Can’t speak for the grandparent poster, but I’ve heard/read enough casual claims of “donating plasma reduces microplastic load in the blood” that it’s been somewhere in the far back of my mind to research further. I already donate blood regularly and would immediately hop on the plasma train if these sorts of claims panned out.

Particularly since I have extended family members who have seen great results from a round of apheresis treatment to reduce their LDL. And apparently some long covid sufferers have also found relief from this type of “blood cleansing” treatment.
