How Many 5 Hour Energy Drinks Can You Drink In A Day?

5 Hour Energy Drink

Need a quick energy boost but don’t feel like downing a 16 fl.oz energy drink?

5 Hour Energy Shots have you covered, delivering all the potential of an energy drink in a 1.93 fl.oz, sugar-free package.

But how many can you drink in a day? Is it safe to consume every day? Or should you only drink it every other day or once a week?

In short, 5 Hour Energy Shots are a great pick-me-up and will help in getting you through those late-night crunch sessions or an afternoon energy slump.

However, they don’t taste great, so it’s not something you can enjoy casually and they probably aren’t right for everyone.

For a more detailed review, read on to find out everything you need to know about 5 Hour Energy Shots, from ingredients to taste, and if the drink is actually as good as it seems.

Let’s get started…

5 Hour Energy Drink Nutrition Facts

Firstly, here’s a table comparing the nutritional value of 5 Hour Energy Drink with some of its competitors.

The ingredients contained in 5 Hour Shots and comparable energy drinks.

Overall, the first thing you probably notice is the size of 5 Hour Energy Shots, which are a lot smaller than regular energy drinks (1.93 fl.oz vs. the usual range of 8.4 to 16 fl.oz).

This means that, while you can usually take anywhere between 10 to 45 minutes to finish a regular energy drink, you can be done with a 5 Hour Energy Shot in mere seconds.

Due to how quickly you can down a shot, its effects on your body will show almost instantly (when it gets absorbed into your system), instead of a gradual ramp-up like most other energy drinks.

For context, it’s basically the same as having a shot of whiskey instead of nursing a beer for half-an-hour; the former is a lot more likely to get you buzzing sooner.

So if you’re an energy drink enthusiast who’s into the casual enjoyment, taste and hydration aspect of energy drinks, 5 Hour Energy Shots might not be the best choice for you.

On the other hand, if you just want a quick and instant boost to get your work done, 5 Hour Energy Shots is probably right up your alley.

How Much Caffeine Is In a 5 Hour Energy Shot?

Each serving of 5 Hour Energy (1.93 fl.oz) has 200mg of caffeine.

Oddly enough, for a caffeinated product that boasts 5 hours of energy, 5 Hour Energy Shots aren’t actually the strongest energy drinks in the market, as brands like Reign and Bang have up to 300mg of caffeine.

However, as stated earlier, 5 Hour Energy Shots have a lot less liquid content in them than most other energy drinks.

So from a caffeine per volume perspective, 5 Hour Energy has roughly 103mg per fl.oz, while drinks like Reign and Bang have only 18.75mg per fl.oz.

Essentially, it’s a lot of caffeine in a much smaller package, which could explain why its effects are delivered to your body exceptionally fast.

Even if you’re used to caffeinated beverages and have a decent caffeine metabolism, there’s a pretty big difference between having 300mg over 30 minutes and having 200mg in mere seconds.

Even if you’re used to caffeinated beverages and have a decent caffeine metabolism, there’s a pretty big difference between having 300mg over 30 minutes and having 200mg in mere seconds.

So be sure you know what you’re getting into before having a 5 Hour Energy, especially if you’re new to the whole energy drink scene.

For reference, the FDA also recommends you limit your daily caffeine intake to a maximum of 400mg, as any more might lead to a caffeine overdose which can lead notable side effects, namely:

  • Insomnia
  • Anxiousness
  • Increased Heart Rate
  • Digestive Issues
  • Nausea
  • Headaches

But, as long as you only have 5 Hour Energy Shots in moderation and not too often, you should be able to avoid the effects of having too much caffeine in your system.

Does 5 Hour Energy Drink Contain Sugar?

White Sugar

5 Hour Energy Drink doesn’t contain sugar and are sugar-free, but they do contain artificial sweeteners, namely sucralose and acesulfame potassium.

5 Hour Energy Drinks are sugar-free, so they shouldn’t have any negative impact on you from a dietary perspective which is a welcomed plus considering many energy drinks are high in sugar.

Besides that, you also don’t have to worry about a sugar-induced crash after having a 5 Hour Energy Drink since none of its ingredients will actively raise your blood sugar level.

As for the drink itself causing an energy crash due to its ingredients, that’s a discussion for further down the line.

