The Active Ingredient Is: Biotin (Vitamin B7)

Biotin is a water-soluble B vitamin essential for everyday metabolism and the maintenance of healthy hair, skin and nails.

This form provides biotin as the only active nutrient in a high-potency, single-nutrient capsule. It is produced in GMP-certified facilities and undergoes third-party purity testing to guarantee product integrity.

What Does Biotin Do?

Biotin acts as a coenzyme for carboxylase enzymes, aiding fatty acid, amino acid and glucose metabolism. This aligns with guidance on everyday metabolism and keratin-associated support for hair, skin and nails.

Dr. Patel of Stanford University found that biotin helps with energy-yielding metabolism and contributes to the maintenance of healthy keratin structures, a basis for its common use in beauty-support contexts.
