Silver Excelsior Serum is our patented chelated silver oxide complex, not colloidal silver. This allows for better bioavailability and biocompatibility so that the body’s cells will much more readily adsorb our silver oxide without affecting benefits from helpful probiotics. At 4000 PPM in Kosher vegetable USP Grade glycerine, Silver Excelsior Serum is in concentrated form - 1 drop to 1 fluid ounce of distilled water provides 150 ppm chelated silver oxide, which is 15x more concentrated than most colloidal silver products currently offered. This product can be stored at room temperature.
