first of all I want to say that here is also a chelation forum and a cutler chelation forum. There are people who know more about this stuff.
The Chlorella/Cilantro is safe to take while You have fillings I think, but make sure by asking in those forums.
Cilantro should not be taken too early, because it mobilizes mercury in the brain.
Vitamin C is good for heavy metals, but also great while You do a parasite
I do the Dr. Wilson protocol. http://www.drlwilson.com
First You do a hair test, then they give You a program with diet, supplements etc.
It works by replacing the toxic metals with good metals.
The body just stores those toxic metals, because it is depleted of good metals, such as calcium, magnesium, zinc, selenium etc.
