Reign Total Body Fuel Caffeine Content – Barista HQ

If you're looking for an energy boost, Reign Total Body Fuel is an excellent option. The caffeine content in a 16 fl oz can of these performance energy drinks is an astounding 300 milligrams!

However, excessive caffeine intake often leads to negative side effects, some of which I've been learning the hard way.

That's why knowing exactly how much caffeine you put into your body is essential.

Below I'll give you a better understanding of the caffeine content of Reign Total Body Fuel so you can safely enjoy the drink without any health concerns.

Each 16 fl oz can of Reign Total Body Fuel has 300 milligrams of invigorating natural caffeine when you choose from the Reign Core series or the Reign Inferno series.

Whether you get the Cherry Limeade, Watermelon Warlord, or my personal favorite, the Jalapeno Strawberry, all have the same caffeine content.

Reign has recently introduced its Storm line of drinks. They're sold in 12 Oz cans, each with 200 mg of caffeine. 

So, while it's still a lot of caffeine, you can opt for a little less with the Reign Storm energy drinks.

Reign Total Body Fuel Storm Different Flavors

Reign Energy Drinks Explained (Ingredients & Nutrition Breakdown)

Reign Total Body Fuel is an innovative and flavorful drink that supports peak athletic performance, offering athletes a better-for-you beverage choice.

Along with a heaping helping of caffeine, they also contain BCAAs, electrolytes, B vitamins, and CoQ10 so that you can make it through your workout (or your dinner with toddlers).

Reign now offers three lines of its energy drink: Core, Inferno, and Storm. Reign Inferno is a thermogenic beverage meant to help burn calories.

Like the Reign Core line, Inferno features 300mg of caffeine, coQ10, BCAAs, B vitamins, and electrolytes.

Reign Inferno does have a few new ingredients the Core line doesn't.

It has the pre-workout ingredients citrulline and ginseng, which are listed higher on the product than the caffeine content.

Inferno also has common weight-loss ingredients like carnitine l-tartrate, green tea extract, and capsicum oleoresin.

Reign Storm is a clean energy drink for a broader audience, including health-conscious dads like me.

You can tell just by looking at the branding of the beverage that this one is different from its predecessors.

Reign Storm is an energizing, fat-burning, and immune-supporting energy drink with an immunity blend containing Zinc and Vitamins A, B, and C.

Storm is sold in a slim, sleek 12oz can with 100mg less caffeine than Core and Inferno.

They’re also available in so many flavors, so you’re sure to find one that you like. You won't have to settle for a chalky taste like some other energy drinks have.

If you're unsure where to start, let me recommend Jalapeno Strawberry.


Caffeine = Good Ingredient

Natural caffeine, the star of the show, is a stimulant that helps increase alertness, improve focus, and reduce fatigue. Caffeine is safe, but be mindful of your daily intake.

BCAAs = Good Ingredient

Branched-Chain Amino Acids like L-leucine, L-isoleucine, and L-valine are essential amino acids and the building blocks of protein.

They are vital in supporting muscle recovery and reducing muscle fatigue during physical activity.

They’re “essential” because your body doesn’t make them on its own you have to get them from food and drinks like Reign Total Body Fuel.

Citric Acid = Neutral Ingredient

In an energy drink, citric acid is used as a flavoring agent and helps enhance the drink's tartness and acidity.

It’s generally recognized as safe, but it doesn’t add much to the effectiveness of the drink.

Natural Flavors = Neutral Ingredient

Flavors from natural sources like fruits, herbs, or spices enhance the taste and aroma of the energy drink. While they make it more palatable, they don’t improve the effectiveness of the drink.

Moreover, the common assumption is that "natural" flavors are healthier.

However, advancements in the science of flavoring have led to many artificial flavors possessing identical chemical structures to their naturally occurring counterparts.

Carbonated Water = Good Ingredient

Carbonated water gives the energy drink a bubbly and invigorating sensation.

While it may seem like there’s no real reason for it to be there, caffeine enters through the stomach, and carbonation makes it even easier for it to get in.

Electrolytes (Sodium Citrate and Potassium Citrate) = Good Ingredient

Electrolytes like sodium and potassium citrate help maintain proper fluid balance, support hydration, and aid muscle function.

Many energy drinks do not have electrolytes, so the inclusion of them in Reign makes this great for fitness enthusiasts.

Coenzyme Q-10 = Good Ingredient

Coenzyme Q-10 is a vitamin-like substance found throughout the body. It’s a natural antioxidant that aids in cellular energy by contributing to the production of adenosine triphosphate (ATP).

It’s also required for the proper function of many organs and biochemical reactions.

Sucralose = Neutral Ingredient

Sucralose is a zero-calorie artificial sweetener to sweeten the energy drink without adding significant calories.

It’s safe to consume and has been approved by the FDA as one of the eight permitted low- and no-calorie sweeteners for use in the U.S. food supply.

So, while I listed it as a neutral ingredient because research is mixed, it may be a better alternative to sugar.[1]

Magnesium Citrate = Good Ingredient

Magnesium citrate can promote healthy digestion, regulate the nervous system, encourage natural sleep (excellent when drinking this much caffeine), improve bone health, and protect heart health.

B-Vitamins = Good Ingredient

B-Vitamins, including B3 (niacin) and other B-complex vitamins like B6 and B12, play essential roles in energy metabolism.

They help convert food into energy and support overall cellular function.

These ingredients work together to boost your energy, support physical performance, and enhance the flavor.

This unique formula allows me to enjoy Reign Total Body Fuel while chasing a PR in the gym (as a pre-workout) or trying to stay awake after lunch.

