While there are many established quercetin benefits and even more alleged quercetin benefits, one I had not considered was quercetin’s possible ability to help individuals tap their energy reserves. This new quercetin benefit is implied by a recent study conducted by the Arnold School of Public Health (University of South Carolina) and partly funded by the United States Department of Defense. This study was published in the International Journal of Sports Nutrition and Exercise Metabolism in 2009.
The study, which involved healthy but untrained adult men and women (college students), measured subjects fatigue capacity on stationary bikes and their VO2max. VO2max, which was completely new to me upon reading this study, measures an individual’s maximum oxygen capacity.

In this Interstitial Cystitis Quercetin article, I’ll discuss known and possible Quercetin Side-Effects. I’ll include quercetin side-effects related to interstitial cystitis, but I’ll cover overall quercetin side effects as well.
If you research quercetin side-effects, you’ll soon find that no clear toxicity exists. So taking large amounts won’t immediately have any obvious ill effects. However, there is some theoretical and anecdotal evidence that consuming large amounts of quercetin regularly — especially with other anti-oxidants (especially Vitamin C) — can potentially manifest some problems in some people despite quercetin benefits.
As is the case with many anti-oxidants — especially bioflavonoids such as quercetin — taking too many anti-oxidants at once can result in a pro-oxidant effect. What this means is that the inflammation-reducing effects of supplements such as vitamin c and quercetin can actually instead cause inflammation if you take them both in very high doses.
Anecdotal evidence suggests that this manifests itself most commonly in joint discomfort after prolonged usage of quercetin.
