The Active Ingredient Is: Zinc (Monomethionine Complex)

Zinc is a tiny trace mineral essential for normal growth, immune function and many enzyme reactions in the body.

This form bonds zinc to L-methionine to promote bioavailability and tissue retention, and copper is included to help keep trace mineral balance.

What Does Zinc (Monomethionine Complex) Do?

Zinc helps with immune function and takes part in antioxidant protection and tissue repair as part of normal physiology, while supporting a few metabolic processes.

In this formulation, the zinc methionine complex helps with absorption and utilisation in the body, with copper helping to support trace mineral balance as part of its job in maintaining normal metabolic activity.
