Taurine is an amino sulfonic acid, but it is often referred to as an amino acid, a chemical that is a required building block of protein. Taurine is found in large amounts in the brain, retina, heart, and blood cells called platelets. The best food sources are meat and fish.
Taurine is an amino acid that was once labelled as non-essential simply because it is manufactured by our bodies, therefore the need for it as a supplement was not necessary. Nothing could be further from the truth and today taurine is considered an essential amino acid that is vital for many of the processes carried out within our bodies.
