TBH I had to look up Wolfe, I'm not really into the paleo movement. But I remember John Berardi saying he took (and advised to take) something like 3 softgels per meal, with 3 meal per day IIRC. That dosage, using the run-of-the-mill 180/120 softgel, is probably over 3g/d of Omega 3, assuming the softgel doesn't only contain EPA and DHA but also ALA.(edit: BTW I've been losing confidence in the soundness of Berardi's advice over time due to some things like the issue we're discussing and others like this one)
Kresser said in a comment:
the 1g/d refers roughly to the total amount of polyunsaturated omega-3s. So it depends how much of the 1200 mg capsule is omega-3, not just EPA & DHA
The other "nutritionally significant" Omega 3 being ALA according to Wikipedia. It is implied there are other Omega 3 but they might not be of interest for our discussion (and actually, I've never read anywhere about something other than EPA DHA and ALA)
When I was researching Omega 3 supplements, I realized most only advertise the EPA and DHA content, only a minority either state ALA content, "other Omega 3s" or "Total Omega 3" amount (on a sidenote I found this interesting because some brands appear to have no ALA in their gels)
With Kresser recommending to stay under 1 g/d, that means for some brand even 3 softgels per day may be too much.
