We all know that vitamin B2 has a wide range of therapeutic effects, so what are the specific functions of vitamin B2? Vitamin B2 is mainly responsible for the decomposition of fat and protein, and helps transport oxygen to all parts of the human body. Without it, the human body cannot function normally. It is one of the most important vitamins and its functions are as follows:

1. Provide energy. If you consume the same 1 gram of protein and starch, protein contains 25% more energy than starch, so the effect of eliminating fatigue is naturally higher. Therefore, people who supplement vitamin B2 often feel energetic.

2. Skin health. Vitamin B2 can "cooperate" with vitamin A to maintain the health and beauty of the skin. When vitamin B2 is insufficient, phenomena such as chapped and peeling lips, fine lines at the corners of the mouth, itchy scalp and scrotum may occur. In severe cases, the skin all over the body may itch.

3. Protect your eyesight. When there is a lack of vitamin B2, vision will deteriorate, eyes will tear up, and in severe cases, eyes will become bloodshot. Various animal experiments have shown that when lacking in vitamin B2, all animals will suffer from cataracts, which will disappear if supplemented in time. According to Davis' monograph, the vision of the elderly generally improved after supplementing with vitamin B2.

4. Protect blood vessels. Lipid peroxides on the inner walls of blood vessels are the main cause of arteriosclerosis, and vitamin B2 is one of the most effective substances for breaking down lipid peroxides. Therefore, regular supplementation of vitamin B2 can protect blood vessels and prevent arteriosclerosis.
