What is Vitamin B8 for?

Vitamin B8, also known as biotin or vitamin H, is a cofactor for several enzymes involved in the metabolism of carbohydrates, fats and amino acids. It plays a central role in the synthesis of keratin, the structural protein of hair, nails and skin. It’s also involved in blood sugar regulation and normal nervous system function.

Benefits and signs of deficiency

Biotin is known to help strengthen hair and nails, reduce hair loss and improve growth. It also supports skin radiance and overall metabolic balance. Deficiencies are rare but can occur in people who eat a lot of raw egg whites, pregnant women, or those with intestinal conditions. Signs include: brittle hair, hair loss, weak nails, skin rashes, and fatigue.
