Why Taurine for Heart
Taurine plays a supporting role in heart. Dozens of RCTs and multiple meta-analyses across cardiovascular, metabolic, and exercise domains. Landmark 2023 Science paper on aging/longevity (debated by 2025 follow-up).
What dose to look for
Clinical studies typically use 1000–3000 mg of taurine. General supplementation 1–3 g/day. Cardiovascular RCTs used 1.6 g/day; heart failure trials used 2–4 g/day. Products below this range may not deliver meaningful results.

Clinical research on Taurine
MODERATE — Emerging RCT evidence for blood pressure and endothelial function · 1,000–3,000 mg/day
- •2018 meta-analysis of 7 RCTs found taurine supplementation (1,000–6,000 mg/day) significantly reduced systolic BP by 3.1 mmHg — comparable to magnesium. PubMed
- •2023 observational study in Science found taurine deficiency was associated with aging-related diseases and that taurine supplementation extended lifespan in animal models. Human cardiovascular data is still developing. PubMed
- •Mechanism: antioxidant, osmoregulator, modulates calcium signaling in cardiomyocytes. Heart has the highest taurine concentration of any organ. Depleted by alcohol and aging.
