This week, I obsessed over every aspect of the weight-loss drink Celsius, so we examined the ingredients, side effects, clinical research and quality of customer service. We scoured hundreds of consumer comments and reviews. We then refined and summarized to give you the info you need.
Substitute Celsius with a proven fat burner such as Leptigen
for better results.
What You Need to Know
To start off with, Celsius is a weight-loss and energy drink that has green tea, guarana seed extract, ginger root, B-vitamins and chromium. When you consume one per day, it will supposedly help you lose weight. A benefit is you can consume it on the go.
The product, introduced in 2004, uses some natural ingredients, which is a good choice. You can buy the drink at retail stores, but you can’t order it from the official website. We like that there are some people who’ve had positive experiences and the company has been around a while, but read on…
Side Effects – “Feeling a Bit Shaky?”
The first concern we have involves Celsius side effects, which may include jitteriness and stomach concerns. “Energy drinks contain stimulants, that’s often the nature of the formula,” offers our Research Editor. “It’s how much is included that can mean the difference between a good punch and a jolt that doesn’t feel so positive.”
“Once I drank Celsius, I immediately felt jittery which I felt was odd,” said a consumer of Celsius ingredients.
“I was suffering headaches, muscle twitches and even a flutter in my chest,” reported another.
Side effects are different from one person to the next. According to one dieter, nothing but good things happened, “I have no shaky afer effects, no queasy stomach.”
We also found one that said, “Tastes nice and does not make you jittery.”

Taste – “Not What Was Expected”
According to some customer comments, the taste of Celsius wasn’t right. Some commented that the beverage tasted flat. “To me it tasted flat and artificial and all around not good,” said a customer.
“This tastes nothing like mango or peach (not to us). I can’t even describe the taste,” explains a dieter.
“So nasty tasting had to dump the majority of the cans down the sink,” commented a user.
Products like Celsius will always have some consumers who like them and some who don’t. One person who had a positive experience said, “It tasted kind of weird at first but I got used to it real quick and now I look forward to drinking them.”
Another shared, “It has a good taste and helps to boost your energy.”
Our research shows it takes just a small part of a weight-loss program, like side effects, to hamper chances of long-term success. If Celsius leaves dieters feeling jittery, they may not continue using the product.
The Science – “Clinical Evidence?”
There are links to clinical studies supporting certain claims made by Celsius. What interested us the most was the “Weight Loss Effect in Overweight Women” paper. This one doesn’t come with a link to the journal where it was published. Even better is the participants “reported to a training facility” on workout days. The average dieter doesn’t have access to this type of exercise routine. The science is lacking with Celsius and at DietSpotlight that’s what’s most important. If there’s no proof a product works, there’s no real reason to spend the money.
The Bottom Line – Does Celsius Work?
Well now, the verdict is in on Celsius, so what did we find? There are positives, including a few good customer comments and the fact that it has natural ingredients, but we have some reservations because the research performed was not realistic for the average dieter. We are also concerned about potential side effects and bad taste.
If you’d like to slim that waistline, we recommend going with a product that with ingredients backed by published clinical studies that aren’t there to make you feel worse for the wear.
Among the best products we’ve seen in 2016 is one called Leptigen. The formula consists of a four-ingredient proprietary blend, shown in published scientific research to help ignite fat loss and enhance metabolism. We found no mention of adverse side effects and customer reviews report excellent results.
Additionally, the makers of Leptigen have confidence in the product so they’re offering a Special Trial Offer, quite a benefit.

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.
According to Celsius, their drink contains Calcium, Chromium, Vitamin C, Vitamin B, Biotin, Riboflavin, Niacin, Guarana Seed, Green Tea Leaf Extract, and Ginger.
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.

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.

Green tea is produced from the Camellia sinensis plant. It is prepared through steaming instead of fermentation, which is why is it considered healthier than black and oolong tea.
What Is It Supposed To Do?
Green tea is apparently useful for mental alertness, thinking, cancer, depression, liver disease, stomach issues, athlete’s foot, and much more.
Research done in Scotland has proved green tea can be quite beneficial for weight-loss. In their study, published in Clinical Nutrition, researchers noted that, “12 weeks of treatment with high-dose green tea extract resulted in significant weight loss, reduced waist circumference, and a consistent decrease in total cholesterol and LDL plasma levels without any side effects or adverse effects in women with central obesity.”
Guarana Seed Extract
Guarana got its name from the infamous Guarani tribe, when they used certain seeds to brew a special drink. Now, the same guarana seeds are still used for medicines.
What Is It Supposed To Do?
Guarana seed extract is used as ailments for many health problems, including low blood pressure, fatigue, pain, heart stress, and more.
In 2006, a study was published in the European Journal of Medical Research regarding the effects of guarana. In their conclusion, the researchers stated, “A change in some outcome measures like: weight, BMI failed to produce significant difference between groups.” Additionally, this was measured through the use of a supplement containing other herbal supplements.
Ginger is a plant originating in warmer areas of Asia, Africa, and South America. It is often used as a spice, as well as various medicines in the Middle East.
What Is It Supposed To Do?
Ginger is known to help reduce inflammation and nausea. It has also been marketed as a laxative.
A recent study was published in the European Journal of Nutrition evaluating the effects of ginger on weight loss. In the conclusion of the article, researchers stated that, “In conclusion, our findings demonstrate a minor beneficial effect of 2g ginger powder supplementation for 12 weeks on weight loss and some metabolic features of obesity.”
Chromium is an essential trace mineral founds in various foods and supplements. This should not be confused with hexavalent chromium, which is a known toxin.

Chromium is thought to help normalize blood sugar levels by controlling the use of insulin in the body.
In an article from the University of Maryland Medical Center, there is discussion about the possible benefits of chromium in weight-loss, saying, “Studies have been mixed, with some finding that chromium may help people lose weight and build muscle, and others finding it has no effect.”
