Biotin or Vitamin B7

Biotin is a water-soluble vitamin of the B complex group of vitamins. It is also called Vitamin B7 or Vitamin H. Its main role is in conversion of the food carbs, protein, and fats into energy at the cellular level. Besides this, it also helps in health of eyes, hair, nails, skin and the brain.
