I’ve previously written about the question whether krill oil is, in fact, as the proper Latin name of the small critters it is made of, i.e. Euphausia superba, would suggest “superba”, ahh… I mean better than fish oil when it comes to its effects plasma and organ DHA and EPA.
A large number of previous trials – almost all short-term, by the way – verify the commonly held belief that the largely (35-65%) phospholipid-bound krill oil (KO) has a bioavailability advantage over the exclusively triglyceride-bound fish oil (FO) Di Marzo 2010; Konagai 2013; Ramprasath 2013).
The latter, that’s at least what previous trials suggested seems to be most pronounced in the brain, where DHA and EPA play an important role for structural integrity and function of neuronal membranes, act as powerful anti-inflammatory agents, and keep the brain functioning properly while we age.
Now, a new study from the Korea University in Seoul shows: The brain thing isn’t even right and tracking the EPA+DHA levels for weeks clearly suggests that there is no practically relevant advantage with krill vs. fish oil.
