Vitamin B3 Supplements May Undermine Cancer Treatment, Study Warns
A study from Case Western Reserve University has raised concerns about the use of NAD+ boosting supplements, such as nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR), in cancer treatment. These supplements, popular for their energy-boosting and anti-aging claims, may inadvertently aid cancer cell survival during chemotherapy. The research, published in Cancer Letters, indicates that these supplements can enhance the energy production of cancer cells, reduce oxidative stress, and limit DNA damage, thereby making tumors more resistant to chemotherapy. The study specifically highlights the impact on pancreatic cancer cells, which are notoriously difficult to treat.
