The Ultimate Celsius Drinks Review: Benefits, Risks (2026)

If you’re wondering whether Celsius drinks are actually healthy, the short answer is:

Yes, for most healthy adults, Celsius Energy Drinks are one of the better energy drink options available.

Unlike many traditional energy drinks, Celsius combines plant-based caffeine from green tea and guarana with vitamins, minerals, and botanical extracts while avoiding added sugar and many of the artificial ingredients commonly found in competing brands.

Although they aren’t a substitute for quality sleep, good nutrition, or proper hydration, they can be an effective way to increase energy, improve workout performance, and support an active lifestyle when used responsibly.

As a professional basketball player with a Master’s Degree in Nutrition Education, I’ve spent years researching sports nutrition and personally testing dozens of energy drinks, pre-workout supplements, coffees, and natural caffeine sources.

Although I am not a doctor or a registered dietitian, my background in nutrition and professional athletics gives me a unique perspective on the pros, cons, potential benefits, and risks of Celsius energy drinks.

Celsius has become one of my favorite caffeine sources because it consistently provides smooth, sustained energy without the heavy crash I often experience from other energy drinks.

My wife, Anna, and I frequently split a Celsius while traveling, walking, or before workouts, and I’ve recommended them to teammates, friends, and family members who want a cleaner alternative to traditional energy drinks like Monster or Red Bull.

Although Celsius is one of the healthiest energy drinks, that doesn’t mean it’s perfect.

The high caffeine content isn’t appropriate for everyone, the drinks contain sucralose, and some of the company’s marketing claims deserve a closer look.

Whether you’re considering Celsius for weight loss, better workouts, improved focus, or simply replacing your afternoon coffee, it’s important to understand both the benefits and the potential drawbacks before making it part of your daily routine.

Important: While Celsius drinks can be an effective caffeine source to power you through your day, relying solely on caffeine for energy isn’t ideal. Your body needs quality sleep, proper hydration, and a nutrient-dense diet to sustain natural energy levels.

In this evidence-based Celsius review, I’ll break down the ingredients, research, safety, product lineup, and my personal experience using Celsius over several years so you can decide whether it’s the right energy drink for your health, fitness, and performance goals.

If you decide to try Celsius Energy drinks, I recommend the Celsius On-the-Go Packets, which are compact, affordable, and ideal for staying energized anywhere.

You can find them at grocery stores like Walmart or on Amazon, and they are especially convenient if you have Amazon Prime or  Walmart Plus, where they’re often available at competitive prices.

What Are Celsius Drinks?

Celsius drinks are a line of sugar-free energy beverages designed to increase energy, support physical performance, and promote metabolism through a combination of plant-based caffeine, vitamins, minerals, and botanical extracts.

Unlike many traditional energy drinks that rely primarily on sugar and synthetic caffeine, Celsius is formulated with naturally sourced caffeine from green tea extract and guarana, along with ingredients such as ginger root extract, taurine, chromium, and B vitamins.

This combination is intended to provide sustained energy while also supporting focus, thermogenesis, and exercise performance.

Since launching in 2004, Celsius has grown into one of the fastest-growing energy drink brands in the United States by positioning itself as a healthier alternative to conventional energy drinks.

Today, it’s commonly found in grocery stores, gyms, convenience stores, airports, and coffee shops, and has become especially popular among athletes, fitness enthusiasts, students, and busy professionals looking for a convenient source of energy.

Important Reminder: Although Celsius is often marketed as a “fitness drink,” it is still an energy drink.

The primary ingredient responsible for its effects is caffeine, and many of its additional ingredients are intended to complement, not replace, the benefits of regular exercise, quality nutrition, proper hydration, and adequate sleep.

But before we look at the research behind its ingredients, it’s helpful to understand the different Celsius products that are available and how they compare.

Types of Celsius Drinks

One of the reasons Celsius has become one of the most popular energy drink brands is that it offers several product lines designed for different lifestyles and performance goals.

Whether you want a ready-to-drink energy beverage, a portable powder packet for travel, a higher-caffeine formula for intense workouts, or a hydration-focused drink without caffeine, there’s likely a Celsius drink that fits your needs.

Although the formulas share many core ingredients and a similar philosophy of providing cleaner energy than traditional energy drinks, each product line differs in caffeine content, convenience, hydration support, and intended use.

