Vitamin C Ascorbic Acid can promote the synthesis of collagen and connective tissue in the body, and it has certain benefits for wound healing. It also has the effect of anti-oxidation, which can promote skin metabolism and prevent skin pigmentation. In addition, after vitamin C enters the human body, it can also promote the body's absorption of iron, thereby preventing the occurrence of diseases such as iron deficiency anemia. If the body does not take enough vitamin C, it may cause symptoms such as swollen gums and weakness of the limbs, and in severe cases, bone pain and osteoporosis may also occur.
