If I want a quick energy drink without a lot of sugar, Red Bull Sugar Free Energy Drink is one of the first options I look at. This version comes in small 8.4 fl oz cans. Each can has 80 mg of caffeine, plus taurine and B vitamins. It has zero sugar and only 10 calories per can based on the current U.S. product information.
In this Red Bull Sugar Free Energy Drink with 80mg Caffeine plus Taurine & B Vitamins, 8.4 Fl Oz, 6 Packs of 4 Cans (Pack of 24) review, I will look at the taste, size, caffeine, ingredients, value, pros, cons, and who I think should buy it.
Red Bull Sugar Free Energy Drink Review: Quick Answer
My quick take: Red Bull Sugar Free is a simple choice for people who want a small energy drink with caffeine but do not want added sugar.
I like the 8.4 fl oz can size because it is easy to finish. I also like that the drink has 80 mg of caffeine per can. That gives me a clear amount without making the can feel too large.
The pack of 24 is also useful if I drink energy drinks often. Instead of buying single cans again and again, I can keep a supply at home, in the office, or in the fridge.
The main downside is the price. A 24-can pack can cost more than some larger energy drinks. I also think the sugar-free taste may not be for everyone.
Overall rating: 4.5/5
What Is Red Bull Sugar Free?
Red Bull Sugar Free is the sugar-free version of the classic Red Bull Energy Drink.
It keeps the main energy drink formula built around:
- Caffeine
- Taurine
- B-group vitamins
- Water
- Sugar-free sweeteners
The 8.4 fl oz can contains 80 mg of caffeine. That is close to the amount found in a typical cup of home-brewed coffee.
The drink uses sucralose and acesulfame potassium instead of regular sugar. So I can get the familiar sweet taste without the sugar found in the original Red Bull.
For me, this makes the drink more appealing when I want caffeine but do not want a sugary drink.
My Red Bull Sugar Free Review
1. Can Size
The first thing I like about this Red Bull is the small can.
Each can is 8.4 fl oz.
That may sound small next to large energy drinks. But I actually see this as a benefit.
I do not always want a huge drink. Sometimes I just want a quick caffeine drink. The small can makes that easy.
It also fits well in a fridge door, lunch bag, desk drawer, or car cup holder.
I can drink the whole can without feeling like I need to carry around a large bottle.
2. Caffeine
Caffeine is one of the main reasons I would buy this drink.
Each 8.4 fl oz can has 80 mg of caffeine.
That is a useful amount for a small can. It is also easy to track because every can has the same amount.
I like this more than drinks where the caffeine amount is very high and easy to underestimate.
The caffeine can help improve alertness and concentration. Of course, people respond to caffeine in different ways.
If I am sensitive to caffeine, I would be more careful about when I drink it.
I also would not stack several cans with coffee or other caffeinated drinks without keeping track of my total caffeine intake.
3. Taste
The taste is one area where personal preference matters.
Red Bull Sugar Free has a sweet, crisp energy drink flavor. It is not the same as a regular soda.
The sugar-free formula also has a slightly different taste from the original Red Bull.
I think it works best when served cold.
For me, cold temperature makes the flavor feel cleaner and easier to drink. I would not choose it because I want a natural juice flavor. I would choose it because I want the classic energy drink taste with no sugar.
If you strongly dislike artificial sweeteners, this may not be your favorite drink.
4. Sugar-Free Formula
This is probably the biggest reason to choose this version over the original.
The current U.S. nutrition information lists:
| Nutrition | Per 8.4 fl oz Can |
|---|---|
| Calories | 10 |
| Total Fat | 0 g |
| Carbohydrates | 2 g |
| Total Sugars | 0 g |
| Protein | 0 g |
| Sodium | 105 mg |
| Caffeine | 80 mg |
So there is 0 g of sugar in each can.
That is a big difference from the original Red Bull Energy Drink.
I like having this option when I want the Red Bull experience but want to avoid the sugar in the regular version.
Taurine and B Vitamins
Red Bull Sugar Free also contains taurine and B-group vitamins.
The B vitamins include:
- Niacin
- Pantothenic acid
- Vitamin B6
- Vitamin B12
Taurine is an amino acid that naturally occurs in the human body.
I would not buy the drink only because of these ingredients. For me, the main reason to drink it is still the caffeine and convenience.
But I like having a formula that includes more than just caffeine.
How Does Red Bull Sugar Free Taste?
The flavor is sweet, light, and fizzy.
I think it tastes best when cold.
The sugar-free sweeteners give it a different finish than regular Red Bull. Some people may love that. Others may prefer the taste of the original drink.
I would describe the taste as:
- Sweet
- Fizzy
- Light
- Slightly tart
- Classic energy drink style
It is not a drink I would compare to fruit juice.
It is made for a different purpose.
How Long Does One Can Last?
That depends on how fast I drink it and how my body reacts to caffeine.
The can itself is small, so I can finish it fairly quickly.
The caffeine does not work like food that simply fills my stomach. Caffeine affects alertness, and the effect can vary from person to person.
For that reason, I would not use the drink as a replacement for sleep.
If I am truly tired, getting proper rest is still the better answer.
Is the 24-Pack Worth It?
This depends on how often I drink Red Bull.
The package includes 24 cans.
The listing describes it as 6 packs of 4 cans, giving a total of 24 cans.
If I drink Red Bull often, buying a larger pack can be convenient.
I do not have to remember to buy another can every day. I can simply keep some chilled at home.
But if I only drink energy drinks once in a while, I would probably buy a smaller quantity.
The 24-pack makes the most sense for regular users.
What I Like About the 24-Can Pack
The biggest benefit is convenience.
I can keep a few cans cold and store the rest for later.
The cans are also easy to separate. I do not need to open a large bottle and worry about finishing it quickly.
For an office, home fridge, road trip, or busy work week, the pack size can be handy.
It also gives me a predictable amount per can.
What I Do Not Like
No product is perfect.
My biggest issue is that the small cans can feel expensive when compared with larger energy drinks.
I also know that sugar-free sweeteners can have a taste that some people dislike.
Another point is the caffeine.
80 mg may feel mild to one person and strong to another. I would pay attention to my own caffeine tolerance.
Finally, the 24-pack is a lot of cans if I do not drink energy drinks often.
Red Bull Sugar Free vs. Regular Red Bull
The biggest difference is sugar.
Regular Red Bull contains sugar. Red Bull Sugar Free does not.
Both versions have the same 80 mg of caffeine in an 8.4 fl oz can.
Both also use taurine and B-group vitamins.
| Feature | Red Bull Sugar Free | Regular Red Bull |
|---|---|---|
| Can Size | 8.4 fl oz | 8.4 fl oz |
| Caffeine | 80 mg | 80 mg |
| Sugar | 0 g | Contains sugar |
| Taurine | Yes | Yes |
| B Vitamins | Yes | Yes |
| Calories | 10 | About 110 |
| Best For | No-sugar choice | Original taste |
If avoiding sugar is important to me, I would pick Sugar Free.
If I prefer the original sweet taste, regular Red Bull may be a better fit.

