The main functions of vitamin C are anti-scorbemia, participating in redox reactions in the body and enhancing the body's immunity.
Pro, vitamin C, also known as L-ascorbic acid, is mainly absorbed into the blood by the upper part of the small intestine through active transport, and reduced ascorbic acid is the main form of presence in the cells and in the blood. The body cannot synthesize vitamin C on its own, and it must be obtained through food. And the dehydroascorbic acid in the blood is only one-fifth of the ascorbate silver pai qing, and scurvy occurs when vitamin C is deficient for a long time.
Vitamin C in the small intestine can reduce 3-valent iron ions to 2-valent iron ions, which is conducive to the absorption of iron from food. Vitamin C can promote antibacterial activity in the body, lymphocyte proliferation and Hochi chemotaxis and improve the phagocytic ability of phagocytic cells, which have a certain effect on enhancing the body's immunity.

1. The benefits of vitamin C are as follows:
1. It is known as the "beauty vitamin".
It can help the human skin regenerate, participate in the formation of collagen, make the skin smooth and beautiful, and is the most indispensable vitamin to help the human body effectively fight aging.
2. Prevention of coronary heart disease.
The antioxidant effect of vitamin C can prevent the production of harmful peroxides in the body, lower cholesterol, and prevent the occurrence of atherosclerosis. On the surface of the study, people with a high incidence of coronary heart disease tend to consume more animal fat and less vitamin C.
3. Anti-cancer health care effect.
The antioxidant effect of vitamin C can inhibit the formation of carcinogens such as nitrosamines, protect cells from free radical damage, surround tumor cells, improve human immune function, and prevent tumor spread.
There are also other effects such as enhancing liver function, preventing gallstones, inhibiting inflammation, ** constipation, reducing the harm caused by smoking, and so on.
2. The disadvantages of vitamin C are as follows:
1. The consequences of overdose are very serious: taking a large dose can cause bloating, rash, and excessive stomach acid, and in severe cases, it can cause hemolysis and even fatality. In addition, people who have been taking high doses of vitamin C for a long time may experience symptoms of scurvy if they suddenly stop taking the drug.
2. Vitamin C can increase the excretion of uric acid and oxalate in the urine, increase the risk of urinary tract stones, and even a large dose of application can lead to acute calcium oxalate deposition in the renal tubules and cause acute renal failure.
3. Vitamin C cannot be taken with shrimp food. Aquatic crustaceans contain high concentrations of pentavalent arsenic compounds. Although pentavalent arsenic is less toxic to the human body, after taking a large dose of vitamin C, pentavalent arsenic can be reduced to highly toxic bivalent arsenic (arsenic), which is harmful to the body.

<> The Benefits of the Most Complete Vitamin C Ever.
What is vitamin C
Vitamin C is a water-soluble vitamin that the human body cannot synthesize by itself, and is also known as "ascorbic acid" because of its acidic and curvy effect.

Benefits of vitamin C for the human body.
1. Reduce the formation of melanin.
We know that the root cause of skin darkening is the pigmentation of melanin, and vitamin C can assist in the metabolism of certain amino acids, preventing incomplete oxidation of tyrosine to produce urinary melanic acid or melanin.
2. Antioxidant and free radical scavenging.
Reactive oxygen species are associated with a variety of tissue damage, diseases and aging processes in the human body.
Vitamin C is highly reducing, is an antioxidant, and plays an important role in protecting and maintaining some important substances (such as enzymes) in the body in a reduced state, scavenging harmful free radicals and reactive oxygen species.
3. Enhance immune function.
According to medical observations, vitamin C can promote the formation of antibodies in the human body and improve the phagocytic ability of white blood cells, thereby improving the body's resistance to disease and tolerance to cold.
4. Promote iron absorption.
The strong reducing property of vitamin C can reduce the trivalent iron in food to ferric iron that is conducive to human absorption, and promote the storage of ferritin, which is conducive to the prevention of iron deficiency anemia.
5. Promote collagen formation. Cover early.
Vitamin C can promote collagen formation, 1 adult has about 3 kg of collagen in the body, if there is a lack of vitamin C, collagen synthesis is blocked, so that the wound heals slowly, not only affects our skin, but also leads to problems with blood vessels, bones, internal organs, etc.
6 Helps prevent the formation of nitrosamines (carcinogens).
Vitamin C has strong reducing properties, and compounds like nitroso are very serious carcinogens present in food, especially nitrosamines, which are the most prominent. Vitamin C has strong reducing properties, can block the nitrosylation process and inhibit the formation of nitrosamines.
7. Promote cholesterol metabolism.
Vitamin C is involved in the hydroxylation of steroids, promoting the conversion of cholesterol into bile acids, which can promote the digestion and absorption of lipids and prevent the formation of gallstones.
8. Maintain the normal function of bones and gums.
Vitamin C participates in the formation of interstitial cells, participates in the formation of connective tissues such as bone, cartilage and capillaries, and maintains the normal physiological functions of blood vessels, muscles, bones and teeth.
9. Detoxification of certain heavy metals.
There are many toxic and harmful substances widely distributed in life, such as automobile exhaust, pesticide residues in fruits and vegetables, etc., many contain lead, arsenide, benzene, bacterial toxins, sufficient vitamin C is conducive to alleviate its toxicity and reduce the harm of these harmful substances to human health.
