How To Compare Colloidal Silver Products

Because there is no accepted standard for reporting the contents of colloidal silver products, producers report the properties of their products in various ways.

You cannot compare ionic silver¹ with colloidal. When comparing colloidal silver within its category, it is best to consider particle size, uniformity, stability, coating, and particle concentration. These properties are verifiable with accurate instruments.

The abnormal but common practice is to report total silver and nothing else. One problem with this is that it lumps silver particles and ions together in a single value, and this is entirely misleading.

Total silver means nothing.

You can compare ionic silver (from salts) between them, you can compare colloidal silver between different colloidal silver products but you cannot compare ionic with colloidal silver. It is like apples and oranges.

If you have silver ions (from salts) their ppm concentration and the salt of origin (nitrate, chlorine, etc) are the only terms of comparison between them.

If you have an ionic silver product then you may have a ppm, but that is debatable as extremely low ppm are ok to be used outside the body. Inside the body, they tie up immediately in the stomach forming silver chloride. After, silver chloride produces unfortunate and dangerous chain reactions, protein denaturation, acidity, and toxicity.

If you have colloidal silver and you want to compare different colloidal silver products then the criteria are: particle size (ideal 10-20 nm), ppm, uniformity of particles, coating, ligands, etc.

When you compare products, proof is required to verify claims. The accepted standard of proof is usually UV-Viz spectroscopy with evaluation of the plasmon band spike. This will prove the particles existence and the degree of uniformity. Sometimes electronic microscopy is used, but there needs to have proper calibration, scale has to be present and correct and many other details.
