Can taking vitamins increase your risk of cancer? Recent studies suggest that routine multivitamin use—especially high-dose antioxidants like Vitamins C, E, or B12—may offer no protection against cancer and could even raise risks in certain groups. This 2026 patient guide breaks down the latest oncology research, clarifies media headlines about "30% increased risk," and offers evidence-based advice for healthy adults, cancer patients, and survivors.
Key takeaways include: why food-first nutrition beats pills, who actually benefits from supplements (e.g., pregnant women, B12-deficient vegetarians), and why self-supplementing during cancer treatment can be dangerous.
