Most side effects are more likely after long periods of sustained daily usage.One main side effect observed from long-term oral use of Colloidal Silver is the condition argyria, which is a discoloration of the skin to a more greyish appearance. While this is not dangerous by itself, skin discoloration is unlikely to be a welcome side effect.
