Regular is an extremely vague term here, what are you talking about? a few times a year or weekly? Like the other person said, citations needed.

> Regular plasma donation is probably much worse for your long term health than ppb levels of pfas.

You should in the very least read the summary. Even though the trial referred in the submission tracked regular plasma donations, the reduction of "forever chemicals" was not a function of how regular they were, only the volume of blood/plasma donated by the firefighters.

Also, I'd be surprised if the rate wasn't tied to the initial concentration, which would mean that increased rates lead to diminished returns.

Citation?

Does your body not just make more like blood?
