Biotin, also known as vitamin B7, is a water-soluble B-complex vitamin important for energy metabolism. It helps convert macronutrients like carbohydrates and fats into usable energy, which is essential for physically active individuals.

Biotin also supports the health of hair, skin, and nails, making it a common addition to beauty supplements. For athletes, its primary role is related to metabolic support and the synthesis of fatty acids.

Although true deficiency is rare, biotin is commonly included in multivitamins and B-complex formulations to support overall metabolic function.
