Will colloidal silver turn me blue?

Will Colloidal Silver Turn Me Blue?You may indeed turn bluish-grey if you ingest too much large-particle silver protein. This condition, called argyria, is not treatable or reversible and does not have any other known symptoms.
Aside for argyria, excessive consumption of colloidal silver is said to run the risk of kidney damage and neurological problems. After searching extensively, I could find no reports of these issues. Colloidal silver products may also interact with some medications.
You can tell a silver protein solution because it foams when shaken, is usually darker in color, and usually has a very high concentration – typically in the range of 30 to 20,000 ppm. Avoid silver protein.
