[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.] I’m a regular Red Bull drinker and especially love the flavored sugar-free options. I was pleasantly surprised by the Zero Sugar Red Bull — it doesn’t have that usual weird aftertaste that most sugar-free drinks have. It tastes a lot like the original Red Bull, just slightly milder. Definitely a great alternative if you’re watching your sugar or calorie intake!

[This review was collected as part of a promotion.] This was my first time trying Red Bull. The flavor was kind of like raspberry but also tropical. The monkey fruit gave it just the right amount of sweetness with no weird aftertaste. It gives you a nice energy boost when you need a pick me up throughout the day. It has zero sugar and is only 10 calories. It was very reminiscent of a soda but without the guilt of sugar.

[This review was collected as part of a promotion.] Okay, Im an avid drinker of energy drinks; this is honestly pretty good in comparison to the rest of the redbulls. But in all honesty I wouldn't go out of my way to buy it. If you have a thing about sugar-free chemicals then this is a good option.

[This review was collected as part of a promotion.] I was pleasantly surprised with the flavor of this! I don’t drink energy drinks often because I’m not so keen on the taste but I actually thoroughly enjoyed this one! It also gave me the perfect amount of energy for when I went into work!

[This review was collected as part of a promotion.] I was excited to receive this Red Bull Zero from influencer! I’ve always liked the sugar free red bull and this one is no different. It’s sweetened with monk fruit so it has a low/zero sugar rating. Would totally drink again! I also love the look of the can. Super cute.

[This review was collected as part of a promotion.] Tried Red Bull Zero for the first time and honestly kind of obsessed. It doesn’t have that super sugary taste like the regular one. It’s more clean and crisp, like a toned down version with a little tang. I actually like it better. I drank it before a study grind and it gave me energy without making me feel shaky or cracked out lol. Also love that it’s zero sugar because my stomach is dramatic and can’t handle those sweet energy drinks sometimes. If you like something light that still wakes you up, this is a solid option. I’d give it like an 8.7 out of 10. Definitely keeping one in my bag for med school survival mode!

[This review was collected as part of a promotion.] I love Red Bull, I would pick a Red Bull over a cup of coffee any day. In the past I only drank the regular sugar, original flavor ones because they taste amazing. (I can't stand the newer flavors like watermelon, coconut and everything.) I didn't think the zero sugar version would be very good but I ended up really enjoying it.

[This review was collected as part of a promotion.] As someone who usually goes for the zero sugar option of energy drinks, this Red Bull tasted pretty good to me. This Red Bull Zero kept me energized without giving me jitters or a crash afterwards. Although it does use the artificial sweetener sucralose, with the addition of the monk fruit extract, I only got a slight hint of that aftertaste you get with diet drinks. The 8.4 fl oz can only has 5 calories so it’s great for those looking for a low calorie energy drink. I can see how this wouldn’t taste great to those who usually drink regular energy drinks but if you’re one who likes zero sugar drinks, this Red Bull Zero drink is a good go to for a pick me up.

[This review was collected as part of a promotion.] Has a nice flavor and can’t tell the difference in taste between the zero sugar and regular one which is usually rare for beverages. I definitely prefer the flavored redbull, but if you like the classics this one is good.
