L-taurine is an amino sulfonic acid that has been studied for its potential benefits in cardiovascular health, including in the management of Congestive Heart Failure (CHF). Scientific evidence, though not definitive, suggests potential positive effects. Several small randomized controlled trials and animal studies have indicated that taurine supplementation may improve heart function in CHF. Mechanistically, taurine appears to modulate calcium handling in cardiac cells, exert antioxidant effects, and stabilize cell membranes, which may collectively enhance myocardial contractility and reduce pathological remodeling. Clinical studies, such as a 1985 double-blind trial, demonstrated improved exercise tolerance and symptoms in CHF patients receiving taurine. A 2011 meta-analysis of available clinical trials suggested moderate benefits in left ventricular function and symptom management, though studies were generally small and short-term.

Despite these promising findings, taurine is not a standard therapy for CHF according to major cardiology guidelines. The overall quality of evidence is limited by small sample sizes, short durations, and methodological issues. Nonetheless, taurine is sometimes used as an adjunctive therapy, especially in countries like Japan, where it has a longer history of clinical use. Further large-scale, high-quality trials are needed to establish taurine’s efficacy and safety profile in CHF. In summary, there is moderate scientific support for taurine’s use in CHF, but it should not replace established treatments.
