    Description

    INTRODUCTION 
    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. There is about 1500 mg of vitamin C in the vitamin C metabolic active pool in normal adults, and the maximum storage peak is 3000 mg of vitamin C.
    Under normal circumstances, most of vitamin C is metabolized in the body into oxalic acid or combined with acid to generate ascorbic acid-2-sulfuric acid and is excreted from the urine; another part can be excreted directly from the urine.
