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.

Be careful if: pregnant, breastfeeding

Upper limit: 3 g — per day for healthy adults — Observed Safe Level from a published risk assessment of human clinical trial data (Shao & Hathcock 2008); higher intakes have been tested without adverse effects but the authors judged those data insufficient for a confident long-term conclusion. This is a risk-assessment reference, not a regulatory upper level. The legacy note attributed the 3 g/day figure to EFSA; the EFSA (2009) opinion concluded taurine exposure from regular energy-drink consumption is not of safety concern but does not state this figure.

    How much is too much

    3 g — per day for healthy adults — Observed Safe Level from a published risk assessment of human clinical trial data (Shao & Hathcock 2008); higher intakes have been tested without adverse effects but the authors judged those data insufficient for a confident long-term conclusion. This is a risk-assessment reference, not a regulatory upper level.

    What this means: Bars count reported findings, not treatment effectiveness or certainty.

    One study may report several findings or appear in more than one pairing. Counts do not show the size of an effect. Comparable numerical estimates are not established for this summary.

    Suggested uses (unproven)

    Where people report using it and what trials suggest

    • Moderate evidenceBlood-pressure reduction (small RCTs, 1.5-6 g)
    • Weak evidenceExercise-metabolism markers

    Where the evidence is negative

    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.

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

    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”, “Possible harm” or “Unclear”). It is a study result — not advice, and not a promise it will work for you.
    Evidence
    Study design describes how research was conducted. It is not a formal certainty assessment.
    Effect size
    The result recorded in this summary. “Not reported” means the value is missing from the summary; it does not establish that the publication omitted it.

    Reported direction, numerical results and study design are separate. Certainty has not been formally graded in this table.
