Mechanism of Action
Cocoa flavanols act mainly on the endothelium, the thin layer of cells lining the inside of blood vessels. Their active compound, epicatechin, supports the production of nitric oxide, a signalling molecule the endothelium releases to regulate the tone of the vessel wall.
This production tends to decline with age. By supporting it, flavanols contribute to maintaining the elasticity of blood vessels.
Flavanols belong to the polyphenols, a family of plant compounds found in many fruits and plants. Their absorption occurs in the small intestine and depends heavily on how much the source cocoa has been processed.
Key Benefits
- Strong
Blood vessels that stay supple: cocoa flavanols help maintain the elasticity of blood vessels, which contributes to normal blood flow; this effect is obtained with a daily intake of 200 mg.
- Moderate
Slightly lower blood pressure: a systematic review of 35 randomised trials measures a small reduction in adults consuming cocoa products rich in flavanols, with the effect more pronounced in people whose pressure is already elevated.
- Emerging
A cardiovascular signal at large scale: the largest randomised trial on cocoa flavanols, conducted in over 21,000 adults over 3.6 years, confirmed their good tolerability and observed lower cardiovascular mortality in the supplemented group, though the primary endpoint was not met.
Dosage & Forms
Cocoa flavanols are measured in milligrams of total flavanols, of which epicatechin is the reference fraction. Dietary cocoa contains highly variable amounts: roasting and alkalisation, a process that softens cocoa's taste, destroy a large share. An ordinary dark chocolate bar therefore provides only an inconsistent fraction.
The formula uses a standardised extract delivering 200 mg of flavanols per day. This dose matches the documented intake for maintaining vascular elasticity and the range of the main clinical trials (200 to 500 mg per day). Standardisation ensures a stable content in every batch, a condition for any serious calibration.
In the Singular Formula
Inclusion rationale
Native polyphenols of the cocoa bean (Theobroma cacao), flavanols are among the best-documented plant compounds for vascular function, led by epicatechin. Industrial cocoa processing (roasting, alkalisation) destroys most of this fraction, which is why a standardised extract is preferred over ordinary cocoa. Cocoa flavanols help maintain the elasticity of blood vessels, which contributes to normal blood flow; this effect is obtained with a daily intake of 200 mg, the dose used in the formula. The largest randomised trial conducted on these compounds, in over 21,000 adults, clarified their place in a cardiovascular longevity approach. In the formula, cocoa flavanols extend the vascular axis alongside omega-3 (EPA+DHA) and black garlic.
Selected form
Cocoa (Theobroma cacao) extract standardised for flavanols, the bean's native polyphenols, of which epicatechin is the most studied. The extraction process preserves the flavanol fraction that industrial cocoa processing (roasting, alkalisation) largely degrades. Standardisation ensures a consistent flavanol content in every batch, where dietary cocoa varies widely. Powder raw material, no excipient. Quality: vegan, non-GMO.
Formula dosage
0 to 200 mg.

Safety & Precautions
Cocoa flavanols have a favourable safety profile at nutritional doses. The standardised extract contains theobromine, an alkaloid naturally present in cocoa, in small amounts at the dose used. People sensitive to methylxanthines, such as theobromine and caffeine, may prefer taking it earlier in the day.
Supplementation is not recommended during pregnancy and breastfeeding as a precaution, due to insufficient data. Cocoa has been consumed by humans for centuries, providing a substantial track record of use. No significant drug interactions are documented at these doses.

Effect of cocoa flavanol supplementation for the prevention of cardiovascular disease events: the COSMOS randomized clinical trial Randomised trial in 21,442 adults receiving 500 mg of cocoa flavanols per day or placebo for 3.6 years. The primary endpoint (total cardiovascular events) was not met; cardiovascular mortality, a secondary endpoint, was lower in the supplemented group. | ||||
