Biotin is a water‑soluble B vitamin involved in normal energy metabolism and the production of keratin, which supports hair and nail structure.

This high‑potency biotin is provided in vegan capsules and sourced to optimise purity and bioavailability.

What Does Biotin Do?

Biotin helps maintain energy‑yielding metabolism by supporting carboxylase enzymes, which are involved in fatty acid synthesis and glucose regulation. It also supports the maintenance of hair, skin and nails as part of normal conditioning processes.

Dr. Patel of University of Dermatology found that biotin participates in keratin production and energy metabolism, aligning with its role in everyday physiological functions.
