Calories in Reign Energy Drink

Reign energy drink has only ten calories, a very low amount compared to other calorie-filled energy drinks.

A calorie is a unit of Energy obtained through daily foods and beverages. It is essential for us as it helps in the proper functioning of the body organs. However, too much calorie consumption can be bad for you. Therefore, it is advised that you should limit yourself to 2000-2500 calories in a day to avoid any side effects.

Reign energy drink is completely calorie-free.

Reign Energy drink contains only ten calories which is very few compared to other calorie-filled energy drinks. So, if you are not big on sugary energy drinks, then Regin is perfect for you.

Moreover, even though this energy drink has low calories, it will still energize you because of its amazing caffeine content. So, Regin energy drink is a healthy option of energy drinks and will not cause any consequences if you consume it in moderate amounts. 

But remember, since this energy drink has only ten calories, you won’t be able to obtain actual Energy from it. Therefore, eat actual food and don’t substitute this with your daily food intake.

Caffeine in Reign Energy Drink

Reign energy drink contains 300mg of caffeine in its formula, which can be too much for some people.

Caffeine found in Reign energy drinks is completely derived from green tea leaves and coffee beans. However, even though the caffeine present in this energy drink is natural, it is still more than the other energy drinks. 

The FDA has recommended that you only consume up to 400mg of caffeine. Even though the amount of caffeine present in Reign is within the daily recommended amount, drinking one can of this energy drink within one go is alarming.

The reason behind this is that the amount of caffeine you would get from one serving of Reign would be equivalent to an entire day.

Too much caffeine intake can be hazardous to your health and can cause the following side effects:

  • Anxiety
  • Insomnia
  • Digestive Issues
  • Heartburn
  • Muscle Tremors
  • Nervousness
  • High Blood Pressure
  • Caffeine Addiction

While Reign is a good choice for calories and sugar, it still has high caffeine content. Therefore, I will recommend that if you have this energy drink, try to drink only one can a day too in intervals. Furthermore, if you are caffeine sensitive, avoid this energy drink altogether.

Sugar in Reign Energy Drink

Reign energy drink is completely sugar-free. 

Sugar is the main ingredient present in almost every energy drink as it provides you with Energy. However, this Energy is not permanent and can cause crashes and make you feel jittery if you consume too much of it.

Furthermore, too much sugar is also bad for you in general and can cause side effects like:

  • Headaches
  • Jitters
  • Crashes
  • Obesity
  • Weight Gain
  • High Blood pressure
  • Tooth Decay
Here are some of the side effects of too much sugar.

Therefore, AHA has said that you should always restrict yourself to 25g to 36g of sugar in a day as it is a healthy amount.

Reign energy drink does not have any sugar in its formula, so you won’t have to worry about these side effects.

Artificial Sweeteners in Reign Energy Drink

Reign Energy Drink uses sucralose and acesulfame-k as its artificial sweeteners.

Artificial sweeteners are a good sugar substitute and are completely safe to use. Many energy drinks use artificial sweeteners instead of actual sugar to avoid adding extra calories.

Sucralose and Acesulfame-K are the sweeteners present in this energy drink. Sucralose is a non-nutritive and no-calorie sweetener and is 600 times sweeter than actual sugar. Whereas, Ace-k is 200 times less sweet than sugar and calorie-free.

Furthermore, both of these artificial sweeteners are safe to consume. But remember to have them in moderate amounts.

Is Reign Energy Drink Healthy?

The ingredients in all energy drinks are designed to provide immediate Energy and refreshment, but they might not be the best for your overall health. Due to its low-calorie content and natural ingredients, Reign Energy Drink may be a safer choice for you.

Reign Energy does not contain sugar and calories, making it a good choice for energy drinks.

Furthermore, it contains ingredients that can improve your overall health and give you a boost of energy.

Nevertheless, there are still some ingredients that may not exactly be healthy. Reign Energy contains a relatively high amount of caffeine, which, if consumed excessively, may harm your health.

Reign Energy is not that healthy compared to water or freshly squeezed juice. However, if consumed in moderation, it can increase your energy and enhance your mental and physical performance.

Is Reign Energy Drink Bad For You?

Reign Energy Drink is not bad for you as long as you consume it according to the recommended levels. Nonetheless, if you are caffeine sensitive, you should maintain caution due to its high caffeine content.

The only problem with Reign Energy Drinks is that they contain a high amount of caffeine. While it might help with boosting your pre-workout performance, drinking too much of it at once might cause some negative effects.

These side effects are:

  • Sleeping Difficulty or Insomnia
  • Excessive Energy and restlessness
  • Sudden loss of Energy
  • Jitteriness

Reign’s 300mg caffeine might not be for everyone, but you’ll be fine as long as you take it in moderate amounts.

How Many Cans Of Reign Energy Can You Have In A Day?

Reign energy drink contains a high amount of caffeine in its formula, which, if consumed in high amounts, can cause side effects. Therefore, you should restrict yourself to one can of this energy drink per day.

Reign Energy(16 fl.oz)Daily Max Limit(Female/Male)
Calories0 calories2400 calories/3000 calories
Sugar0g25g / 36g
A can of Reign energy drink contains zero sugar, calories, and 300mg of caffeine.

As you can see from the above table that the calorie and sugar content of Reign is completely zero, which means you won’t have to worry about it at all. However, the main concern is the caffeine present in this energy drink powder which is 300mg.

When it comes to caffeine, 300 mg is a lot, especially for hypersensitive people. There is a recommended daily limit of 400mg for adults, so that amount is close to it.

Thus, Reign Energy can only be consumed once per day. Assuming you consume two cans every day, you would be consuming 600mg of caffeine every day, which exceeds the recommended daily limit and causes side effects.

Does Reign Make You Gain Weight?

Reign Energy Drinks include no sugar, making them the most sugar-free energy drink available. So, drinking it does not make you gain weight.

As a reminder, the American Heart Association recommends a daily sugar intake of no more than 25 g for women and 36 g for men. As a result, exceeding the recommended daily consumption can result in weight gain.
