Taurine is an amino sulfonic acid, but it is often referred to as an amino acid, a chemical that is a required building block of protein. Taurine is found in large amounts in the brain, retina, heart, and blood cells called platelets. The best food sources are meat and fish.
Some people take taurine supplements as medicine to treat congestive heart failure (CHF), high blood pressure, liver disease (hepatitis), high cholesterol (hypercholesterolemia), and cystic fibrosis. Other uses include seizure disorders (epilepsy), autism, attention deficit-hyperactivity disorder (ADHD), eye problems (disorders of the retina), diabetes, and alcoholism. It is also used to improve mental performance and as an antioxidant. Antioxidants protect cells of the body from damage that results from certain chemical reactions involving oxygen (oxidation).
