Mercury is in a lot of "stuff" we ingest and use. Mercury is in vaccines for starters and that is why I avoid them, unless emergency, but for a strong immune system I do my work to keep mine strong.

Mercury is in our mouths from amalagms and I know people do remove them but I have never and just live what has bee done.

And there could be traces of mercury in tap waters so I buy all my water and best quality I can afford.

I had a mineral panel done many yrs ago and mercury came in the highest in the toxic area.
