The Short Answer
Myricetin is a flavonol polyphenol that acts as a potent antioxidant by donating electrons to neutralize free radicals and chelating metal ions. It modulates multiple cellular pathways including NF-κB, MAPK, and Nrf2 to provide anti-inflammatory and neuroprotective effects.

Health Benefits
Acts as a potent antioxidant, neutralizing free radicals and reducing oxidative stress by 50%. - Reduces inflammation by inhibiting pro-inflammatory pathways, alleviating chronic pain. - Supports brain health by enhancing synaptic plasticity, improving cognitive function. - Promotes cardiovascular health by reducing LDL cholesterol levels, supporting heart function. - Enhances liver health by promoting detoxification processes, reducing toxin accumulation. - Supports skin health by protecting against UV-induced damage, maintaining youthful appearance. - Aids in cancer prevention by inducing apoptosis in cancer cells, reducing tumor growth.
Origin & History
Natural habitat
Myricetin is a naturally occurring flavonoid found in various fruits, vegetables, and herbs such as berries, onions, and tea. It is typically extracted through solvent extraction methods from plant sources.
“Traditionally used in herbal medicine for its health-promoting properties, myricetin has been a component of diets rich in fruits and vegetables historically associated with longevity.”Traditional Medicine
Scientific Research
Several in vitro and animal studies have demonstrated myricetin's antioxidant and anti-inflammatory properties. Human studies are limited but promising in cardiovascular and neuroprotective effects.
Preparation & Dosage
Traditional preparation
Typical dosage ranges from 100-500 mg per day. Consult a healthcare provider before use.
Nutritional Profile
- Rich in flavonoids, particularly myricetin. - Contains phenolic compounds that contribute to antioxidant activity. - Low in calories and free from fats.
How It Works
Mechanism of Action
Myricetin exerts its effects by inhibiting the NF-κB signaling pathway, reducing production of pro-inflammatory cytokines like TNF-α and IL-6. It activates the Nrf2 transcription factor, upregulating antioxidant enzymes including glutathione peroxidase and superoxide dismutase. The compound also modulates MAPK pathways and inhibits phosphodiesterase enzymes, affecting cyclic nucleotide signaling.
Clinical Evidence
Limited human studies exist for myricetin, with most research conducted in cell culture and animal models. Preclinical studies show significant antioxidant activity with 50% reduction in oxidative stress markers and improved cognitive function in rodent models. Small human pilot studies suggest cardiovascular benefits, but larger randomized controlled trials are needed. Current evidence is promising but preliminary, requiring more robust clinical validation.
Safety & Interactions
Myricetin is generally well-tolerated with few reported adverse effects at typical dietary intake levels. It may interact with anticoagulant medications due to its potential blood-thinning properties. High doses could theoretically interfere with iron absorption due to its metal-chelating properties. Pregnancy and breastfeeding safety has not been established, so supplemental doses should be avoided during these periods.

Frequently Asked Questions
What foods contain myricetin naturally?
Myricetin is found in high concentrations in berries (particularly blueberries and cranberries), red wine, tea, onions, and walnuts. Berries typically contain 50-200mg per 100g serving, making them the richest dietary sources.
How much myricetin should I take daily?
No official recommended dosage exists for myricetin supplements. Most studies use doses ranging from 100-500mg daily, while typical dietary intake is 1-2mg per day. Start with lower doses and consult a healthcare provider before supplementing.
Can myricetin help with diabetes?
Preliminary studies suggest myricetin may help regulate blood sugar by inhibiting alpha-glucosidase enzymes and improving insulin sensitivity. However, human clinical trials are limited, and it should not replace standard diabetes medications without medical supervision.
Does myricetin cross the blood-brain barrier?
Yes, myricetin can cross the blood-brain barrier, though in limited amounts. Studies show it reaches brain tissue where it may protect neurons from oxidative damage and support synaptic plasticity, contributing to its potential cognitive benefits.
Is myricetin better absorbed with food?
Myricetin absorption is enhanced when taken with meals containing fats, as it is a lipophilic compound. Taking it with quercetin or vitamin C may also improve bioavailability by protecting it from degradation in the digestive system.
Does myricetin interact with blood pressure or cholesterol medications?
Myricetin may have mild interactions with statins and antihypertensive drugs due to its ability to lower LDL cholesterol and support cardiovascular function, potentially enhancing their effects. It is advisable to consult with a healthcare provider before combining myricetin supplements with prescription medications for heart health or blood pressure management. Most dietary sources of myricetin pose minimal interaction risk, but concentrated supplements warrant medical oversight.
Is myricetin safe for pregnant or nursing women?
There is insufficient clinical evidence to confirm myricetin safety during pregnancy and lactation, and it should generally be avoided unless specifically recommended by a healthcare provider. While myricetin is naturally present in foods, concentrated supplement forms have not been adequately studied in pregnant or nursing populations. Pregnant women should prioritize obtaining myricetin through whole food sources rather than supplementation.
What does research show about myricetin's effects on inflammation and joint health?
Clinical studies demonstrate that myricetin inhibits pro-inflammatory cytokines and NF-κB signaling pathways, making it promising for managing chronic inflammatory conditions and pain. Multiple in vitro and animal studies suggest benefits for joint health and arthritis-related inflammation, though human clinical trials remain limited. Current evidence supports myricetin as a complementary approach to inflammation management, but more large-scale human studies are needed to establish definitive efficacy.
