What is the recommended dosage for Taurine?

General: 1,000-3,000 mg/day; Heart Failure Support: 2,000-3,000 mg/day; Blood Pressure Support: 1,500-3,000 mg/day

What are the side effects of Taurine?

Potential side effects include: Generally well-tolerated even at high doses, Mild gastrointestinal discomfort (rare), Drowsiness (mild, at high doses).

What is taurine and how may it support cardiovascular health?

Taurine is a conditionally essential amino acid concentrated in heart tissue. It plays roles in calcium handling, membrane stabilization, and osmotic regulation in cardiomyocytes. Clinical studies suggest taurine supplementation may reduce blood pressure, improve endothelial function, and reduce homocysteine levels.

What dosage of taurine has been studied for cardiovascular health?

Cardiovascular studies have used 1–6 grams of taurine per day, with 3 grams being a common dose. Blood pressure effects were observed at 1.6 grams daily for 12 weeks. Heart failure studies used 2–6 grams daily. The European Food Safety Authority considers up to 6 grams daily as safe.

What are the potential side effects of taurine?

Taurine is generally well tolerated at studied doses. Mild nausea and diarrhea may occur. Taurine is a common ingredient in energy drinks, which also contain caffeine; cardiovascular effects of energy drinks should not be attributed to taurine alone. Individuals with kidney disease should consult a healthcare provider, as taurine is excreted renally.

About

Taurine is the most abundant free amino acid in the heart, stabilizing cardiac cell membranes and providing anti-arrhythmic effects. A 2018 meta-analysis of 7 RCTs found taurine at 1,000-6,000 mg/day reduced systolic blood pressure by 3.1 mmHg. A 2023 Science study demonstrated taurine supplementation extended healthy lifespan by 10-12% in animal models, with cardiovascular aging as a key mechanism.

How It Works

Stabilizes cardiac cell membranes by modulating calcium and potassium channel activity providing anti-arrhythmic effects; acts as an osmolyte maintaining cardiomyocyte volume; conjugates bile acids enhancing cholesterol excretion; antioxidant activity through direct scavenging; modulates the RAAS reducing blood pressure; enhances cardiac contractility through calcium sensitization without increasing oxygen demand.
