Most Caffeinated Drink in the World

The Redline Extreme Energy Drink has the most caffeine per fluid ounce. This drink contains 316 milligrams (mg) of caffeine in an 8-ounce package, so  39.5 mg of caffeine are in each ounce. The next in line is the Redline Princess, which comes in an 8-ounce container and has 300 mg of caffeine. This amount of caffeine works out to about 37.5 mg per ounce.

How Does the Caffeine in Redline Extreme Compare to Coffee?

The average cup of home-brewed coffee has about 95–140 mg of caffeine per 8 ounces, so it’s only about half as potent as the Redline Extreme Energy Drink. However, if you get your coffee from Starbucks or another chain, some of the varieties can be a bit more potent, like the Starbucks Dark Roast, which has about 190 mg of caffeine in an 8-ounce cup. People also tend to get large drinks from these chains, and these will have more caffeine. It’s popular to add a shot of espresso too, which contains 64 mg per ounce.

Do Other Drinks Have More Caffeine Than Redline Extreme?

Yes. Redline Extreme is a commercially available 8-ounce beverage that has the most caffeine per ounce. However, several drinks are available that contain more caffeine, including other energy drinks, like the Hyde Extreme, which has 400 mg of caffeine in a 12-ounce container. You get more caffeine, but since the container is larger, you only get 33.3 mg per ounce. Other examples of this include large coffee beverages, some of which can have nearly 500 mg of caffeine, like the Starbucks Blonde Roast, which has 475 mg of caffeine in the 20-ounce cup, but only 23.75 mg per ounce.

Starbucks also allows you to customize drinks, so you can add espresso to your coffee. Technically, you can add four shots or more of espresso to an 8-ounce coffee to make it stronger than Redline Extreme, but it isn’t something that you choose off the menu. The 5-Hour Energy Shot contains 200 mg of caffeine in a 1.93-ounce package, meaning you’re getting more than 103 mg per ounce, but it isn’t a drink because it is so small. You can also purchase liquid caffeine, which has 235 mg per ounce, but this is also not a drink and can be unsafe without mixing it with something else to dilute it.

How Much Caffeine Is Safe to Consume?

It’s important to remember that caffeine can be hazardous to your health. Too much can lead to sleepless nights, anxiety, tremors, increased heart rate, high blood pressure, and even kidney stones. Most experts recommend limiting your caffeine consumption to less than 400 mg each day to maintain good health. It’s also a good idea to drink plenty of water when you consume a large amount of caffeine because it is a powerful diuretic that can leave you dehydrated.

Redline Extreme is the most caffeinated drink in the world, and it is a great choice if you need a fast and powerful boost of caffeine. However, since a single 8-ounce can of Redline Extreme or its sister, Redline Princess, can get you ¾ of the way to the recommended limit, it can be potentially dangerous. You will need to monitor your other caffeine sources throughout the day carefully, so you don’t overindulge and create health problems for yourself.
