How Much Caffeine Does Reign Have?

Reign Energy has 300mg caffeine content (sourced from green coffee beans and tea leaves) in every 16 fl.oz can, which is a significantly high amount for an energy drink.

A key part of any energy drink, some of the benefits of caffeine includes:

  • Improved cognition
  • Reduced inflammation
  • Lowered the risk of chronic diseases

If we look at the FDA guidelines, Reign’s 300mg of caffeine per serving is quite close to the recommended daily intake which is no more than 400mg.

Of course, depending on your caffeine tolerance, your mileage may vary on how much caffeine you can actually handle. However, you should still be careful not to consume an excessive amount in case of possible side effects.

While it’s clear that caffeine can give you a boost, too much of it is definitely not a good thing. Having too much caffeine in a short period can lead to notable negative symptoms such as:

  • Restlessness
  • Jiterriness
  • Heart Palpitations
  • Insomnia
  • Anxiety

In general, while having some amount of caffeine in your diet may be beneficial, be sure to know your own tolerances before diving off the caffeinated deep-end with Reign, especially if you happen to be caffeine sensitive.

Does Reign use synthetic caffeine?

Reign is a non-carbonated sports beverage with no calories, artificial flavors, colors, and preservatives. Contrary to this, the product contains electrolytes, vitamins, and minerals, in addition to 300mg of caffeine, equivalent to about three cups of coffee.

It is important to remember that while Reign has some health benefits, it also comes with some significant downsides. For instance, this product contains a lot of caffeine and sugar, which can cause jitters, headaches, and weight gain. Since it is also high in calories, keep in mind that this is not the ideal drink if you are trying to lose weight.

Reign Energy Drink Calorie Content

The calorie content of Reign is usually somewhere between 0 to 10 calories per 16 fl.oz, depending on which flavor you happen to find.

As a low-calorie energy drink, Reign is definitely a lot healthier for you than most of the sugar-filled fare you often find off store shelves, and is definitely a lot better for your diet plan as well, if you do happen to follow one.

It is also important to follow the recommended calorie intake daily to avoid health complications. For reference, the recommended daily calorie intake is 2,000 to 2,400 calories for women and 2,400 to 3,000 calories for men.

So while a can of Reign may give you a good boost, it’s not exactly going to help fuel the entirety of your workout sessions, so be sure to have a proper meal in addition to Reign to give yourself some proper energy to work with.

Reign Energy Drink Sugar Content

Reign Energy is entirely sugar-free, which makes it a fairly healthy energy drink option if you’re concerned about your overall sugar intake.

With Reign being sugar-free, you don’t have to worry about a “sugar crash” which you’ll often get in sugary drinks, which is definitely a plus.

As always, too much of anything isn’t good for you. So it’s important to follow the AHA’s daily sugar intake recommendation which is not more than 25g for women and 36g for men.

Some of the symptoms that you may experience after consuming too much sugar includes:

  • Insomnia
  • Weight gain
  • Low energy
  • Constant craving
  • Unexplained bloating

But considering Reign doesn’t have any sugar, you’re pretty unlikely to suffer from any sugar-related side-effects from this energy drink, although that doesn’t really give you the liberty to drink more than one can due to the caffeine present.

Does Reign Energy Drink Have Artificial Sweeteners?

Sucralose and Acesulfame Potassium are the artificial sweeteners found in Reign Energy Drink.

As zero-calorie sweeteners, they do not affect the nutritional value of Reign and thus won’t have a direct impact on your diet.


Sucralose is 600 to 700 times sweeter than sugar and it does not have a bitter after taste like other sweeteners.

The good news is, it has little to no effect on your blood sugar and insulin level (at least, allegedly) which makes it a safe ingredient in energy drinks. Hence, energy drinks with Sucralose are suitable for people with diabetes.

Have a quick look at this video for quick explanation about Sucralose:
What is Sucralose?

Acesulfame Potassium

Acesulfame Potassium is also known as Acesulfame K or Ace-K. It’s an artificial sweetener that’s nearly 200 times stronger than sugar, although it has a slightly bitter after taste, which is it is often blended with Sucralose or Aspartame.

Although it won’t have an impact on your calorie intake, you do need to be aware of the risks associated with it, as long-term use of artificial sweeteners is still a sketchy subject.

In any case, the FDA approved the use of artificial sweeteners such as Sucralose and Ace-K in drinks and foods. So, as long as you don’t consume too much, you’re safe.

Other Ingredients


There is 1000 mg of BCAAs in a can of Reign Energy drink, which includes L-Valine, L-Isoleucine, and L-Leucine.

