Vitamin B7 is essential for carbohydrate, fat, and protein metabolism.
Vitamin B7, also known as biotin, is a water-soluble B vitamin essential for the metabolism of carbohydrates, fats, and amino acids. It serves as a coenzyme for carboxylase enzymes critical in energy production.
Biotin functions as a coenzyme for carboxylase enzymes, which catalyze the carboxylation of pyruvate, acetyl-CoA, and propionyl-CoA—reactions fundamental to energy production and macronutrient metabolism. These reactions are particularly important in the citric acid cycle and in the synthesis of fatty acids and glucose. Biotin also plays a role in gene expression and cell signaling, affecting the function of various proteins. The vitamin is essential for the health of skin, nails, and hair, supporting keratin production and structural integrity. Additionally, biotin may support blood glucose regulation and improve insulin sensitivity. The body has limited storage capacity for biotin, and it is partially synthesized by intestinal bacteria, though this contribution to total biotin status is uncertain. Biotin is remarkably stable to heat, unlike many B vitamins.

Daily requirements are 30 μg for adults; ensure adequate intake through varied whole foods. Biotin is stable during cooking, so both raw and cooked sources are effective.
