High-Dose Vitamin C Cuts Death Risk from Stage IV Pancreatic Cancer by 54% and Doubles Survival Time

Before we dig into the extremely promising randomized trial, it’s important to understand that over 100 studies and decades of evidence reveal that vitamin C exerts anti-cancer effects through four powerful mechanisms: pro-oxidative cytotoxicity, epigenetic reprogramming, signaling-pathway suppression, and immune activation. A recent comprehensive review paper titled, High-dose vitamin C: A promising anti-tumor agent, insight from mechanisms, clinical […]

NEW STUDY: High-Dose Vitamin C Is a Promising Anti-Cancer Agent

A major new review paper titled, High-dose vitamin C: A promising anti-tumor agent, insight from mechanisms, clinical research, and challenges, analyzed 150+ studies and found that when vitamin C reaches true pharmacologic levels (20–30 mM), it behaves like a targeted, tumor-selective therapy — something past trials missed by under-dosing. The evidence base spans decades of laboratory, […]

STUDY: Vitamin C + Grape Seed Extract Outperforms Chemotherapy for Tumor Reduction in Mice

A recent preclinical cancer study produced a striking result: in a mouse solid tumor model (Ehrlich carcinoma), a combination of Grape Seed Extract (GSE) + Vitamin C reduced tumor volume more than chemotherapy. Researchers compared multiple treatment arms—including doxorubicin (DOX, nicknamed the “red devil”) as the chemo comparator—and found that the GSE + Vitamin C group showed the greatest mean tumor […]
