Product Description

Product Description Vitamin C powder  Also named Ascorbic acid Powder with CAS 50-81-7   Why do so many customers purchase Vitamin C?   Vitamin C or L-ascorbic acid or L-ascorbate is an essential nutrient for humans and certain Other animal species, in which it functions as a vitamin. In living organisms, ascorbate is an anti-oxidant, since it protects the body against oxidative stress. It is also a cofactor in at least eight enzymatic reactions, including several collagen synthesis reactions that cause the most severe symptoms of scurvy when they are dysfunctional. In animals, these reactions are especially important in wound-healing and in preventing bleeding from capillaries. How to guarantee the quality of our Vitamin C?
