After having all of my amalgam fillings removed several months ago, my health began to improve, a lot.
Now, in order to help remove mercury from my body, I take NSP's MSM.

When I started taking it a few weeks after the amalgam removal, I got very sick 4 days after starting and felt almost all the symptoms of mercury toxicity return.

Now, sulphur (MSM) is necessary for the removal of mercury from the body, but I now take 1/2 tablet 3 days a week. Otherwise, I can barely function.

Despite the discomfort, I'm very glad to have the symptoms return when I take MSM. To me, this tells me that it's doing its' job, which is, simply put, to enable cells to expel mercury.

I also take chlorella the same days I take MSM to bond to and help my body eliminate the mercury.

Just thought I'd post this so people can be aware and careful. MSM seems to do a great job, but you may want to spread your cleansing period over a longer period of time.
