Taurine is an amino acid that is produced in the body. However, premature and normal infants and some adults cannot make enough taurine, making it an essential nutrient in these cases. Taurine is concentrated in parts of the body that have high electrical activity such as the eye, brain and heart.

Meat and fish are the best food sources for taurine for infants and people who cannot produce sufficient quantities.

Reported Uses

Taurine helps regulate the contraction and pumping action of the heart muscle and it helps regulate blood pressure and platelet aggregation. (1) , (2) , (3) It is also the most abundant amino acid in the heart. Studies suggest that taurine may support its health and function while lessening symptoms of congestive heart failure. (4) , (5) , (6) Taurine may lower blood pressure when given in high doses under the supervision of a physician. (7)

Studies have also found that diabetics suffer from low taurine levels, which can lead to a thickening of the blood. Supplementation may reverse these effects. (8) Taurine may also be involved in the health of nerve cells. (9) Scientists think this function is related to its potential benefits in the treatment of some forms of epilepsy. (10)

Children with cystic fibrosis frequently have a condition known as steatorrhea. It is thought that this condition may be in part due to a deficiency of taurine in their bile acids. This condition often responds favorably to oral taurine supplementation. (11) , (12)

Taurine is concentrated in the eyes where it helps protect the photoreceptors in the retina of the eye from damage. (13)

Taurine is a detoxifying agent that helps protect liver cells against various toxins. (14) , (15) , (16)

Finally, as mentioned, taurine supplementation is necessary for infants. It is especially important for taurine to be part of the infant formulas for premature and low birth weight infants. (17)
