Celsius makes and sells energy drinks, which serve as a refreshing alternative to coffee for anyone looking for a mid-afternoon caffeine fix.

Marketed as a fitness supplement that’s packed with natural ingredients such as green tea and guarana extract, Celsius’ “Live Fit” slogan appeals to athletic-minded consumers who believe it is healthier than alternatives such as Red Bull and Monster. Its drinks are vegan-friendly and contain no sugar or carbohydrates.

Numerous scientific studies have claimed its drinks have thermogenic properties, meaning they boost your metabolism and cause your body to burn more calories than it would with exercise alone. Celsius was founded as the world’s first negative-calorie drink, which reportedly can burn from 100 to 140 calories per bottle. However, this is a debatable topic and the FDA does not have an official opinion on the claims. The core Celsius drink comes in 27 different flavors, with another 6 Essentials flavors intended for workouts and another 9 On the Go flavors that are dry powder packets to mix with water. The average grocery store now carries 20 unique Celsius SKUs and has devoted 35% more shelf space to the drinks than they did last year.

Celsius did $1.3 billion in total sales during fiscal 2023 and has 765 employees; recognizing an impressively-high $1.7 million in revenue per employee. It was founded in 2004 and is headquartered in Boca Raton, Florida.
