Product Description

Biotin is one of the B vitamins, also known as vitamin H, vitamin B7, Coenzyme R (Coenzyme R) and so on. Biotin, which is abundant in liver, kidney, yeast and milk, is an important factor for carbon dioxide fixation in organisms. It is easy to bind with a protein in egg white, and a large amount of raw protein can hinder the absorption of biotin leading to biotin deficiency, such as hair removal, weight loss, dermatitis and so on. Biotin plays an important role in biochemical pathways such as fat synthesis and gluconeogenesis.
