I'm no expert, but my guess is that this could be true, because selenium is one of the factors that helps remove silver from the body, and people who use colloidal silver are recommended to supplement with selenium. In helping to remove the silver from the body, the selenium most likely gets used up itself to some degree, more than if you were not using CS.
I take 200 micrograms (mcg) of selenium a day, and have since I started using CS.

Can anyone here comment on this please? MA "I caution anyone using the Colloidal silver for an extended period of time. It depletes the body of selenium. I have personaly used it on my lyme disease gelding, and this was how I found it out. I now do NOT give Especial any CS at all. "
