I know for sure that you have to wait with zinc supplementation until all the dmps is out of your body because dmps can not keep mercury and zinc apart. So if you take zinc while you chelate you defeat all your efforts. I get dmps once a month as an injection ($100). If I don't get the dmps injecton I take dmsa tablets for 3 days in a row 3 times 500 mg. Somtimes I skip a month to give my body rest. Dmsa is much cheaper, you can order it from Thorne it is on their webpage, that is the best company says my doc and my pharmacist as well.
I guess I read every book out there about getting mercury out of your body but I have not heard of msm and wheypoder does not work for me because I have developed lactose intolerance. I also read that the candida thrives on merucry and that it is not possible to get rid of it as long as there is lots of mercury in your intestines that's where the chlorella comes in. It will suck up the mercury that gets into your intestines.
Enemas are a great help tp relieve your intestines fron the mercury too. If you can afford it get a hydro colon on the night you chelate and your liver will thank you. By the way I am not a doctor , so my advice is just from my experience
