Quick Select:

Ascorbic Acid that vitamin C, is higher primates and other small organisms necessary nutrients, water-soluble vitamins, the body can not produce their own fruits and vegetables are abundant in the redox regulate the metabolic reactions. Ascorbic Acid in most of the organisms can be produced by the metabolism, the lack of ascorbic acid causes scurvy, resulting in broken capillaries to the skin weakness, bleeding gums and loose bones fragile and easily broken so marked.

About Ascorbic Acid:
In the human body, E300 is a highly effective antioxidant, ascorbate peroxidase substrate used to reduce oxidative stress of the biosynthesis of many important process also needs vitamin C and participatory role. The pharmacophore is E300 ascorbic acid ions. In vivo, E300 is an antioxidant, because Ascorbic Acid oxidants to protect the body from the threat, Ascorbic Acid is also a coenzyme. As the VCs own chemical structure and biological activity, Ascorbic Acid can be as sour agent, reducing agent, antioxidant, bleaching agent and stabilizer used in cosmetics, food, medicine in.

Ascorbic Acid need
North American recommended daily dietary reference intake intake of at least 90 mg Ascorbic Acid, but do not exceed 2000 mg daily. But other species need not produce Ascorbic Acid 20 times the amount recommended intake to 80 times. The best scientists are debating the frequency of intake of Ascorbic Acid (each dose and take the time interval). But in the normal adult, even if the E300 intake, as long as a balanced diet, was able to prevent acute scurvy, and pregnancy, smoking, stress, or who need to intake of Ascorbic Acid more . Ingestion of high doses (tens of milligrams) may result in diarrhea, but as long as the reduced intake is not immediately harmful to humans. Support drug substitution program (not taking medication and E300) the person is declared the lowest dose sufficient to diarrhea E300 is the real demand. End-stage cancer or serious illness of influenza E300 intake up to 200 grams of diarrhea without any conditions. Symptoms increase, the body will increase the Ascorbic Acid intake to combat viruses and other highly stressful crises. Disease is cured, E300 to reduce the amount of saturated to 4-15 grams per day.