Product	Caffeine	Best For
Celsius Original (Live Fit)	200 mg	Everyday energy, workouts, general use
Celsius On-the-Go Packets	200 mg	Travel, convenience, customizable drinks
Celsius Essentials	270 mg	Experienced caffeine consumers, demanding workouts
Celsius Hydration	None	Hydration and electrolyte replacement without caffeine

For most people, I recommend Celsius Original or Celsius On-the-Go Packets. Both provide an effective amount of caffeine, a well-rounded ingredient profile, and excellent convenience without the excessive stimulant content found in many competing energy drinks.

If you’re highly caffeine tolerant and want a stronger pre-workout boost, Celsius Essentials may be appropriate.

On the other hand, if your goal is simply to replenish fluids and electrolytes after exercise, Celsius Hydration offers many of the brand’s health-focused principles without adding more caffeine to your day.

Let’s take a closer look at each option.

Celsius Original (Live Fit)

Celsius Original, often referred to as Celsius Live Fit, is the company’s flagship product and remains the version most people recognize.

These ready-to-drink 12-ounce cans are available in dozens of flavors, including both sparkling and non-carbonated varieties, making them an easy option for pre-workout energy, afternoon productivity, or replacing sugary energy drinks.

Each can contains 200 mg of naturally sourced caffeine from green tea extract and guarana, along with Celsius’ proprietary MetaPlus® blend, B vitamins, vitamin C, chromium, taurine, and ginger root extract.

The formula is designed to promote sustained energy, improve focus, and support metabolism without added sugar.

This is the version I drink most often.

I find that 200 mg of caffeine provides plenty of energy for lifting, basketball training, or long travel days without feeling excessive.

For most healthy adults, I believe the original Celsius offers the best balance between performance, convenience, and overall health.

Celsius On-the-Go Packets

Celsius On-the-Go Packets deliver the same core formula as the original cans in a lightweight powdered stick pack that mixes with water.

Designed for convenience, each packet contains 200 mg of plant-based caffeine and the full MetaPlus® blend, making it a powerful alternative for those who need clean energy while traveling, commuting, or hitting the gym.

One advantage of the packets is that you control the flavor concentration by adjusting how much water you add.

If you prefer a lighter taste, simply mix the packet into a larger bottle of water.

This flexibility also makes them easy to use before workouts, during road trips, or while flying.

In my opinion, the biggest difference between Celsius powder and cans is that the concentration of Celsius-On-the-Go Packets is customizable: you can choose how much water to add, making them more or less diluted.

These are my personal favorite Celsius products because they’re inexpensive, easy to pack in my basketball bag or suitcase, and available almost anywhere, including Amazon and Walmart.

Celsius Essentials

Celsius Essentials is the strongest product in the Celsius lineup.

When comparing Celsius Original vs Celsius Essentials, the biggest difference is that each 16-ounce can of Celsius Essentials contains 270 mg of naturally sourced caffeine, compared with 200 mg in Celsius Original, making it better suited for experienced caffeine users or particularly demanding training sessions.

The formula retains many of the same ingredients as the original Celsius but increases the stimulant dose to provide a stronger energy boost.

While this can be helpful before long workouts or physically demanding days, it’s more caffeine than many people actually need.

Personally, I rarely choose Celsius Essentials.

Although I tolerate caffeine well, I generally find that 200 mg provides all the energy I need for basketball training and weightlifting.

Unless you already know you perform well with higher caffeine intakes, I think the original Celsius is the smarter choice for most people.

Despite the higher caffeine content, Celsius Essentials still avoids artificial preservatives, added sugar, and synthetic stimulants, delivering clean, functional energy in a stronger dose.

If you’re already a fan of the original Celsius but want something stronger for performance-heavy days, Celsius Essentials is the natural upgrade.

Celsius Hydration

Celsius Hydration expands beyond the company’s energy drinks by focusing entirely on hydration and electrolyte replacement.

Unlike the rest of the Celsius lineup, these products do not contain caffeine, making them suitable for people who want hydration support without additional stimulants.

Instead, Celsius Hydration provides electrolytes and essential vitamins designed to help replace minerals lost through sweat while supporting fluid balance throughout the day.

This makes it a practical option after exercise, during hot weather, while traveling, or anytime you need to rehydrate without consuming more caffeine.

I primarily use traditional electrolyte products after especially intense basketball practices or games, and I like that Celsius recognizes hydration as an important part of athletic performance.

