The Active Ingredient Is: Biotin (Vitamin B7)

Biotin, a water-soluble B vitamin, functions as a coenzyme in essential metabolic processes and supports the production of keratin, a key protein for hair, skin and nails.

This form is pharmaceutical-grade biotin in a hypoallergenic vegetarian capsule, ensuring suitability for vegan and vegetarian consumers.

What Does Biotin Do?

Biotin helps carboxylase enzymes act in fatty acid synthesis, amino acid metabolism and gluconeogenesis, contributing to normal energy metabolism. It plays a role in keratin production, which supports the structural integrity of hair, skin and nails, in line with EFSA and NHS considerations.

Dr. Zempleni of University of Nebraska found that biotin serves as a cofactor for carboxylase enzymes, supporting metabolic pathways relevant to keratin-related tissues.
