How Many Cans of Reign Can You Have a Day? (Facts)

Energy drinks are effective if you need a quick boost to fuel up your daily workout routine or extreme sports adventure.

Reign Energy contains 300mg caffeine and is by far one of the strongest energy drinks available alongside Bang, Raze, and G Fuel Cans.

Unless you have a very high level of caffeine tolerance, I personally recommend limiting your intake to only one can per day to be able to go about your daily activities normally. Even so, I don’t think you should be drinking Reign every day due to its high level of caffeine.

How Much Caffeine is in Reign?

A can of 16 fl.oz Reign Total Body Fuel contains 300mg caffeine, which is a massive amount for an energy drink. In my opinion, 50mg to 100mg is sufficient for one serving.

300mg caffeine in Reign
Reign Energy caffeine content is 300mg per can

Reign’s natural caffeine content is extracted from tea leaves, coffee beans, and other caffeine-based plants. Natural caffeine does not give you side effects such as insomnia, nervousness, and headaches as much as synthetic caffeine.

Caffeine has various health benefits, but not all of them have been confirmed by research. Some of the benefits include:

  • prevents weight gain
  • increased attention and alertness
  • improves exercise performance
  • enhances mental processes

Do keep in mind that drinking more than a can per day can lead to caffeine overdose. Some of the symptoms associated with caffeine overdose include:

  • headache
  • fever
  • insomnia
  • irritability
  • diarrhea
  • increased thirst

Reign’s caffeine content is quite close to the recommended 400mg intake per day set by the US Food and Drug Administration (FDA). It is still considered safe to consume a can of Reign Energy drink in a day as long as it is taken in moderation.

Does Reign Have Artificial Sweeteners?

The good news is, Reign is sugar-free. You don’t have to worry about a sugar crash as there is nothing in Reign that may raise your blood sugar and insulin level.

So where does Reign gets its sweetness from? It contains two zero-calorie artificial sweeteners, namely Acesulfame Potassium and Sucralose.

Acesulfame Potassium

Acesulfame potassium is an artificial sweetener that is around 200 times sweeter than sugar. It is used to sweeten food and drinks without adding calories and is often mixed with Aspartame and Sucralose to mask the bitter after-taste.


Sucralose is another ingredient found in Reign Energy. It is a zero-calorie artificial sweetener that is 400 to 700 times sweeter than sugar.

In some cases, Sucralose may increase the insulin levels of people who do not consume artificial sweeteners regularly. However, it may not have an effect on people who use artificial sweeteners regularly.

That being said, Sucralose is approved by health authorities and FDA does consider it safe.

Other Ingredients


The B-Vitamins found in Reign Energy are Vitamin B3 (Niacin), Vitamin B6 (Pyridoxine Hydrochloride), and Vitamin B12 (Cyanocobalamin).

You can easily get sufficient B-Vitamins in your diet, including through Reign Energy drink, so it is not necessary to supplement it further.

You can find B-Vitamins naturally in:

  • cheese
  • eggs
  • milk
  • liver and kidney
  • vegetables

The amount of B-Vitamins in Reign Energy and their respective benefits are presented in the table below:

Type of VitaminPurposeAmount per 16 fl.oz of ReignTolerable Upper Intake Level

Vitamin B6Forms red blood cells; store energy from carbohydrates and protein2.0mg100mg
Vitamin B12Formation of red blood cell; keeps the nervous system healthy; release energy from food6.25µg

Coenzyme CoQ10

Coenzyme 10 or CoQ10 in Reign Energy drink plays a key role in protecting cells from damage and can also improve metabolism.

Some of the benefits associated with CoQ10 include:

  • helps treat heart failure
  • better skin health
  • helps with fertility issues
  • improved exercise performance
  • reduces headache
  • could help with diabetes
  • improved mental function
  • manages chronic heart failure

Branched-Chain Amino Acids (BCAAs)

There are 1000mg BCAAs in a can of Reign Energy. The BCAAs found in Reign are L-Valine, L-Isoleucine, and Leucine. They are essential amino acids that are not produced in the body but are considered important components in your diet.

The 5 benefits of RCCAs are

  • increases growth of muscle
  • decreases soreness of muscle
  • reduces tiredness from exercise
  • prevents muscle wasting
  • improves health of people with liver disease

BCAAs are good for muscle health and help to decrease fatigue.

How Many Energy Drinks a Day is Considered as Safe?

Short answer: It heavily depends on the caffeine content of the particular energy drink.

Caffeine is one of the main concerns for energy drinks and it becomes more dangerous when mixed with alcohol.

So, it is important to know your energy drink’s caffeine content to avoid adverse effects and to ensure that it fits your needs.

Here are a few tips that can help:

  • read the label.
  • look for hidden ingredients.
  • note the caffeine content.

With the massive caffeine content in Reign, consuming more than one can a day is a bad idea. For instance, having 2 cans of Reign means you are consuming 600mg. It will definitely put you at risk of caffeine overdose and could be a danger to your health, especially when you have caffeine sensitivity issues.

Therefore, drink Reign Energy in moderation even if you think or believe that you need more.

Is Reign Energy Drink Healthy?

In my opinion, energy drinks are rarely healthy. Instead, it is intended to boost your energy, concentration, and alertness.

Reign Energy is a fitness-focused beverage packed with rich ingredients designed to give you the ultimate exercise performance.

It contains BCAAs, natural caffeine, Vitamin B3, B6, and B12 which are ingredients that bring positive benefits to your overall health.

Can You Drink Reign Energy Every Day?

At a glance, you’ll notice the massive caffeine content of Reign, which is the main reason why limiting your intake per day is a smart idea.

Drinking one can of Reign Energy daily is considered safe as long you don’t have any pre-existing conditions and caffeine sensitivity issues.

I think 300mg is a large amount of caffeine for an energy drink. It takes a healthy person and someone with high caffeine tolerance to down it without feeling any of the side effects.

If you want to stay healthier, limiting your intake of caffeinated drinks is wise. And make sure the overall caffeine intake in a day does not exceed the maximum limit stated by the FDA.

Final Thoughts

Reign is not bad at all, as long as you drink it responsibly.

Reign Energy is the perfect choice for a workout drink because it is capable of giving you enough energy to sustain your daily exercise.

I highly recommend only consuming one can per day for safety reasons. And if you have caffeine-related conditions, it is best to look for other alternative energy boosters.

However, if you’re healthy and in need of a quick boost, Reign Energy is a promising choice!
