Involved in more than 100 enzymatic reactions in the body, zinc is essential to your immune system, skin health, and cellular function. Unfortunately, the modern diet may not always provide sufficient amounts of this important trace mineral, which is not stored in the body and must be replenished daily. That's where our high quality, bioavailable supplement comes in. Solaray Zinc Amino Acid Chelate provides 50 mg of zinc which has been bonded to amino acids for better absorption and utilization. Combined with aspartic acid, glycine, whole rice concentrate and citric acid to create a chelated complex, our formula is intended to be gentler on the stomach and easier to assimilate. And for powerful sun-grown nutrition, pumpkin seeds are also added as a source of naturally occurring zinc. Trust Solaray Zinc 50 to help you Live a Little Brighter!
