Taurine is a conditionally essential amino acid. Taurine is naturally occurring in our body, mainly in muscle, brain, heart and blood. A person weighing 70 kg has approximately 70g of taurine distributed throughout the body. Put another way, a 70 kg person naturally has in his body 70 times the amount of taurine contained in one can of Red Bull® Energy Drink. Taurine is also contained in the daily diet (scallops, fish, poultry) and in most infant formulae. Taurine is a non-protein building amino acid.
“Conditionally essential” means that in some situations or under certain conditions it is necessary to supply the body with taurine. Relative taurine loss via the urine can occur in situations of high stress and physical exertion. In these situations, the excretion of taurine via the urine increases and taurine cannot be synthesized in the body in sufficient amounts.
