This is some of the info re why taking Selenium may be beneficial.I was 
convinced to go for the Selenomethionine form as recommended in the posting 
from Steve Norton.

A couple of comments.
 
There are several ways that silver is excreted from the body depending
on the form the silver is in:
 
1) Small silver particles are filtered by the kidney.
2) Larger silver particles are removed by Kupffer cells in the liver.
3) Silver in solution is generally excreted in the liver bile by using
glutathione (GSH) as a carrier molecule. 
 
Or a combination of the above. For example, silver compounds with a low
solubility in water can have the portion of the compound in solution
removed by the liver using glutathione as a carrier molecule while the
portion not in solution is filtered out by the kidney. 
 
Many forms of selenium complex with silver, forming compounds that are
nearly insoluble and cause the retention of silver in the blood and
tissues. Additionally, silver complexing with selenium can cause a
selenium deficiency leading to liver necrosis. 
 
However, it has been shown that at least one form of selenium does not
complex with silver and that is selenomethionine. In addition,
selenomethionine supports liver synthesis of glutathione thereby
maintaining silver removal by glutathione.
 
The primary reason to take selenomethionine is to maintain the biliary
silver elimination pathway in the liver and the health of the liver. It
is just my opinion but I think a good supplement to help eliminate
silver from the body is glutathione. In addition to taking
selenomethionine.
 
As to how much selenium? Too much selenium can be toxic. Personally, I
would take around 100 to 200 mcg a day. Unless one is fighting cancer
where higher dose may be desirable.
