High-Dose Vitamin C (PDQ): Patient Version

The National Cancer Institute's current, expert-reviewed patient-facing summary of high-dose vitamin C as a cancer therapy. Last-revised date (28 May 2024) and publisher confirmed by direct fetch. States plainly: 'The U.S. Food and Drug Administration (FDA) has not approved the use of high-dose vitamin C as a treatment for cancer or any other medical condition,' and that human studies to date show mixed quality-of-life results without established anti-cancer efficacy. This is the present-day-critique source for the case's active-enterprise (current_status: both) requirement: high-dose/IV vitamin C is still marketed by integrative and naturopathic clinics today, and this is the current federal expert assessment of it.
