Regarding heavy metal chelation, so far I only know there are several options:
1. Cutler protocol, using DMSA & ALA
2. DMPS, with DMSA/EDTA etc. (it really depends which heavy metal you have in your body)
3. Chlorella & Cilantro
So far I know there are people who recovered from each of options above. So far the conclusion I can draw is that it's all depend on your condition. What is important is that you can work with knowledgeable doctor who can access your whole condition properly and be able to do the right chelation protocol for you. The 3 options I mentioned above has its own pluses and minuses, and the good thing is to find right doctor who can diagnose properly for you (and not grossly applying the only method he knows for you, regardless of your condition.)The problem with chelation if you are not looking thoroughly, you might as well turn the toxin around in your body and thus makes the condition worsen. Honestly, if I can't find the right doctor who I am comfortable to work with, I will not embark on any chelation protocol by my own.
