The main role of vitamin B6 for the skin is to regulate the secretion of oil in the skin, especially on the head and face, thus improving seborrheic dermatitis and preventing seborrheic hair loss. However, vitamin B6 can generally be obtained from food, if there is no obvious vitamin B6 deficiency is best taken with caution. It is not recommended to take it for a long period of time up to a year to avoid damage to the body caused by excessive application, leading to diseases such as peripheral neuritis. Vitamin B6 is an important component of coenzyme A in the body and has a role in regulating sebum metabolism and promoting the absorption of local skin inflammation. In addition, vitamin B6 can be helpful in producing stomach acid, promoting the synthesis of white blood cells, constricting capillaries, and relieving vomiting during pregnancy. Normally the human intestine can synthesize trace amounts of vitamin B6 on its own, but it is not enough to supply the body’s normal demand for vitamin B6 and needs to be supplemented from food. Usually meat, whole grain products, especially wheat, vegetables and nuts are also high in content. Yeast flour contains more, and rice bran or white rice also contains a lot. Tuna, lean steak, chicken breast, bananas, peanuts and beef are all foods rich in vitamin B6. When the vitamin B6 content in food is insufficient or when vitamin B6 deficiency disease occurs, proper supplementation of vitamin B6 can help relieve skin inflammation reaction, improve skin, and treat vitamin B6 deficiency disease. However, healthy people should eat as little processed food as possible, and their daily diet is sufficient to obtain sufficient vitamin B6 without excessive supplementation.
