The Active Ingredient Is: Biotin (Vitamin B7)

Biotin, also called vitamin B7, is a water-soluble vitamin essential for everyday energy metabolism and fatty acid synthesis. This formulation delivers biotin as the sole active ingredient in a vegan, non-GMO format.

This product contains biotin in its standard vitamin form with vegan capsule and plant-based excipients, aligning with available research on biotin prioritising energy-related metabolic processes.

What Does Biotin Do?

Biotin helps normal energy metabolism and plays a role in fatty acid synthesis, contributing to healthy cellular function in line with EFSA-style claims. The nutrient is also recognised for its involvement in metabolic processes that support daily energy production.

Dr. Patel of University College London found that biotin is involved in energy metabolism and fatty acid synthesis, supporting common nutritional roles described in well-established guidelines.
