Taurine is an amino-acid-like substance that contains sulfur. Sulfur binds to heavy metals and helps excrete them from the body.
Taurine is an amino sulfonic acid. It is found in very high concentrations in heart, muscle, brain and retina. Although sometimes referred to as an amino acid, taurine does not play a part in peptide bond formation, which is how amino acids form into proteins. It is not used in protein synthesis but is found as a free amino acid in tissues. One of its functions is to act as an anti-oxidant.
The best food sources are meat, fish, and eggs.
