A plant flavonoid researched for antioxidant activity and its relationship to normal histamine response.
Quercetin is a flavonoid found across many fruits and vegetables, among the more studied plant compounds for antioxidant activity.
It supports the spray's antioxidant and histamine-response layer alongside Olive Leaf Extract.
Research has examined quercetin's relationship to normal histamine response and general antioxidant support.
This describes general research on Quercetin itself, not the finished BreatheEaseX or CardioEaseX product, which hasn't been the subject of its own clinical trial. See the full ingredients list or the kit overview for more.