Who Should Buy Red Bull Sugar Free?

- Want 80 mg of caffeine per can

- Drink energy drinks regularly
- Want a 24-can supply at home

Who Should Skip It?
I would skip this product if:
- I do not like energy drinks
- I dislike sugar-free sweeteners
- I am very sensitive to caffeine
- I do not need caffeinated drinks
- I rarely drink energy drinks
- I want a natural juice or sports drink instead
The small can and sugar-free formula will not appeal to everyone.
Is Red Bull Sugar Free Healthy?
I would not call any energy drink a health drink.
Red Bull Sugar Free does have 0 g of sugar, which may be useful for someone trying to avoid sugary drinks.
But it still contains caffeine.
The right amount of caffeine depends on the person. Healthy adults should keep their total daily caffeine intake in mind, especially when combining coffee, tea, soda, pre-workout drinks, and energy drinks.
Pregnant or breastfeeding people should follow medical guidance about caffeine intake.
I would also check the can label for the latest nutrition and ingredient details because product formulas and labels can change.
How Much Caffeine Is in Red Bull Sugar Free?
Each 8.4 fl oz can contains 80 mg of caffeine.
That is one of the key selling points of this size.
The amount is easy to understand and track.
If I drink one can, I know I am getting 80 mg of caffeine from that can.
Does Red Bull Sugar Free Have Sugar?
No.
The 8.4 fl oz version contains 0 g of sugar.
It uses sugar substitutes to provide sweetness instead.
This is the main reason I would choose Sugar Free over the regular version.
Is Red Bull Sugar Free Good for Work?
Yes, I think it can be useful for work.
The small can is easy to keep in a fridge.
The 80 mg caffeine amount is also simple to track.
If I have a long work session and want a caffeinated drink, the small can is convenient.
I would still avoid using it as a way to replace sleep.
Is Red Bull Sugar Free Good for Studying?
It can be useful for someone who wants caffeine while studying.
Caffeine can increase alertness, which may help when I need to stay focused.
But I would not depend on it for every study session.
Good sleep, food, water, and breaks still matter more.
Is Red Bull Sugar Free Good Before a Workout?
It can provide caffeine, but I would not treat it as a complete workout drink.
It does not replace water.
It also should not be confused with a sports drink designed to replace fluids and electrolytes.
If I use caffeine before exercise, I would consider my total caffeine intake and personal tolerance.
