Reign energy drink’s nutrition facts include beneficial ingredients like BCAAs, B-vitamins, and Potassium. Each can also include 10 calories and 300 mg of caffeine while also being sugar-free. Electrolytes like sodium and potassium can also help you hydrate after your workouts.

But there’s a lot more than first meets the eye. For a more detailed answer, with an in-depth look at everything you want to know about the nutritional facts of Reign Energy Drink, stick around…

Reign Energy Drink Calorie Content

A 16 fl.oz can of Reign usually has somewhere between 0 – 10 calories, which is a significantly lower amount than many other sugary energy drinks.

For reference, a standard 8.4 fl.oz can of Red Bull has 80 calories, while a 16 fl.oz can of Monster has 210 calories.

Most of the immediate rush of energy from Reign is from its caffeine, which binds with the adenosine receptors in your brain, making you feel less tired and more alert than you actually are.

There aren’t many calories in Reign, which is great if you’re looking for a low-calorie drink that won’t affect your overall diet, but not so much if you actually need more fuel for your cells.

For your information, the daily recommended caloric intake for healthy adults is between 2000 to 2400 calories for women and 2400 to 3000 calories for men.

As such, Reign works best when you also consume some healthy calories to fuel your cells, so you don’t suddenly run out of actual energy halfway through your task.

Reign Energy Caffeine Content

Each 16 fl.oz can of Reign contains 300mg of caffeine that is naturally sourced from green coffee beans and tea leaves.

With 300mg of caffeine, Reign is one of the strongest energy drinks available, right alongside the likes of Bang and canned G Fuel.

As Reign is a workout drink, the extra caffeine may be beneficial to you before your daily workout, as caffeine has been noted to increase exercise performance.

Even so, 300mg is a lot of caffeine, so unless you have a pretty high caffeine metabolism, you probably shouldn’t be downing a full can of Reign in one go, especially if you happen to be caffeine-sensitive.

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

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

Therefore, be sure to keep your caffeine intake to a tolerable minimum, and try not to have any other beverages with caffeine such as coffee or tea, or you might find yourself over that caffeine limit pretty soon.

How Much Sugar Is In A Reign Energy Drink?

As Reign is sugar-free, you don’t have to worry about all that pesky sugar possibly ruining your health.

While this means you won’t get that good old dopamine hit you usually get from sugary energy drinks, it’s a decent trade-off in my view considering it’s also a lot healthier.

You also don’t have to worry about getting a sugar crash from Reign, as there’s not really anything in it that can raise your blood sugar levels by a significant amount.

Does Reign Energy Have Artificial Sweeteners?

While free of regular sugar, Reign Energy contains some artificial sweeteners, namely sucralose and acesulfame potassium.

As both sucralose and acesulfame potassium are zero-calorie sweeteners, you’ll be getting the sweetness without all the guilt that comes along with it, which is a plus.

That said, controversies about the long-term use of artificial sweeteners do exist, but the FDA has approved them for general use, so as long as you’re not consuming too many artificial sweeteners, you should be just fine.

However, if you’re not too keen on artificial sweeteners and would prefer some old-fashioned sugar, have a look at the article I’ve written on the best energy drinks with less sugar for some great options.

Other Ingredients In Reign Energy Drink


Reign contains 1000mg of BCAAs (Branch-Chained Amino Acids), which includes L-Leucine, L-Isoleucine, and L-Valine.

BCAAs provide you with a source of protein along with a whole host of possible benefits, namely:

  • Increasing muscle growth
  • Decreasing muscle soreness
  • Reduce exercise fatigue
  • Preventing muscle deterioration

Given that Reign generally advertises itself as a pre-workout drink, having BCAAs does seem like a pretty good addition to your exercise routine.

Saying that, however, you’re probably going to get the necessary amount of BCAAs from a moderately varied diet, so the benefits from Reign may not really be as pronounced as advertised.

