detoxing metals

One thing I'm not hearing about is that there is not much metnioned from the NB program on how to gently detox heavey metals.
Is this so mething that just happens naturally witht he NB? or have some of you just incorporated by your own research or with a naturopath, on what to take?

ANd, this would include the most gentleest of detoxing.
What have some of you tried that you've had good results with?
Thanks Paulette
