Scientists at Friedrich Schiller University Jena (Germany) are working on molecular mechanisms and the benefits of omega-3 fatty acids on blood pressure.
In mice, scientists have found that administering DHA causes blood vessels to widen and therefore lower blood pressure.
On the other hand the kind of DHA often present in food supplements containing omega-3, not only does not bring any antihypertensive effect but especially suppresses and decreases the effect of natural DHA present in the fish. “The unnatural intake of omega-3s can therefore also have counterproductive effects”, specify the authors. In healthy subjects, the intake of these fatty acids such as docosahexaeonic acid (DHA) through the consumption of fatty fish such as herring, salmon and mackerel, should therefore be favored. “
