What it's actually good for

Immunity

Research Supported

Reduces upper respiratory tract infection severity and stabilizes mast cells for allergy relief.

Recovery

Mixed Evidence

May reduce markers of post-exercise inflammation but does not consistently improve performance.

Longevity

Weak Evidence

Studied as a senolytic in combination with dasatinib, but human longevity data is currently limited.

How it works

Quercetin is a plant-derived flavonoid with documented anti-inflammatory and antioxidant properties. Human clinical evidence supports its use for reducing blood pressure and managing seasonal allergy symptoms through mast cell stabilization, though its poor natural bioavailability often requires specialized formulations.

Acts as a natural antihistamine by stabilizing mast cell membranes and inhibits pro-inflammatory cytokines like TNF-alpha and IL-6. It also functions as a potent antioxidant by scavenging reactive oxygen species and chelating metal ions.

Safety

  • Generally well-tolerated up to 1000mg daily for 12 weeks.
  • May cause headaches or tingling sensations at high doses.
  • Caution advised for those with kidney disease or slow COMT/MAOA genetic variants.
