Taurine (Taurine (2-Aminoethanesulfonic Acid))

Category: Anti-Aging. Status: OTC supplement.

A conditionally essential amino acid concentrated in muscle, brain, heart, and blood cells. Circulating taurine declines with age, and a landmark 2023 study showed taurine supplementation extended healthspan and lifespan in multiple species, making it a core longevity supplement for biohackers.

How it works

Acts as a cytoprotective osmolyte and antioxidant, stabilizes mitochondrial function, modulates calcium signaling and GABA-A/glycine receptors, reduces inflammation, and supports bile acid conjugation. Taurine deficiency accelerates cellular senescence markers.

Key facts

  • Molecular weight: 125.15 Da
  • Half-life: ~1 hour (plasma)
  • Bioavailability: ~90-100% oral
  • Storage: Room temperature, keep dry.

Dosing overview

  • Typical dose: 1-6 g per day
  • Frequency: 1-3x daily
  • Duration: Ongoing
  • Route: Oral (powder or capsule)

Protocol notes

  • Longevity users commonly take 2-3 g/day, split or as a single dose.
  • Pre-workout use is popular at 1-2 g for endurance and cardiovascular support.
  • Powder mixes easily in water; capsules are convenient but require several to reach gram doses.

Reported benefits

  • Supports mitochondrial function
  • Cardiovascular and blood pressure support
  • Exercise endurance
  • Antioxidant and anti-inflammatory
  • Longevity/healthspan signal
  • Calming/GABAergic effects

Possible side effects

  • Generally very well tolerated
  • Mild GI upset at high doses
  • Rare loose stools

Research

  • Taurine deficiency as a driver of aging (2023): Taurine supplementation increased healthy lifespan by ~10-12% in mice and improved multiple aging biomarkers across species.
  • Taurine and cardiovascular health (2021): Supplementation lowered blood pressure and improved endothelial function in hypertensive subjects.

Community reviews of Taurine

Rated 5 out of 5 from 4 community reviews by ResearchSafe members.

  • peptide_path_pam rated it 5/5 - Noticed clear benefits within weeks: Added Taurine to my protocol about 6 weeks ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
  • titrate_tina rated it 5/5 - Worth adding to the protocol: Taurine has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
  • fasted_frank rated it 5/5 - Genuinely effective after 2 weeks: Been using Taurine for about 2 weeks and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
