May reduce absorption of some antibiotics — separate by at least 2 hours
Summarized study outcomes with population, design, grade, and effect data.
Meta-analyses show moderate evidence for quercetin's benefits in endurance performance and inflammation reduction, particularly in athletes and older adults. However, the effects are small and further research is needed to fully understand its senolytic properties.
