I do not think that you should be much concerned about this, because other studies show that more DHA than EPA is preferable when using other criteria.

So the conclusion is that nobody knows for sure if you should eat more DHA than EPA, to have a better brain, or less DHA than EPA, to have a better heart.

What is certain is that you need some minimum quantity of both DHA and EPA.

Especially for children, who do not have yet to worry about cardio-vascular problems, a supplement with more DHA than EPA seems actually a good choice.
