What is Reign Energy Drink?

Reign Total Body Fuel is an energy drink produced by Monster Beverage Corporation. It was launched in 2019 as a zero sugar, low calorie beverage designed to meet the needs of athletes and fitness enthusiasts.

Reign is marketed as a “fitness-focused” energy drink that can help “fuel workouts and active lifestyles”. It contains branched-chain amino acids (BCAAs), electrolytes, antioxidants and caffeine to provide energy, hydration and muscle recovery.

Compared to traditional energy drinks, Reign has zero sugar and a more natural ingredient profile.

Why Drink Reign Energy Drink?

There are several potential benefits associated with drinking Reign energy drinks:

Provides Clean Energy

The 300mg of natural caffeine in Reign comes from green coffee beans and green tea leaves. This provides a clean energy source without excessive sugar.

Caffeine is a stimulant that can enhance alertness, focus and physical performance. The natural caffeine in Reign delivers an energy boost without crashing later.

Supports Exercise Performance

Reign contains branched-chain amino acids (BCAAs) – leucine, isoleucine and valine. BCAAs play a key role in muscle protein synthesis and reducing fatigue.

The BCAAs in Reign can help boost endurance, delay muscle fatigue and aid workout recovery. This makes it useful as a pre or post-workout drink.

Promotes Hydration

Reign is formulated with electrolytes including sodium, potassium, calcium and magnesium. Electrolytes are essential for maintaining fluid balance and preventing dehydration.

The electrolyte blend enhances hydration, which is vital during intense training or sports. This helps maximize performance.

Provides Antioxidants

Ingredients like green tea extract and Coenzyme Q10 provide antioxidants in Reign. Antioxidants help neutralize harmful free radicals and reduce oxidative stress caused by exercise.

This offers additional health and performance benefits.

Sugar-Free and Low Calorie

With zero sugar and just 10 calories per can, Reign can support fitness goals. The lack of sugar prevents energy crashes while the low calorie content fits into dietary requirements.

For athletes monitoring their nutrition and calories, Reign provides an energy boost without derailing diet plans.

Who is Reign Energy Drink For?

Athletes and Fitness Enthusiasts

Reign is designed for athletes and anyone living an active lifestyle. The combination of caffeine, BCAAs and electrolytes make it useful for fitness activities and sports.

It can provide fuel for intense training sessions as well as aiding workout recovery. The natural caffeine offers clean energy for physical performance without excessive sugar.


The caffeine in Reign delivers an energy boost, while BCAAs help reduce fatigue and support muscle recovery. This makes Reign useful as a pre-workout drink.

Many athletes and gym-goers drink Reign before their workouts to enhance performance and endurance.


After a tough training session, Reign can help refuel tired muscles. The BCAAs support muscle protein synthesis while electrolytes replenish what’s lost through sweat.

Drinking Reign after a workout helps you recover faster and get ready for the next training session.

Intermittent Fasting

For those practicing intermittent fasting, Reign offers an energy boost and workout fuel without disrupting the fasted state.

With zero sugar and minimal calories, Reign won’t spike insulin levels or break your fast like high-calorie drinks.

Keto Diet

The keto diet requires low carbohydrate intake to achieve ketosis. Reign contains zero sugar and only trace carbs, making it keto-friendly.

It can provide energy and workout fuel without interfering with ketosis or increasing carb intake.

Weight Management

Reign only contains 10 calories per can, allowing it to fit into a weight loss diet. The BCAAs help retain or build muscle when cutting calories.
