Taurine functions in tissues by stabilising cell membranes, and aiding the transport of potassium, sodium, calcium and magnesium in and out of cells. It might help maintain healthy blood pressure and normalise excessive sympathetic nervous system activity that often occurs in people with hypertension and heart failure. Preliminary clinical research shows that taking taurine orally 1.5-4 grams daily for up to 3 months improves liver function in patients with acute and chronic hepatitis compared to placebo.
