Researchers Revisit High-Dose IV Vitamin C for Cancer as 2 Mayo Pill Trials Missed Key Difference

High-dose vitamin C delivered by vein is being re-examined as an experimental cancer treatment after modern studies suggested Linus Pauling's idea was partly right, though not the broad cure he claimed.
IV delivery can push blood vitamin C levels tens to hundreds of times above oral tablets, helping generate hydrogen peroxide around tumors and potentially damaging stressed cancer cells while sparing normal cells.
Small trials in ovarian, pancreatic and brain cancers have found patients can often tolerate infusions several times a week, with some studies showing modest survival gains or fewer chemotherapy side effects but others showing no clear benefit.
The earlier backlash centered on 2 Mayo Clinic trials that tested pills only, a crucial mismatch because the gut caps vitamin C absorption and cannot reach the concentrations seen with intravenous dosing.
Researchers still lack large randomized trials proving IV vitamin C extends life for most patients, so it remains experimental and should be used only in clinical trials or closely supervised medical settings.
If a common vitamin can fight cancer, why aren't definitive trials a top priority?
How does a simple vitamin transform into a selective cancer-killing agent inside the body?
