What is Reign Inferno?

According to the product listing on Amazon, Reign Inferno energy drink is a “thermogenic fuel, fitness and performance drink”. The zero-sugar energy drink comes in four flavors:

  • Reign Inferno Red Dragon
  • Reign Inferno Jalapeno Strawberry
  • Reign Inferno True Blu
  • Reign Inferno Watermelon Warlord

What flavor is Reign Inferno Red Dragon? The flavor profile is a fruit punch with a bit of dragon fruit mixed in.

Does Reign Inferno Work?

  • Journal of Ginseng Research — “ginseng exerted a weight loss effect and slight effects on gut microbiota in all participants. In addition, its antiobesity effects differed depending on the composition of gut microbiota prior to ginseng intake.”
  • The Journal of Physiology — “…muscle carnitine can be increased by dietary means in subjects without carnitine deficiencies and that this has a clear influence on muscle metabolism and performance.”
  • Nutrients — “The variety of applications for which l-citrulline has been utilized underscores the importance of l-citrulline in vascular health, protein metabolism, and lipid metabolism.”

Who Makes Inferno?

Reign Beverage Company is behind Reign Inferno. However, you may know the name Monster better than Reign Beverage, as Monster is the Reign parent company.

The Monster Beverage Company has a Better Business Bureau profile with an A rating. Even though the business has been around for more than three decades, it is not accredited by the BBB. Now, the company responsible for Monster is American Fruits and Flavors, which has no BBB page at all.

Reign Inferno Claims

Reign Inferno claims to add fire to your workout with a “thermogenic fuel that burns calories and accelerates metabolism.” The Amazon description also claims that “Reign Inferno also contains the same attributes as Reign Total Body Fuel.”

Overall, the drink claims it can:

  • Ignite workouts
  • Increase metabolic energy levels
  • Improve exercise performance

It appears this is a hyped-up version of the original Reign, but more on that later.


Reign Inferno Ingredients

The Reign Inferno ingredient list is relatively short. The main components in the Proprietary Thermogenic Performance Blend are:

  • L-Citrulline
  • Panax Ginseng Extract
  • Natural Caffeine
  • L-Carnitine
  • Green Tea Extract
  • Capsicum

As listed on the label, other ingredients include l-leucine, l-isoleucine, l-valine, sucralose, coenzyme Q10, and various preservatives.

Does It Work?

Does Reign Inferno Work?

Let’s get to digging into the Reign Inferno ingredients. Because these ingredients are in a proprietary blend, we have no idea how much of each is included – aside from the caffeine, as Reign heavily advertises that their product contains 300mg of the stimulant.


L-citrulline is a non-essential amino acid converted to l-arginine and nitric oxide in the kidneys. There is no connection between l-citrulline and the main claims of increased metabolism and calorie burn.

Panax Ginseng Extract

Suppose you want to stretch things a bit and assume that rat research is comparable to human research. In that case, we can cite studies showing that Panax ginseng can help prevent obesity, like the one published in 2018 in the Journal of Ethnopharmacology. Unfortunately, there are no human studies that show the same benefit.


Reign Inferno contains 300mg of caffeine – the number one stimulant in the world. So, what will 300mg of caffeine do for your metabolism, and how many calories you burn?

“Overall, the current meta-analysis demonstrated that caffeine intake might promote weight, BMI, and body fat reduction,” according to Critical Reviews in Food Science and Nutrition.

What’s even better is that earlier research, this time published in the Iranian Journal of Pharmaceutical Research, shared that caffeine intake may also help prevent the regaining of weight after weight loss.


We know that Reign Inferno is all about fitness, right? It’s beneficial for them to include ingredients that directly affect how the body recovers from exercise. That’s where l-carnitine comes in.

According to research published in Nutrients, l-carnitine supplementation “alleviates muscle injury and reduces markers of cellular damage and free radical formation accompanied by attenuation of muscle soreness.” It helps your muscles recover and ease soreness.

Green Tea Extract

Green tea extract is one of our favorite weight-loss ingredients. It contains EGCG, which can increase metabolism independently of the caffeine in tea. However, we have no idea how much green tea is included, so we can’t show an effective addition.

Reign Vs Reign Inferno

What’s the Difference Between Reign and Reign Inferno?

The difference between Reign and Reign Inferno is nothing more than the ingredients in the proprietary blend mentioned above.

The caffeine content is the same across both, so you’re looking at the addition of l-citrulline, Panax ginseng, green tea extract, and l-carnitine.

Side Effects

Possible Reign Inferno Side Effects

The caffeine is the main contender for ingredients that cause side effects in Reign Inferno energy drink. With 300mg of the stimulant, you can expect that someone who’s not accustomed to that much will notice a difference in less than 15 minutes.

Uncomfortable side effects of caffeine can include:

  • Shakes
  • Jitters
  • Nausea
  • Headaches
  • Irritability
  • Difficulty Sleeping

How to Use Reign Inferno

Reign Inferno comes ready-to-drink in a single-serving can. You drink an entire can. Now, when you are supposed to use the product or how many you should drink daily, that’s not revealed on the official website description or Amazon.

Based on the caffeine content, we suggest drinking only one daily and never within five or six hours of bedtime.

Pros and Cons

Pros and Cons

We’ve learned a lot about the Reign Inferno drink, but what are the takeaways – the pros and cons?


  • Reign Inferno contains enough caffeine to boost metabolism.
  • May help athletes burn calories.


  • 300mg of caffeine is too much for some people.

VPX Sports filed a trademark lawsuit against Monster Energy Ltd. in California federal court, alleging that Monster’s “Reign Inferno” infringes trade dress covering VPX’s “Bang” energy drinks.

What Users Are Saying

What Users Are Saying

“I get the same boost of energy that your standard energy drink provides, but unlike stuff like Red Bull or Rockstar, it’s not full of sugar and your energy levels don’t crash after an hour. I also wasn’t sure the thermogenic ingredients would do much until I started sweating 10 minutes after drinking one. It’s an awesome choice for a pre-workout drink, but make sure not to drink it too early.”

“It’s not anything I would normally choose to drink prior to a workout or as fuel and sadly I have so many left to get through.”

“I enjoy this energy drink and if you are new to them or are sensitive to certain ingredients in Reign Thermogenic, you will feel a slight burning or warmth in your stomach.”
