Now, let’s check these nutritional facts in detail.

Calories in C4 Energy Drink

The C4 energy drink has zero calories present in its formula.

Calories are a crucial form of energy, and it makes up half of your body and helps in the functioning of many organs. However, too many calories are still bad for you as they can lead to side effects like weight gain and obesity. Therefore, whenever you consume calories, make sure you consume only 2000-2500 calories in a day as it is the safest amount according to the NHS.

The C4 energy drink has zero calories in its formula, which means it is perfect for those trying to lose weight but can’t go through their day without energy drinks.

However, remember whether energy drinks have calories or not; you should always consume them in moderate amounts.

Caffeine In C4 Energy Drink

C4 energy drink contains only 200mg of caffeine in its formula.

Caffeine is a crucial ingredient of every energy drink as it is a main source of energy. Besides this, it also provides you with benefits like improving your alertness, increasing your mental and physical performance, giving you an immediate and keeping you awake throughout the day.

C4 energy drinks have moderate caffeine content.

However, too much caffeine is not good for you and can cause caffeine overdose. You can also experience other side effects like nausea, headache, insomnia, depression, anxiety, etc. If you don’t stay within limits, 400 mg per day as set by the FDA.

The good news is that this energy drink contains only 200 mg of caffeine which is half of the daily recommended amount. That means you can easily have this energy drink without worrying about any side effects.

However, remember not to overdo it, especially if you are caffeine sensitive.

Sugar in C4 Energy Drink

C4 energy drink contains zero sugar in its formula.

Sugar is another ingredient present in energy drinks to add taste to them. However, too much sugar is not good for you, especially if you have diabetes. Furthermore, it can also cause side effects like weight gain, obesity, crashes, jitters, headaches, etc., if you consume too much.

Therefore, always try not to exceed the daily sugar intake of 25 to 36 g of sugar in a day.

Fortunately, this energy drink does not have any sugar in its formula and only uses artificial sweeteners to add taste to the drink. This means you won’t have to worry about any negative side effects and can enjoy this energy drink.

Artificial Sweeteners in C4 Energy Drink

The artificial sweeteners in C4 energy drinks are sucralose, stevia, and acesulfame-k.

C4 energy drink is completely sugar-free and uses artificial sweeteners in its formula. These artificial sweeteners are a good sugar substitute and are completely free from side effects. Let’s check this sweetener in detail.


Sucralose, or as we call it, Splenda, is a non-nutritive sweetener. It is used in every energy drink and is completely calorie-free. Moreover, this sweetener is 700 times sweeter than actual sugar.

Furthermore, unlike sugar, this artificial sweetener does not spike your blood pressure making it suitable for diabetics patients. But, remember, no matter how much this sweetener is beneficial, you should always consume it in moderate amounts as its side effects are unknown.

Review of C4 energy drink.

Can You Drink C4 Energy Drink Every Day?

Yes, you can have a C4 energy drink every day if you consume it in moderate amounts.

It has no sugar or calories, and its caffeine content is half of the recommended daily amount. Despite this, it isn’t a good habit to consume energy drinks daily.

Even though you can drink it every day, that doesn’t mean you should. It’s packed with vitamins and minerals, and because it contains a lot of caffeine, it provides an immediate boost.

Nevertheless, its caffeine content also makes regular consumption of it not recommended. The best thing to do instead is to drink C4 as needed. As a result, you can eat a more balanced diet without worrying about caffeine overdose.

How Many Cans of C4 Energy Drink Should You Have in A Day?

It would help if you only drank up to one can of this energy drink daily.

The C4 energy drinks contain a lot of caffeine; therefore, try to restrict yourself to one can of this energy drink daily. 

Depending on which variation you choose, C4 energy drinks can contain caffeine levels ranging from 120mg to 300mg. Go for the one you know your body can handle when choosing a version. I have added a table below to show the caffeine present in the different versions of the C4 energy drink.

4 VariantsCaffeine content
Smart Energy200mg
Natural Zero120mg
Here are four variants of the C4 energy drink.

You are more likely to develop caffeine overdose symptoms if you consume more than one can of C4 energy drink each day.

You should be aware that too much caffeine can cause side effects. Watch this video to learn how caffeine helps us feel awake.

Is It Bad To Drink C4 Without Working Out?

It’s a caffeine-based pre-workout with additional compounds that contribute to the overall effect.

Simply said, this isn’t a caffeine supplement. It’s a pre-workout supplement that helps you increase your performance. The goal is to increase your alertness, attentiveness, and workout results.

However, because of its broad application, it has become a general-purpose supplement. It can be used regardless of your performance goals or training style: it’s all-encompassing and doesn’t have to be limited to a single type of exercise or aim.

How Long Does C4 Energy Drink Last In Your System?

It is ultimately determined by how well your body reacts to the 200mg of caffeine included in a 16-ounce can of C4 Energy drink.

Caffeine’s effects are usually felt within 15 to 30 minutes of ingestion. For most people, it reaches a peak after an hour and remains there for several hours.
Because of the half-life characteristic of caffeine, the 100mg of caffeine in C4 Energy will last roughly five to six hours in your system. The remaining half will take another 12 hours to eliminate.

Is C4 Stronger Than Red Bull?

When compared to prominent energy drink brands like Red Bull, C4 Energy comes out on top in terms of calories and sugar.

If your body can withstand 200mg of caffeine, the C4 Energy drink will benefit you more. To avoid the risk of caffeine overdose, don’t consume more than two cans of this drink in one day.

The 200mg of caffeine in a 16 fl. oz can of this drink is, however, its worst flaw.
