flavonoid
3 interactions related to flavonoid
vitamin c + quercetin
Quercetin is a flavonoid with antioxidant, anti-inflammatory, and antiviral activity; vitamin C 'recycles' oxidized quercetin back to its active form, prolonging its effect and preventing prooxidant byproducts. The combination has been studied for immune support and antiviral effects.
fisetin + quercetin
Fisetin and quercetin are structurally related flavonols with overlapping but distinct senolytic and anti-inflammatory mechanisms. Fisetin was identified in a Mayo Clinic screen as the most potent natural senolytic, while quercetin has been clinically tested as part of the dasatinib + quercetin senolytic combination, and the two together broaden the senolytic and antioxidant coverage.
quercetin + bromelain
Bromelain is a proteolytic enzyme complex from pineapple that improves quercetin absorption (reportedly 2-3x) and adds independent anti-inflammatory effects (fibrinolytic activity, COX modulation, bradykinin reduction). The pair is commonly co-formulated for inflammation, allergy, and immune support.
