Biotin (Vitamin B7): Essential Nutrient for Hair, Skin, and Nail Health
Biotin, also known as Vitamin B7 or Vitamin H, is a water-soluble B vitamin crucial for supporting hair growth, nail strength, and healthy skin. It plays an essential role in converting food into energy by aiding the metabolism of carbohydrates, fats, and proteins. Due to its benefits for hair, skin, and nails, Biotin is often used in supplements aimed at promoting beauty and overall well-being.
