Phenolic acids, a class of phytochemicals found abundantly in plant-based foods such as fruits, vegetables, coffee, and whole grains, have garnered interest for their potential cardiovascular benefits. The scientific rationale for their use in supporting or treating cardiovascular disease (CVD) is based on several mechanisms, primarily their antioxidant, anti-inflammatory, and vasodilatory properties. Experimental and observational studies have shown that phenolic acids, such as ferulic acid, caffeic acid, and gallic acid, can reduce oxidative stress and inhibit low-density lipoprotein (LDL) oxidation—a key step in the development of atherosclerosis. Moreover, some clinical trials and meta-analyses suggest that diets high in phenolic acid-rich foods are associated with improved endothelial function, lower blood pressure, and reduced risk of cardiovascular events.

However, while laboratory and animal studies provide compelling mechanistic data, and epidemiological studies are suggestive, direct evidence from large, randomized controlled trials in humans is still limited. Most clinical trials to date have used whole foods or extracts rich in phenolic acids rather than isolated compounds, making it difficult to attribute effects solely to phenolic acids. Therefore, while there is a scientific basis and moderate evidence supporting the cardiovascular benefits of phenolic acids, more targeted research is needed to confirm their efficacy and optimal dosage in cardiovascular disease prevention and treatment.
