As we are not doctors, and cannot give medical advice, nothing on this page, or any of our web pages, is to be considered as medical advice.  However, we do offer the following suggestions as to questions that have been asked...

What is the best concentration of colloidal silver to use? How often? Size of dosage?

There are as many opinions about the best parts per million as there are parts per million that can be made.  A great many of my customers have told me that they use a standard solution of about 5ppm and have had great success using a teaspoon a day for general maintenance at that concentration.  For moderate to severe infections (viral, bacterial, fungal, etc.), we suggest  taking a half to a full tablespoon every 2 to 3 hours until the condition improves.

Should there be a replacement of good bacteria, if so what do you recommend?

We have found that when using general maintenance dosages, there isn't really any problems with the internal gut flora.  However, when using higher ppm's, one can take yogurt or acidophilus to compensate for friendly bacteria loss.
