Myricetin

A flavonol found in berries, walnuts and tea, studied for glucose control and antioxidant effects. The entire evidence base is preclinical; no human trial of myricetin supplementation has been published.

Evidence last reviewed: August 2026

What the science says

Glucose and metabolic effects Limited evidence
A 2025 review of myricetin's pharmacology describes antidiabetic, antioxidant and anti-inflammatory activity across cell and rodent studies, including improved insulin sensitivity in diabetic animal models. No randomized human trial has tested these outcomes.
Anti-inflammatory effects in arthritis Limited evidence
An experimental arthritis study in rodents reported that myricetin reduced inflammatory signalling and oxidative stress markers. Animal arthritis models frequently fail to predict human results.

Dosage & safety

Studied doseNo human dose established. Supplements commonly supply 50–200 mg/day as a label dose. Bioavailability of oral myricetin is poor and it is rapidly conjugated.

SafetyNo human safety trials. Myricetin inhibits several CYP450 enzymes in vitro and has shown pro-oxidant behaviour at high concentrations, so interaction with medication is a theoretical concern. Avoid in pregnancy, breastfeeding, and alongside anticoagulants without medical advice.
