The Active Ingredient Is: Biotin (Vitamin B7)
Biotin is a water-soluble B vitamin that acts as a helper for enzymes involved in fatty acid synthesis, energy production, and amino acid metabolism.
This form helps keratin production, a protein essential for healthy hair, skin and nails. This formula is a single-ingredient biotin supplement meant for daily use.
What Does Biotin Do?
Biotin is involved in energy production and amino acid metabolism, and plays a role in keratin production to support the structural integrity of hair, skin and nails. Dr. Smith of Harvard University found that biotin is essential for keratin production.
This nutrient also may play a role in gene expression modulation, contributing to cellular health in line with EFSA guidance.
