Quercetin is among the most abundant natural flavonoids, and it is found in high concentrations in plants such as onions, apples, berries, red wine, broccoli, capers, pomegranate and Ginkgo biloba. The Quercetin used in Gaia Herbs formulations comes from Dimorphandra mollis tree, which is native to the tropical savannah ecoregion of Brazil. It has been studied for its support of the body's occasional, normal histamine response.*

What is Quercetin Used for?

Quercetin is combined with Turmeric in synergistic formulations that support cardiovascular health, joint health and the respiratory system to promote the bioavailability of Curcumins, the active constituents in Turmeric.* In research supported by Gaia, Quercetin and Curcumins, as well as Resveratrol and Black Pepper, were found to be better absorbed together than individually.
