The claim
Posts online say that vitamin C (incl. high-dose) helps with chronic myeloid leukaemia.
Where research stands
We found 7 published papers on vitamin C (incl. high-dose) and chronic myeloid leukaemia. They were published between 2003 and 2024. None of them is a study in people. 1 was a study in animals, and 2 were only in cells in the lab. 2 new studies in people are running or will start soon, say the trial registers.

What the studies found
We have not summed up these studies in words yet. The most important papers are listed under Sources.
Verdict
Vitamin C (incl. high-dose) has been studied for chronic myeloid leukaemia in animals, not yet in people.
Unproven means: it was only tested in animals or cells, or there is too little or mixed data from people. How we rate claims
What this means for you: Results in animals or in cells often do not hold in people. Do not stop or change your medicines because of it. Ask your doctor before you start taking it.
