How Quercetin supports longevity
When it comes to longevity, Quercetin is one of the most supporting nutrients to consider. Quercetin is a flavonoid found in onions, apples, and berries. A 2020 meta-analysis (9 RCTs, 781 participants) found quercetin supplementation significantly reduced CRP, IL-6, and TNF-alpha, supporting anti-inflammatory effects. May also reduce blood pressure — a 2016 meta-analysis (7 RCTs) showed significant reduction in systolic BP at doses ≥500 mg/day.
What dose to look for
Clinical studies typically use 500–1000 mg of quercetin. RCTs typically use 500–1000 mg/day. Phytosome forms may be effective at lower doses due to enhanced absorption. Supplements that fall short of this threshold are unlikely to match what clinical trials achieved.
Clinical research
Quercetin has moderate clinical evidence for longevity benefits. Meta-analyses of 9+ trials show reduced inflammatory markers and blood pressure at 500+mg/day Learn more
