Iodine and heavy metals

I was just wondering to what extent the Iodine protocol detoxifies heavy metals like lead and mercury. From what I've read pretty much the only way to get heavy metals out of the body is a continious chelation protocol like Andy Cutlers.

I do believe however that the Iodine protocol heals the body to an extent that it is more effective at getting rid of heavy metals, but I was just wondering whether eventually I'll have to start andy cutler's protocol again once im settled into the Iodine plus supportive supplement protocol.
