A recent study by US scientists showed that vitamin C may seriously impair the efficacy of multiple anticancer drugs.
According to a report by the BBC, a study by the Sloan-Gitling Cancer Research Center showed that a series of anticancer drugs were administered to mice injected with vitamin C compared to mice that were not injected with vitamin C. The lethality of cancer cells is reduced by 30% to 70%.
Subsequent chemotherapy tests found that cancer cells in mice injected with vitamin C grew faster.
Some anticancer drugs produce a molecule called oxidative free radical that reacts with other free radicals in cancer cells to kill cancer cells.
In theory, vitamin C can eliminate these free radicals and allow cancer cells to survive in chemotherapy.
But the researchers found that the key issue is not that vitamin C kills free radicals, but that vitamin C seems to protect tiny structures called mitochondria from cancer cells from damage.
Mitochondria are responsible for energy production within the cell and, once destroyed, cause cell death.
Dr. Mark Heine, who is in charge of the study, said that vitamin C appears to protect the mitochondria from damage and thus protects the cells.
The role of all anticancer drugs is to directly or indirectly destroy the function of mitochondria, leading to cell death.
But Dr. Owens of the British Cancer Society said that although the results of this study are very interesting, they are still in the early stages.
