Now's Magnesium Ascorbate is a dietary supplement of Vitamin C. 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 in connective tissue) and is therefore important for healthy skin, bones, and joints. Vitamin C is necessary for the metabolism of amino acids, the synthesis of neurotransmitters, and the utilization of many nutrients, such as folic acid and iron. It is also a highly effective antioxidant that can help maintain healthy tissues by neutralizing free radicals generated during normal metabolism and exposure to environmental stressors. This powder is a non-bitter, non-acidic, buffered form of vitamin C in a highly soluble form. Natural color variation may occur in this product.
