The Role of High-Dose Vitamin C in Cancer Therapy

The Role of High-Dose Vitamin C in Cancer Therapy 1920 1280 Gary Ruelas, D.O., Ph.D.

Mounting evidence suggests that high-dose intravenous vitamin C holds promise as a potent anti-cancer treatment, demonstrating safety and efficacy in early clinical trials. Recent research highlights its multi-targeting effects, acting as a cancer-specific cytotoxic agent, epigenetic regulator, and immune modulator. Additionally, high-dose IVC shows potential as an adjuvant treatment for cancer, synergizing with standard therapies and mitigating chemotherapy’s toxic side effects.

Read the study below:

“Based on molecular characterization of tumor cells, it is becoming increasingly evident that patient subgroups harbouring certain genetic mutations or overexpressing certain proteins may be particularly susceptible to benefiting from VitC mono- and combination therapies. This holds true for tumors baring KRAS mutations for instance, which are generally difficult to treat, being resistant to targeted anti-EGFR therapy amongst others. In this respect, a further boost for the implementation of high-dose VitC in cancer care is expected to arise from an initiative of the Stand Up to Cancer (SU2C) – American Association for Cancer Research charity program, which is raising money for translational cancer research via broad media awareness campaigns. . .

To conclude, a large body of evidence is accumulating suggesting that VitC, when administered intravenously and in high doses, has potent cancer-selective cytotoxic, cancer-therapy sensitizing and toxicity-reducing properties.

High-dose VitC therefore has the potential to expand the therapeutic range of radio-, chemo- and targeted therapies as well as their efficacy. In addition, a wide variety of cancer patients may benefit from the expanded therapeutic scope of immune checkpoint inhibitors by high-dose VitC.”