Branch Chained Amino Acids (BCAAs) are mostly known as supplements taken to boost muscle growth and improve exercise performance, while also assisting in increasing muscle mass.

L-Valine is chemically known as proteinogenic amino acids which is an essential amino acid that plays a key role in stress management, muscle support, immune system support, and healthy growth.

L-Isoleucine boosts energy and speeds up healing injured arms. It can also help muscle development and lean body mass. It also plays a key role in forming protein breaking down food and providing energy.

L-Leucine plays an important role in the synthesis of protein and metabolic functions. It helps to regulate blood sugar levels, repair or growth of bone and muscle tissue, production of growth hormones, and heal wounds.

While important in maintaining a healthy diet, BCAAs cannot be produced naturally. Instead, it has to be supplemented through a healthy diet.

Among the benefits of BCAAs include:

  • Improved liver health
  • Increased muscle growth
  • Decreased muscle soreness
  • Prevent muscle deterioration
  • Reduce exercise fatigue

That being said, while the BCAAs content in Reign is a great addition, it’s definitely not the sole reason you should be having Reign, especially since you most likely already have a sufficient intake of BCCAs from your daily diet.


Consisting of Vitamins B3, B6, and B12, B-Vitamins are present in Reign and play a key role in your overall bodily functions, albeit their overall content in Reign isn’t quite something to write home about.

Similar to the BCAAs content, while the B-Vitamin content in Reign is definitely a welcome addition, you’re probably going to get more bang for your buck from actual B-Vitamin supplements if you’re in need of them.

In any case, I’ve listed the B-Vitamins found in Reign down below, and for more information of B-Vitamins, check out this handy resource portal here.

PurposeAmount per 16 fl.oz of ReignTolerable Upper Intake Level
Vitamin B3 (Niacin)Helps body release energy; keeps skin healthy.21.6mg35mg
Vitamin B6Store energy from protein and carbohydrates; formation of red blood cells2.0mg100mg
Vitamin B12Release energy from food; forms red blood cells; keeps the nervous system healthy6.25µg

Coenzyme Q10

Coenzyme Q10 is a fat-soluble, vitamin-like substance that helps convert food into energy. The production of Coenzyme Q10 decreases as people age. So, having such an ingredient in your Reign Energy drink presents possible health benefits.


Electrolytes are present in the Reign Energy drink in the form of calcium, potassium, and sodium, which are essential to your body needs in order to regulate muscle contraction and keep you hydrated.

Is Reign Total Body Fuel Bad For You?

So long as you’re having it in moderation and only when you need to, Reign pretty much functions how an energy drink should – boosting your energy and increasing your performance.

However, you do need to take note of the relatively high content of caffeine, especially if you are caffeine-sensitive.

The electrolytes present in the Reign Energy Drink can help to replenish the salt content in your body that is lost during a workout. Nevertheless, this is only helpful if you are doing strenuous exercise.

How unhealthy is Reign energy drink?

Reign energy drink is unhealthy due to its high sugar and caffeine content. It provides the needed adrenaline rush, but, like other energy drinks, it can cause dehydration and irritability if consumed in excess.

Not only that, but it is devoid of nutritional value. As a result, it is best avoided by children, minors, immunocompromised people, and pregnant women.

Can I Drink Reign Every Day?

Considering that Reign’s 300mg caffeine content is still within the recommended daily limit of 400mg caffeine level, you can definitely have a can of Reign every day.

That being said, you probably shouldn’t go over more than one can a day, as the high caffeine content can lead to some notable side-effects.

Furthermore, having such a strong energy drink daily will make you eventually build up a tolerance to it, which means you might have to gradually increase on your caffeine intake each time in order to gain the same prior benefits.

My personal take on this is to drink in moderation to avoid caffeine addiction. So, it is best to alternate your consumption with other non-caffeinated beverages.

Reign vs Bang

Final Thoughts

If you’re looking for a low-calorie energy drink with stronger caffeine, Reign Energy is definitely a strong choice.

It is designed for people who live an active lifestyle and in need of a quick booster to level up their exercise performance. And if you belong to such a category, Reign Energy might be worth a try.

That being said it contains 300mg of natural caffeine, which is quite close to the recommended intake per day, and isn’t quite as friendly as other energy drinks if you happen to be caffeine-sensitive.

As such, I recommend you stick on only a can of Reign Energy per day, whilst steering clear from other caffeinated beverages as to avoid giving yourself any caffein-induced side-effects.

All-in-all, Reign Energy drink is formulated to help you stay alert and energetic the entire workout session, so as long as you consume it responsibly and are well aware of the high caffeine content.
