That would have to be grass fed for best results. it's the ALA (short chain omega 3) in the greens that get converted to DHA/EPA so grain fed won't have a lot of omega 3. You can observe this difference in the butter from grass fed versus grain fed: thd grass fed derived butter melts at lower temperatures because of the higher omega 3. However you can also take algea or algea derived omega 3 supplements, i think the species is called nannochloropsis gaditana, and it has vegan omega 3, so probably causes no issues with fish allergies.
