In the world of energy drinks, there are seemingly endless options to choose from, varying in shape, size, flavor, and more. Choosing the right energy drink can feel overwhelming, especially when so many options have similar ingredients and caffeine levels.
To help you out, I’m going to compare two of the most popular zero-sugar energy drinks on the market from fitness-focused brands: Alani Nu and Celsius. Both come in a wide variety of flavors, are sold nearly everywhere, and are popular among caffeine connoisseurs.
As a certified nutrition coach who’s consumed countless energy drinks over the years (including both of the brands we’re comparing) I’ve got you covered. In this Alani Nu vs. Celsius comparison, I’ll break down the ingredients in these popular energy drinks, the key differences, and help you decide which popular fitness energy drink is the best choice for your goals.
Note: We’ve seen the recent press release announcing that Celsius Holdings recently acquired Alani Nutrition. However, this review will be based on the formulation of each beverage and our testing experience with both products, as the Alani Nu formulation remains unchanged at the time of writing.

Formulation
When it comes to the formulation, the main ingredients in both products are quite similar. Both energy drinks contain only 10 calories, and provide 200 mg of caffeine, which is a fairly standard dose among energy drinks. In addition to caffeine, both drinks contain ginseng root extract, taurine, theanine, and L-carnitine tartrate; however, only Celsius has added green tea extract for an extra energy boost.
However, aside from the caffeine, the other ingredients are listed in a proprietary blend without precise dosing information, so both drinks only earn 3 out of 5 for the formulation.
There are also smaller differences in the dosing of the vitamins and minerals, which vary slightly between brands.
Both energy drinks contain niacin, vitamin B6, vitamin B12, biotin, and pantothenic acid, which are all various B vitamins. These are often used to promote energy production, however, according to Destini Moody, RD, CSSD, LD, most people get enough B vitamins from their diet, so adding more isn’t necessary.
The last formulation difference is the addition of chromium to the Celsius family. Chromium is thought to improve insulin sensitivity and blood sugar levels. However, recent research1 shows that it has no effects on body composition in healthy individuals.
In other words, while chromium certainly isn’t a bad ingredient to add, healthy individuals likely won’t benefit from consuming it, so you don’t need to choose Celsius just for the added chromium.
Flavor Options
Considering the formulations are so similar, the flavor choices will likely settle the debate for most people.
Flavor is subjective, but it’s worth noting our testers rated Alani Nu higher in the flavor category, giving it 5 out of 5, while Celsius only earned 4 out of 5.
Amanda Dvorak, ISSA-CPT, ISSA-CNC, tested Alani Nu and loves the flavors.
“I got the Cosmic Stardust flavor for testing purposes, but I’ve had several other flavors of Alani Nu in the past: Cherry Slush, Hawaiian Shaved Ice, Breezeberry, Watermelon Wave, and Juicy Peach,” Amanda explains. “There are some I’ve preferred over others, but I’ve enjoyed every one. My absolute favorite Alani flavor is Witches’ Brew, a seasonal fall flavor that’s candy-apple flavored. I was skeptical about it but it is probably my favorite flavor energy drink ever, not just from Alani Nu.”
However, while Alani Nu has 12 flavors and regularly releases seasonal flavors and new releases, Celsius has 29 different flavors, including a variety of fizz-free, non-carbonated options.
As someone who has tried most of the Alani energy drinks and probably 10+ Celsius flavors over the years, I’d agree that Alani Nu has a better taste. Certain Celsius flavors left a bit of a bitter aftertaste for me, but I’ve never had this with Alani Nu.
Caine Wilkes, OLY, CNC, USAW-L1, tried Celsius, and agreed. “I’ve tried several flavors recently, as my gym sells these cans. Peach Vibe was my favorite, although they all have a bit of an artificial tang to me. I think it’s the sucralose. It’s not my favorite taste, but it’s not bad, just not my first pick,” he says.
Overall, we think that Alani Nu has better flavors, but Celsius offers more than twice as many flavors, so you’ll have a wider range of options to choose from if you opt for Celsius.
Company Policies
With both Alani Nu and Celsius, you won’t have a problem finding them. They’re sold in most gas stations, grocery stores, and convenience stores, and both drinks are also available on Amazon.
Alani Nu also sells energy drinks directly through its website, while Celsius’ website redirects to Wal-Mart.
You will likely need to follow the return policy of the individual company or retailer, unless you order directly from Alani Nu, which states that all beverage sales are final, so returns are not accepted.
Both companies offer contact forms that you can use if you need to reach out, and Alani Nu features a live chat option on its website. Both Alani and Celsius also seem active on social media, so you may be able to reach them on Instagram, or other platforms.
Final Thoughts
Both Alani Nu and Celsius are popular, great-tasting energy drinks that are available in a variety of flavors, easy to find, and both contain a 200mg dose of caffeine, along with added vitamins, minerals, and other ingredients to enhance their effects.
The formulations are very similar for both energy drinks, with minor differences that won’t make a significant difference for most people. The primary difference is the flavors.
Celsius has more than twice as many flavors to choose from, but our testers agreed that most Alani Nu flavors are better, although taste is subjective.
Overall, you can’t go wrong with either option, so my advice is to buy a can or two of both to see which you like better before ordering a whole case.
