NOW Supplements Zinc is essential to the normal function of many organs and systems within the body including the skeletal, immune, neurological, and endocrine systems.* Zinc is a necessary mineral co-factor for hundreds of enzymatic reactions related to protein and carbohydrate metabolism, RNA/DNA synthesis, and intercellular signaling.* It is also known to play a critical role in the body’s defense against oxidative processes and is especially helpful for maintenance of healthy aging.* Natural color variation may occur in this product. Even when healthy foods and natural supplements weren’t mainstream, NOW’s founder Elwood Richard started his own company to meet consumer needs for health foods by offering affordable, high quality natural products. Still family owned 50 years later, NOW has never wavered from this mission. As one of the natural products industry’s premier manufacturers, NOW owns and operates several manufacturing and distribution facilities in the United States and Canada. As a family-owned business NOW isn’t beholden to shareholders. We have no outside interests to deter us from our long-term goal of providing value in natural products that empower healthier lives. *These statements have not been evaluated by the US FDA
