What the study showed, in plain terms

Published in 2006, this source examined exercise and recovery. Design: Randomized double-blind crossover cycling study. Sample/model: 11 elite male cyclists. The exposure or intervention was Antioxidant vitamin formulation with quercetin versus the formulation without quercetin. Follow-up or treatment period: 6 weeks.

The quercetin-containing formulation improved cycling time relative to baseline.

The abstract emphasizes a baseline comparison rather than a clear direct between-formulation effect. Small sample and multiple ingredients limit attribution.

Key findings

  • The quercetin-containing formulation improved cycling time relative to baseline.
  • The recorded outcome domains were Exercise performance or recovery.
  • The result applies to the tested exposure: Antioxidant vitamin formulation with quercetin versus the formulation without quercetin; 6 weeks.

What this study can and cannot tell us

  • The abstract emphasizes a baseline comparison rather than a clear direct between-formulation effect. Small sample and multiple ingredients limit attribution.
  • An individual controlled trial must be interpreted alongside its comparator, sample size, endpoint selection and independent replication. It does not validate a different commercial formulation or a general longevity claim.
  • 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.
