Common energy-boosting supplements may help pancreatic cancer cells survive chemo

Pancreatic cancer vaccine shows promise in first human trial Family medicine physician Dr. Jessica Gray details a new experimental pancreatic cancer vaccine showing promise in its first human trial. The vaccine, targeting the KRAS mutation, generated an immune response in 90% of high-risk patients. Dr. Gray discusses the 5-7 year timeline for public availability and emphasizes why pancreatic cancer is so deadly, highlighting advances in cancer treatments.

Over-the-counter anti-aging supplements taken by millions of Americans to boost energy and lessen the side effects of chemotherapy may actually impair cancer treatments, a new study suggests.Researchers at the Case Western Reserve University School of Medicine found that popular vitamin B3 derivatives – including nicotinamide mononucleotide (NMN), nicotinamide riboside (NR) and nicotinamide (NAM) – could help cancer cells survive chemotherapy.Those compounds are used by the body to produce NAD+, a molecule that helps cells generate energy and repair damage.IV THERAPY AND SUPPLEMENTS UNDER SCRUTINY AS EXPERTS WARN OF POTENTIAL SIDE EFFECTSThe study, published in the journal Cancer Letters, examined how these supplements interact with treatments for pancreatic cancer, a particularly deadly form of the disease with a 13% five-year survival rate, according to the American Cancer Society. Over-the-counter vitamin B3 derivatives, specifically NMN, NR and NAM, could help pancreatic cancer cells survive chemotherapy treatment, the study suggests.

As a result, tumors survived chemotherapy doses that typically would prove fatal to them.CLICK HERE TO SIGN UP FOR OUR HEALTH NEWSLETTER”Our findings highlight a potentially concerning role for NAD+-boosting supplements in the context of active cancer, especially when used in conjunction with chemotherapy,” said study lead Jordan Winter, a professor at Case Western Reserve School of Medicine and co-leader of the developmental therapeutics program at the Case Comprehensive Cancer Center, in the press release.CLICK HERE FOR MORE HEALTH STORIES”Our discovery is a call to action for the medical community.”The study notes that these B3 derivatives are not considered dangerous for healthy individuals using them for general wellness. However, the risk becomes significant for patients currently undergoing active cancer therapy. Boosting NAD+ levels provides extra energy to cancer cells, allowing them to repair DNA damage caused by chemotherapy. (iStock)”This research is a critical reminder that ‘natural’ doesn’t always mean safe, especially in the complex biology of cancer treatment,” Winter added.In light of the findings, the research team recommends that oncology teams begin routinely screening patients for supplement use. They also called for more studies into how NAD+ precursors interact with cancer therapies.TEST YOURSELF WITH OUR LATEST LIFESTYLE QUIZWinter urged patients currently in treatment to consult their oncologists before taking any over-the-counter supplements.Because the study relied on laboratory cell cultures and animal models, the findings may not directly translate to how human patients process these supplements during treatment, the team noted. The findings indicate these supplements are not inherently dangerous for healthy individuals using them for general anti-aging or wellness, but pose serious risks when taken during active chemotherapy. (iStock)Additionally, the research focused exclusively on pancreatic cancer, meaning the supplements may not have the same effect on chemotherapy for other cancer types or with different drug combinations.CLICK HERE TO DOWNLOAD THE FOX NEWS APPThe study also only evaluated short-term cellular responses under controlled laboratory conditions and not human clinical trials, so it remains unclear how these supplements could affect cancer patients over time.Fox News Digital reached out to multiple NAD+ supplement manufacturers for comment.
