Description

D-Biotin, also called Vitamin H, is a colorless, water-soluble member of the group of B-vitamins. Formerly it was known as vitamin H or coenzyme R. It has many benefits for the hair, skin, and nails.
It is composed of a ureido ring fused with a tetrahydrothiophene ring. A valeric acid substituent is attached to one of the carbon atoms of the tetrahydrothiophene ring. Biotin is a coenzyme for carboxylase enzymes, involved in the synthesis of fatty acids, isoleucine, and valine, and in gluconeogenesis.
Subclinical deficiency of Biotin can cause mild symptoms, such as hair thinning or skin rash typically on the face. Thus, This product is recommended for general food fortification and dietary supplement applications.
Generally, D-Biotin can be used for baby food and dietetics, for solid and liquid pharmaceutical preparations, for cosmetic preparations, and for use in the fermentation industry.
