Looking at this table, we can ideally tell Celsius is a better option compared to other energy drinks on the market. In my opinion, there’s nothing in it that could be detrimental to your health as long as consumed in moderation.

Now, let’s move on Celsius Energy Drink variants.

Celsius Energy Drink Variants

Celsius Energy Drink comes in 4 variants which are:

  • Celsius Original
  • Celsius Heat
  • Celsius BCAA
  • Celsius-Stevia

By the way, all these variants come with a variety of flavors, and that means you can surely find something to your liking flavor and taste-wise.

To further this, let’s take a closer look at Celsius Energy Drink, in terms of sugar, caffeine, calories, vitamins, and other properties that makes the drink work.

Is Celsius Actually Sugar-free?

Text that says "sugar free"
Celsius is sugar free!

Celsius is 100% sugar free! However, it contains either sucralose or stevia as sugar substitutes.

Celsius, being a sugar-free beverage makes such a drink a better alternative than others as it doesn’t pose any health risks as long as consumed responsibly.

On the other hand, sugar is one of the common ingredients found in standard energy drinks. The body needs sugars for fuel and a good dose of carbs to keep you energized.

According to the American Heart Association (AHA), the safe amount of sugar intake is 25 g per day for women and 37 g per day for men. To put the figures into perspective, 25 g is equal to 6 teaspoons of sugar and 37 g is more or less 9 teaspoons of sugar.

However, exceeding this limit can lead to weight gain, cardiovascular diseases, type 2 diabetes, and many other health hazards.

As I mentioned previously, sucralose and stevia are used as sugar substitutes in Celsius. Read on to get an overview of these two popular sweeteners!


Sucralose is a sucrose derivative that is basically made of sugar and chlorine. Splenda is the most common sucralose-based product, which is a popular sweetener in the US.

Although sucralose is naturally sweet, it has little to no effect on your blood sugar and insulin level but it will depend on you as an individual and whether you’re used to consuming artificial sweeteners. On the other hand, it may raise the blood and insulin levels of people who don’t consume it regularly.

The good thing is, the FDA consider sucralose safe for use within limit.

Stevia is extracted from the leaves of a rebaudiana plant and is the sweetener used in Celsius-Stevia.

It does not contain any calories and still 200 times sweeter than regular sugar. Stevia, being a non-caloric and natural sweetener makes it a better choice health-wise.

A study points to Stevia as something that is beneficial in treating endocrine diseases, such as diabetes and obesity, but more research is needed to prove such a claim.

By the way, the FDA only approved the purified form of Stevia as a safe product to use.

Celsius Caffeine Content

A standard can of Celsius contains 100 to 300 mg caffeine which is still below the recommended intake per day.

This amount of caffeine is certainly enough to give you a quick boost for a few hours. The caffeine in Celsius works by stimulating the central nervous system which leads to increased alertness, better focus, raise in energy levels.

Always keep in mind the recommended caffeine intake which is at 400 mg per day. Going past this limit can lead to overdose with the following symptoms:

  • insomnia
  • headaches
  • fever
  • vomiting
  • palpitations
  • irritability
  • diarrhea

That being said, it is wise to not overindulge and to always listen to your body when ingesting anything that is caffeinated.

Here’s a table showing the amount of caffeine found in Celsius and some popular energy drink brands.

Celsius-Stevia200 mg

Does Celsius Actually Give You Energy?

You can get 10 to 15 calories from Celsius!

Yes, Celsius does give you energy!

You can get 10 to 15 calories from Celsius depending on its variant.

The caloric amount of anything that you ingest is something that you should look out for to avoid health complications such as high blood pressure, weight gain, and other cardiovascular-related conditions.

The calories in Celsius works by providing you the energy to carry on with your activities and exercise. You might think 10 or 15 calories are too low, but you can get enough of it from other food throughout the day.

The FDA recommends everyone to follow the standard 2,000 calorie diet per day to maintain a healthy body. However, this will depend on your age, gender, height, weight, and physical activity.

I suggest using a calorie counter to find out how many calories do you require. There are various online calorie counters that can help you systematically record and monitor your calorie intake.

Does Celsius Help You Focus?

Caffeine helps you focus!

Celsius can definitely help you focus!

For this section, I would like to highlight caffeine, guarana, and ginseng because of their benefits, in terms of helping you achieve better focus.

Caffeine, along with other energy-boosting ingredients in Celsius works by keeping you alert and more focused while exercising or finishing your task.

According to a study, moderate consumption of caffeine improves cognitive function and increases the ability to focus. It also increases alertness, quickens reaction time, and at the same time enhances physical performance.

Another active ingredient in Celsius that helps maintain focus and alertness is guarana. Guarana is a source of caffeine that helps you focus and gain mental energy. Studies also show that low doses of guarana can help improve memory learning and mood.

Ginseng is another ingredient that is responsible for helping you gain better focus. There are studies showing evidence of how ginseng can help improve focus and gives a short-term boost to concentration and learning.

Based on this ingredients, we can quickly tell that Celsius can definitely help you achieve better focus and improve overall cognition.

Is Celsius actually effective?

Celsius is actually effective. The high caffeine level of Celsius Energy makes it effective as an energy drink. Celsius does what it’s supposed to do: it gives you a short boost of energy and makes me more alert right when you need it.

