I have been doing low dose chelation since the end of December. My hair analysis showed no mercury as did a urine challenge test. There is a theory that you can still have heavy metal issues based on disordered minerals in hair analysis. The logic is that they are poor excretors. Reading up on a number of people's experiences with low level Hg poisoning + my mum having worked a bit with Hg and me being first born + amalgam fillings + hair analysis, I decided to give chelation a go after reading up on the Andy Cutler protocol which was easy enough & cheap to do. Basically low dose alpha lipoic acid with some low dose DMSA plus with a few other supps to help with the elimination out via urine/stools (With Hg most of it comes out in feces). When I first started I was encouraged as I had a bit of a pick up in cognition, dreams and libido. You do 3 days on then have a break between rounds. Well with each round my skin is getting worse. At first I developed a small slight rash on side of nose, but it disappeared, but with each round it seemed to be staying on longer and spreading more over my face. I can feel my skin is raised slightly like a rash, and from a distance it looks like I have been out in the sun all day. I read up on the www and I did not find too many complaining of this side effect of chelation. There were a few though who took ALA as part of general health/anti aging strategy that complained of hives and dropped it. They were on 600mg a day. I guess I was taking approx the same amount spread out during the day (every 3 hrs). I have no idea if this is an allergic reaction or a consequence of mercury being shifted around. Mercury poisoning does cause skin rashes & dermatitis. Around the time when I was in my teens and I started to get fillings my skin deteriorated and was reddish on my face. Has anyone else experienced this taking ALA? I still think low dose Hg chelation is a good thing for me, but I dont want my face getting worse each round as I am at the point were I feel self-conscious with how I look now. I am doing coffee enemas + chlorophyll + red clay + drinking more water and recently sarsparilla tea. .