Energy and hydration serve different purposes, and combining the two isn’t always necessary.

If you’ve already consumed enough caffeine for the day, Celsius Hydration can be a better choice than reaching for another energy drink.

My Experience with Celsius Drinks

I’ve been drinking Celsius energy drinks for several years, and they’ve become one of my favorite sources of caffeine for training, travel, and long workdays.

As a professional basketball player with a Master’s Degree in Nutrition Education, I’ve experimented with many, many types of energy drinks, coffee, pre-workout supplements, and natural caffeine sources imaginable, and Celsius has consistently remained part of my routine.

Before discovering Celsius, I primarily relied on caffeinated tea, coffee, or traditional pre-workout supplements when I needed extra energy.

While they can be effective, I found that some pre-workout formulas contained more stimulants than I wanted for everyday use, and coffee wasn’t always practical when I was traveling or heading directly to practice.

Celsius has filled that gap remarkably well.

Unlike many traditional energy drinks, I never viewed Celsius as something to drink simply because I felt tired.

Instead, I use it strategically when I want a convenient source of caffeine before a workout, during long travel days, or when I have several hours of writing, learning, or other mentally demanding work ahead of me.

During my professional basketball career, I’ve spent countless hours traveling between countries, riding buses to away games, sitting through film sessions, and training multiple times each day.

Having a portable energy source that provides consistent energy without requiring me to find a coffee shop has been surprisingly valuable.

That’s one of the reasons I almost always keep a few Celsius On-the-Go packets in my backpack or suitcase.

My wife, Anna, and I also frequently split a Celsius while walking together or traveling.

We both enjoy the flavors, and sharing one allows us to get a moderate amount of caffeine without consuming an entire can ourselves.

While they certainly aren’t perfect, and they won’t replace quality sleep, proper hydration, or a nutrient-dense diet, Celsius drinks offer a cleaner ingredient profile than many competing energy drinks and have consistently helped me maintain energy for training, travel, and long workdays.

That personal experience is one reason I wanted to look beyond the marketing claims and carefully evaluate the research behind the ingredients.

Understanding what’s actually inside Celsius is the best way to determine whether its reputation is supported by science or simply good advertising.

What I Like Most About Celsius

The biggest advantage, in my experience, is that Celsius provides smooth, reliable energy without the heavy feeling I often associate with traditional energy drinks.

The combination of plant-based caffeine, green tea extract, and other functional ingredients seems to produce a more gradual increase in alertness than many products that rely heavily on synthetic stimulants or large amounts of sugar.

I also appreciate that Celsius contains no added sugar.

As someone who pays close attention to my nutrition throughout the year, I would much rather consume my carbohydrates around training sessions than drink them in an energy beverage.

Convenience is another major reason I’ve continued buying Celsius Energy Drinks.

Whether I’m heading to the gym, catching an early flight, or spending the afternoon writing articles for AdamKempFitness.com, I know exactly what I’m getting every time I open a can or mix one of the packets with water.

What I Don’t Like About Celsius

Although I’m a fan of Celsius overall, there are a few things I don’t love.

First, 200 milligrams of caffeine is still a significant dose.

While I tolerate caffeine well after years of using it responsibly, I recognize that this amount can easily cause jitters, anxiety, digestive discomfort, or sleep problems in people who are more sensitive.

I also don’t think Celsius should become someone’s primary solution for low energy.

Key Point: If you’re constantly relying on energy drinks just to get through the day, it’s usually worth looking at the bigger picture first.

Poor sleep, inadequate hydration, insufficient calories, chronic stress, or an overall unhealthy diet are much more likely to be the real issue than a lack of caffeine.

Finally, while I generally trust the ingredient profile, I still believe whole foods, coffee, green tea, and adequate sleep should form the foundation of a healthy lifestyle.

Celsius is a useful tool, but it’s still a processed beverage designed to supplement healthy habits, not replace them.

Which Celsius Products Do I Recommend?

If someone asked me which Celsius product to buy for the first time, I’d recommend either the original 12-ounce cans or the Celsius On-the-Go Packets.

The original cans provide everything most people need without excessive caffeine, while the packets are incredibly convenient for travel and allow you to customize the flavor intensity by adjusting how much water you use.

Personally, the On-the-Go Packets have become my favorite because they’re easy to throw into my basketball bag, backpack, or carry-on luggage, and they take up almost no space.

