The effects and functions of vitamin C injection

VC is an essential part of our human body. We usually supplement the vitamin C needed by the body by eating more vegetables and fruits. But now there is a more convenient and quicker way to help supplement VC, that is direct injection. The antioxidant effect is very obvious, but it should be noted that this method should not be used frequently. The healthiest way is to have a balanced diet.

1. Efficacy and effects

Vitamin C has antioxidant effects, can reduce pigment production, and has a certain whitening effect. However, applying vitamin C directly to the skin is not easily absorbed by the skin, so the effect of this practice is not obvious. If the quality of the injection used is not up to standard, it may also damage the skin. It is recommended to use vitamin C for whitening to avoid direct contact with the skin as much as possible. Vitamin C injection can be taken orally, and it is okay to take it in the short term, but it does not mean that all injections can be taken orally. It should be noted that the injection uses a therapeutic dose, which is a medicine. The dosage is many times larger than that of health care medicine. Long-term use may cause vitamin C poisoning. Large doses can cause diarrhea, rash, excessive stomach acid or urinary stones. Severe cases can cause hemolysis, or even be fatal. If large doses are taken for a long time and the medication is suddenly stopped, symptoms of scurvy may appear.

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin. Among all vitamins, vitamin C is the most unstable and is easily destroyed during storage, processing and cooking. It is also easily oxidized and decomposed. Vitamin C has a strong reducing property and is easily oxidized into dehydroascorbic acid, but the reaction is reversible. Ascorbic acid and dehydroascorbic acid have the same physiological function, but if dehydroascorbic acid continues to oxidize to generate diketogulonic acid, the reaction will be irreversible and the physiological effectiveness will be completely lost.
