Vitamin C Reduces Chemo Effectiveness in Cancer Cells and Mice

Oncologists often recommend that patients on chemotherapy avoid antioxidant supplements including vitamin C.  Now basic research shows that vitamin C reduces the activity of several different chemotherapy drugs, both in cancer cell lines and in experimental mice. Vitamin C appears to protect the cell against death during chemotherapy by restoring its mitochondria.  Mitochondria power cells, converting nutrients to energy.  When mitochondria are damaged they force the cell to die — the goal of chemotherapy.  By revitalizing damaged mitochondria, the vitamin reduced the effectiveness of all the chemo drugs tested, by as much as 70 percent for some.