I’ve used them throughout multiple basketball seasons across Europe because they’re one of the simplest ways to have a reliable pre-workout or midday energy boost wherever I happen to be.

Ingredients in Celsius Drinks

The ingredient profile is one of the primary reasons Celsius has become one of the fastest-growing energy drink brands in the world.

Instead of relying on large amounts of sugar and synthetic stimulants to create a short-lived energy boost, Celsius combines plant-based caffeine, botanical extracts, vitamins, minerals, amino acids, and a calorie-free sweetener to provide sustained energy while supporting exercise performance and metabolism.

Although no energy drink should be considered a replacement for quality nutrition, proper hydration, or adequate sleep, I believe Celsius has one of the cleaner ingredient profiles available.

Many of its ingredients have been individually studied for their effects on energy production, fat metabolism, athletic performance, and overall health, while others primarily improve flavor, stability, or shelf life.

That doesn’t mean every ingredient is equally beneficial.

Some ingredients, such as caffeine and green tea extract, have extensive scientific support.

Others play a much smaller role or simply help improve taste and product consistency.

Likewise, ingredients such as sucralose and the relatively high caffeine content may not be ideal for everyone.

Learning what each ingredient contributes to the formula will make it much easier to decide whether Celsius is a good fit for your health, fitness, and performance goals.

Let’s take a closer look at the key ingredients in Celsius drinks.

Plant-Based Caffeine

Caffeine is the primary active ingredient responsible for the energy, alertness, and performance-enhancing effects of Celsius drinks.

Question: How Much Caffeine is in Celsius Drinks?

Answer: 12-oz Cans and On-the-Go Celsius drinks contain 200mg of caffeine per serving, sourced from green tea and guarana extract, which are safe, plant-derived forms of caffeine. 16-oz Celsius Essentials contain 270mg of caffeine per serving.

Unlike many traditional energy drinks that rely primarily on synthetic caffeine, Celsius energy drinks source most of their caffeine from green tea extract and guarana seed extract, providing approximately 200 mg of caffeine per serving in most products and 270 mg in Celsius Essentials.

Research consistently shows that caffeine can improve alertness, reaction time, endurance, muscular power, and perceived energy while reducing fatigue, and these benefits are among the reasons caffeine remains one of the most effective and well-researched performance-enhancing nutrients available.

As a professional basketball player, caffeine has been one of the most valuable supplements I’ve used throughout my career.

Whether I’m preparing for an early-morning workout, lifting weights, or getting ready for a basketball game, strategically consuming caffeine can noticeably improve both my physical and mental performance.

However, more caffeine isn’t always better.

People who are sensitive to stimulants may experience jitters, anxiety, digestive discomfort, elevated heart rate, or difficulty sleeping.

Important: If you are debating Celsius Original vs. Celsius Essentials, remember that Celsius Essentials has an even higher caffeine content of 270 mg per can, which may be too much for those sensitive to stimulants.

That’s why I generally recommend limiting total daily caffeine intake to within the FDA’s recommendation of approximately 400 mg per day for most healthy adults, while remembering that caffeine from coffee, tea, pre-workout supplements, and other beverages all contribute to your daily total.

Green Tea Extract (EGCG)

Green tea extract provides more than just caffeine, as it also contains epigallocatechin gallate (EGCG), a powerful antioxidant that has been extensively studied for its effects on metabolism, fat oxidation, inflammation, and overall health.

Several systematic reviews suggest that green tea extract may modestly improve body composition by increasing fat oxidation and daily energy expenditure, particularly when combined with regular exercise and a healthy diet (Hodgson et al., 2013).

For example, a 2024 meta-analysis found that green tea extract supplementation significantly lowered body weight, BMI, body fat percentage, and oxidative stress markers while increasing total antioxidant capacity and adiponectin levels (Asbaghi et al., 2024).

Although these effects are generally smaller than many marketing claims suggest, they likely contribute to Celsius’ reputation as a metabolism-supporting energy drink.

Green tea extract also provides antioxidant compounds that help combat oxidative stress generated during exercise and everyday life, making it one of the most valuable botanical ingredients in the Celsius formula.

Guarana Seed Extract

Guarana is another natural source of caffeine included in Celsius drinks.

Native to the Amazon rainforest, guarana naturally contains more caffeine per gram than coffee beans while also providing several plant compounds, such as flavonoids, that may complement caffeine’s effects on focus and mental performance (Hack et al., 2023).

