Reviews mention

  • Noticeable, sustained energy boost
  • Vibrant, fruity flavor variety
  • Refreshing, lightly sparkling texture
  • Popular non‑carbonated tea options
  • Very high caffeine content
  • Occasional artificial sweetener aftertaste
  • Jittery, sweaty side effects
  • Inconsistent flavor quality

Celsius earns largely positive reviews for delivering a noticeable energy boost—often used pre-workout or mid-day—with popular flavors like Fuji Apple Pear, Peach Mango Green Tea, and the Vibe series. However, reviews also flag drawbacks: very high caffeine that can cause jitters, migraines, heart palpitations, sweats, or a crash for some; polarizing, sometimes artificial-tasting flavors and aftertaste; skepticism about fat-burning claims; and a switch to sucralose that turns off certain buyers.

  • As final season rolls around, I find myself going to the campus store and purchasing Celsius. With its high caffeine content, I would only drink it if I was severly groggy. The artifical sweet taste is apparent but I'm a berry person so it was fine, does the job. However, I'm looking for energy drink alternatives that are safer and less artificial.

  • So overall, I am not a fan of energy drinks. Although I have, on occasion, been known to drink a watermelon red bull because it tastes soooo good! Other than that, my days of vodka and red bulls are over. Enter: CELSIUS! Not a typical energy drink for sure it does have essential energy but it also accelerates metabolism and burns body fat! Perfect for the gym or some light cardio or really any exercise you enjoy. And with all the different flavors to choose from one things for sure this non-energy energy drink is a total WINNER!

  • The worst drink ever I have seen in my life, if someone didn’t try it I recommend them to never try this drink, at the first time I tried it and after drinking one of them exactly at the night I got really sick and it was for three to four days, then I doubt that it might be cause of Celsius but still I didn’t take it serious, ok sir after two weeks again I tried drunk with one of my friend then we both got sick for one week which more harder more pannier than corona, very bad taste like medicine and very bad result .

  • ill be honest, ive never been a girl who loves energy drinks nor any juices, but I can say i LOVE the celsius drinks especially peach vibe, literally vacation in a can. I just recently started drinking htem as they came to canda about 2 months ago and I especially drink them before the gym. They are the perfect amount of energy needed with the best flavours!

  • I got to try the new Fantasy Vibe and Celsius energy drinks at the Grammy Afterparty thanks to Celsius having a Pop up there and being a sponsor. They were perfect for someone who had cone out from the East Coast of Canada (Hamilton, ON) for a weekend of Grammy themed events, then the red carpet, awards show and afterparty and needed that energy boost! Fantasy Vibe is my favourite! I also really enjoyed Kiwi Guava as my next Fave! Peachy Vibe just arrived in Canada with Kiwi Guava and Tropical Vibe which I was so excited to see! The Peach is really nice and not too sweet. Tropical with it's pineapple and starfruit is a different taste but very interesting. Cosmic Vibe I enjoyed but it is not as good as Fantasy Vibe, Kiwi Guava or Peachy Vibe. They also don't give you the jitters like other energy brands can. We also were spoiled with a certain Bachelor at the event....

  • Celsius is a refreshing and energizing beverage that exceeds my expectations. Its great taste, natural ingredients, and sustainable practices make it a top choice for a healthy energy boost. Highly recommended!

  • I never imagined I’d fall for a crypto romance scam but it happened. Over the course of a few months, I sent nearly $184,000 worth of Bitcoin to someone I genuinely believed I was building a future with. When they disappeared without a trace, I was left heartbroken, humiliated, and financially devastated. For a long time, I didn’t tell anyone. I felt ashamed. But eventually, while searching for answers, I came across a Reddit thread that mentioned Agent Jasmine Lopez a crypto recovery agent. I reached out, not expecting much. To my surprise, she treated me with kindness, not judgment. She used advanced tools like blockchain forensics, IP tracing, and smart contract analysis and with persistence and legal support, she was able to recover nearly 85% of what I lost. I know not everyone gets that kind of outcome, but thanks to Recoveryfundprovider@gmail. com WhatsApp at +44 736-644-5035, I’ve started to reclaim not just my assets, but my confidence and peace of mind. If you’re going through something similar, you’re not alone and there is hope with Agent JASMINE LOPEZ.

  • I’m going to give it another chance, but it was the worst first impression of ANY 0 sugar energy drink I’ve ever tried. Now maybe it was a fluke, maybe I drank it when I should of had more food in my stomach or something, but it made me feel jittery and uncomfortable.

  • I like this brand, and it's been my go-to energy brand for a while now. I remember them using erythritol as the sweetener, but I recently checked and it's now sucralose- which I avoid. I have to find a new energy drink I guess.

  • They started carrying these in the vending machine at work so I tried, and liked, the watermelon and orange flavors but not the tropical ones. They are pretty good for energy drinks but I found them overly sweet (despite having zero sugar) with a little too much caffeine for me.

  • The strawberry flavor is the least artificial flavor. I love the jolt of energy these give me before my workouts. Not sure, I've noticed much of the boosted metabolism that they promote on the can.

  • Celsius is a great energy drink that delivers a refreshing boost without the jitters. The flavors are light and tasty, and I love that it’s packed with natural ingredients. However, the taste could be a bit more balanced, and it’s a little on the pricier side. Overall, it's a solid choice for a clean energy pick-me-up!

  • Celsius is one of my top 2 or 3 go-to's for an energy drink. I really dig it. Pros/cons below. PROS: - Some of the flavors are amazing. All time favorite is the Fuji Apple Pear, but the Cola, Peach Mango, Green Apple Cherry, and the Peach Vibe are all really godo. - The cans are only 12 oz (I hate GIANT energy drinks) - Free of weird creepy energy drink chemicals - uses green tea for caffeine CONS: - Fizzy, which I don't love before a workout. (But they did make some non-fizzy ones recently!) - Some of the flavors are weird. Overall, I recco if you like energy drinks and want to try something that isn't full of mystery chemicals :)

  • I'm writing this review for my dad, but he loves these. Celsius is his drink of choice on road trips, and I think his favorite flavors are the tropical ones. Personally, I don't like energy drinks but my dad is very picky with drinks so it's high praise that he likes Celsius.

  • Ultra sweet chemically flavored energy drink. I've decided if I run into a gas station to purchase an energy drink then I'm going for a classic Red Bull instead of some fake tasting drink.

  • The carbonated version of this energy drink tastes better than the stilled. Since it has stevia in it, they tend to have a lingering aftertaste of sweetness that prolongs in your tongue. I don't really like this so it's not my go to energy drink. They have nice can color variety which is good marketing and their can tops are black which gives it a stylish look.

  • Majorly not a fan. Tasted way too sweet and fake for me. Also too many reports on how bad they are for you.

  • love the flavors and any one of these give me the jitters. i like oasis flavor the best.
