Celsius Energy Drink Calorie Content

For reference, a standard can of Celsius Original contains 10 calories while the rest of the three versions contains 15 calories.

The calorie content of all the Celsius variants are quite low compared to other energy drinks. For example, an 8.4 fl. oz. Red Bull contains 100 calories, and a 16 fl. oz. Game Fuel has 90 calories.

With this comparison, you can now have a clear idea of how low the amount of calories you’ll get in each can of Celsius.

Celsius, having no caloric value is a reason to not substitute it with meals. Just because it gives you energy, it doesn’t mean you gain nutritional value from it.

As a reminder, the daily recommended calorie intake for women is about 2000 calories and 2500 for men.

Celsius Energy Drink Caffeine Content

The amount of caffeine in Celsius ranges from 100 to 300 mg depending on the version.

Have a look at the table below to get a better view.

VersionCaffeine Amount
Celsius Originals200 mg
Celsius Stevia200 mg
Celsius+Energy100 mg
Celsius Heat300 mg
Caffeine amount in different versions of Celsius

The FDA recommends a daily caffeine limit of 400 mg for healthy adults which is about five cups of coffee.

Too much caffeine can lead to the following symptoms:

  • insomnia
  • restlessness
  • nausea
  • anxiety
  • dizziness
  • irritability

However, we all have different reactions to caffeine and you may not notice any of these symptoms despite exceeding the recommended amount if you have high caffeine tolerance.

But to be safe, I’d like to recommend sticking to one can of any Celsius variant per day because it’s not the only sugary or caffeinated thing in your diet.

Celsius Energy Drink Sugar Content

Celsius is a sugar-free energy drink but it uses sucralose, stevia, and erythritol as sweeteners.

You’re probably aware of the controversies surrounding these groups of artificial sweeteners. Personally, it’s nothing to worry about as long as you limit your intake of anything that has artificial sweeteners.

Moreover, the FDA consider it safe for general use under certain conditions.

I have created this table to show how these sweeteners differ from one another.

Type of SweetenersDescription
Sucralosea zero-calorie sweetener that is 400 to 700 times sweeter than regular sugar
the sweetener used in Celsius Heat
Steviaa zero-calorie sweetener that is up to 200 times sweeter than regular sugar
the sweetener used in Celsius Stevia
Erythritol a type of sugar alcohol used as a sugar substitute
it contains zero calories
used as a sweetener in the powdered version of Celsius
The artificial sweeteners used in Celsius Energy Drinks and their descriptions.

As you can see, Celsius is definitely a fine choice if you’re looking for sugar-free energy drinks.

But don’t get too comfortable because long-term consumption of anything that has artificial sweeteners comes with adverse effects.

And that premise brings us to this strong point – limit your consumption of Celsius to one can per day.

Is it bad to drink 2 Celsius in a day?

Drinking two cans of Celsius in a day could be bad for you, especially when you are sensitive to caffeine.

It can make you feel sick and feel jittery due to the increased amount of caffeine ingested.

Even if you think that you might have high caffeine tolerance, I don’t think consuming two cans of Celsius in a day is a good idea.

It can lead to caffeine discomfort, high blood sugar, and high sugar levels, which are detrimental to your health.

How long do energy drinks stay in your system?

You’ll feel the effects of caffeine in your body after 15 to 45 minutes from ingestion and it will take 5 to 6 six hours to get rid of the caffeine in your bloodstream.

You’ll become more alert, energized, and feel better about yourself after 45 minutes due to the caffeine kick. At this point, the good old caffeine works by temporarily blocking adenosine and releasing dopamine, a “feel good” molecule.

The caffeine subsides after an hour leading sugar crash, fatigue, and tiredness at the same time.

However, this could depend on certain factors such as body type, metabolic rate, and activity level.

Are Celsius drinks bad for you?

Celsius drinks are not bad for you as long as you consume it in healthy amounts.

Ingredients-wise, Celsius is not bad at all because it does not contain sugar, artificial preservatives, flavors, and colors. Plus, it has no traces of high fructose corn syrup!

Moreover, the caffeine amount seems to be intolerable for someone with low tolerance. I suggest going for Celsius BCAA+ if you have low caffeine tolerance, and try the Celsius Heat later when you feel like you are more used to caffeine.

I like my energy drinks to have more or less 150 mg of caffeine per serving and I find the BCAA+ variant a convenient choice.

Speaking of caffeine, Celsius Heat has the highest caffeine in all of the Celsius variants. It contains 300 mg caffeine, which I can pretty much ingest within a day without feeling jittery as long as it’s in healthy intervals.

So, the best takeaway here is to drink in moderation and to listen to your body’s reaction to caffeine.

Therefore, you need to have a proper meal or snack before drinking a can of Celsius!

Celsius Drink Side Effects

In general, long-term consumption of energy drinks can lead to various side effects which can can be alarming to your health if ignored.

Some of the side effecs of drinking too much energy drinks include:

That being said, it is wise to take a break from drinking your favorite Celsius drink once in a while to avoid putting your health at risk.

Here are my recommendations:


I understand the temptation of grabbing a second can of Celsius but I don’t think it is a good idea as it puts your overall health at risk. Overconsumption can lead to caffeine OD, high blood pressure, sleep disorder, and other caffeine-related issues.

One can of Celsius Energy Drink a day is enough to keep you energized throughout the course of your workout.

Celsius definitely delivers when it comes to providing you the ultimate boost that you need. It has no sugar, additives, preservatives, colors, flavors, high fructose corn syrup which makes it a better choice than other energy drinks in the market.

I am not saying this is a healthy drink because energy drinks are rarely healthy. However, Celsius could be a great option if you’re looking for a stronger boost than what coffee can give you.

So, off you go, grab a can of Celsius now!
