Broadly praised for allergy, sinus, and anti-inflammatory benefits, but notable concern raised about MAOI interactions and variable individual results.
Quercetin 500 by Metagenics delivers 500 mg of quercetin per serving, a bioflavonoid found naturally in fruits and vegetables that supports healthy immune function and may help maintain a balanced inflammatory response. Formulated by a practitioner-grade brand with a focus on clinical-quality inputs, it's well-suited for those seeking a straightforward, meaningful dose of this compound.
Why It's Worth Considering: Metagenics applies rigorous quality standards typical of practitioner-channel manufacturing, and the 500 mg dose aligns with amounts commonly referenced in research contexts.
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.
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.
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.
