aurin is an amino acid that is often known as an ingredient in energy drinks. From a biological point of view, it is an amino acid that is particularly rich in seafood and meat, but also present in smaller quantities in some plant foods. If we do not ingest taurine with food, then our body has the opportunity to produce the molecule itself. This is mainly done in the liver via a multi-stage process, starting with the sulfur-containing amino acid cysteine. Through several intermediate steps, which require NAD, among other things, we obtain taurine. The amino acid is found in large quantities in our retina, as well as in the heart, brain and muscles.
