1. Chemical Colloidal Silver will trigger Argyria
2. If you have been making your own Colloidal Silver what did you put into it to trigger the Argyria.
3. If nothing that you particle sizes were too large and getting stuck in the cell membranes.
There is also a chance that you may genetically inclined to turning blue, like the Fugates of Kentucky, an naturally blue skin family. They have been that way for decades if not hundreds of years.
Which is why I always encourage people to get Atomic Particle Colloidal Silver , the particles are way too small to get stuck anywhere.
When a cell dies off and if there is an atomic particle of silver in the cell, that cell along with the silver particle will get excreted with 30 billion other waste cells that the body will not need any more.
When you consider that GoldenGevity Inc., does not use any catalysts at all to make their High PPM Atomic Particle Silver. That is the best way to go if you really think about it.
