FACT CHECK #8WKBHVOB

WHAT WE FOUND

While laboratory and preclinical studies demonstrate that high-dose vitamin C can kill cancer cells without harming normal cells 359, this effect has not been proven to translate into a cure for humans. The Mayo Clinic states there is no evidence that vitamin C alone can cure cancer, though it is being studied as a way to boost the effectiveness of chemotherapy or radiation 4. While some clinical reports and older studies from the 1970s suggested that intravenous vitamin C could prolong the survival of terminal cancer patients 71012, randomized clinical trials have largely failed to verify these findings or demonstrate a clear benefit for cancer treatment 6. Current research highlights high-dose vitamin C as a promising adjuvant therapy that acts synergistically with standard treatments and may mitigate side effects, but it is not an established standalone cure 18. The distinction between oral and intravenous administration is critical, as only intravenous infusion reaches the high plasma concentrations necessary to potentially kill cancer cells in a clinical setting 1.
