Taurine

Also known as 2-aminoethanesulfonic acid

Sulphonic beta-amino acid abundant in cardiac and skeletal muscle and the central nervous system; involved in bile acid conjugation, osmoregulation, and modulation of GABA/glycine receptors, and studied for cardiovascular and exercise performance.

Common claims the trials do not support

The 2023 'taurine slows ageing' Nature paper was in mice/monkeys — no human evidence of lifespan effect.
Energy-drink harms come from caffeine/sugar, not taurine, but taurine does not neutralise them either.

Conditionally essential amino sulfonic acid; epidemiology links it to ageing, human endpoint trials absent.

Safety notes: Very well tolerated up to 3 g/day per EFSA; higher doses lack long-term data.

Evidence grades reflect study quality and consistency, not marketing claims.

What trials found, in numbers

Summaries of published trial results for this compound, grouped by condition. Numbers are reported exactly as the researchers published them — we never calculate or convert.

How to read this table

Benefit: What the trial saw happen: whether the measured outcome moved in the helpful direction in that one study (the tag on each row: “Benefit seen”, “No clear benefit” or “Unclear”). It is a study result — not advice, and not a promise it will work for you.
Evidence: How strong the research behind that result is. A meta-analysis pools many studies (strongest); a systematic review collates them; an RCT tests against a control (placebo); observational studies only watch — they can suggest, not prove.
Effect size: How large the measured change was, exactly as the researchers published it. “No number reported” means the abstract gave no effect size — we never invent one.

In short: benefit is what was observed; evidence is how much you should trust the observation. A “Benefit seen” tag on a weak study counts for far less than the same tag on a meta-analysis.
