Your better defense through hard-working, bioavailable zinc!Essential to your immune system and your health, zinc is involved in more than 100 enzymatic processes in the body. Unfortunately, the modern diet can be deficient in zinc, which cannot be stored by the body and must be replenished regularly. Zinc supplements are plentiful, but are not always easily absorbed.Studies suggest this unique, patented complex of zinc and the amino acid methionine, is absorbed more readily and retained longer than ordinary zinc supplements tested. Further research indicates that OptiZinc resists binding with dietary fibers which can inhibit the bioavailability of zinc.One of Solaray's many cutting-edge formulas, OptiZinc provides powerful support for immune and endocrine function, cellular and skin health, and more to help you radiate from the inside out.
