In the last few years, there’s been an absolute deluge of energy drinks on the market. Today, energy drinks make up nearly a third of the soft drink beverage industry and are hugely popular among teens, students, truckers, and anyone living a busy lifestyle. That includes one of the newer energy drinks on the scene, Rockstar Xdurance. Rockstar Xdurance is made for anyone needing a hard-hitting dose of caffeine to keep them awake, focused, and ready to tackle the task. How much caffeine is in Rockstar Xdurance? You’ll find a whopping 300 milligrams of the stuff in every 16-ounce can, nearly 19 milligrams per ounce. Read on to discover more about how the caffeine in Rockstar Xdurance compares to other energy and coffee drinks!
How Much Caffeine Do Energy Drinks Contain?
You might be surprised at how much caffeine is in one can of Rockstar Xdurance, especially considering that an 8-ounce cup of brewed coffee contains about 95 milligrams. In other words, a can of Rockstar Xdurance equals drinking three cups of coffee. However, Rockstar Xdurance doesn’t contain the most caffeine you'll find in an energy drink, and several have 40 to 60 milligrams more per can. There are also several energy drinks with less caffeine than Rockstar Xdurance. It depends on the energy drink manufacturer and what they put in their respective formulas, which vary widely from one to the next. Red Bull, one of the most well-known energy drinks and an icon in the industry, has roughly a third of the caffeine of Rockstar Xdurance at 80 milligrams.

All About Energy Drinks
An energy drink refers to any drink formulated to provide a quick burst of energy to the drinker. Most energy drinks provide their energy by putting caffeine in their formula, although some also rely on sugar for energy, and others use taurine and other natural stimulants. Most energy drinks contain at least as much caffeine as a cup of regular, brewed coffee, but some include a much higher amount. Rockstar Xdurance, for example, has 300 milligrams of caffeine, which is approximately equal to 3 cups of coffee. What’s also different about energy drinks is that they’re made to be enjoyed cold and drank quickly. For example, while it might take 30 to 40 minutes or more to drink three hot cups of coffee, you can drink an entire energy drink in mere seconds. Because of this, the caffeine gets into your body faster.
Fun Facts About Energy Drinks
- The federal government once forbade Monster Energy from putting too much caffeine in their drink formula. They had their energy drink reclassified as a “supplement” to get around the ban.
- Because they are now categorized as supplements, the FDA doesn’t have the authority to regulate energy drinks.
- In ancient Rome, a drink called Posca was popular and supposedly gave the drinker an energy boost. It was typically given to soldiers.
- Red Bull was banned in Canada until 2004.
- Most energy drinks have about half the caffeine of a regular coffeehouse coffee.
- All leading energy drinks voluntarily disclose the amount and source of caffeine in their drinks.
Final Thoughts
As we’ve seen, Rockstar Xdurance has a very high amount of caffeine compared to regular coffee and many energy drinks. At 300 milligrams in every 16-ounce can, Rockstar Xdurance has about three times the amount of caffeine as a regular cup of brewed coffee. That number, however, is still less than the US RDA of caffeine, which is 400 milligrams. We hope you enjoyed this closer look at the caffeine content of Rockstar Xdurance and that it helps you make the best choice on your next energy drink purchase. See Also:
