Key findings from detailed records
In 24 women aged 55–70, taurine 1.5 g/day for 16 weeks increased the antioxidant enzyme SOD relative to control. This is a human biomarker finding; the study did not measure lifespan or long-term physical function.

OUTCOME-SPECIFIC EVIDENCE
Scientific Evidence Profile
Assessment pending
An outcome-specific assessment has not yet been completed. This is not a finding that the ingredient is ineffective. The study records below remain available.
This profile concerns the stated outcome and population, not the ingredient as a whole. It is not a probability of benefit, a safety rating, a product efficacy rating or an indication of product adoption.
How we assess evidenceIngredient Profile
- What is it?
- Taurine is an amino sulfonic acid. Its sulfur-containing structure distinguishes it from the amino acids used to build proteins. [1]
Sources for this profile
Compound properties and formulation properties are different. These sources do not establish the efficacy of a finished supplement.
- PubChem — Taurine (CID 1123) Chemical identity reference. Maintained by NCBI, U.S. National Library of Medicine. Database record; not a clinical trial.

Read the evidence in context
- Evidence: what was measured in the stated population or experimental model.
- Inference: an interpretation connecting findings; its applicability depends on the study conditions.
- Hypothesis: a proposed explanation or effect that remains to be tested.
Why It Matters #
Do changes in antioxidant markers demonstrate slower human aging? Check the detailed records for study conditions and use the literature map to compare other populations and outcomes.
What Was Studied #
24 women aged 55–70: 13 received taurine and 11 were controls. Randomized, double-blind, placebo-controlled trial. Outcomes: Blood taurine and oxidative stress-related markers[1]
What Was Found #
SOD increased in the taurine group and was higher than the control group after intervention. Not all oxidative stress markers improved.[1]
What the Evidence Means #
Small sample of women only. Lifespan, disease incidence and long-term functional maintenance were not directly assessed.[1]
Comparing similar populations, formulations, durations and outcomes helps identify where findings agree and where they differ.
What We Can Learn #
Even if a title says “antiaging,” check what was measured. These findings do not demonstrate extended human lifespan.
What Remains Unknown #
Further questions include reproducibility across populations and formulations, and the long-term balance of benefits and harms. Use the literature map as a starting point for these questions.

A literature map covering different populations, outcomes and formulations. Read alongside detailed records to avoid treating one trial as the conclusion for an entire ingredient.
Selected: 2026-09-21. Bibliographic information checked against Europe PMC / PubMed. Editorial selection considered major papers and a range of populations and questions. This is not a systematic search covering all recent research.
