Minerals to chelate fluoride?

It would be nice to have some kind of mineral supplement which will safely chelate the evil fluoride out of the body and prevent any kind of adverse affects of fluoride.

I am still not able to avoid fluoride in water. its there, I know the dangers and I am drinking it. I know that Distillation and Reverse Osmosis are 2 methods to remove fluoride from water. But for some reason both these methods dont appeal to me. Distillation is slow, consumes tons of electricity and RO is wastage of water. Plus both Distilled Water and RO water are demineralized.

I drink BRITA filtered water which removes some contaminants but not all.

I am wondering if supplements like Magnesium/Boron should be able to safely chelate all the bad fluoride out of the body via the kidneys...

PS:

I am completely avoiding fluoride toothpaste for the past 8 months or so. I am using plain baking soda for my teeth burshing. Recent visit to dentist showed that my teeth are in excellent shape. No problemo.
