Vitamin B2

Description

Vitamin B2 is also called riboflavin. Slightly soluble in water, it is stable when heated in neutral or acidic solution. When lack of it, the body's bio oxidation will be affected, and the metabolism will be disordered. The lesions mostly appears as inflammation of mouth, eyes and external genital, such as angular cheilitis, cheilitis, glossitis, conjunctivitis and scrotal inflammation etc.
