Origin & tradition
Not traditional: taurine is abundant in animal tissue and is conditionally essential in humans.
Western tradition · Amino acid
Taurine 牛磺酸
An amino acid whose decline was linked to aging in a high-profile 2023 study — with human causality still open.

Data definition. Matched records include all indexed medical endpoints for this intervention — not only longevity. Longevity-relevant records are screened separately and cited in the evidence summary below. Counts are matched-record volumes, not de-duplicated trials and not efficacy claims.
Why longevity buyers care
Key active: Taurine (conditionally essential amino acid).
A 2023 Science study showed taurine declines with age and that supplementation extended healthspan in mice and improved markers in monkeys; whether this translates causally to human longevity is not yet established.
Effect summary
Studied health outcomes
Editorial summary — This table is curated by hand from published research consensus, not automatically calculated from our trial database. Grades reflect our interpretation of the literature. Treat as a starting point, not a definitive verdict. See the Evidence panel below for the underlying trial and paper counts sourced directly from ClinicalTrials.gov and PubMed.
| Health outcome | Effect | Magnitude | Grade |
|---|---|---|---|
| Cardiovascular markers (lipids, blood pressure) | Decreases | Moderate | B |
| Exercise performance / endurance | Increases | Moderate | B |
| Systolic blood pressure | Decreases | Moderate | B |
| Insulin sensitivity | Increases | Minor | C |
| Eye health (retinal taurine levels) | Increases | Minor | C |
Grade: A = robust RCTs · B = several RCTs / meta-analysis · C = limited or mixed RCTs · D = observational or early data
Dosage guidance
How Taurine is typically used
- Typical dose
- 500–3,000 mg/day
- Form
- powder or capsule
- Timing
- any time; pre-workout timing studied for exercise effects
Taurine declines with age in tissues. A 2023 Science paper (Singh et al.) linked taurine deficiency to aging across species. Well-tolerated even at high doses; found naturally in seafood and meat. Vegans tend to have lower levels.
