For many of us, the word Slurpee conjures up summer afternoons, sweltering temperatures, and hot pavement as we made our way to the local 7-Eleven for a refreshing treat to enjoy while we played with our friends. In 2020, 7-Eleven announced an energy drink Slurpee that contains caffeine.

So, exactly how much caffeine is in a Slurpee? The average amount of caffeine in a Slurpee is 30 milligrams (mg) per 12-ounce cup. If you have been wondering about caffeine amounts in your favorite Slurpee and even how the Slurpee stacks up against the other leading energy drinks on the market, we’ll be discussing that and more below.

Comparing Slurpee Caffeine Content (Across Flavors)

Most Slurpees have around 30 mg of caffeine per 12-ounce cup. However, that depends on the flavor of the caffeinated Slurpee you’re ordering. We’ll list the caffeine content of a few of them below.

Quake Energy Berry Blast 69 mg
Pepper Slurpee 23 mg
Dew Slurpee 30 mg
Coca-Cola Slurpee 22 mg

As you can see, if the soda version has caffeine, so does the Slurpee, though the caffeine is slightly less than a traditional soda.

Comparing Slurpee Caffeine Content to Other Energy Drinks

Keeping in mind that your normal Slurpee has around 30 mg of caffeine per 12-ounce cup, we’ll compare the Slurpee to other leading energy drinks on the market today.

Slurpee 30 mg per 12-ounce cup
Bang Energy Drink 300 mg per can
Starbucks Triple Shot 225 mg per shot
Monster Energy 160 mg per can
Red Bull 80 mg per can

As you can see, Slurpee has quite a bit less caffeine than the other leading energy drinks on the market today. However, it’s important to note that on top of the caffeine, Slurpees contain quite a bit of sugar, around 24 grams, and a total of 90 calories, so that’s something you need to be careful of.

Where Can You Buy Slurpees?

You can, of course, find Slurpee’s at your local 7-Eleven and almost any convenience store in your area. There are even a few grocery stores that sell the beverages as well.

What Is a Slurpee?

A Slurpee is a frozen carbonated drink under 7-Elevens’ exclusive brand name. While you can get Slurpee’s at other convenience stores, they will be under another name. These sweet frozen drinks are perfect for a hot summer’s day.

While you can get Slurpees that have no caffeine for the kids, they now have caffeinated Slurpees for the adults, making them a great energy drink to give you that shot of caffeine you need to get through the day.

Recommended Allowance of Caffeine Daily

While there is very little caffeine in a Slurpee on average, it is essential to remember that the recommended daily allowance of caffeine is only 400 mg, which some of the energy drinks on our list almost reach with one can.

While a Slurpee certainly doesn’t contain an extreme amount of caffeine, it might not be the best choice for you if you have a caffeine sensitivity. In our next section, we’ll give you some ideas for ways to get the energy you need to make it through the afternoon without caffeine.

Alternatives to Caffeine for Energy

Too much caffeine isn’t good for anyone, whether coffee or energy drinks. It can make you jittery, give you insomnia, and even cause a rapid heart rate in many people. So, what can you do to get that burst of energy you need midday to make it through? We’ll give you a few of our top choices of caffeine alternatives below.

Certain Teas

Green, black, and peppermint teas are great beverages to get energy when you need to keep going. Of course, they aren’t going to give you that burst of energy that caffeine does, but they won’t provide you with the crash that caffeine does, either.

On top of that, herbal teas are a great way to relax after a hard day’s work as well. Here are a few other excellent choices for energy without caffeine that you might want to try.

  • Macha
  • Cordyceps
  • Nuts
  • Ginseng
  • Carob
  • Rodiola
  • B vitamins
  • Chicory Root Coffee

If you are caffeine-sensitive or want less caffeine in your diet, these alternatives are ideal. While you might not get the instant results caffeine gives you, you’ll have more energy.

Wrap Up

Slurpees are tasty, refreshing treats that most of us remember having when we were kids. Now, caffeinated Slurpees will also help you get through that mid-afternoon crash. With 30 mg of caffeine, the frosty beverage is an excellent choice for those that prefer a lower level of caffeine.

However, if you have caffeine sensitivity, it might be best to talk to your doctor before trying this product. Even if you can’t have caffeine, many refreshing Slurpee flavors have no caffeine and still taste amazing, and you won’t miss out on the delicious frozen drinks altogether.
