A recent study published in Nature has raised alarm about taurine, an amino acid commonly found in energy drinks like Red Bull and Celsius, suggesting it might elevate the risk of blood cancers.
Researchers at the University of Rochester’s Wilmot Cancer Institute found that leukemia cells take in taurine, derived from bone marrow, and use it for growth through a mechanism known as glycolysis. This is basically how cells break down sugars to create energy, which cancer cells exploit for their proliferation.
While taurine is naturally synthesized in the human body and is also present in foods such as meat and fish, it’s frequently added to energy drinks for benefits like enhancing mental clarity and minimizing inflammation. It has, in fact, been used to help ease the side effects of chemotherapy for leukemia patients.
However, this new research suggests that an excess of taurine—particularly from supplements and energy drinks—could worsen leukemia by supplying more energy for cancer cells.
The study involved mice engineered with a specific gene, SLC6A6, which aids in taurine transport throughout the body. Scientists introduced human leukemia cells to these mice to observe their reactions. They discovered that healthy bone marrow cells produce taurine, which is then transported to leukemia cells, potentially aiding their growth.
Researchers highlighted the importance of balancing risks and benefits regarding taurine intake, especially for leukemia patients and those consuming energy drinks, given its prevalent availability.
While the study is still in its early stages, there’s cautious optimism that inhibiting taurine in leukemia cells could pave the way for new treatment strategies. Additionally, the research is part of broader inquiries into whether taurine might play a role in the rise of other cancers, like colorectal cancer.
The American Cancer Society estimates that over 192,000 Americans will receive a blood cancer diagnosis in 2025, which encompasses roughly 66,890 new cases of leukemia, 89,070 new lymphoma cases, and about 36,110 new cases of myeloma.
