Well, if in doubt dont. Personally I think you are better off at this point supporting your body by diet (candida diet with plenty of proteins and healthy fats, excluding sugar, grains (especially gluten), fruit and milk) and taking supportive supplements, rather than getting into stuff to chelate. Yes, some people get away with it but I wouldn't do it.

The most I would take with amalgams still in would be a homeopathic detox kit that simply aids and encourages the organs to eliminate toxins and metals (like Heels homeopathic detox kit). I would do that, plus diet, plus supplements like vitamin C, vitamin E, vitamin A, B complex, magnesium/calcium, zinc, and a green food supplement like Nature's way Chlorophyll.

But aside from that? I would not be brave enough to muck around with much else. The supplements there by the way are recommended commonly for most people. Not only on candida forums, but also a biochemist (andy Cutler), and also another health professional.

Again if you do not react well to something, stop it. You will know what works for you. But with the diet? symptoms can get worse due to the body beginning to unload toxins and heal.

You may react well to sulfur foods/supplents like garlic, onions etc, but you may not. Sulfur can really stir up mercury and cause issues, so go easy on it if you try it. I'm no professional and can only pass on what I have read and tried for myself and what I have found is helpful rather than risky.

Everybody is different and even the best professional is not going to get it right in all cases. You are the best monitor of your own symptoms.
