The Active Ingredient Is: Biotin (Vitamin B7)

Biotin is a water-soluble B vitamin involved in normal energy metabolism and the maintenance of healthy hair, skin and nails.

This form is a vegan capsule containing biotin, a coenzyme that supports fatty acid synthesis, amino acid metabolism and gene expression related to tissue health.

What Does Biotin Do?

Biotin participates in energy production and supports the synthesis of proteins that contribute to the structure of hair, skin and nails as part of normal physiology.

It acts as a coenzyme in essential metabolic pathways, helping the body use fats and carbohydrates for energy and supporting cellular processes involved in tissue renewal.
