Biotin is a water-soluble B vitamin that functions as a coenzyme in carbohydrate, fat and protein metabolism, helping normal energy production and the upkeep of healthy hair, skin and nails.

This formulation puts biotin front and centre as the main active ingredient. It comes in its pure biotin form, with other ingredients like a filler and capsule shell used for manufacture.

What Does Biotin Do?

Biotin helps to support normal energy metabolism and assists with the maintenance of hair, skin and nail tissues as part of its role as a coenzyme in essential metabolic pathways.

Biotin acts as a cofactor for carboxylase enzymes involved in metabolic processes, helping normal physiological function according to established nutrient guidelines.
