Can Cowden be used for heavy metals?

Hi everyone my sister did the Cowden protocol a few years ago and was very happy with it. I however have titanium rods along my spine and am concerned that because I have heavy metal issues doing the protocol will be a waste of money since I have heard that heavy metal holds on to biofilm making it very hard to kill any bacteria or virus. I’m at a loss on what to do! I have been sick for years. What do you all recommend for a combination of heavy metal and Lyme. Thank you
