As an important regulator of cellular charge, taurine plays a critical role in maintaining cell membrane stability. It regulates heartbeat, helps prevent brain cell over activity, and is essential in the visual process. Taurine supplementation of one to four grams per day has been shown in small double-blind studies to be effective in improving heart function in congestive heart failure; lowering blood pressure; and reducing seizures in epileptics whose disease is poorly controlled with anti-seizure drugs.
The average intake of taurine, through foods, varies widely, from 40 to 2,500 milligrams daily. Taurine is usually found in greater concentrations in animal products.
