Reign Storm has built a strong position in the zero-sugar energy drink market by combining 200 mg of caffeine with plant-based ingredients, B vitamins, biotin, zinc, chromium, and botanical extracts. The drink targets people who want energy and focus without the higher caffeine dose found in traditional REIGN Total Body Fuel.
But does Reign Storm actually offer a better energy experience? Does its plant-based caffeine make a meaningful difference? And can you use it as a pre-workout?
This guide breaks down Reign Storm energy drink, its caffeine content, ingredients, nutrition profile, flavors, potential benefits, possible side effects, and best uses. It also compares Reign Storm with REIGN Total Body Fuel and Celsius so you can decide which option fits your routine.
Important: Product formulas and labels can change. Always check your can for the most current ingredient and nutrition information.
What Is Reign Storm Energy Drink?
REIGN Storm is a zero-sugar energy drink that combines caffeine with botanical extracts, vitamins, minerals, and flavor ingredients. The current product line includes flavors such as Kiwi Blend, Guava Strawberry, Valencia Orange, Harvest Grape, Peach Nectarine, and other varieties.
A 12 fl oz can provides 200 mg of caffeine from all sources. Product labeling describes its caffeine as part of a proprietary plant-based energy blend that includes green tea extract, ginseng, guarana, and guayusa.
Reign Storm also provides a vitamin and mineral blend that includes:
- Vitamin A
- Vitamin C
- Vitamin B3
- Vitamin B5
- Vitamin B6
- Vitamin B7 (biotin)
- Vitamin B12
- Zinc
- Chromium
The product contains zero sugar and only about 10 calories per can on the referenced nutrition labels.
Who Should Consider Reign Storm?
Reign Storm can suit adults who want:
- A moderate-to-high caffeine boost
- Zero added sugar
- A smaller 12 oz can
- Plant-derived caffeine sources
- Vitamins and minerals alongside caffeine
- A drink for morning productivity or exercise
However, the 200 mg caffeine dose still packs a substantial stimulant effect. People who react strongly to caffeine should approach the drink carefully.
Reign Storm Caffeine Content: How Much Caffeine Does It Have?
Reign Storm contains 200 mg of caffeine per 12 fl oz can. The label states that the caffeine comes from all sources.
That amount makes one can a significant part of an adult’s daily caffeine intake.
The FDA cites 400 mg of caffeine per day as an amount that generally does not associate with negative effects for most healthy adults. However, caffeine sensitivity varies based on factors such as body weight, medications, health conditions, and individual metabolism.
How Much Caffeine Does Two Cans Provide?
Two cans would provide:
200 mg × 2 = 400 mg of caffeine
That reaches the FDA’s general daily reference level for most healthy adults.
However, you must count caffeine from every source. Coffee, tea, pre-workout supplements, soda, chocolate, and other energy products can increase your total.
Does Plant-Based Caffeine Work Differently?
Reign Storm markets its caffeine as plant-based because its formula includes botanical caffeine sources such as green tea, guarana, and guayusa.
However, your body still responds to the caffeine molecule itself. The FDA notes that your body handles naturally occurring caffeine from coffee and tea similarly to caffeine added to products.
Therefore, you should not assume that plant-based caffeine automatically produces a slower or smoother effect.
The overall experience can depend on the complete formula, your caffeine tolerance, what you eat with the drink, and your individual response.
Reign Storm Clean Energy Ingredients Explained
Reign Storm uses several botanical and nutritional ingredients. Let’s examine the major components.
Green Tea Extract
The formula contains green tea extract standardized to 45% EGCG on the product ingredient list.
EGCG stands for epigallocatechin gallate, a catechin found naturally in green tea.
Green tea extract can contribute antioxidant compounds to the formula. It also appears in the product’s plant-based energy blend.
However, you should not interpret the presence of EGCG as proof that the drink will produce significant fat loss.
Guayusa Extract
Guayusa comes from the leaves of Ilex guayusa, a plant native to the Amazon region.
Reign Storm includes guayusa extract as part of its proprietary plant-based energy blend.
Guayusa naturally contains caffeine, so it contributes to the overall stimulant profile.
Guarana Extract
Guarana also contributes naturally occurring caffeine.
Reign Storm lists guarana alongside green tea extract, ginseng, and guayusa in its plant-based energy blend.
Because the label reports 200 mg of caffeine from all sources, you should consider the total caffeine rather than trying to calculate the caffeine contribution of each botanical individually.
Panax Ginseng
Reign Storm includes Panax ginseng extract.
Ginseng has a long history of use in traditional medicine, and researchers have studied its potential effects on fatigue, cognition, and physical performance.
However, the presence of ginseng in an energy drink does not automatically prove that the drink will improve athletic performance or reduce fatigue.
Zinc
Zinc contributes to several normal physiological functions, including immune function.
Some Reign Storm labels provide 50% of the Daily Value for zinc per can.
That makes the drink more than a simple caffeine-and-flavor beverage, but you should still avoid treating it as a replacement for a balanced diet.
