Is Celsius Bad For You?

Celsius Energy Drink has gained popularity as a healthier alternative to traditional energy drinks. However, an analysis of its ingredients reveals that it might not be as healthy as claimed.

  • Taurine, an active ingredient in Celsius, is not medically proven to increase energy and may pose risks to adolescents when combined with caffeine.
  • Glucuronolactone, another stimulatory ingredient, is likely effective for improving energy and attention, but when used in combination with caffeine and taurine, it can cause negative changes to blood pressure and insulin sensitivity.
  • Ginger extract and green tea leaf extract, both present in Celsius, have been shown to increase energy. Still, their effectiveness is questionable due to the vastly lower doses used in the drink.
  • Celsius also contains added vitamins and minerals, which have no clinical evidence of increasing energy in those without a deficiency. The three inactive ingredients in Celsius, such as citric acid, could cause inflammatory reactions in some individuals.

Overall, Celsius may not be actively harmful, but it is not recommended to drink regularly. Let’s go into more detail:

Caffeine Content

Celsius Energy Drink contains 200mg of caffeine per 12oz can, equivalent to two cups of coffee. While this level of caffeine may provide a caffeine boost, it may also pose a risk to the nervous system, especially if a person is not accustomed to consuming caffeinated beverages.

Celsius Energy Drinks claim to be a healthier option compared to older-generation energy drinks like Red Bull and Monster. However, the large supplement facts label, which lists various questionable active and inactive ingredients, suggests otherwise. While Celsius Energy Drinks may not be actively harmful, regular consumption is not recommended.

Sugar Content Or Artificial Sweeteners

Celsius Energy Drink has a minimal sugar content as it is sweetened with a blend of artificial sweeteners like stevia, erythritol, and sucralose. In contrast, other energy drinks like Red Bull contain high levels of regular sugar, which can contribute to chronic illnesses if consumed regularly.

Poon, a certified nutritionist and Reiki master advises consumers to look for naturally sweetened, low-sugar options and to stick to drinks with simple and recognizable ingredient lists. While Celsius might seem like a healthier energy drink option, it’s important to note that artificial sweeteners can still negatively affect health if consumed in excess.


Celsius Energy Drink is low in sodium, with a 0mg per 12 fl. ozcan. This makes it a good drink option for individuals who are mindful of their sodium intake as well as for those who are on a low-sodium diet. High sodium intake can lead to health problems such as high blood pressure, stroke, and heart disease. Drinking Celsius Energy should not increase an individual’s sodium intake drastically. Overall, for healthy individuals and those with dietary restrictions, the low sodium content in Celsius Energy Drink makes it a safe beverage option. 

What Is Taurine And Is It Safe To Consume In Celsius Energy Drink?

Taurine is an amino acid present in Celsius Energy Drink. Medical studies on the effectiveness of taurine in increasing energy are lacking, but it is generally recognized as safe to consume in moderate amounts. However, adolescents and children are recommended to avoid this ingredient in combination with caffeine, which is also in Celsius, due to potential risks to the brain. Overall, taurine is not considered harmful and can be safely consumed as long as the drink is consumed in moderation.

Vitamins and Minerals

Celsius Energy drink has a variety of vitamins and minerals included in its ingredient list. Each 12 fl. oz can contain 60mg of vitamin C, 1.7mg of riboflavin (vitamin B2), 20mg of niacin (vitamin B3), 10mg of pantothenic acid (vitamin B5), 2mg of pyridoxine (vitamin B6), 300mcg of biotin (vitamin B7), 6mcg of cobalamin (vitamin B12), 50mg of calcium, 50mcg of chromium, and 0g of sodium.

While these vitamins and minerals are essential for the proper functioning of the body, it is important to note that the amounts contained in a single can of Celsius may not be enough to meet the daily recommended intake.

Therefore, consuming a balanced diet and considering Celsius Energy drink as a supplement rather than a replacement for essential nutrients is advisable.

Why Does The NCAA Ban Celsius?

The NCAA bans Celsius energy drink due to its inclusion of guarana extract, which is a substance that the NCAA completely bans. Guarana is a stimulant that increases central nervous system activity and can enhance athletic performance and give an athlete a competitive advantage over competitors. (Source)

Despite little scientific data to support these uses, student-athletes often turn to guarana and caffeine if they struggle to balance extremely busy schedules as full-time students with athletic duties that include daily team functions.

The NCAA has strict regulations to keep athletes safe and healthy, and they provide an updated list of banned substances that student-athletes are not to consume every school year. The ban on Celsius reminds college athletes to be aware of what they are consuming and to ensure that they are not at risk of failing a drug test given by the NCAA.

Does Consuming Celsius Energy Drink Lead To Dehydration?

Consuming Celsius energy drinks can potentially lead to dehydration. While the company’s website touts that their drinks contain no sugar, high fructose corn syrup, or artificial preservatives, colors, or flavors, they do contain caffeine, a diuretic that can cause increased urination and loss of fluids from the body.

The settlement requires Celsius to modify its advertising and labeling to remove the “No Preservatives” claim.

How Much Caffeine Is Too Much?

The amount of caffeine considered too much varies from person to person, as factors such as age, weight, and overall health can affect how the body metabolizes caffeine.

It is essential to be mindful of your caffeine intake and how your body reacts to it. If you are experiencing negative side effects, it may be time to cut back on your caffeine consumption.

Consuming Celsius Energy Drink every day is possible, but it may not be entirely safe.
