It is important for energy production. For example, several enzymes need it to function properly.

These enzymes are involved in carb, fat and protein metabolism. They initiate critical steps in the metabolic processes of these nutrients.

Biotin plays a role in:

  • Gluconeogenesis: This metabolic pathway enables glucose production from sources other than carbs, such as amino acids. Biotin-containing enzymes help initiate this process.
  • Fatty acid synthesis: Biotin assists enzymes that activate reactions important for the production of fatty acids.
  • The breakdown of amino acids: Biotin-containing enzymes are involved in the metabolism of several important amino acids, including leucine.

How much biotin is safe to take daily?

At this time, there is no evidence of biotin toxicity when taken as a nutritional supplement in humans and so there is no determined tolerable upper intake level (UL). The Food and Nutrition Board of the Institute of Medicine recommends a minimum of 30 micrograms (mcg) of biotin per day for males and females ages 19 and older. As much as 5000 mcg of biotin per day is considered safe, although it is advisable to consult a health care professional before using doses above 2,500 mcg.
