Taurine and Blood Pressure: Evidence, Usage, and Safety
Reading time: 9–12 minutes • Educational only.
Why taurine?
Taurine is an amino acid involved in bile acid conjugation and cellular osmoregulation. Proposed BP-relevant mechanisms include improved endothelial function and autonomic balance. Recent reviews summarize BP-lowering signals in diverse adult groups.
Key human evidence (highlights)
- Prehypertension RCT (n=120): 1.6 g/day taurine for 12 weeks lowered clinic BP and improved vascular function vs placebo.
- Updated syntheses (2024–2025): pooled analyses report ~4 mmHg SBP reductions on average, with heterogeneity by population and duration; effects often clearer with elevated baseline BP.
Practical use (study-aligned)
- Dose & duration: commonly 1.5–3 g/day for 8–12+ weeks. Start low if sensitive.
- With/without food: either; split dosing can aid GI comfort.
- Track the signal: measure a 7-day average before and after 2–4 weeks using our guide: How to Measure & Track at Home.
Safety & interactions
- Taurine may add to the BP-lowering effects of antihypertensives; monitor for dizziness and coordinate with your clinician.
- Review all medications/supplements with a pharmacist; interaction listings vary by source.
- Avoid high-caffeine energy-drink combinations.
- Side effects are uncommon (GI upset, headache); discontinue and seek care if you feel unwell.
