What it is
A plant compound found in berries, red wine, and tea. In longevity formulas it is included for its anti-inflammatory and senescence-related lab effects.
Why people take it
In cell and animal studies, myricetin reduces inflammatory signaling and improves metabolic markers. The problem is simple: there are no published human trials testing myricetin alone for any meaningful outcome.
Our verdict
Pure preclinical promise. No human data means no way to verify the dose that would matter.
Structure & class
3,5,7,3',4',5'-hexahydroxyflavone. Inhibits NF-κB, NLRP3 inflammasome activation, and several kinases in vitro; poor oral bioavailability.
Mechanism & clinical data
Semwal et al. and subsequent reviews (Biomed Pharmacother 2021) summarize anti-inflammatory, antidiabetic, and neuroprotective effects across in vitro and rodent models. Bioavailability is low (single-digit percent) and no human RCT with myricetin as monotherapy has been published as of 2026.
Pharmacokinetics
Short; extensive phase II metabolism.
Dose & forms
What to watch out for
Any mg number on a label is a guess — there is no validated human dose. Bioavailability is the weak point.
Where this dose comes from
The trial dose above is our editorial pick from the published human trials for this ingredient. We choose the dose that the best-available studies used on the endpoint most relevant to longevity. The range shows the lowest and highest doses tested in published trials. The landmark studies below are the papers we read to set it. You can click through and check our work.
When new trials publish, our automated sweeps flag them. If a new study materially changes the dose, we update it through editorial review and record the old dose, new dose, and the triggering study in every affected product's recommendation history. The dose is never changed automatically.

EU Court sharpens the bar for botanical health claimsA Court of Justice of the European Union ruling in april 2025 further tightened the requirements for how botanical ingredients (herbs, plant extracts) can be marketed with health claims in the EU, effectively removing much of the flexibility of the on-hold list.

EU report identifies 117 supplement substances as potential health risksThe HoA Working Group on Food Supplements (26 European countries) published its first report evaluating 117 substances used in food supplements. Of these, 65 were assessed as likely novel foods, 6 were already regulated, 34 had insufficient data, and 12 were prioritized for Article 8 restriction under Regulation (EC) No 1925/2006. The 12 priority substances include ashwagandha, curcumin, melatonin, piperine, St. John's wort, coumarin, p-synephrine, maca, holy basil, Melaleuca, black cohosh, and L-tryptophan. The report drew on 1,500 RASFF alerts reviewed between 2017 and mid-2022.

EU Health Claims Regulation adoptedRegulation (EC) No 1924/2006 laid down harmonised rules for nutrition and health claims made on foods, including supplements. Only claims listed in the EU Register of authorised claims can be used. Rejected botanical claims are held in a separate on-hold list.

EU introduces the Novel Food RegulationRegulation (EC) No 258/97 required any food or food ingredient without a history of consumption in the EU before 15 maj 1997 to be authorised before being placed on the market. This is the framework that captures NMN, spermidine as a supplement ingredient, urolithin A, and many other longevity actives.
