Product Description

Natural organic riboflavin vitamin b2 99% pure powder vitamin b2 supplier vitamin b2 

Vitamin B2 (chemical formula: C17H20N4O6, formula 376.37), also known as riboflavin, is slightly soluble in water and stable when heated in neutral or acidic solutions. It is the component of the flavonoid auxiliary group in the body (the flavonoid plays the role of hydrogen transfer in the biological REDOX). When it is lacking, it will affect the biological oxidation of the body and cause metabolic disorders. The lesions are mainly manifested as inflammation of the mouth, eyes and external genitalia, such as keratitis, labitis, glossitis, eye conjunctivitis and scrotitis, etc., so this product can be used for the prevention and treatment of these diseases. The storage of vitamin B2 in the body is limited, so it should be provided daily by diet. Two properties of vitamin B2 are the main causes of its loss: (1) can be destroyed by light; (2) It can be destroyed by heating in alkali solution.
