Is Quercetin Exercise Performance Randomized Trial safe?

The current Migaku evidence database contains 2 reusable source documents for Quercetin Exercise Performance Randomized Trial. This answer focuses on safety, limits, and clinician-discussion contexts. - The overall percentage of studies reporting an improved exercise performance following flavonoid supplementation was 37%, the proportion being 25% when considering quercetin, 28% for flavanol-enriched extracts, and 54% for anthocyanins-enriched extracts. [Ruiz-Iglesias P (2021); evidence level 1] - From the studies reporting an enhanced performance, only two, using anthocyanin supplements, focused on the immune system and found certain anti-inflammatory effects of these flavonoids. [Ruiz-Iglesias P (2021); evidence level 1] - Flavonoids are attracting increasing attention due to their antioxidant, cardioprotective, and immunomodulatory properties. [Ruiz-Iglesias P (2021); evidence level 1] - Nevertheless, little is known about their role in exercise performance in association with immune function. [Ruiz-Iglesias P (2021); evidence level 1] - Results A sustained reduction in relative limb blood supply (P Conclusion These data suggest that quercetin does not improve exercise performance, physical activity or limb blood supply in mice with sustained hind-limb ischaemia, and therefore is unlikely be an effective treatment for PAD. [Phie J (2021); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
