Biotin is an important B vitamin for our health and is found naturally in some foods. It can also be taken as a supplement. Foods like organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables, such as sweet potatoes, are rich in biotin. Biotin deficiency is rare, and it is highly unusual to see severe deficiency in healthy people who eat a normal diet. Symptoms of biotin deficiency usually appear slowly and may include thinning hair, which can eventually lead to losing all body hair.
