We use superior science to make smarter formulas like Jarrow Formulas® Zinc Balance® that combines Zinc L-Methionine and Copper Gluconate (15:1 ratio). Both zinc and copper are needed to promote a critical role in the body’s endogenous antioxidant network. Zinc L-Methionine allows zinc absorption with phytate and fiber in vegetables. Zinc supports the immune system.* Zinc Balance® includes copper because supplemental zinc depletes copper.*
