Celsius stands out from most energy drinks by citing an actual published clinical study on the finished product — a genuine rarity in this category. This Celsius review checked what that study found, and weighed it against the drink’s 200mg caffeine content.
How We Researched This Celsius Review
This Celsius review checked the published clinical trial on Celsius specifically, the research behind its core ingredients (green tea, guarana, ginger, chromium), and real pricing across retailers.
Celsius Review: What Is It?
Introduced in 2004 by former GNC chairman Greg Horn, Celsius is a thermogenic energy drink sold across dozens of flavors and formats (Originals, Heat, On-the-Go powders), built around green tea, guarana, ginger root, chromium, taurine, and 200mg caffeine per 12oz can — sugar, aspartame, and high-fructose-corn-syrup free.
What the Research on Key Ingredients Shows
- Canadian Pharmacists Review: a review of 14 randomized controlled trials found green tea helped participants lose up to 3.5kg more than controls over 12 weeks.
- European Journal of Nutrition: 2g/day of ginger for 12 weeks showed a “minor beneficial effect” on weight and metabolic features of obesity.
- Phytotherapy Research: guarana may fight obesity by targeting brown fat tissue specifically.
The Study Behind the “Clinically Proven” Claim
Unlike most energy drinks, Celsius has an actual published trial behind it: the Journal of the International Society of Sports Nutrition found “pre-workout consumption of Celsius enhances the benefits of chronic exercise on body composition and cardiorespiratory fitness” — a genuine, product-specific result, not just ingredient-level extrapolation.
Side Effects
At 200mg caffeine per can, reported effects include jitters, headache, nausea, upset stomach, and sleep disruption — the company specifically recommends avoiding it within five hours of bedtime. Anyone caffeine-sensitive should account for the full dose before drinking.
Cost
A 12-pack runs $20–$35 through Amazon and similar retailers; powder packets average around $12. A 100% money-back guarantee applies, though some retailers cap the window at 15 days given the product’s liquid form.
Who Celsius Actually Makes Sense For

This fits people who want a sugar-free, artificial-ingredient-free energy drink specifically for pre-workout use, and who tolerate 200mg of caffeine well. It’s a poor fit for anyone caffeine-sensitive or already consuming regular coffee/tea, and it’s not FDA approved as a weight-loss product — it should be treated as a supplemental aid alongside diet and exercise, not a standalone solution.
Celsius Review: Frequently Asked Questions
Is Celsius actually backed by clinical research?
Yes — unusually for this category, a published study found pre-workout Celsius consumption enhanced exercise’s effects on body composition and fitness.
How much caffeine is in Celsius?
200mg per 12oz can — a meaningful dose worth factoring against other caffeine sources in your day.
Is Celsius sugar-free?
Yes — most varieties use no sugar, artificial preservatives, or high-fructose corn syrup.
Celsius Review: The Bottom Line
Celsius genuinely stands out in the energy drink category for having an actual clinical study behind the finished product, not just ingredient-level research — a real point of differentiation. The 200mg caffeine dose is substantial enough to require real awareness of your total daily intake. This Celsius review found a legitimately better-evidenced option than most competitors, best used as a workout supplement rather than a standalone weight-loss tool.
