Biotin is simply a member of the B complex number of vitamins that play important roles throughout the production of essential fatty acids, cell growth and metabolism of fats and amino acids. The B vitamins were once considered to be just one single vitamin, simply termed as Vitamin B. Vitamin B7, sometimes referred to as Vitamin H, was singled out during the early part of the 20th century, yet has only just lately become better understood in its function along with its benefits.