Chromium
Reign Storm also contains chromium picolinate.
Referenced labels list 100% of the Daily Value for chromium per can.
Chromium plays a role in normal nutrient metabolism. However, you should not interpret the amount in an energy drink as a guarantee of weight loss or enhanced fat burning.
B Vitamins and Biotin
Reign Storm provides several B vitamins, including:
- Niacin
- Pantothenic acid
- Vitamin B6
- Biotin
- Vitamin B12
Some labels list 100% of the Daily Value for several of these vitamins.
These nutrients support normal metabolic processes, but taking more does not necessarily create more energy when you already meet your nutritional needs.
Reign Storm Sweeteners: Sucralose and Erythritol
Reign Storm formulas can include sweeteners such as sucralose and erythritol, depending on the flavor and current formulation.
Erythritol belongs to the sugar alcohol family. Some people tolerate it well, while others can experience digestive discomfort after consuming larger amounts of sugar alcohols.
Sucralose provides sweetness without adding conventional sugar.
Can Reign Storm Cause Digestive Problems?
Some people may experience:
- Bloating
- Gas
- Stomach discomfort
- Loose stools
Individual tolerance varies.
If you notice digestive symptoms after drinking Reign Storm, try reducing your serving frequency or choosing a beverage with a simpler sweetener profile.
Does Reign Storm Accelerate Metabolism?
Reign Storm markets its formula around metabolism support. Its labeling also states that its proprietary energy blend can help boost metabolism and that exercise and a healthy diet can contribute to fat burning. The label specifically states that the product alone does not produce weight loss.
That distinction matters.
Caffeine can increase energy expenditure in some circumstances, while green tea compounds have also received extensive research attention. However, you should not treat an energy drink as a standalone fat-loss solution.
Can Reign Storm Help With Weight Loss?
Not by itself.
Weight management depends on overall energy intake, physical activity, sleep, dietary patterns, and many other factors.
Reign Storm can provide caffeine without sugar, which may make it easier to avoid sugary beverages. That does not make the drink a weight-loss supplement.
Is Reign Storm Good for Pre-Workout?
Reign Storm can work as a pre-workout caffeine source for some adults.
One can provides 200 mg of caffeine, which gives you a substantial stimulant dose before exercise.
You may prefer it when you want:
- Energy before training
- Increased alertness
- A zero-sugar option
- A ready-to-drink alternative to powdered pre-workout
- A smaller can than traditional REIGN Total Body Fuel
However, you should consider your total daily caffeine intake before using it.
When Should You Drink Reign Storm Before a Workout?
Many people consume caffeine before exercise because caffeine can affect alertness and perceived effort.
A practical approach involves drinking it roughly 30–60 minutes before training, then adjusting based on your individual response.
Avoid taking it too close to bedtime because caffeine can interfere with sleep.
Reign Storm vs. Reign Total Body Fuel
The two products target different use cases.
REIGN Total Body Fuel provides 300 mg of caffeine in a 16 oz can, according to the brand’s product information.
Reign Storm uses a smaller 12 oz format with 200 mg of caffeine.
| Metric | Reign Storm | REIGN Total Body Fuel |
|---|---|---|
| Can size | 12 fl oz | 16 fl oz |
| Caffeine | 200 mg | 300 mg |
| Sugar | 0 g | 0 g |
| Main positioning | Clean energy and active lifestyle | High-performance energy |
| Botanical ingredients | Green tea, ginseng, guarana, guayusa | Different performance-focused formula |
| Best fit | Moderate caffeine users | People seeking a stronger caffeine dose |
Which One Should You Choose?
Choose Reign Storm if you prefer a lower caffeine dose and a 12 oz can.
Choose REIGN Total Body Fuel if you deliberately want 300 mg of caffeine and tolerate higher stimulant doses well.
The higher caffeine dose does not automatically make Total Body Fuel better.
Reign Storm vs. Celsius
Reign Storm and Celsius both appeal to people who want zero-sugar energy drinks with a fitness-oriented image.
| Feature | Reign Storm | Celsius |
|---|---|---|
| Typical caffeine | 200 mg | Often 200 mg |
| Sugar | 0 g | 0 g in many core products |
| Key positioning | Plant-based energy + metabolism support | Fitness and active lifestyle |
| Botanical ingredients | Green tea, guarana, guayusa, ginseng | Product-specific blend |
| Can size | 12 fl oz | Varies by product |
| Best for | People who like stronger flavor variety and vitamin/mineral additions | People who prefer Celsius’ flavor lineup |
Always check the individual can because formulas and serving sizes can vary between product lines.

Can You Drink Reign Storm While Fasting?
Reign Storm contains zero sugar, but zero sugar does not automatically mean zero calories or zero metabolic impact.
Some versions contain about 10 calories per can, and ingredients such as sweeteners can also affect how different people experience fasting.
If you follow fasting for religious, medical, or specific metabolic reasons, follow the rules of your fasting protocol rather than assuming that every zero-sugar energy drink qualifies.
