Sugar Content in 5-Hour Energy

5-Hour Energy shots are sugar-free. That’s why you don’t need to bother about experiencing a sugar crash at all.

The American Heart Association (AHA) proposes to keep our daily sugar intake:

  • below 36g (equivalent to 9 teaspoons) for men
  • below 25g (equivalent to 6 teaspoons) for women

Sugar can be harmful to you if overconsumed. Too much sugar can cause these complications:

  • weight gain
  • fatty liver disease
  • chronic inflammation
  • increased blood pressure
  • two types of diabetes

If you’re at risk for high blood sugar, you should regulate your sugar intake to avoid any side effects. 5-Hour Energy shots can be a good choice for a quick energy boost.


Sucralose is used to substitute the sugar in 5-Hour Energy shots. Interestingly enough, it starts off as refined sugar and then undergoes a multi-step chemical process.

According to this study, sucralose is 400-700 times sweeter than table sugar. That explains how sucralose can be a perfect sugar substitute. It doesn’t mess with your insulin levels or blood sugar levels.

The FDA approved sucralose safe for general use in 1999.

Calories in 5-Hour Energy

As 5-Hour Energy does not contain any fat, sugar, protein, or fiber, it has only 4 calories.

Compared to its mere 4 calories, a casual energy drink like Red Bull has 110 calories (per 8.4 fl. oz.).

The NHS states that recommended daily intake for an average woman is 2,000 calories and 2,500 for an average man. It will also depend on your height, age, lifestyle, and other factors.

5-Hour Energy is diet-friendly. It can also give you sufficient energy to hit the gym and lose weight!

How Well Does the Caffeine in 5-Hour Energy Work?

5-Hour Energy has 200 mg caffeine per shot

5-Hour Energy has around 200mg of caffeine in each serving of 1.93fl. oz. It’s highly effective and can help you to stay awake at night and do better in sports.

Other benefits of caffeine include:

  • increased alertness
  • improved brain function
  • boost long-term memory
  • reduces the risk of kidney stones
  • weight loss

However, consuming too much caffeine can be harmful to your health.

The FDA recommends that we keep our caffeine intake below 400mg which is equivalent to four to five cups of coffee.

Otherwise, over-consumption of caffeine can lead to these problems:

  • restlessness
  • insomnia
  • addiction
  • rapid heart rate
  • digestive issues
  • fatigue
  • muscle breakdown
  • higher blood pressure

Drinking 5-Hour Energy shots in moderation is essential to avoid these symptoms.

What Does Taurine in 5-Hour Energy Do?

Taurine is an amino acid that occurs naturally within our bodies. 5-Hour Energy shots contain around 479.9mg of taurine.

It also plays a crucial role in body functions like:

  • balancing electrolytes in the body
  • regulating calcium levels in certain cells
  • creating bile salts
  • supporting the development of the nervous system

Moreover, taurine deficiency can also lead to some problems. They are:

  • kidney dysfunction
  • developmental disorders
  • damage to eye tissues

Consuming an energy drink that contains taurine might help you if you have these problems.

How Do the Vitamins in 5-Hour Energy Actually Help?

B vitamins help to turn our food into energy, so they’re very important. 5-Hour Energy shots contain vitamins B3, B6, and B12.

Vitamin Bs make sure that the body’s cells are working properly. They also help to:

  • create new cells
  • convert food into energy (metabolism)
  • maintain healthy brain cells, skin cells

Vitamin Bs don’t have instant effects so you need to follow a well-balanced diet regularly to feel it.

Here’s a table containing the quantity of vitamins with their daily value percentage in a 5-Hour Energy drink:

VitaminAmount in 1.93 fl. oz.DV% (Daily value percentage)
Niacin (Vitamin B3)30 mg150% DV
Vitamin B640 mg2000% DV
Vitamin B12500 mcg8333% DV
Vitamin Bs in 5-Hour Energy

The amounts of vitamins B6 and B12 can be concerning at a glance, but there’s only little harm if you consume the drink occasionally. On top of that, B vitamins are water-soluble, so our bodies cannot hold them for much longer anyway.

A well-balanced diet contains enough B vitamins. Consuming more won’t further boost your energy levels.

Does 5-Hour Energy actually work?

How Long Does It Take 5-Hour Energy to Kick in?

It takes around 10-20 minutes for 5-Hour Energy to kick in, though results may vary

5-Hour Energy is served in tiny bottles of 1.93fl. oz. and is packed with 200mg of caffeine. So, the caffeine is delivered pretty quickly to the body. Most reviews claim it to be 10 to 20 minutes quicker compared to regular energy drinks.

Because of its bottle size, 5-Hour Energy can be your partner if you’re in a rush for an energy boost regularly.

Does 5-Hour Energy Actually Last 5 Hours?

The experience will vary from one person to the other, but it can definitely last 5 hours.

Depending on your caffeine sensitivity, 5-Hour Energy packs enough caffeine to keep you up for your all-nighters. Though some people report its effects to subside in 3-4 hours.

However, I think taking a few sips instead of drinking the whole bottle at once can give you a boost for a longer time.

How Long Does 5-Hour Energy Stay in Your System?

Depending on your caffeine metabolism and how used you are to energy drinks, 5-Hour Energy stays in your system for around 12 hours.

According to the American Academy of Sleep Medicine (AASM), caffeine has a half-life of 5 hours taking a total of 10 or more to get it out of your system.

Moreover, if you have a large body mass, it may take longer for the caffeine to circulate your body. 10 hours is just an estimate, and a lot of factors may contribute to how quickly your system eliminates them from your body.

How Many 5-Hour Energy Shots Can You Drink in a Day?

You should drink only one shot of 5-Hour Energy in a day.

5-Hour Energy has around 200 mg of caffeine. It is already a high amount, so drinking two of them in a day can leave you with a caffeine crash. Symptoms of caffeine crash include:

  • headache
  • inability to concentrate
  • irritability
  • extreme tiredness

That’s why you should only consume one shot of 5-Hour Energy when you really need a boost. It will make you feel recharged and give you enough energy to go on for a few hours.

Alternatives to 5-Hour Energy

If you want to go for a casual energy drink instead of 5-Hour Energy, you can try these:


Overall, I think 5-Hour Energy can help you do a lot with its quick energy boost.

Caffeine is one of its main ingredients which can improve your mood and brain functions. It also stimulates your brain and mood function to make you feel more awake.

However, not everyone is accustomed to consuming high amounts of caffeine in such a short time. If you have caffeine sensitivity, you shouldn’t consume 5-Hour Energy shots. This can leave you with a massive headache. 5-Hour Energy is more suitable for you if you drink around two to three cups of coffee every day.
