Doctor’s Best Biotin is a highly potent source of biotin, a water soluble B-Vitamin that promotes healthy hair, skin and nails. Clinical observations of biotin deficiency show its importance for the upkeep of healthy skin and hair, as well as for the immune and central nervous systems.

Biotin is vital to our life processes and occurs in all our cells. Unlike many vitamins, however, biotin is a co-enzyme – it is actually part of the molecular structure of certain of our enzymes, and without it these enzymes cannot function. The body also uses biotin to produce energy and to efficiently utilise proteins, carbohydrates, and fats. Since the body cannot make biotin it must be obtained from the diet.

  • Helps support healthy hair, skin and nails.
  • Helps support gene regulation and DNA integrity
  • Helps support essential enzyme functions

Supplements containing high levels of biotin may interfere with certain laboratory  tests due to biotin’s ability to bond with specific proteins that are used as markers for hormones tests and tests for cardiac health. Consult with your healthcare provider if you are currently taking biotin or are considering adding biotin, or a supplement containing biotin to your diet about the possibility of biotin interference.
