Recent research reveals that taurine—a naturally occurring amino acid found in various foods and commonly included in energy drinks and dietary supplements—may inadvertently promote the growth of leukemia cells. This discovery raises concerns that products marketed to enhance energy levels could pose a risk to blood cancer patients during their treatment.

“Our work suggests that developing and testing effective inhibitors of the taurine transporter could lead to new therapeutic options for these deadly cancers,” said Jeevisha Bajaj, an assistant professor in the Department of Biomedical Genetics at the University of Rochester Medical Center and lead study author.

How Leukemia Cells Feed Themselves

The study, published in Nature, suggests that leukemia cells cannot produce taurine on their own and instead hijack specialized transporters to snatch this amino acid directly from the bone marrow, where blood cancers originate. Once absorbed, taurine supercharges the cancer cells’ ability to break down glucose for energy, fueling tumor growth and helping the disease spread.
