Overview

Life Extension Bio-Quercetin provides 250mg of quercetin in a phytosome complex that delivers 15x better bioavailability than standard quercetin supplements. Standard quercetin has notoriously poor absorption (less than 2% bioavailability), making the phytosome technology critical for therapeutic benefit. Quercetin is a potent flavonoid antioxidant with anti-inflammatory, antihistamine, and senolytic (clearing senescent cells) properties. Research shows quercetin supports immune function, reduces allergy symptoms, and may slow cellular aging.
