2/ Second step, chelate first with DMSA only, to get your body burden of Mercury down.
3. Third step, add in ala into your chelation once you have chelated with DMSA for several months or so
ala can cross the blood-brain barrier, and it will move mercury to the place of lower concentration. So if your body has high mercury and your brain has low, ala will bring mercury into the brain.
so if you chelate for awhile with DMSA, you can drop the level of mercury in the body, and then when you add in ala you are doing it safely.
Maybe, you are clear about this, and sorry if you are but I just wanted to make sure.
