  • With Quercetin, Ginkgo, and Synephrine.
  • Stops the release of histamines.
  • Promotes a healthy immune system.
Aller-Response™ is a seasonal formula featuring quercetin. Human cell culture studies with quercetin demonstrated its capability to inhibit the release of histamines. Ginkgolide B, in human cell culture studies, was found to be a potent inhibitor of platelet-activating factor, a substance that stimulates the release of histamine from immune cells. Vitamin A and vitamin C, along with the mineral zinc, help support the immune system.
Suggested Use: Up to 3 tablets daily between meals. For best results, take 2 tablets in the morning and 1 in the afternoon.
