I don't think we know what EPA / DHA ratio is optimal. It's common for it to be 2:1 EPA:DHA in pills. We know the brain and eyes use DHA for a lot of things, but I think the brain uses EPA for other things. Plus, the body converts some EPA to DHA.
We also don't know what the upper limits are for tolerating Omega-3, but they're high, because we are all so out of whack on our Omega-6 to Omega-3 ratio.
