DPA is the key product in producing higher prostaglandin that keeps the artery walls soft and free of plaque: found to work at a higher, more effective level than EPA. Drawn from seal oil, this omega 3 is more easily absorbed into the human body than fish oil, and is in higher concentrations than in fish oil. Seal oil is also virtually free of cholesterol.

Omega 3 decreases plasma lipids through reduced synthesis of fatty acids and very low-density lipoproteins. They also have a direct effect on the heart muscle, increase blood flow, decrease arrhythmias, improve arterial compliance, decrease the size of the infarct and reduce several cellular processes that compromise heart function. It has also been suggested that marine oils may retard atherosclerosis through their effects on platelet function, platelet-endothelial interactions and inflammatory response.
