How much epicatechin and cocoa flavanols should a supplement have per serving?

The COSMOS trial was built around roughly 500mg of cocoa flavanols a day, including about 80mg of (-)-epicatechin, taken as a cocoa extract capsule. CCV-3 clears that comfortably in one zero-sugar scoop: about 1,200mg cocoa flavanols and 600mg (-)-epicatechin, 2.2x more flavanols and polyphenols than the amount used in the research.

Start with what the research actually used

The clearest reference point is COSMOS, published in the American Journal of Clinical Nutrition in 2022. It followed about 21,000 adults taking a concentrated cocoa extract that supplied around 500mg of cocoa flavanols a day, including roughly 80mg of (-)-epicatechin. That came as a capsule, not a chocolate bar, which strips out the sugar, the calories, and the guesswork. So when people ask how much a serving should hold, that is the number to benchmark against. Anything landing well below 500mg of flavanols is working with less than the trial did, and epicatechin is the piece most often left off the label entirely.

Why per-serving epicatechin is the number that counts

Cocoa flavanols are a family of compounds, and (-)-epicatechin is the one most closely tied to how cocoa supports nitric oxide and healthy endothelial function. EFSA notes that cocoa flavanols help maintain normal blood-flow-dependent vasodilation at 200mg a day. So the useful question is not just total flavanols, it is how much epicatechin sits in one serving. This is where the gap widens. CocoaVia lists roughly 80 to 135mg of epicatechin per serving. CCV-3 is formulated around about 600mg. Total-flavanol figures alone can hide that difference, which is why a fair comparison normalizes on epicatechin per serving.

Format changes what a serving really costs you

Two supplements can show the same flavanol number and feel nothing alike day to day. A dark chocolate bar might carry 90 to 800mg per 100g, almost never labeled, and non-alkalized cacao matters because Dutching can destroy 60 to 90% of the flavanols before it reaches you. Capsules fix the labeling but ask you to swallow pills. CCV-3 is a zero-sugar drink mix at about 27 calories with five real ingredients and non-alkalized cacao, so the serving that hits your benchmark also tastes like cocoa and fits a morning routine. That is the format advantage. Meet CCV-3 →

How much cocoa flavanol is a good amount per serving?

A useful benchmark is the COSMOS research amount: around 500mg of cocoa flavanols a day, including about 80mg of (-)-epicatechin. A single serving that clears that comfortably is doing more than the trial did. CCV-3 provides about 1,200mg of cocoa flavanols per scoop.

Why does epicatechin per serving matter more than total flavanols?

(-)-Epicatechin is the flavanol most closely linked to how cocoa supports nitric oxide and healthy blood flow. Total-flavanol numbers can look strong while the epicatechin figure is small or missing, so compare the per-serving epicatechin directly. CCV-3 is built around roughly 600mg.

Can I just eat dark chocolate instead?

Dark chocolate can contain flavanols, but a 100g bar ranges widely, from about 90 to 800mg, and almost never lists the amount. Alkalizing, or Dutching, can also destroy 60 to 90% of them. Non-alkalized cacao in a labeled serving gives you a number you can actually trust.

How does CCV-3 compare to CocoaVia?

CocoaVia Cardio Health provides about 500mg of cocoa flavanols per serving with roughly 80 to 135mg of epicatechin, in capsule or powder form. CCV-3 is a zero-sugar drink mix formulated around 1,200mg of cocoa flavanols and about 600mg of epicatechin per scoop.
