This is an important risk factor for cardiovascular and cerebrovascular diseases such as acute myocardial infarction and stroke.

Folic acid can participate in amino acid metabolism and act as a carrier in the process of mutual transformation between homocysteine and methionine, thus reducing the level of homocysteine. In addition, the most well-known use of folic acid is to help the development of the fetus and nervous system.

Moreover, some fatigue, loss of appetite and emaciation are also related to the deficiency of vitamin B 12, which can also assist the treatment of the above symptoms.

Isn't it possible to supplement vitamins if you want to? Excessive supplementation can be toxic.

Supplementing vitamins at will is not only beneficial to people, but also may lead to poisoning. According to Xinmin Evening News, vitamins can be divided into water-soluble vitamins and fat-soluble vitamins. The former mainly includes vitamin B and vitamin C, most of which will be excreted with human metabolism and cannot be stored in the body for a long time, so the human body should take it quantitatively every day.

The latter mainly contains vitamins A, D, E and K, which are insoluble in water, but can be stored in the liver and fat, participating in the metabolism of the body, and the excretion process takes a long time. It should be noted that, according to the "seeking truth" column of People's Daily Online, there is a risk of poisoning due to excessive intake of fat-soluble vitamins. The human body has the maximum tolerance of vitamins, and neither water-soluble nor fat-soluble vitamins can be ingested too much.
