In a new study published in Nature, scientists studied how cancer cells interact with their environment in the bone marrow. They discovered that cells in the bone marrow produce taurine, and leukemia stem cells absorb it through a special transporter called TAUT (SLC6A6).

Once inside the cancer cells, taurine fuels a process called glycolysis—a way cells make energy. This helps leukemia cells survive, grow, and resist treatments.

Key takeaways from the study

Leukemia stem cells rely on taurine to grow and thrive.
Blocking the TAUT transporter slows down leukemia progression.
Higher TAUT levels are linked to more aggressive and treatment-resistant leukemia.
Taurine supplements can make leukemia grow faster in lab experiments.

Could Taurine in Energy Drinks Be Harmful?

While the study does not claim that energy drinks cause cancer, it does suggest that taurine can play a role in how cancer cells behave. If someone already has leukemia or is at high risk, taurine could potentially help cancer cells survive longer.

This finding adds to growing research around how the microenvironment of cancer—the tissues and cells surrounding tumors—can influence how cancer grows.

A New Target for Treating Leukemia

The study also found that blocking the TAUT transporter, or reducing taurine in the cancer environment, made leukemia stem cells weaker and easier to kill. Even more promising, researchers discovered that combining taurine blockers with existing drugs like venetoclax (used in leukemia treatment) had a powerful effect in stopping cancer growth.

This opens the door for future therapies that target how cancer cells use nutrients like taurine, instead of just targeting the cells themselves.

Final Thoughts: What You Should Know About Taurine and Cancer

Taurine is a widely used ingredient in energy drinks, but new research shows it may do more in the body than we thought. For people with or at risk of blood cancers like acute myeloid leukemia (AML), taurine might play a role in disease progression.

If you're concerned about how taurine might affect your health, especially in the context of cancer, talk to a healthcare provider. While energy drinks are safe for most people in moderation, this research shows that taurine has complex effects that science is still uncovering.
