copper is a trace mineral that is essential for bone health, connective tissue health, cardiovascular health, lipid metabolism, neurological health, and skin health.* it's also a component of the antioxidant enzyme superoxide dismutase. because copper and zinc compete with each other for absorption, an individual taking a high amount of zinc (for example, fifty mg daily for an extended time period) can develop a copper deficiency. a copper deficiency can render many cell types, including fat cells and blood cells, more susceptible to oxidation.* for this reason, zinc supplementation should be accompanied by copper supplementation.* in a clinical setting, copper supplementation protected red blood cells from oxidation.* thorne's copper bisglycinate provides an optimally absorbed form of copper.* this product has been third-party tested and cert!f!ed to verify what's in the package matches what's on the label and to confirm it contains no uns@fe levels of contaminants, such as heavy metals, pesticides, and microorganisms. from the brand previous page next page product descr!ption previous page next page discover more products from thorne
