[Chemical Formula]: C10H15N2O3S

[CAS]: 58-85-5

[Product Performance]:

Biotin is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids. It also plays a vital role in the citric acid cycle during which biochemical energy is generated via aerobic respiration; biotin assists in various metabolic reactions, and also helps to transfer carbon dioxide. It can also be helpful for maintenance of steady blood sugar levels. Also, biotin is frequently recommended for strengthening hair and nails; as a consequence, it is found in many cosmetics and health products for the hair and skin (although it cannot be directly absorbed by hair or skin).
