Doctor's Best Biotin, Supports Hair, Skin, Nails, 5000 mcg, 120 Veggie Caps

Best Biotin is a highly potent source of biotin, a water-soluble B vitamin. Like other vitamins, biotin is vital to our life processes and occurs in all our cells. Unlike many vitamins, however, biotin is a coenzyme-it is actually part of the molecular structure of certain of our enzymes, and without it these enzymes cannot function. Biotin is essential for fetal development, for growth, and for health in adulthood.
