Ionic nano-particle colloidal silver, 24 parts-per-million in distilled water. This is a relatively strong solution, intended more for fighting active infections than for routine prevention.
Do not mix colloidal silver with any other substances; it is recommended that silver be taken alone. Needs no refrigeration but stays more potent when stored in a cool, dark place.
SPECIAL: Free Bonus 1oz nasal sprayer bottle also filled with 24 ppm colloidal silver when you buy the 2oz dropper bottle! Just select the Special in the dropdown menu.
This strength comes in a stunning two-toned bottle that is even more beautiful than the photos show, which starts at the top in a brilliant raspberry red-pink and fades into an electric blue at the bottom. The 4 oz size comes in a cobalt blue bottle.
