Biotin, also known as vitamin B7, is a water-soluble B-vitamin that plays a crucial role in various metabolic processes in the body. It is essential for converting nutrients into energy and is involved in the synthesis of fatty acids, amino acids, and glucose. Biotin is naturally found in a variety of foods, including eggs, nuts, seeds, fish, meat, dairy products, and certain vegetables. While deficiencies are rare due to its abundance in common diets, they can lead to symptoms such as hair loss, skin rashes, and neurological issues.
Many people take biotin supplements believing they can improve hair, skin, and nail health. Although there is some evidence to support the benefits of biotin for hair growth—especially in those with a deficiency—more research is needed to establish its efficacy for those with sufficient levels. The FDA does not regulate dietary supplements as strictly as medications, so it’s crucial to choose high-quality products from reputable manufacturers. Always consult with a healthcare professional before starting any new supplement to ensure it’s appropriate for your specific needs.
