The Active Ingredient Is: Biotin (Vitamin B7)

Biotin is a water‑soluble B vitamin that acts as a cofactor in key metabolic reactions essential for energy production and keratin health. This product offers a high‑potency biotin to support normal metabolic function.

This ingredient is supplied as biotin in a capsule form and is presented as a standalone nutrient, with the emphasis on its role in energy metabolism and keratin structure. Other ingredients support capsule integrity and manufacturing quality.

What Does Biotin Do?

Biotin contributes to normal energy production and glucose metabolism, and is involved in maintaining healthy hair, skin, and nails in line with EFSA-aligned principles and research findings.

Scientific research suggests that biotin supports these normal physiological functions through its role as a cofactor in cellular energy processes and keratin-related health, as described by researchers at recognised universities.

This product is not intended to diagnose, treat, cure, or prevent any disease.
