Scared of DMPS

Is it possible to completely chelate mercury with natural supplements only? I've read so many warnings about DMPS such as it can leach nutrients from the body causing side effects. I'm sure my body is chronically deficient in certain nutrients because of the health problems I've had related to mercury toxicity for over a decade. So I'm really concerned about using a product that could cause harm, even though I'm DESPERATE to rid my body of heavy metals because I want my health back asap.

Any thoughts? Thanks.
