One main ingredient in your go-to energy drink may be causing more harm than good—particularly to your blood. Taurine, a naturally occurring amino acid and common additive in energy drinks such as Red Bull and Celsius, is now being researched for its involvement in the development of blood cancer, namely leukemia.

Scientists have discovered evidence that taurine could be powering the growth of leukemia cells, a serious health concern for consumers globally who depend on energy drinks as a quick fix on a regular basis, based on a study published recently in the journal Nature.

What Is Taurine?

Taurine occurs naturally in protein-containing foods such as meat and fish and is also produced in the human body. Familiar for its function of maintaining fluid balance, cardiovascular support, and electrolyte regulation, taurine has been touted for years as a "health-enhancing" supplement.

Taurine is also added to energy drinks for its claimed brain-boosting and anti-inflammatory effects and is marketed as a means to enhance mental concentration and physical output. However, whereas the health halo of taurine has been instrumental in fuelling the lucrative energy drink market, recent scientific research contravenes this image.

A new study spearheaded by researchers at the University of Rochester's Wilmot Cancer Institute revealed how leukemia cancer cells hijack taurine as an energy source. Specifically, the cancer cells take in taurine to fuel glycolysis—a biological process that allows them to produce energy and proliferate at a fast rate.

More concerning is the process by which this works. Researchers found a gene, SLC6A6, responsible for carrying taurine throughout the body. When mice were injected with human leukemia cells and put through experiments, the researchers saw that taurine synthesized in the bone marrow was carried directly to the leukemia cells, facilitating their growth and survival.

This opens up a concerning prospect: added taurine from energy drinks and supplements could unintentionally provide nutrients to blood cancer cells, fueling the disease.

Although taurine is naturally occurring and necessary in small amounts, the research indicates that additional, man-made consumption particularly in energy drinks—could cause harm in those who are at risk of or already fighting leukemia. The concern is particularly significant for young adults and adolescents, the group that uses energy drinks most frequently.

Although taurine has been shown in the past to be useful in reducing chemotherapy side effects in leukemia patients, these new results indicate a more complex scenario. Scientists now stress the necessity of reevaluating the extensive use of taurine, particularly considering its easy availability in drinks and supplements.

Notably, research at this stage is in its infancy. Human clinical trials and further research must be conducted to establish causation. That said, early findings have already led scientists to speculate whether preventing taurine uptake in cancer cells might form the basis of future treatment.

Is Taurine Linked to Other Cancers?

The Wilmot Cancer Institute study is part of a larger scientific push to determine how taurine affects other types of cancer. Initial evidence also points to a link between taurine and the formation of colorectal cancer, though further work is required there.

With the American Cancer Society's estimates that over 192,000 individuals in the U.S. will be diagnosed with blood cancer in 2025, including 66,890 new cases of leukemia, these results are both timely and concerning.

Healthier Substitutes for Energy Drinks

For those who wish to cut back on energy drinks but need a boost, there are safer, evidence-based substitutes that offer energy without the possible risks associated with taurine:

1. Coffee

A classic favorite, coffee is loaded with antioxidants and provides a natural source of caffeine. In moderation, it promotes brain health, deters inflammation, and can even reduce the risk of some cancers.

2. Green Tea

Rich in antioxidants and low in caffeine, green tea provides a smooth, long-lasting energy release without jitters or sugar highs. It's also said to boost metabolism and promote cardiovascular health.

3. Yerba Mate

Widely available in South America, Yerba Mate has a blend of all-natural stimulants to enhance concentration and physical performance as well as offering anti-inflammatory and antioxidant effects.

4. Kombucha

A probiotic- and B vitamin-rich fermented tea that supports gut health with a mild energy boost, kombucha is a refreshing and lower-caffeine alternative.

5. Protein Shakes

Most useful after a workout, protein shakes charge up muscle repair and ensure long-lasting energy without sugar overload. They're perfect for gym rats.

6. Chia Seed Water

This water drink contains fiber, omega-3s, and protein to provide a consistent supply of energy and enhanced endurance. It's a no-sugar, all-natural means of remaining energized.

Although further research is required to create definitive health policies regarding taurine intake, the preliminary research serves as a warning call for both consumers and regulators. Modesty will have to do for the time being.

If you’re frequently reaching for an energy drink, it might be time to read the label more critically and consider healthier alternatives. As the science evolves, so should our choices, especially when it comes to ingredients that may carry more risks than rewards.

