Ok it's lousy, why? That's the part I'm trying to get my head around lol.
because I already know its in a different form But I don't have a clear cut answer on what kind of difference that makes, if at all. Just a resounding maybe/ fish oil is better! But why? or where is it backed up? Every direct comparison in pubmed seems to sound like krill oil marketing.
the marketing from Krill oil claims this
"
The phospholipid binding increases the bioavailability of the omega-3s*
"
and that the ratio of phospholipid EPA/DHA (Krill oil form) to triglycerides EPA/DHA (fish oil form) is 1:5.
But not sure where they derive this. Also the direct studies between krill oil and fish oil seem to have the exact same amounts of krill oil and fish oil (2g-3g total krill/fish oil a day). And the places Krill oil out performed fish oil seem to be all over (more EPA/DHA to the brain, higher serum levels, slightly higher uptake in liver etc... as well as the other stuff in it, choline, Astaxanthin)
but I can only find this review of all the studies to back it up and not much else (granted its like 20 pages of studies some of which are in Pubmed)
Omega-3 DHA and EPA for cognition, behavior, and m... [Altern Med Rev. 2007] - PubMed result second link is to full Review in PDF form

so far what I've got out of everything is
1:1 dosing krill oil vs fish oil (1g of krill oil vs 1g of fish oil) Krill oil outperforms
Krill oil can still have the same contamination issues as fish oil (lesser concentration though)
Krill oil contains antioxidants that stop it form going rancid (the bite your fish oil capsules test)
Krill oil doesn't contain the trans fatty acids that some low quality fish oils can have
all the Krill oil comes form one company, NKO.
at about 1.5g-2g Krill oil (300 combined EPA/DHA per gram) or 2 krill oil pills = max benefit from reviews and studies. Fish oil max benefit from reviews and studies =? 3-4g EPA/DHA per day or 6-7 400/200 fish oil capsules a day.
However at cost effectiveness, Krill oil is 20$-40$ ish ~= a 30-45 day supply (3-4 500mg pills a day or 2 1000mg pills a day).
Fish oil, at a 750mg EPA/DHA pill with added antioxidant (E) a 33ish day supply (180 pills) =~ 20$ (goes as low as 8$ and as high as 40$ depending on brand and what else they claim to have in it)
additional junk per krill vs. fish oil pill (serving size = 2 pills for the following, used NOW products to compare)
