Hey there Nelli,
I am currently using his product. Read my post. After some thought I am thinking about stopping it until clearing my body first of mercury. Like Bex mentioned that chelators that can cross B.B.B. on their way grab mercury from the body and brining it to the brain. HMD has ciliantro and ALA both of which can cross the B.B.B. Therefore, take HMD only after your body is pretty cleared of mercury and the two chelators won't grab much or any mercury on their way to the brain. You can do DMSA, but don't forget that others chelated fine without synthetic chelators. Russ for instance did it with chlorella and protein. Hope this helps. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
