Does colloidal silver kill only bad bacteria, leaving good flora unaffected?
Colloidal silver does not discriminate between good and bad bacteria. It destroys all bacteria it comes into contact with. That is why we recommend that if taking more than suggested servings of silver for extended periods of time, one should supplement with acidophilus or eat live culture yogurt an hour or so afterwards to re-supply the digestive system with the good bacteria needed for optimum food digestion and nutrient absorption.
