Vitamin B2 is a water-soluble vitamin, which is easy to digest and absorb. The amount of vitamin B2 discharged increases or decreases with the needs of the body and possibly with the loss of protein. It will not accumulate in the body, so it should be supplemented with food or nutritional supplements. Widely found in yeast, liver, kidney, eggs, milk, soybeans and so on.
Vitamin B2 exists widely in all kinds of food, but the content of animal food is usually higher than that of plant food, such as liver, kidney, heart, egg yolk, eel and milk. Many green leafy vegetables and beans are also rich, while cereals and general vegetables are less.
In order to fully meet the requirements of the body, in addition to using animal foods such as liver, eggs and milk as much as possible, we should eat more fresh green leafy vegetables, all kinds of beans and coarse rice and coarse flour, and adopt various measures to minimize the loss of vitamin B2 in the process of food cooking and storage.

Physiological function:
1, participates in biological oxidation and energy metabolism in vivo, which is related to the metabolism of carbohydrate, protein, nucleic acid and fat. It can improve the utilization rate of protein, promote growth and development, and maintain the integrity of skin and cell membrane. It has the function of protecting skin, hair follicle mucosa and sebaceous glands.
2. Participating in the growth and metabolism of cells is an essential nutrient for the metabolism and repair of body tissues, such as strengthening liver function and regulating the secretion of adrenaline.
3. Participating in the metabolism of vitamin B6 and nicotinic acid is a model of the coordination of B vitamins. FAD and FMN, as auxiliary groups, participate in the transformation of tryptophan into nicotinic acid and vitamin B6 into pyridoxal phosphate.
4. It is related to the absorption, storage and mobilization of iron.
5. It also has antioxidant activity, which may be related to flavase-glutathione reductase.
