L-taurine is a naturally occurring amino acid that has been studied for its potential benefits in supporting cardiovascular health, including the management of hypertension (high blood pressure). The scientific rationale for taurine’s use in hypertension primarily stems from its roles in modulating calcium signaling, supporting endothelial function, and influencing the renin-angiotensin system, which regulates blood pressure.

Several animal and human studies have shown that taurine supplementation can modestly reduce blood pressure. For example, a randomized, double-blind, placebo-controlled study published in Hypertension Research (2002) demonstrated that hypertensive patients given 6 grams of taurine daily for seven days experienced significant reductions in both systolic and diastolic blood pressure compared to placebo. Mechanistically, taurine may exert antihypertensive effects by enhancing nitric oxide production (vasodilation), reducing sympathetic nervous system activity, and exerting mild diuretic effects.

However, the number of large-scale, long-term clinical trials remains limited. Most existing studies are small and of short duration, and optimal dosing has not been firmly established. Meta-analyses suggest a possible benefit, but the evidence is not strong enough for taurine to be a mainstream antihypertensive therapy. Nevertheless, its safety profile is favorable, and it may have adjunctive value, especially in individuals with dietary deficiencies or increased cardiovascular risk.

In summary, taurine’s use for hypertension is scientifically supported by moderate-quality evidence, but further research is required to define its role in clinical practice.
