Flavanols, a group of bioactive compounds found abundantly in cocoa, tea, apples, and certain berries, have been investigated for their cardiovascular benefits. Scientific research over the past two decades has shown that dietary flavanols can support vascular health, primarily through improving endothelial function, enhancing nitric oxide bioavailability, and reducing blood pressure. Randomized controlled trials and meta-analyses suggest that regular consumption of flavanol-rich foods or extracts leads to modest improvements in flow-mediated dilation (FMD), a marker of vascular function, and may contribute to lower blood pressure in both healthy individuals and those at risk for cardiovascular disease.

While flavanols are not a treatment for "heart weakness" (a non-specific term that could refer to heart failure or reduced cardiac output), their vascular benefits may indirectly support overall cardiovascular health. The European Food Safety Authority (EFSA) has approved a health claim stating that cocoa flavanols help maintain the elasticity of blood vessels, which is relevant to heart function. However, there is limited direct evidence for their use in treating established heart failure or directly strengthening the heart muscle. Most evidence supports their role in prevention and maintenance of vascular function rather than as a standalone therapy for significant cardiac weakness.

Overall, the evidence for flavanols supporting cardiovascular health is moderate, particularly in the context of endothelial function and blood pressure. More research is needed to establish their effect on specific cardiac conditions such as heart failure.
