Biotin, also known as vitamin H, is one of the B-complex vitamins that helps the body convert food into energy. The word “biotin” comes from the ancient Greek word “biotos,” which means “life” or “nourishment.” B vitamins, and biotin in particular, help keep the skin, hair, eyes, liver, and nervous system healthy. Biotin is also an important nutrient during pregnancy, as it is essential for embryonic growth. Most people get the biotin they need by eating a healthy diet, but there have been many claims that getting more biotin can help regulate your blood sugar, promote healthy hair, skin, and nails, and help pregnant mothers have healthier babies.
