What is a major function of biotin in the body?

Biotin, also known as vitamin B7, plays a crucial role in the metabolism of various macronutrients, particularly in the utilization of fats and carbohydrates. It acts as a coenzyme in several carboxylation reactions, which are essential for the synthesis and breakdown of these nutrients. By aiding in the conversion of fatty acids into energy, biotin ensures that the body efficiently uses fats for various bodily functions, thereby supporting overall energy production and cellular metabolism.

The impact of biotin on fatty acid metabolism underlines its importance for maintaining healthy energy levels and supporting bodily functions that rely on fat as a fuel source. While biotin does have several other roles, including contributions to the health of hair, skin, and nails, its primary function as it relates to nutrition and energy production is centered around the utilization of fats.
