Vitamin C is good at helping you ward off colds, viruses, and… cancer? New research has not only confirmed the vitamin’s cancer-fighting abilities, but also figured out what makes high doses of vitamin C so dangerous for cancer cells, but harmless for healthy cells.
According to the new research, now published online in the journal Redox Biology, researchers from the University of Iowa found that vitamin C breaks down easily, creating hydrogen peroxide, a reactive oxygen species that causes damage to tissue and DNA.
However, according to the research, cancer cells are much less capable of removing this damaging hydrogen peroxide than normal healthy cells are. Consequently, the team believes that high doses of vitamin C administered intravenously could be effective at helping to fight off cancer when used alongside standard chemotherapy and radiation treatments.
“In this paper we demonstrate that cancer cells are much less efficient in removing hydrogen peroxide than normal cells.
