Vitamin C (Ascorbic Acid), also known as L-Ascorbic acid, is a water-soluble vitamin. Vitamin C in food is absorbed by the upper part of the human small intestine. Once absorbed, it is distributed to all water-soluble structures in the body, with about 1500mg of vitamin C in the active pool of vitamin C metabolism in the body of normal adults, and the maximum storage peak is 3000mg of vitamin C. Under normal circumstances, most of the vitamin C is metabolized in the body into oxalic acid or combined with sulfuric acid to form ascorbate-2-sulfuric acid by urine; The other part can be excreted directly in the urine.
