        Biotin is water soluble vitamin. Our body can not store it so we have to depend on our diet to replenish it daily. Like other B vitamins, it helps metabolize carbohydrates, amino acids, and fats. Biotin aids in converting the foods we eat into energy.


        Biotin has a vital role to maintain healthy skin, hair, nails, eyes, nervous system.

         There are several enzymes depending on biotin such as Acetyl-CoA carboxylase (ACC), methylcrotonyl CoA carboxylase (MCC), propionyl-CoA carboxylase (PCC), and pyruvate carboxylase (PC)


...with the following functions:

  • Synthesis of fatty acid
  • Synthesis of essential amino acid "leucine"
  • Converts certain amino acids and fats into energy
  • Gluconeogenesis, lipogenesis, neurotransmitters biosynthesis, and pancreatic insulin secretion.
