Trio, like Fenben Immune Support, is an anthelmintic that loosens the organisms (fungi, yeast, bacteria, parasites, worms, mites, etc.) that are making us sick so that the body can eliminate them. It targets the FTSZ gene and the infected micro tubulin that is being created at a cellular level. Trio treats a wider variety of organisms and is stronger that Fenben Immune Support. Each tablet contains 500 mg fenbendazole, 144 mg pyrantel pamoate and 50 mg praziquantel. These unflavored oblong shaped tablets are scored into thirds for easy dividing. Can be chewed or swallowed whole. 20 tablets per bottle.
