Study links taurine in energy drinks to leukaemia growth

A new study published in Nature suggests taurine, a common ingredient in energy drinks like Red Bull and Celsius, may fuel the growth of leukaemia cells.

Researchers from the University of Rochester found that taurine—an amino acid also produced naturally in the body—can be used by cancer cells as an energy source, potentially making the disease more aggressive.

The study showed leukaemia cells absorb taurine through glycolysis, accelerating their growth. Experiments using mice and human cell samples linked this process to the SLC6A6 gene, which transports taurine from bone marrow to cancer cells.

While taurine is often recommended to cancer patients to ease side effects, the researchers urged caution with supplementation. The findings have also prompted ongoing studies into taurine’s role in other cancers, including colorectal cancer.

Although generally safe in small amounts, high doses of taurine have been associated with side effects. Experts called for further investigation into its impact on cancer.
