A shot of 5 Hour Energy
5-Hour Energy is served in shots of 1.93 fl. oz.

The 5-Hour Energy drink has a good reputation when it comes to giving a quick boost for mentally demanding tasks and meeting deadlines around the corner.

The best thing about 5-Hour Energy is that it’s served in 1.93 fl. oz. shots. These shots contain caffeine, sucralose, taurine, glucuronic acid, B-vitamins, and other ingredients.

I get quite amazed at how such a small shot of 5-Hour Energy can contain these many ingredients!

Do you ever wonder what these ingredients actually do?

5-Hour Energy Caffeine Content

5-Hour Energy has 200 mg of caffeine in a shot of 1.93 fl. oz.

It has quite a lot of caffeine, especially considering its small serving size.

For comparison, a 16 fl. oz. can of Bang energy drink has 300mg of caffeine, which is roughly 18.75mg of caffeine per fl. oz. Meanwhile, 5-Hour Energy has 200mg of caffeine in a 1.93fl. oz. shot — just a little shy of 2fl. oz. — which is pretty intense.

I prefer to keep my daily caffeine intake at around 200mg. This gives me the boost I need without experiencing a caffeine crash afterward. A shot containing 200mg of caffeine is perfect for me. So, it works pretty well when I need an energy boost around mid-day.

However, you should bear in mind that 200mg of caffeine in a shot is a lot. Your body needs to absorb it in a shorter period compared to regular-sized energy drinks. This may be something your body isn’t used to.

For reference, 400mg is the daily limit of caffeine intake by the FDA. If you consume any more than that you may experience some side effects including:

  • irregular heartbeat
  • nausea
  • digestive Issues
  • sleeplessness
  • anxiety
  • caffeine tction

These are things you won’t have to worry about if you drink 5-Hour Energy shots in moderation.

Sugar Content In 5-Hour Energy

5-Hour Energy shot doesn’t contain any sugar. Instead, an artificial sweetener called sucralose is used as a substitute. Bearing that in mind, you don’t have to worry about any sugar crash at all.

The AHA recommends keeping our sugar intake below 36g for men and 25g for women. Or else, you might face complications from consuming too much sugar. These complications include:

  • inflammation
  • higher blood pressure
  • type-2 diabetes
  • weight gain
  • fatty liver disease


5-Hour Energy drink uses sucralose as a substitute for sugar. It is a no-calorie sweetener, popularly known under the brand name Splenda. Sucralose is 600 times sweeter than sugar too.

It’s been approved by the FDA for general use in 1999.

However, its long-term effects are still unknown. I still think it’s best to limit sucralose intake, to be on the safe side.

Other Ingredients In 5-Hour Energy

Aside from the ingredients discussed above, 5-Hour Energy also has B-vitamins, taurine, N-Acetyl L-Tyrosine, and glucuronic acid.

Keep reading to find out more about these ingredients.


Each shot of 5-Hour Energy contains vitamins B3, B6, and B12.

B vitamins are essential for converting food into our energies. They also create new blood cells and maintain different types of cells. In addition, they are water-soluble and don’t get stored in our bodies. This is why we need to consume foods that are rich in B vitamins daily.

Here’s an easy-to-read table below with the amount of each B vitamin in 5-Hour Energy:

Name Of VitaminsFunctionsAmount present in 5-Hour Energy
(1.93 fl.oz)
Vitamin B3/Niacinacting as an antioxidant to help the body function, converting nutrients into energy, and repairing DNA30mg
Vitamin B6/Pyridoxinesupporting the central nervous system 40mg
Vitamin B12/Cobalaminmaintaining brain control by producing red blood cells500mcg
B vitamins in 5-Hour Energy


5-Hour Energy drinks contain around 479.9 g of taurine which s a common ingredient in energy drinks. It’s known to have many benefits.

Some of them are:

  • liver protection
  • added energy when exercising
  • regulate electrolytes and minerals
  • heart health improvement

According to this study, taurine has similar functions as caffeine in energy drinks. Caffeine and taurine both improve cognitive performance. Moreover, they reduce reaction times in the working memory tasks.

Interestingly enough, the two have opposing effects on our central nervous systems. Caffeine acts as a stimulant, while taurine acts as an agonist for GABA receptors.

N-Acetyl L-Tyrosine (NALT)

N-Acetyl L-Tyrosine, tyrosine for short, is a dietary supplement that improves alertness, attention, and focus.

It is known for producing important brain chemicals that help nerve cells to communicate and may even regulate mood. It is “generally recognized as safe” by the FDA but it may cause side effects when used with certain medications.

However, the amount of tyrosine in 5-Hour Energy drink is unknown. So, its effectiveness is not certain.

Glucuronic Acid

As per the label of the shot, 5-Hour Energy has glucuronic acid from glucuronolactone. This acid is found in various sources such as xanthan gum and Kombucha tea. It helps to regulate metabolism within the body.

Glucuronic acid is responsible for the detoxification of toxic substances inside our bodies.

It binds itself to substances like hormones, drugs, and toxins. Furthermore, it facilitates and transports these substances around the body.

Thus, we can say that this ingredient can be beneficial in an energy drink.

Calories In 5-Hour Energy

5-Hour Energy drink only has 4 calories. That’s a small amount compared to other energy drinks. For reference, a 16 fl. oz. can of Monster has 210 calories, and an 8.4 fl. oz. can of Red Bull has 110 calories.

The recommended daily calorie intake for an average adult is as follows:

  • 2000 calories for women
  • 2500 calories for men.

A mere 4 calories of 5-Hour Energy wouldn’t add much to your daily calorie intake. I suggest this booster with a meal.

What Is In 5-Hour Energy That Gives You A Boost?

5-Hour Energy drink has a special blend that can give you a quick boost. This energy shot has great ingredients to help enhance your focus and alertness.

Let’s have a look at the ingredients of the special blend:

  • Caffeine
  • Tyrosine
  • Phenylalanine
  • Taurine
  • Citicoline
  • Malic Acid
  • Glucuronolactone

Among these ingredients, people know caffeine for its ability to give an energy boost. Additionally, it’s a stimulant that increases your brain and nervous system activities.

Is 5-Hour Energy Approved By The FDA?

According to the FDA, dietary supplements don’t need to be approved. So, no. 5-Hour Energy drink shots are not approved by the FDA.

However, dietary supplements must comply with the provisions of the Dietary Supplement Health and Education Act. This is regulated by the FDA. The FDA also takes action for dietary misbranded supplements that reach the market.

Can 5-Hour Energy Make You Crash?

5-Hour Energy drink has a high amount of caffeine, drinking it irresponsibly can cause caffeine crash.

Symptoms of caffeine crash include:

  • extreme tiredness
  • inability to concentrate
  • irritability
  • headache

You should limit yourself to one shot of 5-Hour Energy in a day to avoid caffeine crash.

Alternatives To 5-Hour Energy

Here’s a list of other energy drinks that you can try:

Key Takeaways

5-Hour Energy shots give enough energy to beat the afternoon slump and work for long hours. The blend containing caffeine, taurine, glucuronic acid, and other ingredients make it possible.

Caffeine seems to be the most important ingredient in this energy shot. Its benefits improve mental alertness, boost long-term memory, and increase metabolism rate.

However, 5-Hour Energy has 200 mg of caffeine in a tiny bottle, so the caffeine is highly concentrated. Caffeine gets delivered to the bloodstream quicker than other regular-sized energy drinks.

5-Hour Energy shots may be more suited to you if you have two to three cups of coffee every day. Just remember to limit it to one shot per day!
