Comments about Futurebiotics Advanced Colloidal Silver, 4 fl oz:

I use this when I first start to feel the pressure of a sinus infection along with a saline nasal rinse. I used to have 5-7 infections annually to the point where antibiotics no longer got rid of them without 3 cycles. I have not had a sinus infections for more than 4 years. I use the dose of 3 sprays per nostril 3 times a day. My household will not go without it.

This product is known to be used when the first signs of an infection, like a cold, are coming on. It is only intended for short term use, such as a week. I keep it on hand. Colloidal silver was being researched before antibiotics came on the market.
