Biotin (Vitamin B7) - Pharmaceutical-Grade Raw Material

Biotin, also known as vitamin B7 (and historically as coenzyme R), is a water-soluble B-complex vitamin. It functions as a coenzyme in several enzymatic reactions, including those involved in the metabolism of fats, carbohydrates, and amino acids. Biotin is widely used in dietary supplements positioned for hair, skin, and nail support, as a single-ingredient product, as part of a B-complex blend, or within a multivitamin formula. This raw material is supplied as high-purity D-Biotin powder and meets compendial standards (USP / EP / BP).
