C4 Energy Drink Caffeine Content

Before diving into the caffeine content of C4 Energy Drink, let’s have learn a few things about caffeine.

Caffeine is a substance, obtained naturally from various vegetation, that stimulates your brain. This stimulation helps you stay awake, prevents tiredness, and helps you focus. And during exercise, caffeine also prevents the running out of glycogen by stimulating muscles to burn fat. So you don’t get sore quickly.

And the daily limit for caffeine is 400mg per day for adults. Now have a look at this table:

Versions Caffeine Content (g)
C4 Original200
C4 Smart200
C4 Ultimate300
C4 Natural Zero150
C4 Energy Drink Caffeine Content

Except for C4 Natural Zero, all versions contain plenty of caffeine, closer or half to the daily limit. This drink might be right for you if you’ve grown a tolerance to low-caffeinated energy drinks or coffee.

But there’s always C4 Natural Zero if you’re not looking for that strong electricity throughout your veins. And there’s C4 Original and Smart Energy Drinks for moderate caffeine lovers.

But make sure to not have more than one can. There are many side-effects one can face from caffeine overdose:

  • Insomnia
  • Digestive issues
  • Muscle Breakdown
  • Anxiety
  • High Blood pressure
  • Fatigue

If you’re already familiar with Celsius Heat and Bang, C4 Ultimate’s caffeine content might not be shocking to you because it also has 300g of caffeine. Here are a few energy drink caffeine contents in comparison with C4 Energy Drink.

Artificial Sweeteners In C4 Energy Drink

Sucralose and Acesulfame Potassium are the two artificial sweeteners added in C4 Energy Drinks, to make the drinks sugar-free.

Artificial sugar has no nutritional value but they tend to be sweeter than natural sugar. And their use has been permitted by FDA, and according to them, they’re not supposed to be harmful.

Sucralose is 400-700 times sweeter than table sugar and doesn’t have a bitter taste, unlike other artificial sweeteners. Probably why it’s most common, even though the label doesn’t mention how much sucralose is present, Acceptable Daily Intake (ADI) for sucralose is 5mg per kilogram (kg) of body.

One health issue with sucralose is that it hampers the composition of normal gut flora which is responsible for preventing many diseases. Other than that, sucralose doesn’t affect insulin or blood sugar levels.

Acesulfame Potassium has a bit of a sour taste and is 200 times sweeter than table sugar. And the Acceptable Daily Intake (ADI) of Ace-K is 15mg per kg of body weight per day.

However, some findings have shown that ace-k might be associated with hamper blood sugar control, affect body weight, disrupt metabolic processes, and affect appetite.

Explosive Energy Blend Of C4 Energy Drink

“Explosion of both Physical and Mental energy”

Let’s have a look at the ingredients of 6.73mg of Explosive Energy Blend that claims to increase muscular endurance, retain hydration, and enhance physical performance.


N-Acetyl-L-Tyrosine is a chemical lookalike of Tyrosine. Tyrosine is an amino acid that can also be found in dairy products, meat, eggs or fish.

This amino acid is the building block for the protein that makes up chemical messengers. It makes the transfer of information to your brain and back faster.

Do you know those stressful moments when your brain isn’t just cooperating? Tyrosine helps to solve that. It keeps you alert and makes you focus better.

Citrulline Malate

Citrulline Malate or L-citrulline is an amino acid found in watermelon. It has many health benefits which are the reasons why it improves athletic performance:

  • Dilates blood vessels
  • Facilitates the distribution of nutrients to organs
  • Reduces blood pressure
  • Prevents heart diseases

More nutrients around your body means that you muscles don’t get tired easily.

But 2.4g to 5g of Citrulline Malate daily is required to observe significant changes. As we don’t know how much Citrulline Malate is present in C4 Energy Drink, we can’t be sure how much of the drink you have to consume to get proper results.

BetaPower® Betaine Anhydrous

Betaine Anhydrous is derived from sugar beets or molasses. It’s mainly required to keep the concentration of homocysteine low, which is an amino acid required for very metabolic activities.

Thus, it helps to maintain a healthy metabolism and maintain hydration level of the body.

But this component is also required to be consumed in the right amount for a longer time in order to achieve that sort of regulation. So, without properly knowing its concentration in the energy blend, we can’t be too sure of its function.

CamoSyn® Beta-Alanine

Beta-Alanine is a non-essential amino acid that can be converted to some other components required by muscles.

It has been blended to improve work-out performance by delaying fatigue of your muscles. Intake of beta-alanine increases the formation of carnosine that helps your muscles to reduce lactic acid levels during exercise.

Normally you’d need a dosage of up to 2.4g to 6.4g for over 2 months to observe any athletic improvements.

What Does C4 Energy Drink Taste Like?

C4 Energy Drink taste like fruit slushies depending on the flavor. It’s a carbonated drink with 200mg of caffeine. This drink’s actually good because it gives you a refreshing sparkling water effect and not like the usual energy drink.

C4 Energy tastes like fruit slushies depending on the flavor.

This drink gives you a tropical vibe with its fruit ingredients, which you can actually taste when you drink. And given the fact that it’s sugar-free, it tastes really sweet to satisfy your taste buds.

I definitely recommend you to try this product because aside from its taste, it’s also budget-friendly. A reminder to drink this once a day together with a proper diet and exercise.