When combined with green tea extract, guarana helps provide the sustained energy that many Celsius users, including myself, find smoother than some traditional energy drinks.

Ginger Root Extract

Ginger root extract is included primarily for its digestive and anti-inflammatory properties.

Research suggests ginger may help reduce nausea, support digestive function, decrease inflammation, and provide antioxidant benefits (Modi & Modi, 2025).

Although the amount found in a single can of Celsius is unlikely to produce dramatic effects on its own, I appreciate that Celsius incorporates functional plant ingredients rather than relying exclusively on stimulants.

Taurine

Despite common misconceptions, taurine is not a stimulant.

Taurine is a naturally occurring amino acid that supports muscle contraction, cardiovascular function, electrolyte balance, and nervous system health.

Research suggests taurine supplementation may improve exercise performance, reduce fatigue, and support recovery during high-intensity exercise (Buzdağlı et al., 2022).

While the amount included in Celsius is relatively modest compared to standalone taurine supplements, it complements the other performance-focused ingredients in the formula.

Vitamins and Minerals

Unlike many traditional energy drinks, Celsius is fortified with several vitamins and minerals that support normal energy metabolism and overall health.

Rather than providing energy directly, these nutrients help your body efficiently convert the carbohydrates, fats, and proteins you eat into usable cellular energy.

Nutrient	Amount per Serving	% Daily Value	Primary Role	Potential Concern	Tolerable Upper Intake Level (UL)
Vitamin C	<60 mg	67%	Supports immune function and acts as an antioxidant.	Very high intakes may cause digestive discomfort or kidney stones in susceptible individuals.	2,000 mg/day
Riboflavin (Vitamin B2)	<1.7 mg	130%	Supports energy production and healthy cell function.	Generally very safe; excess intake may cause bright yellow or orange urine.	No established UL
Niacin (Vitamin B3)	<20 mg	130%	Supports metabolism, digestion, and nervous system function.	Excessive intake may cause flushing and, at very high doses, liver damage.	35 mg/day
Vitamin B6	<2 mg	120%	Essential for amino acid metabolism, brain function, and red blood cell production.	Long-term excessive intake may lead to nerve damage.	100 mg/day
Vitamin B12	<6 μg	250%	Supports red blood cell formation and neurological health.	No known toxicity in healthy individuals.	No established UL
Biotin (Vitamin B7)	<300 μg	1,000%	Supports carbohydrate, fat, and protein metabolism.	Very high intakes may interfere with certain laboratory test results.	No established UL
Pantothenic Acid (Vitamin B5)	<10 mg	200%	Helps convert food into energy through coenzyme A production.	Extremely high doses may cause diarrhea.	No established UL
Chromium	<50 μg	140%	Supports blood sugar regulation and carbohydrate metabolism.	Very high intakes may cause headaches or skin irritation.	200 μg/day

Most healthy adults who consume a balanced diet already meet their daily requirements for many of these nutrients, so they probably aren’t the primary reason Celsius feels energizing.

However, they help support the overall formulation and may benefit individuals whose diets lack certain micronutrients.

Sucralose

To provide sweetness without added sugar or extra calories, Celsius uses sucralose, one of the most widely studied artificial sweeteners available.

Current evidence suggests that sucralose is safe for most healthy adults when consumed within the Acceptable Daily Intake established by regulatory agencies.

A single can of Celsius contains only a small fraction of that limit.

That said, some emerging research suggests frequent consumption of artificial sweeteners may influence the gut microbiome in certain individuals, although the evidence remains mixed and the long-term clinical significance is still being investigated.

Personally, I would prefer if Celsius didn’t rely on artificial sweeteners at all.

However, I also recognize that replacing roughly 25–35 grams of added sugar found in many traditional energy drinks with a calorie-free sweetener is likely a healthier trade-off for most people.

Natural Flavors and Other Ingredients

The remainder of the ingredient list primarily consists of natural flavors, citric acid, beta-carotene, preservatives, and other compounds that improve flavor, color, stability, and shelf life.

These ingredients generally have little influence on the performance or metabolism-related benefits of Celsius but help create the taste and consistency that have contributed to the brand’s popularity.

When evaluating the formula as a whole, I believe the ingredients that matter most are the combination of plant-based caffeine, green tea extract, guarana, taurine, and the overall absence of added sugar.

