The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
so plasma levels are lower numbers they correlate pretty well by and large with red cells but red cells are much more stable long-term marker of omega-3 status than plasma so I like the red cell test for that purpose so that's pretty much what we use in our research studies is red cell
I think measuring blood omega-3 levels are really important and whether it's the test we do with the omega-3 index which is red cell epa DHA or a plasma test or a plasma phospholipid test or a whole blood test whatever i just think we need to see more doctors measuring omega-3 status
