no need to, i already agree about these: The synthetics DMPS, DMSA, EDTA, etc., are garbage IMO, except in acute poisoning.
also, people do not realize that drug chelation causes you to lose minerals, at least the edta (not familiar with the others). those minerals need replaced.
oral edta chelation is all i recommend for those who don't want to buy a lot of different things, beyond chelation improved and oral chelation by karl loren.
i get most of my C from food, but i have some natrol ester C. i guess it's ok?
