High DHA fish oil supplementation improves postprandial arterial stiffness and endothelial function, potentially reducing cardiovascular disease risk, whereas EPA alone may not provide the same postprandial benefit.

To support vascular health and reduce arterial stiffness after meals, choose a high DHA fish oil supplement (where DHA is higher than EPA). This may improve how your arteries handle the stress of a fatty meal. Standard fish oils with higher EPA may not offer this specific post-meal vascular benefit.

McManus et al. (2016) reported that a single dose of DHA, but not EPA, significantly improved postprandial arterial stiffness compared to the control, as assessed by augmentation index, which, if sustained, would be associated with a significant decrease in CVD risk. Armah et al. (2008) found that postprandial triacylglycerol-rich lipoproteins, isolated after a high DHA fish oil meal, increased endothelial nitric oxide synthase and decreased nicotinamide adenine dinucleotide phosphate (NADPH) oxidase gene expression compared to the control meal.
