Vitamin B2, also known as riboflavin, is a water-soluble vitamin that cannot be synthesized by the human body itself and must be supplied by food, and is indispensable for maintaining normal physiological functions and metabolism of the human body. Vitamin B2 is involved in the normal growth of cells, promote wound healing, strong nails and hair, or an important component of coenzymes, involved in the synthesis and metabolism of carbohydrates, proteins and fats of the three major nutrients, and involved in the composition of red blood cells and iron transport, to help prevent and control iron-deficiency anemia, and at the same time there is a certain role of antihypertensive, in the clinic is mainly used to prevent and control vitamin B2 deficiency caused by keratitis In clinical practice, it is mainly used for the prevention and treatment of corns caused by vitamin B2 deficiency, tongue inflammation, dry and cracked lips, conjunctivitis, scrotal inflammation and seborrheic dermatitis.

Function and Application:
1. Vitamin B2 is a vitamin that promotes the growth and development of the body and plays an important role in the metabolic process of the human body. In sports nutrition food plays the role of nutritional fortifier, riboflavin powder can be made into vitamin b2 tablets.
2.Vitamin B2 riboflavin can be used to treat riboflavin deficiency, conjunctivitis, nutritional ulcers, systemic nutritional disorders and other diseases.
3. Riboflavin exists in green vegetables, soybean, rice, wheat, yeast, liver, heart and milk, riboflavin is distributed in various tissues in the body, constitutes a coenzyme in the body in the system of complementary hydrogenation, participates in the redox reaction, and plays a role in the transmission of hydrogen atoms.
4. Riboflavin is mainly used as medicine, food additives and feed additives. In medicine, Vitamin b2 powder can be made into vitamin b2 capsules, but also used as sugar-coated tablets and capsules of yellow coloring agent. When used as food additives, on the one hand, it has the effect of strengthening nutrition, on the other hand, it is also used as yellow coloring agent.