Those factors are what truly differentiate Celsius from many traditional energy drinks and explain why it has become one of my preferred options for a convenient source of energy before training, traveling, or long workdays.

Pros and Cons of Celsius Drinks

Overall, Celsius drinks are a balanced energy drink with relatively few negative properties and several generally beneficial ingredients.

However, those sensitive to caffeine or specific ingredients should monitor their consumption carefully.

Below are additional details on the pros and cons of Celsius drinks.

Pros: Benefits of Celsius Drinks

Surprisingly, there are more benefits of Celsius drinks beyond a simple energy boost.

Designed with plant-based caffeine, vitamins, and thermogenic ingredients, Celsius energy drinks support fat loss, improve workout performance, and promote metabolic health.

Whether you’re using it as a pre-workout or a midday pick-me-up, Celsius offers a cleaner, more functional alternative to traditional energy drinks.

Let’s take a closer look at some of the key benefits of Celsius drinks:

Weight Loss and Fat Burning Support

Question: Are Celsius Drinks Good for Weight Loss?

Answer: Celsius drinks are good for weight loss as they contain a proprietary MetaPlus® blend, which includes caffeine, green tea extract (EGCG), and guarana seed extract.

In my opinion, Celsius drinks are the best energy drink for weight loss.

Although some people still wonder, “Does Celsius cause weight gain?”, like other high-sugar energy drinks, its ingredients promote thermogenesis, increasing calorie burning and supporting fat loss.

Multiple studies, including research from the University of Oklahoma, have shown that Celsius does burn fat, improve body composition, and increase muscle mass when combined with exercise.

Along with the thermogenic blend, chromium helps regulate blood sugar, reducing cravings and supporting metabolic health (Tsang et al., 2019).

Personally, I’ve noticed a reduction in body fat, especially around my waistline, when using Celsius drinks before workouts.

Although I still enjoy drinking other pre-workout supplements, coffee, and green tea before workouts, Celsius drinks have been the most effective fat burner for me.

Increased Energy and Workout Performance

I drink Celsius before workouts for a clean energy boost that increases alertness, endurance, and focus.

The caffeine stimulates the central nervous system, improving performance and making intense sessions easier to sustain.

Vitamins & Minerals for Overall Health

Celsius is packed with vitamins and minerals, such as Vitamin C, B vitamins, and biotin, which support immune function, energy production, and healthy skin, hair, and nails.

Evidence-Based Claims

​Several studies have investigated the effects of Celsius energy drinks on metabolism, body composition, and exercise performance. 

These studies consistently indicate that Celsius consumption can increase metabolic rate and support improvements in body composition when combined with exercise.​

One study examined the acute effects of ingesting a thermogenic drink (TD) on resting energy expenditure (REE) and serum markers of lipolysis in healthy college-aged individuals. 

The findings revealed that TD consumption significantly increased REE and free fatty acid (FFA) concentrations compared to a placebo, suggesting potential benefits for weight loss and body composition improvement (Dalbo et al., 2008).

Another study assessed the impact of Celsius consumption prior to exercise on body composition and cardiorespiratory fitness in sedentary men and women. 

Participants who consumed Celsius before workouts experienced greater reductions in fat mass, increases in VO₂peak, and improvements in time-to-exhaustion compared to the placebo group. 

This suggests that Celsius may augment the positive adaptations associated with regular exercise (Stout et al., 2008).

A comparative study evaluated the metabolic responses to the acute ingestion of two commercially available soft drinks: Celsius and Diet Coke®. 

The results indicated that Celsius consumption led to a more significant increase in metabolic rate over three hours post-ingestion than Diet Coke®, highlighting its thermogenic properties (Mendel & Hofheins et al., 2007).

Additionally, a study involving previously sedentary men investigated the effects of daily Celsius consumption, with or without exercise, over ten weeks. 

The study found that participants who consumed Celsius and engaged in exercise showed significant improvements in body composition, including decreased body fat and increased lean muscle mass, compared to exercise alone. 

This underscores Celsius’s potential to augment physiological adaptations to combined aerobic and resistance training (Lockwood et al., 2009).

Collectively, these studies suggest that Celsius energy drinks possess thermogenic properties that can increase metabolic rate and, when combined with exercise, may lead to favorable changes in body composition and improvements in exercise performance.​

Cons of Celsius Drinks

Question: Are Celsius Drinks Bad for You?

