Interesting. I am using a combination of Liposomal EDTA and oral DMSA. I'm using the EDTA inplace of ALA, since the liposomal form gets into tissures, cells and the brain, but the DMSA, captures any mercury released from the brain or nervous system from the EDTA. It seems to be working fine and I have no retox symptoms. Since the liposomal EDTA remains active for 48 hours, I stop using it 48 hours before I stop the oral DMSA, to avoid redistribution of Hg.
