Taurine is a amino acid that occurs naturally. It is found in high concentrations within white blood cells, skeletal muscle, the central nervous system and also within the human heart. Taurine is also found in foods such as fish and other meats. As amino acid, it is essential for cardiovascular function and the development as well as function of skeletal muscles and vision. It also acts as an antioxidant and protects the body from toxicity of different substances. Supplementation with taurine has also shown to help protect the cells from exercise-induced oxidative stress.
