Effects of HCL on Colloidal and Ionic Silver

Effects of HCL (Stomach Acid) on Colloidal and Ionic Silver

Ingested colloidal silver products enter the stomach and mix with the stomach acid before being absorbed in the small intestines. Stomach acid is hydrochloric acid (HCL). In order to determine how the stomach acid effects the antibacterial effectiveness of colloidal silver products we asked the scientists at EMSL to design a test protocol that would simulate the effects of stomach acid on two types of silver products, colloidal and ionic silver.

The scientists at EMSL laboratories tested an ionic silver solution and a high particulate colloidal silver for bacteriology effectiveness after being exposed to HCL (stomach acid) of 3600 ppm, a concentration which is typically present in the stomach. The tests were performed using 1% dilutions of the product directly from the bottle which represents a reasonable concentration that could be generated in vivo (in the bloodstream). The study was conducted as a challenge test against Escgerichia coli (E.coli) bacteria.

The study clearly shows that the effectiveness of the ionic silver product was substantially reduced as a result of being exposed to stomach acid while the colloidal silver product remained effective against the bacteria.
