April 30, 2026 at 6:00 am Vitamins are supposedly good for you, but some might also be good for cancer, Swiss researchers at the University of Lausanne found. Cancer cells have a weakness. They depend on the protein glutamine to produce the energy needed to divide and grow. The Swiss researchers found that cancer cells can escape this weakness with the help of Vitamin B7, or biotin. Without biotin, a protein produced mainly in muscle tissue, cancer cells lose that flexibility and stop growing. “This research opens up new avenues for better understanding the metabolic vulnerabilities of cancers,” the senior author Alexis Jourdain said in a university release , “and for designing innovative therapeutic strategies that take into account the great metabolic flexibility of tumor cells, notably by targeting several metabolic pathways simultaneously.” They published their work in the journal Molecular Cell in February.…
