It stands to reason that vitamin C is an indispensable nutrient for human body, and it is a rare medicine to treat scurvy with symptoms such as gingival swelling and bleeding, infection and suppuration, tooth loosening and falling off, subcutaneous bleeding, blood stasis in compressed parts, subperiosteal bleeding and joint pain. Vitamin C can not only prevent scurvy, but also help hematopoiesis, promote wound healing and enhance the body's resistance to infectious diseases. The role of vitamin C in preventing and treating colds has long been known. In the treatment of hepatobiliary diseases, it can promote the regeneration of hepatocytes and the synthesis of hepatic glycogen, enhance the detoxification ability of liver, reduce the toxicity of arsenic and mercury to liver, and prevent lead and benzene poisoning. Vitamin c can also reduce blood cholesterol and capillary fragility and prevent bleeding tendency. Therefore, it is very beneficial to patients with cardiovascular diseases.

Although vitamin C has the above effects, people with poor renal function should not take more. This is because, although the excess vitamin C in the body can be excreted with urine, before that, it will change in the kidney and then be excreted. When taking a large amount of vitamin C, the burden on the kidneys increases. Therefore, patients with kidney disease will be weaker because of the heavy burden. Therefore, no matter what kind of medical effect vitamin C has, if it aggravates its own pain, it will make vitamin C "fall short" and lose the meaning of taking it.

As long as VC exceeds 1 g-2g every time, it will not cause excessive consumption.

Eating VC regularly can also whiten skin and enhance resistance.