In a number of clinical studies, it was found that consuming CELSIUS before engaging in physical activity led to an increase in metabolic rate, promoted fat loss, and supplied the essential energy required for the needed exercise routines or practices.

Does Celsius actually wake you up?

Celsius energy drinks are designed to increase alertness and wakefulness due to the presence of ingredients like caffeine, taurine, and guarana extract. However, the effectiveness can vary depending on individual factors such as caffeine tolerance and overall health.

It’s important to remember that energy drinks should not replace healthy sleep habits and overall well-being.

Why is Celsius getting sued?

The issue was about them saying their drinks were preservative-free, but turns out they had citric acid in the ingredients. The argument was whether citric acid was there to boost flavor or act as a preservative. Eventually, Celsius had to settle the case.

Celsius got into some legal trouble with a lawsuit over their product labeling.

Is Celsius FDA approved?

Celsius is not FDA approved. Despite the can stating that the advantages to metabolism have been shown in clinical trials, no claims made by Celsius have been approved by the FDA. These drinks are tempting, but excessive use can cause major health issues.

Many people are of the opinion that drinking is still not healthy. The manufacturer does not provide the temperature in Celsius for the guarana seed extract or any of the other goods. The FDA has not given its blessing to the use of guarana.

Can Celsius Help You Lose Weight?

In theory, the Celsius MetaPlus blend can help you lose weight because of its thermogenic supplementation.

The MetaPlus proprietary blend consists of green tea, EGCG, taurine, guarana seed, and ginger root extract, which works well in boosting your metabolic rate in combination with other Celsius ingredients.

The combination of MetaPlus proprietary blend creates a thermogenic reaction that accelerates metabolism, burns fats and calories, and eventually leads to weight loss.

There are a few studies proving the promising benefits of the MetaPlus blend, and if you want to see it, I suggest checking out the Celsius website.

Other Ingredients

To arrive at a better judgment if or not Celsius works, let’s look at some of its notable ingredients.


Taurine in energy drinks like Celsius functions by helping you improve exercise performance. The combination of caffeine and taurine can increase energy levels, improve mental performance and overall brain function. On the other hand, there isn’t enough evidence to support the claim that taurine is effective in boosting energy levels.

Vitamin C

Vitamin C is an antioxidant nutrient that plays a crucial role in providing a decent amount of antioxidants in the body. It also protects us from oxidation and diseases. Vitamin C in Celsius is designed to increase energy levels and boost the immune system to prevent diseases. I think the Vitamin C ingredient in Celsius makes the drink stand out even more.

Vitamin B

B-Vitamins play a key role in various bodily functions such as helping the body convert food into energy, create new blood cells, and maintain healthy brain cells, skin cells, and other body tissues.


Branched Chain Amino Acid (BCAA) is consists of leucine, isoleucine, and valine which are all essential amino acids that play a key role in metabolism. The BCAA in Celsius works by decreasing muscle fatigue and improving endurance. Some related studies also claim that BCAA reduces muscle damage due to high-intensity exercise.


L-Citrulline is a popular supplement for health and exercise performance. The body naturally produces L-Citrulline but taking supplements increases its level which leads to better exercise performance.

Ginger Root Extract

One of the many powerful effects of ginger root extract is it decreases inflammation, swelling, and pain. It also an anti-nausea agent as it alleviates symptoms of nausea and vomiting. I think ginger root extract is an important ingredient in Celsius because it can help reduce muscle inflammation due to exercise.

Is it Bad to Drink Celsius Every Day?

I don’t think it’s bad to drink Celsius every day as long as you stick to a single can per day. This way, you will not put yourself at risk of any side effects.

On a side note:

Overconsumption and long-term use of Celsius and other energy drinks can lead to health complications such as caffeine overdose, poor oral health, and many other conditions.

Caffeine overdose is a common condition that will happen to you if you ingest too much caffeine at a time. The symptoms of caffeine OD normally go away in a few hours.

Tooth decay is another consequence that you’re bound to suffer if you get addicted to drinking Celsius. Celsius and other energy drinks tend to be acidic which damages the enamel of the teeth leading to tooth decay.

To get clear on things, yes, it’s perfectly fine to drink one can of Celsius per day. However, take into consideration the long-term adverse effects that you might suffer because of it.

Nevertheless, drink Celsius in moderation and do your best to not overindulge.

See this video to learn the rules that you should follow if you plan to drink energy drinks every day.

In Summary

To wrap it all up, Celsius Energy Drink definitely works!

Celsius gives you the necessary boost to stay focused and awake – the reason why it’s perfect for when you’re working out or trying to get through a physical job. But for the love of Iron Man, drink it slowly!

In addition, the ingredients and nutrition facts of Celsius tell us that it is indeed a better option if you’re looking for an effective energy booster.

Each can of Celsius is typically stuffed with caffeine, B-Vitamins, and the MetaPlus proprietary blend which works together in providing you with the ultimate boost.

Also, this drink does not include preservatives, additives, artificial coloring, and high fructose corn syrup – I guess for that matter the tagline “Live Fit” suits Celsius!

These all sound good on paper but everything will get messy if you get used to consuming more than one can of Celsius per day. Trust me, don’t even think about drinking that second can to avoid the nasty side effects.

Again, to end things off here, Celsius definitely work!
