I don't believe that zeolite particles are small enough to pass through the blood brain barrier. In fact I don't believe they can even get into the blood. But feel free to show evidence that they can.
I would review the posted research to see if they discuss minute details of the mechanism. Lots of data showing effectiveness using hair sample element testing. But you are correct that presence of neurotoxins in hair samples (and reduction over time) is not definitive that they are coming OUT of the brain specifically.
