Formulation Notes

EMIQ 17x Quercetin

Suitable for Vegetarians.

Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.

Enzymatically modified isoquercitrin is a type of quercetin that includes additional glucose molecules for increased solubility and bioavailability. This advanced springtime support product offers quick absorption. Enzymatically modified isoquercitrin was demonstrated to have 17 times greater bioavailability than quercetin itself in one clinical trial. Its core compound, quercetin, was shown in preliminary, in-vitro research to inhibit histamine release. Enzymatically modified isoquercitrin administered at the dose supplied in this product has been clinically demonstrated to maintain eye health during periods of seasonal discomfort.
