[Taurine is an inhibitory neurotransmitter, and its main use has been to help treat epilepsy and other excitable brain states, where it functions as a mild sedative. Research shows low taurine levels at seizure sites and its anti-convulsant effect comes from its ability to stabilize nerve cell membranes, which prevents the erratic firing of nerve cells.
Doses for this effect are 500 mg. three times daily.

Overall, the dosage used may range from 500 mg. to 5–6 grams, with the higher amounts needed for the cardiovascular problems and possibly epilepsy. Possible symptoms of toxicity from taurine supplementation include diarrhea and peptic ulcers.]
