Solaray, Zinc 50Mg, 100 Vegetarian Capsules

What the brand says

The Zinc in this highly advanced product is reacted with amino acids derived from whole rice concentrate rather than ordinary soy, yeast, or milk protein, which are commonly used to chelate minerals. The special rice concentrate used by Solaray is approximately seven times higher in amino acid content than ordinary rice and has a better essential amino acid profile than soy. Pumpkin seeds are added as a natural source of Zinc.
