Selenium Deficiency Is Associated with Pro-longevity Mechanisms

Researchers propose this mechanism could show selective toxicity toward cancer cells because: Tumor cells often lack catalase and other peroxide-neutralizing enzymes Cancer microenvironments contain elevated labile iron levels Normal cells maintain robust antioxidant defenses Clinical Trial Evidence Recent Phase II trials investigating vitamin C injections in cancer treatment have reported early signals that researchers describe as promising, though the evidence remains preliminary: Pancreatic Cancer Study: In a randomized Phase II trial of 34 patients with stage 4 metastatic pancreatic cancer led by Joseph Cullen at the University of IowaPharmacological ascorbate in combination with gemcitabine and nab-paclitaxel published in Redox Biology (2024)participants who received 75 grams (75,000 mg) of IV vitamin C three times weekly alongside standard chemotherapy reached a median overall survival of 16 months, compared with 8.3 months for chemotherapy alone
