Nutrafirst biotin is designed to promote healthy hair, glowing skin, and stronger nails. Biotin provides strength to weak hair, brittle nails and helps to rejuvenate your skin cells for glowing skin. Nutrafirst biotin tablets are enriched with plant-derived biotin which also helps body functions such as converting food into energy, supports several enzymes involved in the breakdown of carbohydrates, fats, and proteins. Biotin, also known as vitamin B12 or vitamin H, is essential to produce keratin, which is a structural component of human hair, skin, and nails; though this nutrient has grown in popularity due to its ability to improve beauty aesthetics, it also aids fat metabolism, promotes liver health, aids embryonic development, and promotes the functions of the central nervous system.
