here's another thing that's confusing about cutler's procotole.

Why does he reccommend to introduce ala once the BLOOD levels are down, and not once the BODY level are down? (which is different). The way I see it, you might have blood mercury very low but body mercury still high and once you introduce ala it is true you shouldn't put more mercury into the brain as there is no excess in the blood, but the ala is not selective as andy says, so it might pick up mercury somewhere from the body and then drop it in the brain as the round ends. Sure you should not increase brain mercury (amount) but you might not get it lower through redistribution, which is as bad as more brain mercury burden because of new damage.

It's analogical to taking ala with amalgams in the mouth. You maybe months away after the last exposure, but can't use ala due to the presence of 'source', which might put more mercury into the brain. High body burden is the same type of "source" from the brain chelation perspective.

So it is my opinion one should introduce ala once the body mercury is down so that once ala gets the brain mercury out, it gets it out permanently and not back again from the body.
