  • CELSIUS Stevia contains 200 mg of caffeine per can.

We recommend consulting with your health care provider if you are concerned that CELSIUS may impact your health.

Q: Is it Safe to Drink CELSIUS Every Day?


A: Yes, it is safe to drink CELSIUS every day.


When combined with other lifestyle factors, drinking CELSIUS each day is safe for most consumers. Those who have adverse reactions to CELSIUS likely have pre-existing health conditions, are drinking too many cans of CELSIUS per day, or are consuming too much caffeine in general.

We recommend consulting with your health care provider if you are concerned that CELSIUS may impact your health.

How Many Cans of CELSIUS is Too Many?



We recommend no more than (2) 12 oz cans/(2) servings per day, and that you follow the daily serving recommendations for all other CELSIUS products.

The FDA advises that drinking up to 400 mg of caffeine – the equivalent to two 12oz cans of CELSIUS – is safe for most individuals. However, everyone metabolizes caffeine differently, which means that caffeine sensitivity varies from person to person (FDA, 2018).

If you are new to energy drinks, we recommend drinking no more than one CELSIUS in a 24-hour period. If you have a high tolerance to caffeine, we recommend no more than two CELSIUS cans every 24 hours.

Q: Can Drinking CELSIUS Cause Kidney & Liver Damage?



CELSIUS is not known to cause liver or kidney damage when it is consumed as recommended. Those who have experienced adverse effects from drinking CELSIUS are likely drinking more than recommended or have existing liver or kidney conditions.

We recommend consulting with your health care provider if you are concerned that CELSIUS may impact your health.

Essential Facts

CELSIUS® and the NCAA Rules

Since its founding in 2004, CELSIUS fitness drinks have been enjoyed by the most elite professional and collegiate athletes in sports all over the world. With its clinically proven formula, CELSIUS has solidified its place as a pioneer in the rapidly growing performance energy sector.

Some collegiate athletes may have questions about whether one ingredient in CELSIUS products – caffeine derived from guarana extract – raises any issues under NCAA rules.

What is the Guarana Ingredient in CELSIUS?
  • The caffeine in CELSIUS is sourced in part from guarana extract, a safe, plant-derived form of caffeine.
  • According to the Drug Free Sport AXIS, which handles the NCAA’s authoritative review of label ingredients, guarana “is not specially banned by the NCAA” but is merely an example of a source of caffeine.
  • The NCAA does not differentiate between sources of caffeine, such as coffee beans, tea leaves, soft drinks, a bar of chocolate – or guarana.

Caffeine appears on the NCAA’s Banned Substance List.1 Does that mean the NCAA Drug Testing Program bans athletes from consuming all caffeinated products, including those like CELSIUS?
  • No. It is important to understand that the NCAA Drug Testing Program does not consider an athlete to test positive for caffeine if consumed responsibility.2
  • To give perspective, for athletes weighing just 110 pounds, the International Society of Sports Nutrition estimates they’d have to drink over 500 mg of caffeine within several hours just prior to competition to test positive — and even more caffeine for athletes weighing more.4
  • According to a publication by the NCAA’s Sport Science Institute, 500 mg of caffeine is equivalent to “six or eight cups of brewed coffee, two to three hours before competition.”3
  • CELSIUS contains 200 mg of caffeine per can and recommends that consumers not drink more than 2 per day (or for CELSIUS HEAT®, 1 per day). These recommended servings will test under the NCAA’s caffeine limits for most athletes.*

* Individual test results depend on metabolism and other caffeine consumption on the day of competition. All athletes must ensure that they are educated on the health effects of any energy drink and confirm with their athletic departments and universities or colleges that there is no risk to eligibility by consuming them.5

Has any NCAA athlete ever been declared ineligible to compete due to consuming CELSIUS?
  • No. Consuming CELSIUS has never been reported as the cause of any NCAA athlete’s ineligibility to compete at the collegiate level.

The Banned Substances Control Group (BSCG)—a leading expert on dietary supplements and drugs in sport—analyzed the NCAA’s rules around caffeine and guarana at CELSIUS’s request.
