What Is the Strongest Energy Drink?

The 5-Hour Energy brand is the strongest energy drink in the world in terms of the amount of caffeine that it contains per ounce. The regular version of the energy drink contains 200 milligrams of caffeine in a little under 2 ounces (1.93), while the extra-strength version increases the amount of caffeine to 230 milligrams. At 99–113 milligrams of caffeine per ounce, the 5-Hour Energy drink is easily the strongest brand globally.

What Is the Second-Strongest Energy Drink?

Redline energy drinks are currently the second-most potent energy drinks available to consumers in the United States. A bottle of Redline contains 8 ounces of the beverage and has 316 milligrams of caffeine. This amount of caffeine is more than what you will find in most other brands, and those often contain 16 or even 20 ounces of beverage. While it’s not hard to get more caffeine in certain coffee drinks offered by big chain shops, those drinks are often much larger. At 39.5 milligrams of caffeine per ounce, Redline is the second-strongest energy drink in the world.

Drink Size in Ounces Caffeine in Milligrams
5-Hour Energy Extra Strength 1.93 230
5-Hour Energy 1.93 200
Redline 8 316
Coke 20 33.3
Diet Pepsi 20 59
Morning Coffee 8 95–140
Tea 8 45
Dunkin’ Regular Coffee 14 210
Starbucks Regular Coffee 16 260

Are 5-Hour Energy Drinks Safe to Drink?

Yes. As long as you are not sensitive to caffeine and limit your consumption to one per day, you should not experience any serious health problems. Most experts recommend limiting your caffeine intake to less than 400 milligrams per day to avoid health problems. Two regular strength 5-Hour Energy shots will put you right at the limit, so you can get into the danger zone if you consume any other caffeine, such as by drinking soda, coffee, or eating chocolate.

What If I Consume Too Much 5-Hour Energy Drink?

If you consume more than two 5-Hour Energy drinks per day, you can accidentally overdose on caffeine. Most people will notice trembling in the hands, and you may also start to feel restless or anxious. An inability to fall asleep is another reported symptom of drinking too much caffeine. More sensitive people might get a headache or experience diarrhea, increased thirst, and even an increased body temperature. If you notice vomiting, chest pain, confusion, or convulsions, seek out medical treatment.

While it’s possible to get more caffeine in a single beverage from several different sources, none of them offer more than 100 mg of caffeine per ounce, which 5-Hour Energy does. The Redline is a close second, and a single 8-ounce bottle has more caffeine overall (316 milligrams), but you need to drink more of it. Either will get you moving throughout your day and may even help you perform better at the gym, but it’s easy to overdose on caffeine while consuming these drinks, especially if you are a regular coffee drinker.
