im concerned about taking any type of chelator with the fillings still in. years ago i wanted to do a mercury detox and started taking chlorella and eating a lot of cilantro. shortly after i began to get weird headaches that were associated with certain types of foods. i have had this ever since and attribute it to mercury mobilization. I would say build up your immune system, strengthen you liver, thyroid and adrenals. Take NAC to boost glutathione levels so when you do detoz your body will be strong. hope this helps
