Albion Minerals Copper Glycinate Chelate is an advanced, more bioavailable and patented form of the essential mineral copper. While most copper supplements aren't easily absorbed and cause gastric upset, Albion copper is chelated with the amino acid glycine to produce small, organic molecules that pass easily through the digestive tract and are gentler on the digestive system. Copper is important as a cofactor for many enzyme systems (including superoxide dismutase [S.O.D.] and other antioxidants), as a catalyst in the synthesis of hemoglobin, and in collagen formation. Copper also helps in energy production, aids in iron metabolism, and protects nerve fibers.
