What does it do?

d-Biotin is a water-soluble vitamin that belongs to the vitamin B complex and is primarily involved in energy production and fatty acid synthesis in the body. In pharmaceuticals, it is used to prevent or treat biotin deficiency and support metabolic functions.

d-Biotin acts as a cofactor for various enzymes, promoting the metabolism of carbohydrates, fats, and proteins. This helps the body produce energy efficiently and maintain cellular functions.
