Reign Inferno Watermelon Warlord Flavor Review

Reign Inferno Watermelon Warlord Flavor Review

We all know about Reign Energy. It contains nutrients, caffeine and is sugar-free, making it a great go-to drink for just about any physical activity.

Their new formula, Inferno, brings a lot of new elements to the classic mix. And now, it also comes in a new flavor: Watermelon Warlord.

But does new mean better? Let’s take a look and see if Reign Inferno Watermelon Warlord can rise up to the challenge.

Reign Inferno has all the ingredients regular Reign has but Green Tea Extract, L-Carnitine, and Panax Ginseng Extract are added for an increased thermogenic effect on users. Thermogenesis speeds up your metabolic rate during workouts and allows you to burn more fat.

Are you ready? Let’s go!

The Difference Between Reign and Reign Inferno

Since Reign products are advertised as performance and fitness drinks, they don’t stray from one another that much.

However, Reign Inferno amped their game a little better by adding Green Tea Extract, L-Carnitine, L-Tartrate, Panax Ginseng Extract, and Capsicum Oleoresin. Some of these ingredients are responsible for the Thermogenic effects on its users.

Thermogenesis is the significant increase in our metabolic rate, allowing us to burn food faster and absorb more nutrients.

Moreover, the Inferno line’s flavors also bring new and exciting combinations.

What can you get out of every Reign Inferno?

Caffeine Content

Just like the classic Reign formula, Reign Inferno Watermelon Warlord packs a whopping 300mg of caffeine in every can.

This is very near the 400mg ceiling that the FDA has recommended for our daily caffeine intake. Consuming such a high dosage of caffeine can be dangerous to many individuals, especially those who have just started drinking caffeinated beverages and those who are caffeine sensitive.

High caffeine doses can also cause restlessness, headaches, dizziness, and irregular heartbeats, among other symptoms. Journal studies also show that high levels of caffeine can trigger anxiety and panic attacks in certain individuals.

Moreover, regularly consuming a high amount of such elements can cause caffeine dependency and, worse, addiction.

Since Reign’s caffeine content is a bit high, it’s best to drink small amounts and know your body’s limits on caffeine.

Sugar Content

Reign Inferno products, like their classic counterparts, are sugar-free.

However, it does contain an artificial sweetener called Sucralose, dubbed one of the safest sugar substitutes in the market.

Research also indicates that it does not contain calories, unlike table sugars. The FDA also recommends it for the consumption of diabetics.

All these qualities ensure that Sucralose won’t give you a sugar crash like table sugar can.

Does Reign Inferno Actually Burn Calories?

Is Watermelon Warlord all bark and no bite?

Since it contains thermogenic ingredients, yes, Watermelon Warlord can burn calories!

This study proves that its green tea and capsicum content aids in fat loss by accelerating your metabolism.

Not only that, but the high dose of caffeine allows you to move quicker and longer than you can do regularly. And since this product does not contain sugar, you don’t have to worry about additional carbs that you have to lay off during your workouts.

Can Reign Inferno Watermelon Make You Crash?

This product is sugar-free, which means it cannot make you crash.

Only substances that contain table sugars can make you crash after a few hours of their consumption. You’ll know it’s a decline when you are experiencing fatigue, hunger, irritability, etc.

As previously mentioned, Reign formulas are advertised as a fitness and performance drink. It should make sense why there is no sugar in every can of both the original Reign and any from the Inferno line.

On another note, you can watch this Youtube video to know when to spot a sugar decline and how to counter it easily.

What Does Reign Inferno Watermelon Warlord Taste Like?

The natural Watermelon flavor brings a refreshing take on the Reign formula, and it really does taste like a fresh fruit juice.

However, the exciting part was probably feeling a little tingle on the tip of your tongue as there is quite a spicy aftertaste to it.

The sweetness of the drink is also reminiscent of candy. Dare I say that it can beat Sour Patch kids’ flavors of other brands in the market. Moreover, the carbonation of the product enhances its flavor even more.

When it comes to performative drinks, Bang is probably Reign’s other half. In addition to that, this brand also has a Wyldin’ Watermelon flavor! So if you like watermelon, Bang’s got you covered.

Like Reign, Bang contains 300mg of caffeine and is sugar-free.


If you don’t know Monster, then I am going to assume that you were born yesterday.

Monster has a zero sugar and zero-calorie energy drink in watermelon flavor too. It’s called Monster Ultra Watermelon. Unlike Reign Inferno, this beverage only has 150mg of caffeine.

On the other hand, its original flavor does contain a whopping 179mg of caffeine and 52g of sugar, which may cause a huge decline after an hour so.

So if you’re looking for a tasty beverage with a moderately high caffeine content, then maybe this drink is for you!

Now, let me tell you how unforgettable REIZE is.

If you’re fond of fun and fizzy flavors like Watermelon Warlord, then REIZE is right up your alley with its light carbonation and sweet taste.

But unlike Reign’s high caffeine content, REIZE only has 50mg, which means the risk for caffeine’s side effects is significantly lower with REIZE. Rest assured that you’ll get the energy boost you need, though.

In addition, the drink is also sugar-free and contains only 11 calories. It’s also very travel-friendly since you can just put it somewhere small, and it does not take up too much space in your bag or on your countertop.

It’s packed with Taurine, Ginseng, and B-Vitamins. You can get all these for just around $1, with the convenience of having them shipped right to your doorstep. So if I were you, I’d give REIZE a try today!

Other Notable Mentions

Still undecided? You can try making your own homemade energy drinks or check out these brands:


All in all, Reign Inferno Watermelon Warlord is an interesting addition to the brand’s already strong lineup.

The flavor is very appealing and sweet, and it’s also packed with a few new ingredients that come with the Inferno formula. These additions boost your metabolism, so your workouts will definitely pack more punch.

However, Reign’s caffeine content may be too high for caffeine-sensitive people. Always keep your consumption within the recommended daily limit, especially when consuming Reign.

If 300mg is too high for you, you may want to consider similar brands with less caffeine.

In my opinion, this drink suits those with active lifestyles the most, as its high caffeine content will allow you to stay awake and burn more calories.

If this is you, then, by all means, enjoy this fun fruity flavor of Reign!
