Sauna's are an alternative to DMSA, but not to ALA. I used to be against DMSA because it wasn't natural but changed my mind after enough research and then actually trying it. It only very slightly increases urinary excretion of minerals like Zinc, but has a significant effect on your body's ability to excrete lead and mercury in the urine. It also makes circulating mercury in your blood less likely to react with your cells and damage them since its more attracted to the DMSA....something which a sauna does not do.

Sauna's will not touch brain mercury though. Once mercury vapor, methyl mercury, or ethyl mercury go into the brain and convert to inorganic mercury, its pretty much not coming out without the assistance of something like Alpha Lipoic Acid. Even if your body is completely clean of mercury it won't diffuse out of the brain...it just can't cross the blood brain barrier once in its inorganic form. But of course you have to be free of amalgams for a few months before trying any ALA.
