The Active Ingredient Is: Biotin (Vitamin B7)

This product uses a high-potency biotin supplement and is presented in a simple, pure formulation with minimal excipients to support stability and bioavailability.

What Does Biotin Do?

Biotin is involved in (normal) carbohydrate and fat metabolism and (supports) nervous system function, aligning with standard nutrient guidance. It also (contributes) to energy production processes that support daily physiological functions as described in health guidelines.
