1. What Is Sugar-Free Red Bull Made Of?
Letās start by looking at what Sugar Free Red Bull actually contains.
Red Bull Sugarfree Ingredients: Carbonated Water, Citric Acid, Taurine, Sodium Bicarbonate, Magnesium Carbonate, Caffeine, Acesulfame K, Aspartame, Niacinamide, Calcium Pantothenate, Pyridoxine HCl, Vitamin B12, Xanthan Gum, Natural and Artificial Flavors, Colors. (source)
Here are my takeaway points on these ingredients:
- Red Bull Sugarfree is sweetened with aspartame and acesulfame K. These artificial sweeteners are FDA approved but quite controversial. Studies have linked them to an increased risk of cancer, heart disease, brain disease, mood disorders, insulin resistance, and more. Weāll look more closely at them below.
- Red Bull Sugarfree seems to have artificial colors. Strangely, the ingredients list just says āColors,ā not specifying whether they are natural or artificial. But other sources I found refer to them as artificial colors, including red 40. Studies have linked artificial colors to increased risk of hyperactivity in children and possibly cancer.
- Red Bull Sugarfree has caffeine. Caffeine has pros and cons. It may reduce your risk of Alzheimerās and Parkinsonās disease. But caffeine is habit forming, and too much can disrupt your sleep or cause nervousness and other issues.
- Red Bull Sugarfree has taurine. Taurine is an amino acid that may have benefits when taken as a supplement. These benefits may include athletic performance, as well as prevention of diabetes and cardiovascular disease. More on taurine below.
- Red Bull Sugarfree has added B vitamins. This is not a huge benefit, as many B vitamins are easy to come by and may be absorbed better from whole foods anyway. That said, itās kind of nice there are some extra B vitamins in here.
Consumed in moderation, Red Bull Sugarfree may provide a few helpful ingredients like caffeine, taurine, and B vitamins. But is it worth the negatives of the artificial ingredients?
The biggest concern in Red Bull Sugarfree for most people may be the artificial sweeteners. So letās take a closer look at those next.
2. Does Sugar-Free Red Bull Have Artificial Sweeteners?

Red Bull Sugarfree contains the artificial sweeteners acesulfame K and aspartame. These are two of the most widely used artificial sweeteners in the world, and both FDA approved. However, studies have suggested possible links to cancer, heart disease, obesity, stroke, Alzheimerās, depression, and more.
Letās start by discussing aspartame, since itās especially controversial. Itād be hard to cover all of its possible health risks here. If you want to go deep on this subject, start with this page from U.S. Right to Know. That said, Iāll try to summarize.
Some of the biggest concerns with aspartame include:
- Cancer: There has been evidence showing that rodents develop cancer when exposed to aspartame over their lifespan. Aspartame was also posed as a possible explanation for dramatic increases in malignant brain tumors in the years immediately after its approval.
- Heart Disease: Several high-profile cardiologists have sworn off aspartame based on the evidence against this sweetener. A 2014 study found that women who had more than two diet drinks per day experienced more cardiovascular events (like heart attacks).
- Brain Disease: Studies show that consumption of diet drinks is linked to three times higher risk of stroke and dementia. There are also possible connections to Alzheimerās disease, via methanol, which is a breakdown product of aspartame in the body.
- Obesity: This one is quite ironic, as aspartame is used in many ādietā products. But research has linked aspartame to weight gain, along with increased appetite.
- And more: There have been possible links found between aspartame and headaches, mood disorders, learning problems, kidney function decline, diabetes, pre-term birth, and more. Find a more complete list with sources here.
Now, what about acesulfame potassium? This sweetener is often referred to as āacesulfame Kā or āAce-K.ā Here are some concerns people have with it:
- Studies in the 1970s suggested that acesulfame K may cause cancerābut the studies were of low quality. (source)
- A breakdown product of acesulfame potassium, acetoacetamide, may cause damage to the thyroid. (source)
- In a study of lactating women, acesulfame K was the artificial sweetener most found to make its way into breast milk. (source)
Overall, remember: The long-term health concerns with artificial sweeteners are just thatāconcerns. If they were proven to be acutely and definitely unsafe, they would probably not be approved by the FDA and other government bodies around the world.
The important thing is to acknowledge that youāre taking some amount of risk with the artificial sweeteners in Red Bull Sugarfree and other zero-calorie drinks. But you may be just fine, especially in moderation.
3. Is Sugar-Free Red Bull Actually Sugar-Free?
Red Bull Sugarfree is indeed sugar-free. It has no cane sugar, high fructose corn syrup, or other sugars. It has the artificial sweeteners aspartame and acesulfame K instead.
Red Bull Sugarfree is not carb-free, however. It has about 3 grams of total carbohydrates and 5 calories in each 8.4 ounce can.
4. Does Sugar-Free Red Bull Raise Blood Sugar?

I wasnāt able to find any research directly on whether Red Bull Sugarfree raises blood sugar. However, Red Bull Sugarfree contains aspartame and acesulfame K, which may affect insulin resistance based on early animal studies. (source)
Specifically, aspartame and other artificial non-caloric sweeteners seem to alter your gut bacteria. This can affect your tolerance to carbs on an ongoing basis.
A 2014 study on rats found that āaspartame elevated fasting glucose levels and an insulin tolerance test showed aspartame to impair insulin-stimulated glucose disposal.ā
I also found some discussions of artificial sweeteners causing insulin issues through another mechanism. That is, the sweet taste may trigger an insulin response even without real sugar in your bloodstream.
So, proceed with caution. If blood-sugar control is crucial for you, Iād recommend testing whether Red Bull Sugarfree has any affect for you. Also, keep in mind that some effects on your blood sugar may be delayed, via long-term changes in your gut bacteria, which could multiple days or longer.
