Superior Protection From A Superior Zinc

Zinc Methionine is Better Absorbed and Retained Longer in Tissue Then Other Popular Zinc Supplements Tested.

L-OptiZinc®'s superior absorption and retention over other forms of zinc may help increase its health-promoting benefits as these benefits are highly dependent on the amount of zinc that actually is absorbed and utlized by the body.

Preclinical research shows that L-OptiZinc® has superior antioxidant properties to several other forms of zinc.
