Maybe you’ve taken a liking to C4 Energy Drink and have noticed that it’s becoming an increasingly common feature in your daily life.

Wondering whether it’s even safe to drink C4 on a daily basis?

You’re in the right place!

If you just want a quick answer to this question, the answer is that it’s perfectly fine to drink C4 Energy Drink every day as long as you consume them in moderation and you don’t have any other health issues.

But, there’s a whole lot more to talk about and consider in understanding why that’s the case, so let’s dive in.

Let’s get started…

What Is C4 Energy Drink?

Cellucor is a global leader in sports nutrition and the proud maker of one of America’s best-selling pre-workout brands, C4.

The brand established its product range in 2011, with a line-up of pre-workout supplements, whey protein powders, testosterone boosters, and weight loss capsules.

Fast forward to the spring of 2018, the brand dived into the world of energy drinks with its “On The Go” C4 Energy Carbonated drink.

The energy drink venture brings you four interesting collections, namely: Original, Smart Energy, Ultimate, and Natural Zero.

As much as the C4 brand sounds like a dream come true for avid energy drinkers, you might still be concerned about how advisable it is to consume C4 every day.

You might also wonder about the impacts of C4 on your overall health.

Well, not to worry, I’ve put this post together to help give you a deeper understanding of what C4 energy drinks are really made of, and how the drinks might affect your health for better or for worse.

Let’s get the ball rolling with a quick glance at what’s inside each version of C4 energy drinks.

C4 Energy drinks contain 120mg to 300mg of caffeine, depending on which product you choose.

The average cup of coffee contains about 95mg of caffeine. Compare that to the 120mg of caffeine in the lightest C4 energy drink like Natural Zero, and you might see that it contains a decent serving of caffeine.

However, C4 Ultimate with a monstrous 300mg of caffeine to its name might be on another level completely, as compared to its sister products.

Indeed, this caffeine punch puts it in the league of the world’s strongest energy drinks.

The extremely high caffeine content might remind you of another well-known giant in the energy drink industry, Bang.

If you know Bang at all, you might be aware of the potential side effects that come from consuming too much caffeine.

Some of the side effects that you may experience from drinking too much caffeine include:

  • anxiety
  • insomnia
  • digestive issues
  • muscle breakdown
  • addiction
  • high blood pressure
  • rapid heart rate
  • fatigue
  • loss of bladder control

According to the FDA, you’re recommended to stick to a caffeine dosage of not more than 400mg per day.

If you’re doubtful of not getting a good energy kick from energy drinks with lower caffeine, C4 energy drinks might be right for you.

C4 energy drinks are enhanced with stimulating blends that come from the laboratory of the manufacturer, Nutrabolt.

C4 Original has 5g of “Explosive Energy Blend” with ingredients including beta-alanine, arginine nitrate (NO3-T), and N-acetyl-l-tyrosine.

When 200mg of caffeine anhydrous is added to the blend, the drink turns into a supplement that ‘delivers explosive energy for your demanding lifestyle‘. (a line I lifted off from the back of the can)

Label on C4 energy drink
Two cans of C4 Original per day is pretty safe for your health.

C4 Ultimate contains 708g C4 Ultimate Energy & Focus Blend, that consists of: n-acetyl-l-tyrosine, alphasize A-GPC, Zembrin, Rauwoflia Vomitoria root extract, and Huperzine A.

With 300mg of caffeine anhydrous thrown into the mix, you can expect an energy-packed booster that gets you bouncing off the wall in no time.

So, always be mindful of not consuming too many C4 energy drinks, no matter how much caffeine is in the particular C4 variant that you choose.

Do C4 Energy Drinks Have Side-Effects?

If you drink too many C4 energy drinks you may experience some side effects. The same is true of any energy drink though. C4 is no better or worse than any other energy drink in my opinion.

If you go overboard with energy drinks, you might encounter these side effects:

  • Caffeine overdose
  • Type 2 diabetes
  • Adverse neurological effects (in adolescents and children)
  • Obesity

Luckily for you, C4 energy drinks are sugar-free. So, it’s unlikely that you’re at risk of developing type 2 diabetes or obesity.

The sugar in C4 energy drinks is replaced with artificial sweeteners. While they make healthier substitutes, there’s a certain limit to the artificial sweeteners.

In terms of sucralose, which is used in C4 energy, it’s advisable to limit yourself to just 9mg per kg of your body weight per day.

For instance, if you weigh 50kg (110 lbs), it’s safe for you to consume up to 450mg of sucralose in a single day.

When it comes to ace-K, you can have up to 15mg per kg of body weight within a day.

Should you exceed the Acceptable Daily Intake (ADI) amounts of either sucralose and or Ace-K, here are some of the side effects you might end up experiencing:

  • Headaches
  • Diarrhea
  • Respiratory problems
  • Dizziness
  • Nausea
  • Digestive problems
  • Bloating 
  • Allergies
  • Mood swings 
Get to know the sweet things in your energy drinks.

Caffeine overdose might not be a problem for you as long as you stick to no more than two cans of C4 within 24 hours. That’s what’s recommended on the back of the can as well.

You might want to stick to one can of C4 Ultimate in a day though, since the drink is packed with 300mg of caffeine.

I recommend that you to stick to only one or two cans of C4 each day, just to be on the safe side.

Is It Safe To Drink C4 Energy Drink Everyday?

In my opinion, I think that it’s safe to drink C4 energy drinks everyday as long as you consume them in moderation.

And, by moderation, I mean not more than two servings per day, as printed on the back of every C4 energy drink can.

There are certain precautions to take note of, so that the drinks don’t pose a threat to your health and well-being.

And, all these warning notes come from the back of the can, so you can check them out for yourself too.

The drinks are only intended for healthy adults, that means those of 18 years of age or older. Pregnant and/or nursing mothers should also avoid them.

If you’re taking any prescription drug or over-the-counter medication, consult your doctor before drinking C4 drinks. Better to be safe than sorry.

I personally think that any energy drink is unsafe for anyone who has been diagnosed with a serious medical condition. But, check with your healthcare professional before making the decision to introduce C4 into your daily routine.

Here’s another important thing to note: Don’t consume other caffeine sources alongside any of the C4 products.

The drinks are already loaded with stimulating blends of energy-boosting ingredients and ample caffeine. So, it might be better for you to stay away from other caffeinated foods and drinks for a bit.

It’s suggested that you consume one can of the drink at least 20 to 30 minutes before you get to your workout session or carry out your daily routine.

Also, it’s probably a smart idea to NOT drink any C4 within about 6 hours of planning to sleep so that you can get a good night’s sleep instead of tossing and turning from having caffeine too close to going to bed.

But, getting back to the main point which was whether or not it’s safe to drink C4 every day, I think we can agree on this…

It’s perfectly safe to drink C4 Energy Drink every day as long as you don’t have a pre-existing health condition, follow the warnings and recommendations listed on the can, and limit yourself to a maximum of only 1 or 2 cans per day.

Where To Buy C4 Energy Drinks And How Much Are They?

C4 energy drinks are widely distributed in the US. You can easily purchase them in any physical stores nationwide.

For some people, the convenience of buying online is better than heading down to your local store. Just remember to factor in shipping costs if you plan to shop online for your C4.

You’ll find a price tag that ranges from around $2.50 to $3 per can of C4 energy drink, depending on the version and where you find it.
