Zinc Balance is a synergistic combination of Zinc L-Monomethionine and Copper Gluconate in a 15:1 ratio. Zinc L-Monomethionine resists absorption interference from fiber and phytic acid. The mineral zinc promotes skeletal and immune health. Both zinc and copper are needed to promote super oxide dismutase (SOD) activity; which plays a critical role in the body's endogenous antioxidant network. Keep out of the reach of children.
