How Many Cans of Celsius Can You Have a Day?

Celsius is frequently promoted as a “healthy” beverage since it is sugar-free, preservative-free, and low in calories. Furthermore, it contains natural flavors and plant extracts.

According to the product description, Celsius contains:

A uniquely blended formula with healthy energy and key vitamins, which make CELSIUS an ideal pre-workout drink.

Celsius Product Description
Celsius Energy is often marketed as “healthy” because it has zero sugar and zero preservatives.

But, despite this marketing claim, how can you be certain that Celsius is a healthy beverage? How many cans of Celsius can you drink in a day if it’s sugar-free and preservative-free?

Here’s a short answer: Although Celsius is free of sugar and preservatives, each serving (12 fl.oz) contains 200mg caffeine and should not be consumed over 2 servings, especially by caffeine-sensitive individuals.

If you’re curious as to why you should only drink no more than a can, read along.

Energy drinks are promoted in sports, and some even sponsor sports teams, proving how effective they are at increasing an athlete’s stamina and skill.

As long as the caffeine concentration is within safe limits, energy drinks can help you focus and concentrate better. If you consume a caffeinated beverage, such as an energy drink, your nervous system will be stimulated.

This stimulation will provide you with a brief surge of energy and prevent sleepiness and fatigue. Furthermore, taking energy drinks has been shown in studies to improve cognitive ability.

In Gyms and Workout Routines

Energy drinks help in rehydration and reduce muscle fatigue.

Energy drinks are also often consumed before, during, and after workouts. Energy drinks contain a slew of chemicals, like Amino Acids and caffeine, intended to enhance energy and activate muscles, allowing them to complete their training regimens more effectively.

Furthermore, the carbohydrates in energy drinks give the energy to help postpone weariness and maintain proper hydration.

Celsius Energy Ingredients

In this section, we’ll look at some of Celsius Energy’s most important ingredients and discover what makes Celsius a healthy and safe energy drink compared to other energy drink brands.

CELSIUS is advertised as being free of any preservatives, artificial flavors, and sugars.

Among the ingredients included in CELSIUS are:

  • MetaPlus® Proprietary Blend
    • Taurine
    • Guarana extract (seed)
    • Caffeine (caffeine anhydrous)
    • Glucuronolactone
    • Ginger extract (root)
    • Green Tea Leaf extract (15% EGCG)
  • Carbonated Filtered Water
  • Citric Acid
  • Fruit and Vegetable Juice
  • Sucralose
  • Natural Flavor

Without further ado, here’s a brief breakdown of the ingredients contained in a can of Celsius and whether they are safe enough for you to be consuming multiple times a day.

Sugars and Artificial Sweeteners in Celsius

Celsius contains no sugars in its formulation.

Though it is stated on the label that there are 2 grams of carbs, this is most likely due to the natural sugars contained in its blend (listed as Fruit and Vegetable Juice).

Celsius Energy includes sucralose, an artificial sweetener, in addition to natural flavorings. Sucralose is frequently used as a sugar replacement in sugar-free energy drinks.

Artificial sweeteners are a great sugar substitute.


Sucralose is a zero-calorie sweetener popular in products that avoid sugar but yet want a sweet taste in their food.

Sucralose is reported to be 600 times sweeter than sugar; as a result, only tiny amounts of sucralose are required as long as the sweetness of sugar is met.

Artificial sweeteners are generally safe to use as long as they are not eaten in excess. Artificial sweeteners are ideal for individuals who want to avoid sugar and/or have diabetes because they contain no calories, and just a little quantity is required for sweetness.

For more information about sucralose and artificial sweeteners, here’s a video from Healthline:

Caffeine In Celsius Energy

A can (12 fl.oz) of Celsius Energy contains 200mg of caffeine.

Which is a reasonable quantity of caffeine given that the FDA‘s suggested daily intake is 400mg per day.

Without caffeine, energy drinks are useless. This is due to caffeine’s action as an adenosine antagonist in activating the nervous system. This implies that it inhibits the adenosine receptors (chemicals that cause us to feel sleepy), making us more aware and awake.

Furthermore, caffeine improves focus, relieves weariness, and even improves mental and physical performance, making it popular among athletes and those who pull all-nighters and/or require concentration.

Caffeine may enhance alertness, response speed, and workout performance, but if you are especially sensitive or intolerant to coffee, which many people are, there may be some unpleasant side effects:

  • Restlessness and shakiness
  • Anxiety
  • Rapid heart rhythm
  • Dizziness
  • Headaches

That’s why you should determine your level of caffeine sensitivity before trying out energy drinks with doses up to and above 100mg because these measurements can quickly give you a run for your money.

While Celsius’ caffeine level is still under the maximum daily amount, if you can’t tolerate this much caffeine, then maybe you can try energy drinks that are lower in caffeine, like Mountain Dew Kickstart or Game Fuel

How Many Cans of Celsius Energy Should I Drink In A Day?

As per the Nutritional Facts for Celsius Energy Drink, one can per day is enough to energize and stimulate your system throughout the day. The following table compares the recommended daily intake of calories, sugar, and caffeine to that of Celsius.

Celsius Energy Drink
(12 fl.oz)
Daily Max Limit
Calories10 calories2000 calories/2500 calories
A can of Celsius against standard daily limits.

Moreover, it is explicitly labeled on their can that:

No more than 2 servings of Celsius a day is recommended

Two cans of Celsius Energy Drink would undoubtedly equal the FDA’s recommended daily coffee consumption of 400mg.

While you don’t have to be concerned with the sugar or calorie content of a Celsius, the caffeine amount should be, especially if you have a poor tolerance or aren’t used to so much caffeine.

Caffeine can have negative side effects if used in excess. People who are caffeine sensitive will notice this more immediately.

Side effects include:

  • Insomnia
  • Shakiness
  • Anxiousness
  • Increased Heart Rate
  • Stomachaches
  • Nausea
  • Headaches
  • Dysphoria

Although the can states that two cans are permitted, my recommendation is to limit your use of Celsius Energy Drink to one can per day.

Can I Drink Celsius Energy Everyday?

Although regular consumption of Celsius Energy is not harmful, it is best avoided if you wish to keep your overall caffeine consumption and tolerance at normal levels.

Although Celsius has no sugars or preservatives, it is still wise to limit your total use of such energy drinks. After all, they give short-term boosts and are neither good to incorporate in your everyday diet nor unhealthy to avoid entirely.

Having too much caffeine every day, on the other hand, may eventually lead to you building a tolerance for it, which means you’ll need more caffeine to achieve the same results, not to mention the likely dependency you’ll develop.

That being said, if you want to increase your energy, don’t rely just on energy drinks; instead, maintain a balanced diet and lifestyle. If you’re hesitant about energy drinks, you may try natural energy boosters like coffee, green tea, or yerba mate.

Final Thoughts

Celsius, in my opinion, is a wonderful energy drink that can fulfill its objective of raising your energy levels without you having to worry about the added sugars, calories, or even preservatives, which may not be the case for other energy drinks.

But like advised, it is best to watch your intake of energy drinks such as Celsius and better consume one can in a day, if anything so that you don’t accidentally consume more caffeine than you can handle.

Though it may be promoted as a “healthy energy drink,” I don’t believe there are any healthy energy drinks because most energy drinks are only useful for a short period of time and have little nutritional benefit in the long run.
