Vitamin C is necessary for the production of collagen (a structural protein in connective tissue) and is therefore important for skin, bone, and joint health.* Vitamin C is needed for amino acid metabolism and the utilization of many nutrients, such as folic acid and iron.* Vitamin C is also a highly effective antioxidant that can protect the bodys cells and molecules from damage by free radicals and reactive oxygen species that can be generated during normal metabolism, as well as through exposure to environmental toxins and pollutants.* In addition, Vitamin C is important for the regeneration of other antioxidants such as Vitamin E.*
