ADDITIONAL INFORMATION: Many customers try to measure the PPM content with a TDS meter. Colloidal metals such as silver or copper cannot be measured with a TDS meter because this type of tool only measures "Total Dissolved Solids" such as salts and other minerals or biodegradable contents. Metal particles do not dissolve and our product is not a result of dissolved ingredients, therefore the TDS meter will not give an accurate measurement of the PPM. Trying to measure the PPM of colloidal copper or silver with a TDS meter is like trying to weigh a needle with a set of bathroom scales.....it is just not designed to do the job. If other brand name products measure higher with a TDS meter it is because there are other dissolved contaminants besides metals that are present in the solution. *Mandatory legal stuff: These statements have not been evaluated by the FDA and none of my supplements are intended to treat, cure or diagnose anything.