For strict fasting, water often provides the simplest option.
Is Reign Storm Keto-Friendly?
Reign Storm can fit into some low-carbohydrate diets because it contains zero sugar and only a small amount of carbohydrate on referenced labels.
However, keto suitability depends on your individual carbohydrate target and the exact product formula.
Always check the current nutrition label before adding it to your diet.
Does Reign Storm Cause a Caffeine Crash?
Reign Storm can cause a perceived energy crash in some people, but the effect varies.
Caffeine can temporarily increase alertness and reduce the perception of fatigue. As its effects decline, you may notice tiredness, especially if you already lack sleep.
You may also experience a stronger rebound if you:
- Consume too much caffeine
- Drink several caffeinated products
- Use caffeine late in the day
- Depend on caffeine to compensate for poor sleep
- Have a high caffeine sensitivity
The plant-based origin of the caffeine does not guarantee a crash-free experience.
Reign Storm Side Effects
Most healthy adults can tolerate moderate caffeine intake, but caffeine affects people differently.
Potential effects from excessive caffeine can include:
- Jitters
- Nervousness
- Increased heart rate
- Headache
- Upset stomach
- Nausea
- Sleep disruption
- Anxiety
- Palpitations
The FDA lists these among potential effects associated with excessive caffeine consumption.
Reign Storm’s own labeling also advises against consumption by children, pregnant or nursing women, and people who are sensitive to caffeine.
If you develop severe or unusual symptoms after consuming a caffeinated product, seek appropriate medical advice.
How to Use Reign Storm Responsibly
You can reduce your risk of excessive caffeine intake by following a few simple practices.
1. Track Your Total Caffeine
Count caffeine from:
- Coffee
- Tea
- Energy drinks
- Pre-workout products
- Caffeinated soda
- Supplements
- Other caffeinated foods and beverages
One Reign Storm already supplies 200 mg.
2. Avoid Stacking Stimulants
Do not automatically combine Reign Storm with a high-caffeine pre-workout.
That combination can push your daily caffeine intake much higher than you intended.
3. Consider Your Sleep Schedule
Avoid caffeine close to bedtime if it interferes with your sleep.
A strong energy boost cannot replace adequate sleep.
4. Start With Your Personal Tolerance
If you rarely consume caffeine, 200 mg may feel much stronger than it does for a regular caffeine user.
The FDA emphasizes that caffeine sensitivity varies significantly among individuals.
Our Testing Methodology for Reign Storm
A genuine biometric review requires actual measurements. You should not present simulated results as laboratory findings.
For a future first-party test, you can use the following protocol.
120-Minute Energy and Focus Test
Track:
- Resting heart rate
- Heart-rate response
- Subjective energy
- Focus
- Jitters
- Blood glucose, if appropriate
- Perceived fatigue
Record measurements at:
- 0 minutes
- 30 minutes
- 60 minutes
- 90 minutes
- 120 minutes
You can then compare Reign Storm against a control beverage.
Thermogenic Performance Test
A properly controlled exercise study could compare Reign Storm with water during steady-state exercise.
Researchers could measure:
- Oxygen consumption
- Carbon dioxide production
- Respiratory exchange ratio
- Calories burned per minute
- Exercise heart rate
- Perceived exertion
However, you should only call the results original laboratory data if you actually conduct the testing under a valid protocol.
What the Evidence Can and Cannot Tell Us
Reign Storm contains several ingredients that researchers have studied independently.
That does not mean researchers have proven that the complete Reign Storm formula produces every benefit claimed by marketing materials.
You should separate three things:
- Ingredient evidence — research on an individual ingredient.
- Formula evidence — research on the specific combination.
- Product evidence — controlled research on the finished beverage.
The third category provides the strongest evidence for claims about the actual product.
Without controlled product-specific trials, you should avoid claiming that Reign Storm definitely improves fat loss, metabolism, athletic performance, or cognitive function.

- 200 mg caffeine
- Zero sugar
- A 12 oz can
- Fruit-focused flavors
- Added vitamins and minerals
- A ready-to-drink pre-workout alternative

Final Verdict: Should You Try Reign Storm?
Reign Storm takes a different approach from high-caffeine performance energy drinks. It delivers 200 mg of caffeine in a 12 oz, zero-sugar format and combines that caffeine with green tea extract, ginseng, guarana, guayusa, vitamins, zinc, chromium, and biotin.
Its biggest advantage comes from its balance. You get a meaningful caffeine dose without jumping straight to the 300 mg found in REIGN Total Body Fuel.
If you want a zero-sugar energy drink for morning productivity, active days, or pre-workout use, Reign Storm can make a practical choice.
However, you should not confuse marketing claims about metabolism or plant-based energy with proof of superior fat loss or performance. The caffeine still counts toward your daily intake, and individual tolerance matters.
For most healthy adults, the best approach involves treating Reign Storm as a caffeinated beverage rather than a health supplement. Check the label, track your total caffeine, protect your sleep, and choose the flavor that fits your taste.
