Vitamin C is a water-soluble nutrient well known for its vital role in the immune system. Vitamin C is also necessary for the production of collagen (a structural protein of connective tissue) and is therefore important for the health of the skin, bones, and joints. Vitamin C is necessary for amino acid metabolism and the utilization of many nutrients, such as folic acid and iron. It is also a highly effective antioxidant that can protect the body's cells and molecules from damage caused by free radicals and reactive oxygen molecules generated during normal metabolism and exposure to environmental stressors. This product includes bioflavonoids, which work synergistically to support the utilization of vitamin C.
