Chelation is just an aggressive way of detoxing heavy metals. It's not the only way. First, correcting any digestive issues will take a major burden off other organs to allow them to do their job properly. I did a few months of Spirulina after the Amalgam removal. If down the road I suspect I still have dangerous levels of mercury, then I'll look into it but there's nothing in my head telling me it's a problem anymore. My health has improved greatly so if it was a bad case of mercury poisoning I would probably know it.
In my opinion there's too many risks involved with flushing or detoxing too fast...I like slow and progressive improvement leading to longterm cure. I've learned to be patient with healing
