Natural Factors Bioactive Quercetin EMIQ - Quercetin provides antioxidant protection and helps control allergy symptoms. It also supports healthy blood pressure and heart health. EMIQ is manufactured through natural enzymatic process that attaches glucose chains (glycosides) to the quercetin molecule. The result of this modification is that the quercetin is provided in a water-soluble form thereby greatly enhancing its bioavailability. In the digestive process the glycoside portion is cleaved, liberating the quercetin, and as a result EMIQ greatly increases quercetin levels in the blood compared to the ingestion of quercetin or its related compound Rutin. Blood levels of quercetin are more than 40 times greater with EMIQ compared to an equal amount of quercetin.
