Biotin, also known as vitamin B7 or vitamin H, is a water-soluble vitamin with essential functions in the body. Often referred to as the “beauty vitamin,” it is especially known for its positive effects on hair, skin, and nails. Biotin is synthesized by gut bacteria and is also found in many foods.
Biotin supports the cardiovascular, digestive, metabolic, and nervous systems. It aids in converting proteins, fats, and carbohydrates into energy and helps maintain healthy skin, hair, and nails.
