What it is
A sulfur-containing amino acid your body makes and that's abundant in meat and shellfish. Blood levels drop with age. A 2023 Nature paper caused a stir by showing taurine supplementation extended lifespan in mice and monkeys.
Why people take it
Yadav et al. 2023 (Science) showed 3 to 6 g/kg body weight (huge doses) extended mouse lifespan ~10% and improved multiple aging markers. Human data limited to biomarker studies. Human dose extrapolation is uncertain.
Our verdict
Interesting but early. If you take it, 3 to 6 g/day (not the marketing 500 mg) is closer to what mouse studies suggest, scaled down.
Structure & class
2-aminoethanesulfonic acid. Non-proteinogenic amino sulfonic acid.
Mechanism & clinical data
Yadav et al. 2023 (Science) demonstrated ~10% lifespan extension in mice at 1 g/kg. Human interventions on aging biomarkers ongoing. Rodent-to-human dose translation controversial.
Pharmacokinetics
~1 hour.
Dose & forms
What to watch out for
Very cheap in powder form; capsules charge a premium for the same molecule.

Where this dose comes from
The trial dose above is our editorial pick from the published human trials for this ingredient. We choose the dose that the best-available studies used on the endpoint most relevant to longevity. The range shows the lowest and highest doses tested in published trials. The landmark studies below are the papers we read to set it. You can click through and check our work.
When new trials publish, our automated sweeps flag them. If a new study materially changes the dose, we update it through editorial review and record the old dose, new dose, and the triggering study in every affected product's recommendation history. The dose is never changed automatically.

EU Court sharpens the bar for botanical health claimsA Court of Justice of the European Union ruling in april 2025 further tightened the requirements for how botanical ingredients (herbs, plant extracts) can be marketed with health claims in the EU, effectively removing much of the flexibility of the on-hold list.

EU report identifies 117 supplement substances as potential health risksThe HoA Working Group on Food Supplements (26 European countries) published its first report evaluating 117 substances used in food supplements. Of these, 65 were assessed as likely novel foods, 6 were already regulated, 34 had insufficient data, and 12 were prioritized for Article 8 restriction under Regulation (EC) No 1925/2006. The 12 priority substances include ashwagandha, curcumin, melatonin, piperine, St. John's wort, coumarin, p-synephrine, maca, holy basil, Melaleuca, black cohosh, and L-tryptophan. The report drew on 1,500 RASFF alerts reviewed between 2017 and mid-2022.

EFSA confirms taurine in energy drinks is not a safety concernEFSA's ANS Panel published a scientific opinion confirming that taurine as an ingredient in energy drinks is not of safety concern at current intake levels. The NOAEL was established at 1,000 mg/kg body weight/day. The opinion resolved outstanding concerns raised by the EU Scientific Committee on Food in 2003 about potential harmful effects of taurine on the brain.

EU Health Claims Regulation adoptedRegulation (EC) No 1924/2006 laid down harmonised rules for nutrition and health claims made on foods, including supplements. Only claims listed in the EU Register of authorised claims can be used. Rejected botanical claims are held in a separate on-hold list.

EU introduces the Novel Food RegulationRegulation (EC) No 258/97 required any food or food ingredient without a history of consumption in the EU before 15 maj 1997 to be authorised before being placed on the market. This is the framework that captures NMN, spermidine as a supplement ingredient, urolithin A, and many other longevity actives.
Taurine is an amino acid that supports heart muscle function and glucose metabolism, but its 2023 aging-biomarker claim did not hold up.
Verified 2026-08-06. We update this section as new peer-reviewed trials land.
Best-supported claim
Taurine's best-supported human effects are on cardiometabolic markers and heart failure symptoms. A 2025 metaanalys of 34 RCTs found taurine significantly reduced fasting blood glucose, HbA1c, fasting insulin, HOMA-IR, triglycerides, and total cholesterol, with the strongest glucose and lipid effects at 1.5-3.0 g/day for 8 or more weeks (https://academic.oup.com/nutritionreviews/advance-article/doi/10.1093/nutrit/nuaf220/8340615). A separate 2024 metaanalys of 20 RCTs and 808 participants found taurine reduced heart rate, systolic and diastolic blood pressure, and NYHA heart failure functional class, while increasing left ventricular ejection fraction, with the largest benefits in heart failure patients specifically (https://pmc.ncbi.nlm.nih.gov/articles/PMC11325608/). For exercise, a metaanalys found oral taurine produced a small but real improvement in endurance performance (Hedges' g=0.40) regardless of whether it was taken as a single 1 g dose or 6 g/day for 2 weeks.
Not supported by the evidence base
Taurine was propelled into the longevity supplement conversation by a 2023 Science paper (Singh et al.) reporting taurine declines with age across species and that supplementation extended mouse lifespan by 10-12%, with only correlational human data. A rigorous 2025 follow-up in the same journal, using longitudinal data from three distinct human cohorts plus nonhuman primates and mice, directly contradicted the premise: circulating taurine increased or stayed unchanged with age in healthy individuals, and there was no clear association between taurine levels and health status (https://www.science.org/doi/10.1126/science.adl2116). The 2025 paper concluded that individual variability in taurine levels is generally larger than any change across the lifespan, meaning taurine is unlikely to be a useful aging biomarker, let alone a proven anti-aging intervention in humans. No completed human RCT has tested whether taurine supplementation extends lifespan or slows biological aging; a German trial (TauAge) testing 4 g/day for 6 months on biological age markers was still recruiting as of its registration.
Typical dose
500 mg to 3 g/day, with cardiometabolic benefits concentrated at 1.5-3 g/day taken for 8 weeks or longer
Säkerhet
Taurine has a strong safety record across the dozens of RCTs reviewed, including in heart failure patients receiving standard medical treatment. The 2024 metabolic syndrome metaanalys found no significant difference in adverse effect rates between taurine and control groups (odds ratio 1.48, not significant) (https://pubmed.ncbi.nlm.nih.gov/38755142/). Doses used in trials range from 0.5 to 6 g/day without safety signals. Long-term safety data beyond one year in the general population remains limited.
