Vitamin C Cuts Cancer Drug Treatment Effectiveness

A laboratory experiment showed that vitamin C lowers cancer drug and treatment effectiveness.

A team of researchers from Memorial Sloan-Kettering Cancer Center in New York City conducted a trial on lab mice. They gave a 2000 milligram dose of vitamin C supplement to mice, which were exposed to human cancerous cells. Two hours later the mice underwent chemotherapy for cancer treatment.

Chemotherapy was conducted with five most commonly used cancer drugs: imatinib, doxorubicin, cisplatin, methotrexate and vincristine. Vitamin C intake was found to be associated with from 30% to 70% decreased tumor cell death.

Chemotherapy drugs are working by damaging the cancer cell mitochondria, which is the cell element responsible for energy production. When cancer drugs damage mitochondria, cancerous cells receive signals of death. Vitamin C itself protects both healthy and cancerous cells from damage. Probably this is why the supplement cuts cancer drug effectiveness.

Since 1970s scientists are looking at how vitamin C can affect cancer treatment and there was a study saying that high doses of it's injection can cure cancer. This is why researchers did not expect controversial results.

However, researchers urge that it is vitamin C supplement conflicting with cancer treatment, natural vitamins in fruits and vegetables will never conflict with any treatment. This is why those undergoing chemotherapy should avoid taking supplements, but they (and everyone else) are always encouraged to eat vitamin rich food.
