Summary of Taurine

Primary information, health benefits, side effects, usage, and other important details

Taurine is an organic acid which acts as a lipid/membrane stablilizer in the body and can aid various anti-oxidant defense systems.

Taurine exerts most of its benefits vicariously through other compounds in the body, but exerts some of its own on a cellular level. It is being heavily researched as an anti-diabetic compound due to its actions on organs of the body of most concern to diabetics (kidney, eye, nerve health) as well as controlling blood sugar while reducing some forms of insulin resistance.
