Here is what I've learned:

-You really shouldn't use Cilantro or Chlorella if you still have amalgams in as these mobilize mercury.
-DMSA is dangerous as it also binds to your good minerals such as magnesium and zinc.
-Cilantro is a good mobilizer, but needs binding agent to move out of the body.
-Cilantro crosses the blood brain barrier ( alpha lipoic acid does also-mercury is stored in the brain)
-Chlorella does cross the BBB
-chlorella is an agressive mobilizer, but I think it has a weak bond as well.
-garlic will inactivate cilantro
-don't use vitamin C simultaneously with cilantro or selenium
-selenium binds to mercury

I took chlorella at first, but later realized that once you have a total dental revision done, your body automatically starts to dump the stored mercury so I was feelihg bad because I was having too much detoxing (re-intoxification) going on. For now I am taking mercury detox (by Tyler which contains seleium ,amino acids, mg), glutithione (which is needed for detoxing), and algin (binds but doesn't mobilize)
