Quercetin Dihydrate

Quercetin dihydrate is a naturally occurring flavonoid, a type of plant pigment found in many fruits, vegetables, and grains. It is often extracted from plant sources like onions or apples and then processed into a more stable, hydrated form for use in supplements and foods.

Quercetin dihydrate is primarily used as a dietary supplement due to its antioxidant properties. It is sometimes added to beverages like sports drinks and teas, as well as other food products, to potentially enhance their health profile.

Quercetin is generally recognized as safe (GRAS) by the FDA for use as a dietary ingredient. It is known for its antioxidant effects, which may help protect cells from damage. International bodies like JECFA and EFSA have evaluated quercetin, but did not set specific numerical limits. Research into its health benefits is ongoing, with some studies suggesting positive effects on inflammation and heart health, while others show mixed results.
