Energy Drinks Worsening LEUKEMIA?

Popular energy drinks like Red Bull and Celsius contain an ingredient linked to accelerated blood cancer growth, raising serious concerns for leukemia patients and regular consumers alike.

At a Glance

  • Taurine, a common ingredient in energy drinks, may increase the risk of blood cancers like leukemia according to University of Rochester researchers
  • The study found that taurine fuels leukemia cancer cells in bone marrow by enhancing glucose metabolism
  • Blocking taurine from entering cells could potentially slow leukemia progression
  • Leukemia patients are advised to consult healthcare providers before consuming taurine-rich supplements or foods
  • While taurine occurs naturally in the body and protein-rich foods, excessive supplementation raises concerns

Energy Drink Ingredient Under Scrutiny

A new study from the Wilmot Cancer Institute at the University of Rochester has identified a concerning link between taurine, a non-essential amino acid found in popular energy drinks, and an increased risk of blood cancers. The research, published in the prestigious journal Nature, specifically examined taurine’s effect on Acute Myeloid Leukemia (AML), Chronic Myeloid Leukemia (CML), and Myelo Dysplastic Syndromes (MDS). This discovery raises significant concerns about the widespread consumption of taurine-enriched products, particularly energy drinks like Red Bull and Celsius that market the ingredient for its supposed health benefits. 

Taurine naturally occurs in the human body, specifically in the bone marrow, brain, heart, and muscles. It’s also present in protein-rich foods such as meat and fish. However, many people consume additional taurine through supplements and energy drinks. The researchers discovered that leukemia cells in the bone marrow don’t produce taurine themselves but instead rely on it from external sources, including the body’s natural production and dietary intake. This dependency creates a potential pathway for cancer progression that was previously unknown to medical science.

How Taurine Fuels Cancer Growth

The study’s findings reveal that taurine promotes the growth of leukemia cells through a specific metabolic process. When leukemia cells absorb taurine, it enhances glycolysis – the breakdown of glucose for energy – which fuels rapid cancer cell multiplication. Healthy bone marrow cells produce taurine that is then utilized by cancerous cells, creating a dangerous symbiotic relationship within the body. This discovery explains why cancer cells with access to taurine can grow more aggressively and potentially resist treatment efforts.

“The key takeaway from this study is that taurine can be used by leukemia cells to promote cancer progression,” said Jeevisha Bajaj, PhD.  

The research team conducted experiments using mice with the SLC6A6 gene, responsible for taurine transport, as well as human leukemia cell samples. Their findings were consistent across multiple tests, strengthening the evidence of taurine’s role in cancer progression. Of particular interest to researchers was the discovery that blocking taurine’s entry into cells could potentially slow leukemia development, opening a new avenue for therapeutic intervention that could benefit thousands of patients diagnosed with blood cancers each year. 

Implications for Patients and Consumers

For the approximately 135,000 people currently living with blood cancer or related disorders in Australia alone, and the thousands more diagnosed annually worldwide, this research carries immediate implications. Medical experts now advise caution regarding taurine consumption, particularly for leukemia patients. While taurine is sometimes used to alleviate chemotherapy side effects, this study suggests that additional taurine intake might inadvertently worsen the disease by providing fuel for cancer cells. 

According to the study, published in Nature: “Since taurine is a common ingredient in energy drinks… our work suggests that it may be of interest to carefully consider the [risks and] benefits of supplemental taurine in leukemia patients.”

The study does not suggest that energy drinks cause leukemia, but raises valid concerns about whether regular consumption of taurine-enriched products could accelerate disease progression in those already diagnosed or at risk. Dr. Marc Siegel noted that leukemia cells rely on taurine they don’t produce themselves, highlighting the potential danger of supplemental sources. Experts recommend that individuals, especially those with blood cancer diagnoses, should avoid excessive taurine supplementation and consult healthcare providers before consuming taurine-rich products. 

Future Research Directions

This groundbreaking study, funded by several prestigious institutions including the National Cancer Institute and the Leukemia Research Foundation, opens the door to further research exploring taurine’s role in other cancers. Scientists are already investigating its potential impact on colorectal cancer, suggesting the amino acid’s influence may extend beyond blood cancers. The research team acknowledged limitations in their current findings, including the lack of evidence on taurine levels in humans with acute myeloid leukemia, which will likely be addressed in future studies. 

“Our finding that taurine can be produced by the bone marrow microenvironment was completely unexpected and therefore surprisingM,” concludes Jeevisha Bajaj. 

The study emphasizes the importance of understanding the complex relationship between diet, supplements, and cancer progression. By highlighting how a seemingly benign ingredient found in everyday products can impact serious diseases, researchers remind us of the need for continued vigilance regarding what we consume. For the millions of Americans who regularly drink energy beverages for their stimulant effects, this research provides compelling reasons to reconsider consumption habits, particularly for those with family histories of blood cancers or other risk factors.
