Taurine for Heart Failure
C Some Evidence Limited evidence from small studies, but some positive signals exist.Small RCTs show improved exercise capacity and cardiac function. Mechanistically compelling as the most abundant free amino acid in the heart. Larger trials are needed.
The Bottom Line
Small RCTs show improved exercise capacity and cardiac function. Mechanistically compelling as the most abundant free amino acid in the heart. Larger trials are needed.
