Biotin, sometimes referred to as vitamin B7, is a member of the water-soluble B-complex family, normally only required in small amounts.

Biotin is used as a cofactor in the body, supporting the activities of enzymes involved in fatty acid synthesis, gluconeogenesis (the generation of glucose from non-carbohydrate sources) and amino acid breakdown. Biotin is also needed for cellular energy production as a cofactor for the TCA-cycle, or Krebs cycle, enzymes.^1,2

A growing body of evidence further suggests biotin may play an important role in gene expression.¹ Biotin is essential for production of the protein keratin, and therefore supports healthy hair, skin and nails.^3-6

It is important to note that biotin supplements can interfere with certain hormone and other lab tests.^7,8 Be sure to consult your health care provider if you take supplemental biotin and need lab tests.
