DHA in phospholipid form is more bioavailable and enters the brain via the MFSD2A transporter, which is particularly relevant for individuals with the APOE4 allele.

“DHA, specifically, in phospholipid form, it's more bioavailable. So, if you're comparing exact quantity or concentration in triglyceride form versus phospholipid form, you will get more in your plasma cells, in your plasma, plasma cell, in your plasma with krill oil. However, krill oil supplements are so low dose. I mean, good luck getting two grams of omega-3 from krill oil. And also, krill oil supplements are notoriously rancid. I don't know for whatever reason. - Maybe that's what made me itchy all over. - I think they're just... I haven't found a good krill oil supplement. I pretty much stay away from it. I mean, if you smell it too, I mean, it just smells rancid. So, but the thing is, and I also published a paper on this back in 2019, yeah, something like that, about DHA in phospholipid form getting into the brain through a different mechanism than DHA in triglyceride form. And so it's going through a transporter called the MFSD2A transporter. And I think it's very relevant for people with an APOE4 allele, so-”
