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.
Reported Benefits (Provisional)
Origin & History
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.
Research Narrative (Provisional)
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
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
- Rich in flavonoids, particularly myricetin. - Contains phenolic compounds that contribute to antioxidant activity. - Low in calories and free from fats.
Reported Mechanism (Provisional)
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 Narrative (Provisional)
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.
