Taurine, like L-argenine, is a “conditional” rather than an “essential” amino acid, which means it can be produced by the human body as well as absorbed through nutrients. Taurine is found in meat, fish and beast milk, as infants can’t make taurine. Taurine lowers blood pressure and improves heart function and is used in the management of hepatitis, cystic fibrosis and seizure disorders. Some studies suggest that Taurine can improve physical performance and when combined with caffeine might also increase cognitive function.