Reign Total Body Fuel only has 10 calories per can, so if you’re counting your calories like me to regain your high school physique, Reign won’t throw you off track.

Calories give your body energy, but consuming too many can result in weight gain and, ultimately, obesity.


The first question people ask about energy drinks is how much sugar they have.

Fortunately, Reign Total Body Fuel is sugar-free and has zero artificial flavors, even though it has more caffeine than most drinks.

It has zero sugar and instead uses sucralose and acesulfame potassium sweeteners.

The health risks of sucrose and acesulfame potassium are debatable, but the FDA believes they are safe for everyday use.[2]

However, added sugar has been proven to lead to weight gain, diabetes, and heart disease.[3]


Reign Total Body Fuel has 3g of carbs. For most people, that's considered relatively low.

Carbohydrates are a primary energy source for the body, and they can provide a quick boost of energy.

If you need more carbs for sustained energy, you can have an energy drink with more carbs or snack on foods high in carbs.

Benefits & Risks Of Drinking Reign Total Body Fuel

Reign Total Body Fuel offers a range of benefits for athletes and tired dads like me. The best thing it does is enhance energy and focus with caffeine, B vitamins, and amino acids.

Offering zero sugar, high fructose corn syrup, and zero artificial flavors or colors, it's about as healthy as an energy drink can be.

When you choose a clean energy drink like Reign Total Body Fuel, you'll enjoy a sustained boost of vitality and long-lasting energy that will carry you all day long.

However, Reign Total Body Fuel has 300mg of caffeine, and that caffeine amount isn't for everyone.

High levels of caffeine can lead to adverse side effects even in healthy adults with an active lifestyle.[4]

Excess caffeine can lead to adverse effects, like:

  • High blood pressure
  • Difficulty in breathing
  • Diarrhea
  • Anxiety
  • Jitteryness
  • Difficulty sleeping
  • Kidney Stones
  • Liver problems
  • Fatigue
  • Digestive issues
  • Headache
  • Rapid heart rate
  • Insomnia
  • Dehydration
  • Death (In extreme cases)

Who Should Drink Reign Total Body Fuel?

Reign Total Body Fuel is one of the most caffeinated beverages on the market, making it perfect for bodybuilders, weightlifters, CrossFitters, and anyone who enjoys exercise (even if your exercise is chasing your kids around the park).

All Reign lines, but Storm especially, are great if you want a clean energy drink that will help you power through your day without any unnecessary ingredients.

Their caffeine is sourced from green coffee beans instead of synthetic sources, giving you a burst of clean energy that won't have you crashing later on.

Don’t get me wrong, this isn’t a “green drink” by any means, but as far as energy drinks go, this is one of the purest you’ll find.

Who Should Avoid Reign Total Body Fuel?

Reign Total Body Fuel is considered to be generally safe for healthy adults.

However, if you are sensitive to caffeine, have certain medical conditions, or take medication that may be affected by caffeine, you should not drink Reign.

Additionally, pregnant women, women who are nursing, and children should not consume Reign Total Body Fuel.

If you've never had a drink with this much caffeine, you should ease into it. 300 mg of caffeine is a lot, and you'll need a high tolerance.

Drink small serving sizes to assess your body's response before adding it to your routine.

Reign Caffeine Content Vs. Other Energy Drinks

Reign Vs Bang Energy Drinks

Every 16 fl oz can of Bang contains 300 milligrams of caffeine. That's the exact same amount as Reign Total Body Fuel. These energy drinks are very similar to one another.

Reign tends to be cheaper, but Bang has more flavors and nutritional value. If the fancy ingredients of Bang (like its Super Creatine) are less important to you, Reign is a good alternative.

Personally, all I'm looking for is a healthy kick in the butt to keep me going, so I like Reign Storm.

Reign Vs RedBull

RedBull is the granddaddy energy drink, and the 80mg of caffeine in a 250-ml can (about half the size of Reign) is considerably less than the 300mg in a 16 oz can of Reign.

So if you don't need the extreme caffeine amount, skip Reign Total Body Fuel and get a RedBull.

However, a can of Red Bull Energy Drink contains 27g of sugar, so be mindful of that if you opt for a RedBull.

Reign has become as accessible as RedBull and is available in most of the same locations, so finding one shouldn't be an issue.

Reign Vs Monster Energy

Monster beverages have 160 mg of caffeine in each 16 fl oz can. That's twice as much as Redbull but about half as much as Reign Total Body Fuel and Bang.

This popular drink is the "Mama Bear" of these three drinks as far as caffeine content goes.

Regarding sugar content, a 16oz can of Monster Energy has a whopping 54g of sugar. It also has 230 calories to Reigns 0. Based on that alone, I'd choose Reign every time.

Reign Vs Coffee and Tea

When you drink an 8-ounce cup of brewed coffee, you usually consume about 100 milligrams of caffeine. An 8-ounce cup of black tea contains approximately 50 milligrams of caffeine.

Both are considerably less than the 300 milligrams in a 16 oz can of Reign.

How To Drink Reign Energy Drink Safely (Moderation Is Key)

The best way to drink and enjoy Reign and all other caffeinated beverages is in moderation.

Moderation is key because each 16 fl oz can have 300mg of caffeine, and that much caffeine in excess can be bad news. 

It can lead to overstimulation, sleep disruption, dehydration, and the risk of caffeine dependency and tolerance.

The FDA recommends that adults only drink 400 mg per day.[5] Consuming one can of Reign would almost top off your daily allowance.

Consuming caffeine in moderation helps avoid negative effects and promotes overall well-being.

However, caffeine will affect everyone differently, and what works well for me may not work well for another. You need to experiment and see what works for you.
