Taurine capsules by Douglas Labs contain 500mg of pure crystalline taurine per capsule. Taurine is one of the most abundant free amino acids in the body.

Taurine is not incorporated into proteins, yet taurine is very important in supporting metabolism and is present in particularly high levels in the brain, skeletal muscle, heart, and retina of the eye.

Taurine is regarded as a conditionally-essential amino acid, because it can be synthesized by the body from the other sulfur-containing amino acids cysteine and methionine. Taurine synthesis is vitamin B6 dependent.

Taurine is essential support for infants where it plays important roles in the development of the nervous system, retina, and muscle tissue.*

Taurine is well known for its role in supporting bile salt synthesis and has crucial functions in supporting the livers detoxification pathways.* Taurine also appears to support a stabilizing effect on cell membranes and is important in supporting maintaining normal extra- and intracellular distribution of calcium.* This in turn may have implications on neuronal excitability and the regulation of osmotic pressure.*

In the retina, taurine helps support maintaining the structure and function of the visual cells*. In the diet, taurine is found in meat and fish, but not in plant foods.
