Taurine Research Guide
Full name: Taurine (2-Aminoethanesulfonic Acid)
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 Taurine 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.
Dosing Protocol
- Typical dose: 1-6 g per day
- Frequency: 1-3x daily
- Duration: Ongoing
- Route: Oral (powder or capsule)
Reported Benefits
- Supports mitochondrial function
- Cardiovascular and blood pressure support
- Exercise endurance
- Antioxidant and anti-inflammatory
- Longevity/healthspan signal
- Calming/GABAergic effects
Potential Side Effects
- Generally very well tolerated
- Mild GI upset at high doses
- Rare loose stools
