eCS Colloidal Silver 500ml HDPE

It’s very small silver particles suspended in pure pharmaceutical-grade water. Ours is 10 ppm strength (except the throat spray which is 10–20 ppm) and made in our own UK laboratory.

The plain liquid, drops, spray and nasal spray are completely tasteless. The throat spray has a refreshing peppermint flavour. The kids syrup tastes like mild orange.

Our silver product 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, which is highly acidic, you might be more apt to detect the faint metallic taste.

If Colloidal Silver ever tastes stronger (bitter/sour/pungent) than “water with faint metallic taste,” the primary reason would probably be due to metabolic changes, such as acidic saliva, most likely due to changes in diet or from dietary choices, both of which could result in a change in the pH of your saliva. Secondary issues 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.
