Optimized Quercetin by Life Extension delivers quercetin in a phytosome form, bound to sunflower lecithin phospholipids, to support enhanced absorption compared to standard quercetin powder. This flavonoid, naturally found in fruits and vegetables, is commonly taken to support healthy inflammatory response and antioxidant activity. It's well-suited for adults looking to reinforce immune and cardiovascular wellness as part of a broader health routine.
Why It's Worth Considering: The phytosome delivery system addresses quercetin's notoriously low oral bioavailability, making this formulation a more practical choice than conventional quercetin supplements at equivalent doses.

More category questions
Does quercetin help with allergies?
Yes. Quercetin stabilizes mast cells, preventing them from releasing histamine in response to allergens. Clinical studies show 500-1000mg/day reduces allergy symptoms (sneezing, itching, congestion) comparably to some antihistamine drugs. Start 2-4 weeks before allergy season for preventive benefit.
How much quercetin should I take?
For allergies: 500mg 2x/day starting 2-4 weeks before allergy season. For immune support: 500-1000mg/day. For longevity/senolytic effect: 500mg with dasatinib (under practitioner guidance). Standard quercetin has low bioavailability — choose quercetin phytosome or EMIQ (enzymatically modified isoquercitrin) for 20x better absorption.
Is quercetin a senolytic?
Yes — quercetin is one of the most studied senolytic compounds (agents that clear senescent 'zombie' cells). In combination with dasatinib, it's been shown to reduce senescent cell burden in human trials. As a standalone supplement at 500-1000mg/day, it has milder senolytic activity but still contributes to healthy aging through reduced inflammation and oxidative stress.
