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.

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.

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

Can you drink too much Celsius?

It is possible to drink too much Celsius, just as with any other caffeinated beverage. Celsius is an energy drink that contains caffeine and other stimulants like taurine and ginger, which can provide a boost of energy and mental alertness. However, excessive consumption of caffeine or stimulants can lead to negative health effects such as:

  • Insomnia or disrupted sleep
  • Anxiety or jitters
  • Rapid heartbeat or heart palpitations
  • High blood pressure
  • Dehydration

It’s important to consume Celsius and other caffeinated beverages in moderation and be aware of the recommended daily intake of caffeine, which is generally considered to be up to 400 milligrams per day for most healthy adults.

Can I drink Celsius on an empty stomach?

It is generally safe to drink Celsius on an empty stomach. However, it’s important to remember that caffeine and other stimulants in Celsius can affect people differently, and consuming it on an empty stomach may increase the risk of negative side effects such as nausea, jitteriness, or stomach discomfort.

If you’re planning to drink Celsius on an empty stomach, you may want to start with a smaller serving size and wait to see how your body reacts before consuming more. Additionally, it’s important to stay hydrated by drinking plenty of water along with Celsius or any other caffeinated beverage.

It’s always a good idea to listen to your body and pay attention to any negative effects or symptoms that you experience after consuming Celsius or other energy drinks.

Is Celsius a pre workout?

Celsius is marketed as a fitness and energy drink, and some people may use it as a pre-workout supplement to help boost energy and performance during exercise. Celsius contains caffeine and other stimulants like taurine, ginger, and green tea extract, which can increase energy and mental alertness. Additionally, Celsius contains some vitamins and minerals that may be beneficial for athletes, such as vitamin C, B vitamins, and calcium.

However, it’s important to remember that Celsius is not specifically formulated as a pre-workout supplement, and there are other products that are specifically designed to enhance athletic performance. If you’re looking for a pre-workout supplement, it’s important to choose a product that is specifically formulated for that purpose and to follow the recommended usage instructions.

When should you not drink Celsius?

Energy drinks like Celsius are commonly taken before and during physical activities. This is exactly the time when one should not consume it. The caffeine and other stimulants in the formula of Celsius can cause jitters and anxiety.

Some people claim it helps keep their focus and energized but the temporary alertness and energy it gives can immediately turn to restlessness and increased heart rate and blood pressure. Continuous consumption of it during strenuous physical activities can be more trouble than its worth in the long run.

Does Celsius actually boost metabolism?

Celsius does not contain any medicinal properties such as increasing metabolism. Though there are some studies that say consumption of the beverage before exercising may fuel calorie-burning activities more. Despite this, it is not attributed to the claims that Celsius can boost a person’s metabolism. 

Instead, it is most likely due to the caffeine content that a person becomes temporarily alert, and hyper in some cases but in reality is because of an increased heart rate and blood pressure. Drinking Celsius energy drinks in moderation is generally safe.

In particular, 1-2 servings per day. It contains caffeine, which can have positive effects such as increased alertness and energy. Furthermore, Celsius has B vitamins, which can aid in the production of energy in the body. It is worth noting, however, that consuming too much Celsius can cause undesirable health consequences such as insomnia, jitteriness, and anxiety.

Why is Celsius banned by the NCAA?

Regrettably, Celsius has been tested and found to contain DMAA. Celsius is sold as a dietary supplement. It does, however, contain a stimulant known as methylhexaneamine (DMAA). The NCAA has prohibited the use of DMAA-containing products because it has been related to cardiac, neurological, and gastrointestinal problems.

Furthermore, DMAA is classified as a stimulant and a performance-enhancing drug, both of which are prohibited in collegiate athletics. As a result, the NCAA added Celsius to its list of prohibited energy drinks.

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.
