Argentyn 23 Bio-Active Silver Hydrosol tastes like water, although sometimes people report detecting a faint metallic taste. This faint metallic taste might feel stronger, usually due to the pH of the mouth when the product was ingested. For example, if you recently drank coffee or orange juice, which are highly acidic, you might be more apt to detect the faint metallic taste. Metabolic changes, such as acidic saliva (most likely due to changes in diet or from dietary choices) could result in a change in the pH of your saliva, which may cause Argentyn 23 to taste stronger (bitter/sour/pungent) than “water with faint metallic taste”. A secondary cause could be leaching of metals from dental amalgams. However, leaching usually only occurs when the saliva is acidic, thus pointing back to a dietary change. You can easily find lists of alkaline foods on the internet. Organoleptic (taste & odor) tests are part of our Quality Control batch release parameters. Our product is manufactured in an NSF-certified GMP facility in the same exact way with the same exact components, each and every time, and we have never released a “bad” batch.
