Inhibition of Glucose uptake in cancer cells. Malignant cells are known to have an enormous glucose uptake. That’s why I tell everybody that has cancer to immediately (a) get on a ketogenic diet, and (b) take High Dose Vitamin C. Note: Cancer cells consume glucose 200 times faster than ordinary cells. If you study cancer you know of the Warburg Effect. This is the aerobic glycolysis effect and it can be seen on PET scans. It’s pretty obvious. Fenbendazole limits cancer cell fueling with sugar by limiting this glucose uptake, decreasing the amount of what are called “glute transporters” (canals that take the glucose into cancer cells from the blood). An enzyme called hexokinase 2 is inhibited as well. This is very important. It helps those tumors to not divide rapidly and prevent sugar from getting in there.
