Null overall in 3 large trials; plausible only if your diet is low in flavanols.
Skip unless your diet is genuinely low in flavanols (little tea, berries, apple, cocoa). Then 500 mg/day is a reasonable bet. Choose products with lot-level cadmium/lead testing.
Cocoa flavanols (Cocoa extract flavanols (epicatechin-rich)) is a polyphenol / cognitive with evidence grade C, meaning it is backed by mixed or small human trials. We track 1 products containing Cocoa flavanols. Typical doses range from 500 to 500 mg per serving. The top-ranked product scores 5.5 out of 10 on our composite scale (dose, evidence, price, testing, transparency). Prices range up to $48.99 per month.

Flavanol-rich cocoa extract at 500 mg/day including about 80 mg epicatechin. Not equivalent to cocoa powder or chocolate, which vary in processing and heavy metals.
All three COSMOS cognition substudies found no overall benefit. COSMOS-Web showed memory improvement in the lowest diet-quality/flavanol subgroup, tracking a urinary flavanol biomarker - a depletion-repletion pattern, not a universal effect.

(-)-Epicatechin-rich cocoa flavanol extract; raises endothelial nitric-oxide signaling and cerebral perfusion, supporting hippocampal plasticity when habitual intake is low.
COSMOS-Mind global cognition null (0.03 SD, p=0.28; PMID 36102337). COSMOS-Clinic null (PMID 38070683). COSMOS-Web prespecified low-flavanol subgroup improved (PMID 37252983). Earlier COSMOS-Web analysis found diet-quality moderation (PMID 33589674).
Epicatechin metabolites peak within 2 hours; effects on flow-mediated dilation same day.
Cocoa products accumulate cadmium and lead; buy lot-tested products only. About 25 mg caffeine per 500 mg serving. Residual theobromine can affect migraine-sensitive users.
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.

We track 1 products containing Cocoa flavanols. The top-ranked product scores 5.5 out of 10 on our composite scale, which evaluates dose, evidence, price, third-party testing, and transparency. See the comparison table above. Scores are editorial judgments, not a scientific standard.
Cocoa flavanols has evidence grade C, meaning it is backed by mixed or small human trials. Grade A means replicated human RCTs with hard endpoints. Grade B means human RCTs with biomarker outcomes. Grade C means mixed or small human trials. See our evidence grading methodology.
Evidence grades are reviewed when new human RCTs are published. Product counts update automatically as new products are added. Dose ranges reflect published trial data, not brand recommendations. Read how we verify.
