What You Should Know
Celsius is an energy drink that claims to raise metabolism by up to 12% and boost energy levels for 3 hours with their natural, smooth blend of antioxidant rich ingredients, including Green Tea Extract, Biotin, Guarana Seed, and Calcium. Sold in popular store such as Kroger’s and Walgreens, Celsius touts itself as a cheap, flavored drink that claims to keep dieters alert, focused, and slim by burning 100 calories per bottle. Though it does not claim to be a diet supplement, it does claim to be the perfect drink for boosting energy levels during the day.
Although a diet is the best way to boost the metabolism and stay alert, turning to an energy drink may help dieters when energy levels are running low. It is vitally important that they pick the right drink with provable benefits, however, and an affordable price tag. Celsius may deliver on some key points.
Ingredients
According to Celsius, their drink contains Calcium, Chromium, Vitamin C, Vitamin B, Biotin, Riboflavin, Niacin, Guarana Seed, Green Tea Leaf Extract, and Ginger.
Product Features
Celsius focuses on including natural ingredients instead of synthetic ingredients, and some ingredients may legitimately boost energy levels. Green Tea Leaf Extract and Guarana Seed are both sources of caffeine, and the type of caffeine contained in both sources is scientifically-proven to be gentler than straight Caffeine. This type of caffeine stimulates the central nervous syndrome to halt fatigue and causes a less harmful “energy crash” when the effect wears off. Green Tea Extract also contains chemicals that stimulate the metabolism, and sipping two or more cups of this tea may result in increased metabolism. This may be the source of Celsius’s claim that it may stimulate the metabolism.
Celsius’s other ingredients do not contain any provable dietary benefits, but it may provide nutritional benefits. Calcium is important in any diet and some studies show it may help dieters lose weight, but it is best digested from natural, organic forms, such as yogurt or milk.
It does appear Celsius does contain some ingredients which may boost energy levels and the metabolism, but all sources have a better effect if taken in natural form. Green Tea tends to work the best in its natural form, for example, and its extract form is notably less effective.
Advantages
- Contains Green Tea Extract, which may increase the metabolism in larger doses.
- Contains natural ingredients which do not have any major side effects.
Disadvantages
- Ingredients have more potency in natural, non-extract form.
- Its main ingredients do not have any notable dietary benefits.
- Not intended for use as a diet supplement.
- May cause jitters and trouble concentrating. (See reader comments.)
Conclusion
Celsius is a natural drink that claims to boost the metabolism and energy, and its ingredients may contain some of these properties. Depending on a diet drink to help boost these levels may become addictive, however, and obtaining these benefits from natural sources may offer stronger results.

How much caffein is in each can? The literature printed on this product is very vague.
Thank you.

Worst energy drink EVER. So, I took this drink thinking it would give me that extra boost of energy I need without the crash. Now, prior to drinking Celsius I was averaging atleast two cups of coffee per day, so I wasn’t concerned when I saw the caffeine amount per drink (200mg). Once I drank Celsius, I immediately felt jittery which I felt was odd, considering how much caffeine I drink per day. That wasn’t the scary part. My vision then became BLURRED, and it became extremely hard to concentrate or function doing simple activities that I do everyday! I then did some research, and the substitute for sugar they put in the drink called ASPARTAME has the most frightening side effects I have ever seen! No wonder this drink hasn’t been FDA approved!! This just a blurb from amazon.com. READ IT. STUDY IT. DO NOT DRINK THIS DRINK!!
The components of aspartame can lead to a number of health problems, as you have read. Side effects can occur gradually, can be immediate, or can be acute reactions. According to Lendon Smith, M.D. there is an enormous population suffering from side effects associated with aspartame, yet have no idea why drugs, supplements and herbs don’t relieve their symptoms. Then, there are users who don’t ‘appear’ to suffer immediate reactions at all. Even these individuals are susceptible to the long-term damage caused by excitatory amino acids, phenylalanine, methanol, and DKP.
Adverse reactions and side effects of aspartame include:
Eye
blindness in one or both eyes
decreased vision and/or other eye problems such as: blurring, bright flashes, squiggly lines, tunnel vision, decreased night vision
pain in one or both eyes
decreased tears
trouble with contact lenses
bulging eyes
Ear
tinnitus – ringing or buzzing sound
severe intolerance of noise
marked hearing impairment
Neurologic
epileptic seizures
headaches, migraines and (some severe)
dizziness, unsteadiness, both
confusion, memory loss, both
severe drowsiness and sleepiness
paresthesia or numbness of the limbs
severe slurring of speech
severe hyperactivity and restless legs
atypical facial pain
severe tremors
Psychological/Psychiatric
severe depression
irritability
aggression
anxiety
personality changes
insomnia
phobias
Chest
palpitations, tachycardia
shortness of breath
recent high blood pressure
Gastrointestinal
nausea
diarrhea, sometimes with blood in stools
abdominal pain
pain when swallowing
Skin and Allergies
itching without a rash
lip and mouth reactions
hives
aggravated respiratory allergies such as asthma
Endocrine and Metabolic
loss of control of diabetes
menstrual changes
marked thinning or loss of hair

