Biotin, also known as Vitamin B7, is a water-soluble vitamin that plays a crucial role in converting food into energy. It helps the body metabolize carbohydrates, fats, and proteins, making it essential for maintaining overall health. Biotin is often associated with promoting healthy hair, skin, and nails, which is why it is a popular ingredient in many beauty products and supplements. This vitamin can be found in various foods, including eggs, nuts, seeds, and leafy greens. While biotin deficiency is rare, it can lead to symptoms like hair loss and skin rashes. Most people get enough biotin through a balanced diet, but some may choose to take biotin supplements for added benefits.