Answer: While Celsius drinks provide several benefits, there are also some potential downsides and a few concerning aspects to consider. I don’t believe Celsius drinks are inherently bad for you, but you should be cautious when using them, and many people may need to avoid them.

Here are a few cons of Celsius to consider before adding these energy drinks to your diet:

High Caffeine Content (Not Suitable for Everyone)

The high caffeine content in Celsius drinks may cause side effects like jitters, insomnia, or an increased heart rate, especially in individuals sensitive to caffeine.

Monitoring overall caffeine intake is essential to avoid these effects.

Additionally, due to the high caffeine content, Celsius drinks are not recommended for pregnant women, nursing mothers, or children, as they can negatively affect developing systems.

Potential Digestive Issues

While ginger root generally aids digestion, energy drinks like Celsius are known to cause stomach discomfort.

Vitamin Overconsumption

Excessive consumption of vitamins, such as B vitamins or biotin, may lead to side effects like nerve issues or interference with lab tests. Although Celsius drinks are generally safe, it’s important to stay understand the possibilities.

Sucralose

Sucralose is a calorie-free sweetener that is generally safe but may impact gut bacteria, so moderation is advised.

While Celsius drinks contain sucralose, they likely remain well below the ADI of 15 mg/kg body weight, as most energy drinks contain only 20-60 mg per serving, though intake from other sources can add up.

Not NSF or Informed Choice Certified

Celsius drinks contain a clean ingredient list free from banned substances, and I don’t believe Celsius drinks will make you fail a drug test.

However, they lack NSF and Informed Choice certifications, which means there’s no official third-party verification guaranteeing they are completely free from contaminants or trace substances that could pose a risk for tested athletes.

Best Alternatives to Celsius Drinks

If you enjoy Celsius energy drinks but want to explore a healthier alternative, several excellent options deliver clean energy, metabolism support, and additional functional benefits.

As a professional basketball player with a Master’s Degree in Nutrition Education and over fifteen years of experience using supplements and energy drinks, I’ve tested tons of different options.

While I still believe Celsius is one of the healthiest energy drinks, not every energy drink fits every lifestyle, caffeine sensitivity, or wellness goal. Fortunately, there are outstanding alternatives available.

Below are the five healthiest Celsius alternatives based on my personal experience, ingredient analysis, and health impact.

Bloom Energy Drinks

Why it’s a Top Alternative: Bloom Energy Drinks offer a cleaner, slightly lower-caffeine option (180 mg per can) with additional digestive support through prebiotic fiber and apple cider vinegar. The inclusion of L-theanine provides smoother energy without jitters, balancing the stimulant effect of caffeine better than Celsius does.

Key Advantages: Bloom Energy Drinks incorporates prebiotics for gut health and L-theanine for focus, which are two areas where Bloom edges out Celsius (Giesbrecht et al., 2010).

Black Coffee

Why it’s a Top Alternative: Simple and natural, black coffee offers a powerful caffeine boost (100–200 mg per serving) without any additives, sweeteners, or artificial ingredients. Coffee provides antioxidants and mental clarity benefits, though it lacks the thermogenic support of the green extract found in Celsius.

Key Advantage: Most natural, affordable, and flexible option, with easy-to-adjust caffeine content based on brewing method and serving size. I recommend Four Sigmatic Coffee for home brewing, with its unique adaptogenic blends. For example, Happy Gut provides energy while supporting gut health.

What Are the Risks of Consuming Celsius Drinks: Are Celsius Safe?

Celsius drinks have specific advantages as a more natural, healthier energy drink, but they’re not risk-free.

Here is a an analysis of the risks associated with consuming Celsius Drinks regularly:

High Caffeine Content

Each can of Celsius contains between 200 and 270 mg of caffeine, which is about the same as two to three cups of coffee.

For some individuals, this can lead to side effects such as jitters, insomnia, or an elevated heart rate, particularly if they’re sensitive or if other caffeinated drinks are consumed on the same day (FDA, 2022).

Staying within the FDA’s recommended limit of 400 mg of caffeine per day is key to avoiding negative effects.

Artificial Sweeteners and Gut Health

Celsius drinks use sucralose, an artificial sweetener that keeps the drinks low in calories.

