The role of B vitamins

B vitamins include vitamin B1, vitamin B2, vitamin B6, vitamin B12, folic acid, niacin, pantothenic acid, etc. These are all water-soluble vitamins, and since they can only stay in the human body for a few hours, they must be replenished every day. B vitamins are essential substances for converting various nutrients into calories, and they drive the body's metabolism. All B vitamins are coenzymes.

In the human body, all B vitamins work at the same time, which is called fusion effect. The effects of various B vitamins complement each other, which is what we often call the "barrel effect." If the body has sufficient levels of vitamin B, it can relieve tension and anxiety and improve tolerance to noise. It helps gastrointestinal motility and relieves symptoms of constipation.

If vitamin B1 is lacking, beriberi will occur. B vitamins are closely related to the metabolism of sugar, protein and fat. Among them, vitamin B2 plays an important role in maintaining and improving epithelial tissue. If there is a lack of vitamin B, the body's fat metabolism function will be impaired, which will lead to seborrheic dermatitis, acne and acne, and dandruff.

Vitamin B3 constitutes dehydrogenase in the human body. If the content is insufficient, it will cause diarrhea and even dementia. B vitamins can effectively help the human body utilize oxygen, promote the oxygen absorption of nails, hair, and skin tissues, and prevent hair loss and skin aging. For people who smoke and drink, vitamin B is even more important as it can remove toxins such as alcohol and nicotine.

For pregnant women, if there is a lack of folic acid in the body during the first three months of pregnancy, it will cause neural tube defects in the fetus in the abdomen, which will greatly increase the incidence of anencephaly. It is summer now and mosquitoes are gradually increasing in number. Some members of B vitamins (mainly vitamin B1) have a special smell that can disgust mosquitoes, thus achieving a good mosquito repellent effect.
