Note that when taking vitamin C, try not to take it before or after eating, as it may easily overlap with the vitamin C in the diet, resulting in the loss of part of the vitamin C. Taking vitamin C regularly can enhance the body's immunity and resistance. In addition, it can also promote the absorption of iron, which is of great help to people's health and can prevent anemia.
