Search "high flavanol cocoa powder" and you get a wall of brands shouting percentages, multipliers, and words like "supercharged." Almost none of them tell you the one number that matters: how many milligrams of cocoa flavanols are in one serving. So we pulled the number from each brand's own labels, listings, and lab statements and lined them up.
The number to compare: milligrams per serving
Flavanols are the family of compounds in cacao (epicatechin, catechin, and their chains, the procyanidins) that most of the research is built on. Two dose benchmarks come up again and again:
- 200 mg per day is the level behind the European Food Safety Authority's authorized claim that cocoa flavanols "help maintain endothelium-dependent vasodilation, which contributes to normal blood flow."
- 500 mg per day is what the COSMOS trial used in 21,442 adults over a median 3.6 years. Its primary endpoint (total cardiovascular events) was not statistically significant; the secondary finding of 27% fewer cardiovascular deaths is why the number gets quoted so much.
So when a brand says "10x more flavanols than regular cocoa," the real question is: 10x of what, and does it get you to 200 or 500 mg in a serving you would actually drink?
Brand comparison (stated flavanols per serving)
| Product | Stated flavanols per serving | What it is | Notes |
|---|---|---|---|
| Actual Superfoods High-Flavanol Cacao | 500 mg cocoa flavanols (printed on the label) | Un-Dutched whole cacao powder plus lion's mane, ashwagandha, maca, Ceylon cinnamon | Per-batch heavy metal results published on our lab results page. No sugar, no fillers, no proprietary blend. |
| CocoaVia Cardio Health Powder | 500 mg cocoa flavanols | Cocoa extract (Cocoapro), the ingredient used in COSMOS | Extract in a flavored powder, roughly 30 mg caffeine per serving. The most direct "COSMOS dose" product. |
| Cocoa Dynamics (Santa Barbara Chocolate) | 400+ mg per 5 g tablespoon | Single-ingredient natural cocoa powder | States 7.5% to 14.6% flavanols by weight, lab verified. Straight cocoa, nothing added. |
| Black Forest "Supercharged" Cocoa Flavanols | Advertises 1,200 mg "flavanols and flavonoids"; its own product page splits that into 600 mg flavanols plus 600 mg flavonoids | Concentrated cocoa extract | Read the label carefully: "flavanols" and "flavonoids" are not the same thing, and adding them together inflates the headline number. |
| MAÏA Super Cacao | Lists 180 mg epicatechin per serving on its Amazon listing; total flavanol figure varies by listing | Cacao with added nattokinase, magnesium, and a "flavonoids blend" | Epicatechin is one flavanol, not the total. Ask for the full flavanol number before comparing. |
| Regular natural (non-alkalized) cocoa powder | About 170 mg per tablespoon | Grocery baking cocoa | Based on the Miller 2008 average of 34.6 mg flavanols per gram of natural cocoa. Cheap and real, but you need about 3 tablespoons to reach 500 mg. |
| Dutch-processed cocoa powder | About 20 mg per tablespoon | Grocery "cocoa processed with alkali" | Heavily alkalized cocoa averages 3.9 mg flavanols per gram. Great for brownies, nearly useless for flavanols. |
For context, when ConsumerLab tested cocoa powders it found anywhere from 10 mg to 676 mg of flavanols in a 5 gram serving. The label "cocoa" tells you almost nothing about the flavanol content. The processing does.
Five things to check before you buy
- Is the number "flavanols," "flavonoids," or "epicatechin"? Flavonoids is a broad category that includes flavanols plus a lot of other compounds. Epicatechin is one flavanol. A total cocoa flavanol number is the only apples-to-apples figure.
- Is it printed on the label, or only in the marketing? A label claim is a regulated claim. A web page is not.
- Whole cacao or extract? Extracts (CocoaVia, Black Forest) deliver the dose in a small scoop. Whole cacao delivers it as a real drink with fiber, minerals, and the flavor of actual chocolate. Neither is wrong; they are different products.
- Is it Dutched? Any ingredient list that says "processed with alkali" has lost most of its flavanols. We wrote a whole post on what Dutch processing does to flavanols.
- Can you see the heavy metal results? Cocoa is a known source of lead and cadmium. A brand that tests every batch and shows you the numbers is taking on a cost most brands skip. Ours are here.
Where we land
If you want the COSMOS dose in a pill or a tiny scoop, CocoaVia is the honest choice. If you want straight cocoa powder with real numbers, Cocoa Dynamics is a good one. If you want the 500 mg dose as a drink you actually look forward to, made from un-Dutched cacao with the milligrams printed on the tin and the lab results public, that is exactly why we built Actual Superfoods High-Flavanol Cacao.