Other

FYI Aspartame is in every diet drink and other diet products like fat free yogurt & they are FDA approved. Aspartame is definitely not healthy for you, however i wanted to point out that, that chemical was not holding up the approval from the FDA.

I asked about the caffine and it is only the natural caffine found in the green tea in the product (not much in other words).
[Reply]
Does anyone know if this is available in Canada and where it can be found?

Does anyone know if this is available in Canada, and if so, where?

I like celsius,it really works and it does’t give you jitters or crash.
[Reply]
Is it recommended to drink no more than 3 celsius drinks a day? I was just wondering if there was a suggested “limit” or not. THxx
[Reply]
do you need to exercise everytime you drink this? or can you just drink one every day?
[Reply]
This product doesn’t work. The product info even tells you that you must diet and exercise. The so-called benefit is only 100 calories per can which would require 35 cans to produce one pound of fat lost. Bogus product using caffeine to stimulate you. It is mildly addictive, so take a pass on Celsius.
[Reply]
well duh, you can’t sit on ur a$% and eat pizza and lose weight. But it boosts your metabolism from all the healthy ingredients which will make u burn more calories and since it is natural I don’t see how it could be addictive.
[Reply]
Cocaine and nicotine are natural. You probably can’t see how they are addictive either. Arsenic, Cyanide, and Hemlock are natural, too. The only reason they aren’t addictive is that you die after the first use most of the time. There are few healthy ingredients in Celsius, and many have side effects that are disturbing. Please understand a little about what boosts metabolism. Let’s use smoking as an example. The damage each cigarette does to the human body is so harmful that the body’s natural defenses have to go into overdrive to try to repair the damage. While your body can never repair all the damage, the flurry of activity that this fight causes takes up a lot of energy or calories. The resulting boost in metabolism from the body’s fight against the damage done by cigarettes is small consolation considering the smoker’s increased exposure to heart disease, stroke, more than eleven types of cancer, emphysema, etc. So, you can keep a small amount of fat off your ass by smoking. Your pallbearers will be grateful that your coffin is easier to carry. Celsius certainly not in the destructive league with cigarettes, but there is no proveable increase in metabolism from it. Caffeine does not give energy. It may cause nervous physical motion which would indeed boost metabolic rate by a microscopic degree. What price are you willing to pay for a tiny–perhaps negligible–step up in calorie expenditure? Exercise is the ONLY healthy step one can take to boosting metabolism without causing unacceptable side effects. Caffeine is not a serious offender, but neither is it completely harmless. There is no substitute for a good night sleep to earn a restful state of wellness, nor is caffeine a replacement for exercise to boost metabolic rate. You won’t find thinness in an aluminum can. So, Janine, in answer to your comment, Celsius does not safely boost metabolism, and it does not have healthy ingredients. Spend your money on a good pair of walking shoes instead. You can’t safely raise your body’s rate at which it uses energy (calories) without exercise. Celsius is distracting you from the one solution at your fingerprints. Like so many other products today, it is a scam.

[Reply]
It’s awesome! It’s healthy, gave me energy and tastes great plus it is only ten calories so if u are trying to lose weight u can replace your high calorie juices and sodas with these! They even have cola flavor that tastes like coke! LOve it!
[Reply]
My Celsius says “no Aspartame”.
[Reply]
is it bad that i drank 3 of them today and im 14 years old? how do we know this product really works?
[Reply]
it’s 4AM i can’t sleep…
[Reply]
Hi Courtney,
I hope you finally got some sleep! Perhaps it will be better to have just ONE can in the mornings. Sleep is as important to good health as weight control.
If you are concerned about your weight, you are at a great age to lose weight through exercise. I lost a lot of weight at 14 just by dancing for 1/2 an hour every night in my bedroom. If you focus on eating mostly fresh fruits and veggies and drinking water, your complexion should be gorgeous as well.
Best wishes!
