[This review was collected as part of a promotion.] This energy drink had good flavor, and was not overly sweet or tart. I also feel that the carbonation was good without being overwhelming. My only downside was that it only contained 80mg of caffeine, which did not make much of a difference in my energy levels. It’s possible my body is accustomed to the higher levels in other drinks (200mg). Although tasty, I’m not sure I would grab this one first if I needed an energy pick me up.

[This review was collected as part of a promotion.] I haven’t ever drank redbull, so I was a little nervous. I have a bunch of chores I need to do today but don’t really have the energy to. I decided I would try this and see if it helps. It smells pretty fruity and sweet when you first open it. The taste is actually very good. I love that it’s zero sugar and sweetened with monk fruit extract. It’s also a low calorie drink(only 5 calories for the can). I would definitely try again and would also be interested in trying other flavors.

[This review was collected as part of a promotion.] Red bull has always been a favorite of mine! Until I stopped drinking sodas and all the sugar!!! I was nervous about drinking the zero sugar bc gross right?! WRONG! these are absolutely delicious and i love the pick me up.

[This review was collected as part of a promotion.] As someone who regularly reaches for energy drinks, Red Bull Zero is a reliable go-to when I want that signature Red Bull kick without the sugar. It has the same familiar flavor profile—slightly tart, slightly sweet—with a noticeably lighter body. The sweetness from artificial sweeteners is present but not overpowering, and the aftertaste is cleaner than I expected. Energy-wise, it delivers. I feel more alert within 15–20 minutes, and the boost lasts a solid few hours without a crash. It’s perfect for those mid-afternoon slumps or early morning starts when I want to avoid sugary options. If you’re already a fan of the original Red Bull and looking for a zero-calorie alternative, this one hits the mark. It’s not revolutionary, but it does exactly what it’s supposed to—and does it well.

[This review was collected as part of a promotion.] Has zero sugar and is 5 calorie per can. Taste refreshing and great. Opened this can in the afternoon while almost falling asleep. This drink really did wake me up. Contains 80mg of caffeine per can.

[This review was collected as part of a promotion.] When I drank it I felt more sick than energized. Half way through the can I threw it way. It tasted fine but wouldn't be something that I would grab. The only thing I can say it like it's that it's a zero sugar.

[This review was collected as part of a promotion.] Just tried the Zero Sugar Red Bull, and honestly—I’m impressed. For a zero-sugar drink, it actually tastes really good. No weird aftertaste, no chemical vibes—just that classic Red Bull flavor, crisp and energizing. If you’ve been hesitant about sugar-free energy drinks because of taste, this one changes the game. It’s packed with caffeine (80mg per can), B-vitamins (like B6 and B12 for energy metabolism), and taurine—everything you’d expect from Red Bull, minus the sugar. And at only 10 calories per can, it’s perfect if you’re watching your intake but still need a kick. It’s priced the same as the regular Red Bull, which means you’re not paying extra to skip the sugar. Great taste, same energy, no crash—and no guilt. If you’re looking for a better-for-you energy option that still delivers, this is a solid pick. Definitely staying stocked in my fridge. #ZeroSugarRedBull #EnergyWithoutTheCrash #NoSugarAllWings

[This review was collected as part of a promotion.] This was my first time ever trying a Redbull and I was pleasantly surprised! It is very sweet but I am a sweet tooth so I love that. The carbonation in the drink is perfect - not too carbonated. I love the fact that it only has 5 calories and no added sugars.

[This review was collected as part of a promotion.] The packaging is nice and I like the colors it's a good value for the price of redbull which is often on sale. I have always loved the taste of redbull original flavor. I'm excited the ingredients in this version give me peace of mind when I need something effective for energy but want to be healthy as possible too.

[This review was collected as part of a promotion.] gave me energy at work but i didn’t even finish it because i couldn’t stand the taste - just like melted bubblegum and nightmare fuel if you mix it with vodka (don’t ask). cute packaging - less cute when i threw it in the trash after braving my way through half the can.
