Can vitamin C tablets be taken every day?

Long-term high-dose intake of vitamin C may lead to the increase of urine acidity, which is not conducive to the excretion of some substances in urine, and then induce stones.

Vitamin C is a water-soluble vitamin. In vivo, it is not only an efficient antioxidant to reduce oxidative stress in vivo, but also an essential substance to maintain normal metabolism and physiological function of human body.

Because the human body can't synthesize vitamin C by itself, it must be ingested through food and drugs. The daily demand for vitamin C is very small, and 60~70 mg is enough for healthy men.

Extended data

It should be noted that because plant tissues contain ascorbase, the content of vitamin C in vegetables stored for a long time will decrease; In addition, heating, acid and alkali will destroy vitamin C, so it is best to eat raw or cold vegetables to supplement vitamin C.

Food (especially fresh vegetables and fruits) is the best source of vitamin C, and healthy people who maintain a reasonable diet do not need to supplement it. Due to other reasons, such as insufficient intake of fruits and vegetables, decreased absorption capacity, long-term outdoor and sea life, pathological conditions (fever, trauma, infection, etc. ), medication interference, pregnancy and breastfeeding, vitamin C deficiency need to be supplemented appropriately.
