Feature Summary
Quercetin, a dietary flavonol known to be one of the most significant plant-derived antioxidants,has multiple biological actions, with preclinical studies showing that it helps clear cellular debris naturally produced by the body and supports healthy cardiovascular and respiratory function.*1
The limiting factor in quercetin’s supportive function appears to be its poor bioavailability. Enzymatically modified isoquercitrin (EMIQ) is a mixture of quercetin monoglucoside and its alpha-oligoglucosides that has been shown to have significantly greater bioavailability than other available forms. In animals, EMIQ was shown to produce a 40-fold increase in C(max) (peak plasma concentration) and an 18-fold increase in the area under the curve compared to quercetin.2 In humans, EMIQ supplementation increased plasma concentrations to a significantly greater degree than other forms, including the aglycone and isoquercitrin (Q3G) forms.3
Quercetin helps maintain histamine levels already within the normal range.*10 Studies have shown EMIQ to be considerably more bioavailable than regular quercetin. Two trials found that EMIQ may help with seasonal support of upper respiratory health and outdoor nose and eye health.*11,12 In a recent crossover trial, EMIQ was found to support healthy endothelial function and helped maintain healthy cardiovascular function.*13 Healthy American football players supplementing with whey protein had greater gains in lower limb muscle mass and antioxidant protection when consuming 42 mg EMIQ per day compared to whey alone.*14
