You have to go with what works for you. I tried some prepackaged sets, I also tried cilantro and chlorella, both of them made things intolerable for me. Now I'm on DMSA and ALA and feel good while detoxing. I do have some minor sides, but overall I feel better. Some people can't tolerate the DMSA and ALA, but do well on cilantro and chlorella.

So long as its proven, stick with what works best for you.
