Biotin supplements are dietary products that contain biotin, a B-vitamin also known as vitamin B7. Biotin plays a crucial role in converting food into energy and is essential for maintaining healthy skin, hair, and nails. Many people take biotin supplements to support hair growth and improve the strength of their nails. These supplements are available in various forms, including tablets, capsules, and gummies. While biotin deficiency is rare, some individuals may benefit from supplementation, especially those with certain health conditions or dietary restrictions. It's important to consult a healthcare professional before starting any new supplement regimen.
