Feature summary

Enzymatically modified isoquercitrin (EMIQ) is a highly bioavailable form of quercetin – a flavonoid that exerts significant anti-allergy effects. 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.

EMIQ has been found to be safe in many toxicity studies and has been self-affirmed as Generally Recognized as Safe (GRAS) for use in specific foods in the US and as an antioxidant. Natural Factors Bioactive Quercetin EMIQ contains no GMOs, artificial colours, preservatives or sweeteners, fish, shellfish or animal products, and is suitable for vegetarians/vegans.

How it works

EMIQ can be viewed as a precursor molecule to quercetin – a flavonoid that has demonstrated a wide range of beneficial effects in preclinical studies, especially in regards to anti-allergy properties. Unfortunately, until now quercetin has not shown much clinical effect because of poor absorption. By increasing the quercetin content in the blood and throughout the body, EMIQ produces significant benefits particularly as it relates to antioxidant protection and anti-allergy effects.

In addition to its antioxidant effects, EMIQ exerts anti-allergenic properties by reducing the formation of allergic mediators such as histamine as well as stabilizing membranes of mast cells to block the release of histamine and other allergic/inflammatory compounds. As a result of this action on mast cells, EMIQ helps control allergy symptoms.

EMIQ may also offer benefits in protecting against cardiovascular disease via a number of mechanisms. In addition to antioxidant properties, EMIQ increases the formation of nitric oxide (NO) by the cells that line the blood vessels. NO formation is associated with improved blood flow and blood pressure control.

The primary applications of EMIQ at present are in promoting health in individuals suffering from allergies, but it may also show benefit in people experiencing increased oxidative stress such as those with high blood pressure.
