Quercetin

Quercetin has been shown to be one of the most useful and physiologically active flavonoids.* Quercetin helps support stable mast cells to promote inflammatory balance.. This potent bioflavonoid can be used for maintaining or supporting the proper levels of enzymes and physiologic factors necessary for normal respiratory and sinus health, to help support seasonal respiratory challenges.*

Take 2 capsules twice per day between meals, or as directed by your healthcare professional.

Recommendations:

Take zinc with quercitin for better absorption.  Also take ascorbic acid to stabilize the quercitin. 

Warning: If pregnant, consult your physician before taking.
