To be fair there was one positive post - but not by a regular. It looked a bit dodgy - of the form "email me for further details". Just do a search for "magnetic clay" on the list if you are still not convinced and I'm sure you'll find it. Anyway as Cutler says there is no harm in it if you really want to try it.
BTW I've come up with a remarkable way to accelerate the chelation process by 4 months. Its called "don't procrastinate for 4 months".
I'm pretty much ready to start chelation. Just have to measure my caps out.
Hopefully Webmaster will set us up as soon as he checks the suggestions page.
