"But most importantly is its preference for inorganic mercury over other metals. If you have high metals beyond mercury it might takes months of DMSA before the mercury starts coming out. We've all seen people using DMSA for years without results."

Mercury toxicity clogs the natural detoxification channels for other heavy metals as well, so even with very tiny exposure to other heavy metals over years in addition to the mercury, it is likely enough that people who are sick from amalgam fillings have also developed toxicity from other heavy metals as well.

"I don't see why you are so opposed to DMPS when plenty of people are having great results with it and even Cutler recommends it."

My concerns with DMPS are toxicity, that it is not easily available, and also that it is so expensive. If DMSA wasn't available, or I couldn't tolerate DMSA, then I guess I might not be so against DMPS, although I might just chelate with ALA alone and if that didn't work then I might consider DMPS. I guess if I don't see any major improvement in my condition using DMSA and ALA I might eventually decide that DMPS might be worth the risk and expense. I think so far I have only done around 50 rounds of DMSA and ALA, and probably less than 20 of those rounds were using 200 mg ALA with at least 50 mg DMSA. Now I am chelating with 100 mg DMSA and 200 mg ALA per dose, but only with 3 day rounds. I think I need to do many more rounds with DMSA plus ALA. I had so many amalgams for so many years, so I don't expect this to clear up so quickly.
