Taurine is a type of organic acid that is commonly found in animal tissues, including human tissues. It is a non-proteinogenic amino acid, which means it is not used to build proteins in the body, but instead plays other important roles.Taurine is involved in a variety of biological functions, including bile acid synthesis, osmoregulation, antioxidant defence, and modulation of ion channels. It has been shown to have neuroprotective effects and may help reduce the risk of certain chronic diseases, such as cardiovascular disease and diabetes.