When we feel a cold coming on, many of us instinctively reach for vitamin C to boost our immune systems. The same applies to when we have an ongoing flu season or any other outbreak. While supplements are convenient, getting vitamin C directly from food can be just as effective—and sometimes even more so. But did you know that besides the most popular Orange, there are a range of popular fruits that are packed with Vitamin C. While a medium-sized orange contains around 70 mg of vitamin C, several other foods pack an even more powerful punch.

Here Are Fruits That Contain More Vitamin C Than Oranges

1. Strawberries

A cup of fresh strawberries offers 97.6 mg of vitamin C, surpassing the amount found in a single orange. Along with their vitamin C content, strawberries provide magnesium and folate, essential for blood sugar stability and heart health.

2. Broccoli

Raw broccoli contains approximately 81 mg of vitamin C per cup — close to the recommended 90 mg per day. Additionally, this cruciferous vegetable is rich in vitamin K, which supports bone health and blood clotting.

3. Bell Peppers

Bell peppers — particularly the yellow variety — can contain up to 341 mg of vitamin C per large pepper, nearly five times that of an orange. Red and green bell peppers also pack a substantial dose of this immune-boosting nutrient and are a low-calorie, fiber-rich snack.

4. Kiwi

The US Department of Health and Human Services (HHS) and the US Food and Drug Administration (FDA) have now begun a comprehensive review of the nutritional value of infant formula. This program by the agencies is dubbed as Operation Stork Speed.

What Is Operation Stork Speed?

This operation aims to review the nutrient content of infant formula. How will it be done? The agencies will increase testing for heavy metals and contaminants in the formula. The agencies will also encourage companies to develop new formulas, and clarify ways to better inform consumers about their ingredients.

The individual nutrient requirements for infant formula are already reviewed at regular intervals, however, this will be the first comprehensive review since 1998.

As part of Operation Stork Speed, the FDA has issued a Request for Information (RFI) to solicit public input on the nutritional composition of infant formula. The agency aims to assess whether existing nutrient requirements should be revised in accordance with the latest scientific evidence, including data from international sources. In particular, the FDA is seeking feedback on potential modifications to current minimum and maximum nutrient levels, as well as recommendations for the inclusion of additional nutrients. Stakeholders are also encouraged to provide information on how such changes may contribute to improved health outcomes for infants.

Electronic or written comments and suggestions must be submitted by Sept. 11, 2025.

In addition to the RFI issued this week, the FDA is enhancing its testing protocols to incorporate more stringent assessments for heavy metals and other potential contaminants in infant formula products. The agency is also urging manufacturers to engage in collaborative efforts aimed at increasing transparency and improving the clarity of product labeling for consumers.

"Protecting our most vulnerable is not just a moral duty -- it is our responsibility," FDA Commissioner Martin A. Makary, M.D., M.P.H., said in a statement. "For many children, infant formula is their only source of nutrition. That's why it's absolutely crucial to continually assess the nutrition standards and incorporate gold standard science to ensure we are providing the safest, most effective nutrition possible."

In June of this year, the FDA will convene a panel of experts to further gather information and expertise. The meeting of the panel will be publicly accessible.

Harmful Contaminants Found In Infant Formula

As per a Consumer Reports (CR) investigation recently, nearly 20 infant formulas found to contain toxic lead, arsenic, or both.

For the analysis, the CR tested 41 types of powdered formula. About half of these samples contained "potentially harmful levels" of at least one contaminant. However, testers also found it "reassuring" that the other half were safe.

Heavy Metals Found In The Formula

The CR investigation found that concerning levels of arsenic and lead were existing in infant formula, particularly in brands like EleCare Hypoallergenic and Similac Alimentum, both manufactured by Abbott Nutrition—the company behind multiple recalls during the 2022 formula shortage.

Arsenic, a naturally occurring but carcinogenic heavy metal (especially in its inorganic form), was found at levels exceeding EPA safety limits for drinking water. Abbott, in response, questioned CR’s testing methods, stating that trace levels of such substances can appear in all formulas and even breast milk. But experts are alarmed. “Long-term arsenic exposure raises cancer risk,” said Dr. Mark R. Corkins of the University of Tennessee. Dr. David Carpenter of SUNY Albany added, “There is no excuse for arsenic in baby food or formula. None.”

Lead, another naturally occurring toxin, was present in nearly all formulas tested, though levels were within FDA limits. Still, experts warn there's no safe level of exposure. “It can impair neurological development,” said Hannah Gardener of the University of Miami, urging manufacturers to conduct rigorous testing and disclose contamination levels.

On a positive note, mercury was not detected in any formulas, and cadmium was found at levels too low to raise concern.
