What the study showed, in plain terms

Published in 2018, this source examined exercise and recovery. Design: Published observational athlete supplement registry. Sample/model: 48 amateur triathletes; 23 supplemented and 25 controls. The exposure or intervention was Quercetin Phytosome 250 mg twice daily, expressed as formulation weight. Follow-up or treatment period: 14 days.

Training-run time and self-reported recovery measures improved more in supplemented participants.

No blinded randomized allocation described; training and expectation effects may confound results. The preparation weight is not automatically its quercetin dose.

Key findings

  • Training-run time and self-reported recovery measures improved more in supplemented participants.
  • The recorded outcome domains were Exercise performance or recovery.
  • The exposure was observed rather than assigned as an isolated supplement treatment.

What this study can and cannot tell us

  • No blinded randomized allocation described; training and expectation effects may confound results. The preparation weight is not automatically its quercetin dose.
  • Confounding, dietary patterns, illness, medication use and reverse causation can influence an association. Blood or dietary concentrations do not identify the effect of starting a capsule.
  • Source basis: Source check: PubMed abstract and indexed metadata; full methods were not independently confirmed for this entry. Missing method details, funding information or participant denominators are not inferred.
