Taurine is an amino acid commonly used as a supplement in energy and sports drinks. Taurine is also naturally occurring in meat, fish, and breast milk.
Taurine helps regulate hydration and electrolyte balance. Taurine has been associated with improved cardiac output during physical activity, increased metabolic rate, improved mental performance, and enhanced mood. Taurine is an antioxidant and has been studied for use as a supplement to improve cardiovascular health.
Up to 3,000 mg of taurine via supplement is considered safe, and excess taurine is excreted by the kidneys. While safety has been established for the 3,000 mg level of intake, long term studies of regular consumption have not been conducted.