So, while the BCAAs in Reign seems beneficial, a balanced diet means that the BCAA content in Reign is rendered a bit of a moot point.


B-Vitamins are present in most energy drinks, including Reign.

I’ve listed all the B-Vitamins found in Reign in the table below, but if you want more information on B-Vitamins, Harvard has a pretty handy resource here.

Is Reign Suitable For A Keto Diet?

As Reign is sugar-free and doesn’t have complex carbohydrates, it should be completely compatible with a standard keto diet

Keto Diet is a low-carb, high-fat diet that can provide health benefits such as weight loss and general health improvements.

If you’re on the Keto Diet, you will want to reduce your carbohydrate intake, and as Reign doesn’t seem to have any sugars or complex carbs, it should be perfectly compatible with the Keto diet.

For more information on how suitable Reign is for your diet, be it vegan or gluten-free, check out the article here, and for more information on the keto diet and energy drinks, read all about it in my comprehensive guide.

Reign Energy Drink Side Effects

As long as you’re relatively healthy, and keep your caffeine intake at a tolerable level, you shouldn’t experience any adverse side effects from Reign.

Like most caffeinated beverages, the main concern always lies in overdosing on caffeine, which can lead to some notable side effects, as stated above.

Given that Reign has 300mg of caffeine by default, it’s pretty easy to find yourself going over the daily recommended caffeine limit, especially if you’ve already had a caffeinated beverage beforehand.

While energy drinks such as Reign can give you a pretty good boost, be sure to know your caffeine tolerance, or you might find yourself a lot more jittery than usual.

Can you drink 2 reigns in a day?

I reckon it’s best to maximize consuming Reigns energy drink to just 1 can a day. This is because of the drink’s high caffeine dosage.

At 300mg of caffeine in a 16 oz can, one can should be the stopping point for most people. As per the FDA recommendation, a maximum of 400mg of caffeine daily should be kept in mind, otherwise side effects start to occur.

Reign VS Coffee

When it comes to a can of Reign or a cup of coffee, it really comes down to personal preference and what you’re actually looking for in your caffeinated drink.

Coffee is one of the most widely consumed caffeinated beverages on the planet, so Reign would really have to stand out in order to sway the hardened coffee drinkers out there.

For the most part, energy drink consumers and coffee enthusiasts rarely cross paths. Although both do similar things, there are few details as to why you might prefer one over the other.

It mostly comes down to what you enjoy from a caffeinated beverage; do you like the rich aromatic flavor of a coffee? Or do you prefer the carbonated, buzzy feel and wide variety of flavors of an energy drink?

Of course, there are other factors at play. For example, coffee has a higher antioxidant content, while on the other hand, for energy drinks, you’ll get to know everything that goes into the drink from its nutritional label and they generally include a bunch of ingredients that coffee lacks – like B vitamins.

Ultimately, the choice is up to you, and no matter what you decide, it’s a good idea to keep in mind that although caffeinated beverages may be great, you can definitely have too much of a good thing.

Reign Energy Alternatives

Reign may be great if you work out a lot and can handle so much caffeine all at once, but here are some other good options if you’re open to trying something different from Reign:

There are also some awesome powdered options such as:

I usually prefer energy drink powders over the ready-to-drink variety because they’re more convenient and versatile, but also usually a lot more affordable.

REIZE (10 out of 10)

REIZE is awesome.

While Reign may have some pretty interesting nutritional facts, I feel that REIZE is definitely a cut above.

REIZE is a powdered energy drink that comes in convenient 4g sachets. With a sensible 50mg of caffeine, REIZE is completely sugar-free, with only 11 calories per drink.

REIZE also contains a great blend of beneficial smart ingredients such as taurineginseng, and B-group vitamins, which come together to provide you with the perfect energy boost, without the sugar crash afterward.

Perhaps best of all, you can get REIZE shipped right to your door for only about $1 per drink, which is great value for money.

Try REIZE today and I’m sure you’ll soon agree that it’s a smarter option than Reign.
