What is silver protein?
Most products claiming to be high concentrations of colloidal silver (typically in the range of 30 ppm or higher) are in fact silver protein products. While some of these products are labeled as Silver Protein or Mild Silver Protein, many such products are simply labeled as colloidal silver and the word protein does not appear anywhere on the label or in the product advertising literature.
Composition of silver protein
Silver protein products generally have very large silver particles, so large that they would not remain suspended as colloidal particles without protein additives. Of the three types of colloidal silver, silver protein products have the lowest Particle surface Area for a given concentration. This makes the silver inaccessible for safe human absorption and less effective for human use. Particle Surface Area, as we have previously discussed, is the single most important determinant of colloidal silver effectiveness.
Risks of silver protein
Silver protein products have numerous dangers. Due to the high concentration of large silver particles, silver protein products are known to cause argyria, a condition that causes the skin to turn bleu-gray. Crystal silver is not a silver protein and does nor cause argyria. Further, adding protein to colloidal silver supports the growth of bacteria in the product, according to Professor Ronald Gibbs who discussed this fact in his booklet "Silver Colloids."
How can I recognise silver protein?
You can recognise silver protein products in three ways:
1. The colour: this generally varies from light-orange to almost black. The higher the ppm concentration, the darker the liquid is.
2. Shaking: If you shake the product, a layer of foam forms on top of the liquid that remains in place for several minutes.
3. Higher concentration: silver protein products generally have very high concentrations of 30 ppm or more.