While 5 Hour Energy Drink are free of sugar, they do contain artificial sweeteners, namely, the zero-calorie sweeteners sucralose and acesulfame potassium.

Although I find it pretty strange that sweeteners are included in such a small serving of energy drink, it might just be there to counteract the bitterness of caffeine.

As zero-calorie sweeteners, both ingredients won’t have a nutritional impact on your diet and, while there’s still a lot we don’t know about artificial sweeteners, they have been approved by the FDA.

Hence, as long as you don’t overdo it on the 5 Hour energy shots, you should be perfectly fine from any potential side effects.

B-Vitamin Content in 5 Hour Energy Drink

5-Hour 5 Hour Energy Drinks have a staggering amount of B-Vitamins, with the Vitamin B12 content going up to 20,000% the daily recommended value.

That said, all the B-Vitamins present in 5 Hour Energy Drink are well within their tolerable upper intake level, so there’s not really a risk of overdosing.

Considering B-Vitamins are more nutritious than anything else, the high amount in 5 Hour Energy will help you with a well-rounded diet, but it won’t give you much in terms of energy.

Does 5 Hour Energy Drink Actually Work?

In terms of keeping you awake, 5 Hour Energy does exactly that by mainlining caffeine into your system in a short amount of time, giving you that boost you need as quickly as possible.

Essentially, 5 Hour Energy Shots works through caffeine, a pretty handy stimulant that blocks the adenosine receptors in your brain and prevents the onset of fatigue from setting in.

Caffeine does a lot of great stuff, from improving psychomotor performance to preventing you from falling asleep in the middle of a lecture, so it’s no surprise why coffee and energy drinks are as popular as they are.

If you need an immediate boost, 5 Hour Energy Drink will definitely give you the energy you desire.

Is 5 Hour Energy Drink Bad For You?

As long as you have them in moderation and only when you need to, 5 Hour Energy Drink will give you the boost you need with minimal side effects, and won’t have any serious health consequences.

That said, if you happen to be caffeine-sensitive, I would suggest staying away from 5 Hour Energy Drinks as they deliver a large amount of caffeine to your system fairly quickly.

Besides that, metabolizing 200mg of caffeine in a short period of time also means the effects are more likely to wear off sooner, as compared to having a constant intake of a regular energy drink.

There are also some reports of 5 Hour Energy Drink causing symptoms of crashes, most likely due to the caffeine leaving the system.

So whilst you’re free from sugar crashes, 5 Hour Energy Drink apparently does cause some strain a few hours after having the drink, not from a sugar crash but a caffeine crash.

Apart from that, exceeding two shots of 5 Hour Energy day is a pretty bad idea, and so is mixing the drink with other caffeinated beverages such as coffee, as doing so would definitely risk a caffeine overdose.

Sticking to one 5 Hour Energy Drink gives you better chances of avoiding these side effects.

How Long Does 5 Hour Energy Drink Remain In Your System?

5 Hour Energy Drink can stay in your system for around 12 hours, depending on your caffeine tolerance and body size.

The effects of caffeine remain at the peak for about an hour. After this, the caffeine in your body starts to flush out and the effects become less noticeable.

According to this article, caffeine has a half-life of around 5-6 hours.

If you have low caffeine metabolism, the caffeine can last longer in your body. That means 5 Hour Energy Drink will stay longer in your body.

Alternatives To 5 Hour Energy Drink

If you’re in the mood for something else, or you’re only starting your energy drink journey then here’s a good list to try:


Overall, 5 Hour Energy Drink is great if you want a strong hit of caffeine. It definitely does its job of giving a big boost in a short time, but its high caffeine content and average taste knock some points off.

5 Hour Energy Drinks are the kind of drinks for when you’re on a mission to get something done. It’s definitely not something you’ll enjoy casually, but you can’t go wrong if you need energy quickly.

While 5 Hour Energy Drinks are efficient, their bitter taste will definitely not be well-received by many. Plus, if you’re caffeine-sensitive, this is definitely not the caffeinated product you should be having.

On that note, 5 Hour Energy also doesn’t provide a lot of actual hydration, so you might want to look to other energy drinks with a much larger volume of liquid if you’re looking to quench your thirst.