While sucralose is generally recognized as safe, some research suggests that consuming it in high amounts may disrupt healthy gut bacteria over time (Ruiz-Ojeda et al., 2019).

Most people won’t reach problematic levels with one can a day, but frequent use alongside other caffeine-containing foods or drinks in your diet can add up.

Risk of Vitamin Overconsumption

Celsius includes high doses of B vitamins and biotin to support metabolism and energy production.

While these nutrients are beneficial, consistently exceeding daily recommended limits by drinking multiple cans plus taking supplements may raise the risk of nerve problems or lab test interference (NIH Office of Dietary Supplements, 2021).

Monitoring your total daily intake helps prevent unnecessary side effects.

Lack of Third-Party Certification

Unlike some sports nutrition products, Celsius is not NSF Certified for Sport or Informed Choice certified.

This means professional athletes or anyone who must pass drug tests should be cautious, as there’s no official guarantee the drinks are completely free from banned substance contamination.

Final Word on Safety

So, are Celsius drinks safe? 

For most healthy adults, moderate use is generally safe as part of an overall healthy routine.

If you’re pregnant, breastfeeding, under 18, or have heart conditions, it’s best to avoid energy drinks altogether and check with a healthcare provider about safer alternatives.

What Was the Celsius Lawsuit About?

Celsius faced a class-action lawsuit due to labeling that claimed their drinks contained no preservatives despite including citric acid, which can act as a preservative.

However, Celsius stated that citric acid was used primarily for flavor enhancement, not preservation.

Overall, the issue is largely about labeling semantics rather than health risks, and Celsius drinks remain a popular choice for those seeking energy and metabolic support.

• What is Citric Acid? Citric acid is a common, naturally occurring compound found in citrus fruits. It’s widely used in food and beverages to improve flavor and maintain acidity. While technically a preservative, it’s also a natural extract.
• Impact on Consumers: The Celsius lawsuit resulted in a settlement allowing consumers who purchased Celsius drinks to claim compensation.

However, the presence of citric acid should not be a major concern for future consumers, as it’s a safe and widely used ingredient in the food industry.

Celsius and High Noon Recall Explained (2025)

What Happened: High Noon has issued a recall for certain High Noon Vodka Seltzer Beach Packs after discovering that Celsius Astro Vibe Energy Drink cans in those packs were accidentally filled with vodka seltzer, not energy drink (FDA).

Why It Matters: This mix-up means consumers may unknowingly drink alcohol, especially dangerous for kids, pregnant women, or anyone avoiding alcohol. The mistake happened because a packaging supplier sent Celsius-labeled cans to High Noon, which were then filled with alcohol and packed into High Noon boxes.

Products Recalled

• High Noon Beach Pack 12-packs (12oz cans) with lot codes:
  • L CCC 17JL25 14:00 to 23:59

• Celsius Astro Vibe Energy Drink – Sparkling Blue Razz Edition with silver lids (not black) and lot codes:
  • L CCB 02JL25 2:55 to 3:11

Where It Was Sold: The affected High Noon and Celsius packs were shipped to stores in Florida, New York, Ohio, South Carolina, Virginia, and Wisconsin between July 21–23, 2025.

What To Do: If you have a Celsius Astro Vibe can with a silver lid, do not drink it. Check the lot code on the can bottom. If it matches the recalled lot, throw it away.

Frequently Asked Questions About Celsius Energy Drinks

Final Thoughts: Are Celsius Drinks a Good Choice for You?

When enjoyed responsibly, Celsius drinks can be a useful choice for anyone who wants a convenient boost of clean energy, better focus, and a little extra support for metabolism and performance.

The blend of plant-based caffeine, green tea extract, and essential vitamins works well to help you feel more energized without the heavy sugars or artificial ingredients found in typical energy drinks.

But, are Celsius drinks good for you? 

For most healthy adults, yes, especially if you drink them in moderation and remember that no energy drink should replace a good night’s sleep, proper hydration, and a well-balanced diet.

I’ve personally found Celsius drinks to be a handy option on busy days or before training, and I appreciate that they fit easily into my routine without the crash I often get from other energy drinks.

That said, everyone’s body is different, so it’s always wise to know your caffeine limits and pay attention to how your body responds.

If you ever feel unsure, consult with your doctor or a qualified healthcare professional to determine if Celsius drinks are a good fit for your goals and lifestyle.

When used sensibly, they can be a useful and enjoyable addition to your routine.
