Ionic Silver (Silver Ions)
Ionic Silver is one of the most common forms of silver liquid found in the supplement industry today. Many are made by diluting chemical forms of silver, like silver nitrate, to a desired parts per million (ppm), which is then bottled and sold to the public.
Although ionic silver products have the smallest particle size (which they usually tout), they are often the least stable and can easily fall out of suspension.
Additionally, ionic forms of silver only have one mode of action. Once each silver ion steals its missing electron, it becomes neutral and is no longer useful in the body.
Lastly, ionic forms of silver are metabolized, and as a result, can bind up in the body. Over extended periods of time this build up could cause a skin condition known as Argyria, otherwise known as the blue man's syndrome.
Ionic Silver bound to a Protein (Mild Silver Protein)
Mild silver proteins are simply another form of ionic silver. The only difference being that because ionic forms of silver are not generally stable and because they contain unusually large amounts of silver, they are sometimes bound to a protein.
The idea behind binding the ionic silver to the protein is to help make the product more stable than traditional forms of ionic silver, as well as, hopefully making the ionic solution more bioavailable.
However, as a result of this binding with protein, the silver ion is less functional and useful than traditional ionic silver ions. Consequently, higher levels of silver (ppm) are needed to obtain the desired effect.
