Ive been taking DMSA, 100 mg every 4 hours for 2 days a week, and then taking a break for the rest of the time. It has been documented in numerous cases of DMSA reestablishing glutathione levels, and as a person who is glutathione supplement intolerant, I thought I would like to hear what the experts think. Dmsa is being used with autistic kids with much success as a chelator of heavy metals, lead, mercury, tin, and even binds to uranium (yes uranium is coming out of autistic kids, look it up). I couldnt tolerate alpha lipoic acid in larger than 100mg per day, NAC more than 600mg, or very much straight glutathione. DMSA is making my exercise tolerance increase, and reducing my rosacea by 75% in 2 weeks...but I do have flares on my "on dmsa" days. I also make sure to dose up on methylation agents on my off days.
