silicon is not a metal, and does not appear to have any adverse health effects. it may have some benefits for bone & teeth, but that's kind of iffy, still. and, it seems to potentially flush out the aluminum, without harming the iron.
great.
i need to look into this a bit more. but, i could potentially add a dash of silicon to my water and coffee to try to flush me out.
will that also help remove mercury and lead, or just aluminum?
