It could be a flare up of yeast issues. Chelating can cause that, plus ALA apparently can contribute to yeast problems and so does DMSA, but DMPS not as much.

But again, detox symptoms also. Toxins are being moved around and some of them are coming out, so it is very hard not to get symptoms as they come loose and circulate around your body and in the process yeast unfortunately can certainly flare, yet at the sametime you're probably detoxing too.

So white tongue can mean candida, but often it can be toxins coming out. In fact, some people who are on a candida diet and improving, feel worsetemporarily and often get a coated tongue during that time.
