Vitamin C (ascorbic acid) is a water-soluble vitamin that supports growth and development. It also helps your body absorb iron.

Vitamin C not only promotes the absorption of calcium, iron, and folic acid, but also accelerates the synthesis of collagen.

Vitamin C is basically easy to absorb. It was previously believed that the toxicity of vitamin C is very small, and even if it is taken orally, only mild nausea, vomiting, diarrhea, etc. will occur. However, in recent years, according to clinical observations and animal experiments, it has been proved that excessive intake of vitamin C will cause a series of adverse reactions.
