What is Quercetin?

Quercetin is a plant flavonoid found abundantly in onions, apples, berries, and capers. It's one of the most studied flavonoids, with wide-ranging health benefits including anti-inflammatory, antioxidant, and immune-modulating effects.

Anti-Inflammatory Action

Quercetin inhibits inflammatory enzymes and cytokines, reducing inflammation at the cellular level. This makes it useful for conditions involving chronic inflammation.

Immune Support

Quercetin modulates immune responses and has antiviral properties. It became popular during recent times for its potential to support respiratory health and zinc absorption into cells.

Allergy Relief

Quercetin stabilizes mast cells, reducing histamine release. This makes it a natural option for managing seasonal allergies without the drowsiness of antihistamines.

Absorption Enhancement

Quercetin alone is poorly absorbed. Look for formulations with enhanced bioavailability, such as quercetin phytosome, quercetin combined with bromelain, or liposomal forms.
