Taurine for Parasympathetic Activation
Taurine has plausible autonomic and blood-pressure effects but almost no HRV-specific human data.
Overview
Verdict
How It Works
Dosing & Protocol
Typical dose
- Recommended dose
- 1-3g/day
- Expected timeframe
- 4-8 weeks
Protocol
- form
- Taurine powder or capsules
- duration
- Not applicable - no autonomic endpoint has been assessed
- co factor
- Evidence is insufficient. Taurine is an agonist at GABA-A and glycine receptors, which is a plausible route to reduced sympathetic drive, and animal studies show taurine in the brainstem modulates blood pressure and sympathetic outflow, with central administration lowering pressure. A meta-analysis found taurine reduces blood pressure by about 3 mmHg systolic in humans, which is consistent with some autonomic effect but does not demonstrate it. No human trial has measured heart rate variability, baroreflex sensitivity or any other index of parasympathetic activity after taurine supplementation.
- titration
- Not applicable
- starting dose
- Not established for this outcome. Trials used 1-6 g/day for other endpoints
Evidence
What the studies say
No studies are yet linked to both Taurine and Parasympathetic Activation.
Safety
Caveats
Well tolerated but unproven for this purpose. Prioritise breathing practice and sleep first.
