Zinc Picolinate.
