The claim
Posts online say that vitamin C (incl. high-dose) helps with myeloproliferative neoplasms.
Where research stands
We found 3 published papers on vitamin C (incl. high-dose) and myeloproliferative neoplasms. They were published between 1954 and 2023. 1 of them is a study in people. None of them compared people who got it with a group that did not. None was a study in animals, and none was only in cells in the lab.

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 in people with myeloproliferative neoplasms, but not in randomised trials.
What this means for you: A study in people is not proof that it helps you. Do not stop or change your medicines because of it. Ask your doctor before you start taking it.
