Does C4 Energy Drink Have Too Much Caffeine?

C4 energy drink contains around 120mg to 300mg of caffeine depending on the product line of the beverage. It’s more of a moderate to high amount as most energy drinks on the market contain between 50mg to 300mg of caffeine.
C4 Original and Smart Energy versions contain around 200mg of caffeine which is a decent amount to have in an energy drink. However, C4 Ultimate contains 300mg of caffeine which makes it one of the strongest energy drinks.
Whether you consume C4 Original or C4 Ultimate, you shouldn’t consume more than one can.
Otherwise, you may experience the side effects of caffeine overdose, including:
- diarrhea

- irritability
- headache
It can even lead to serious symptoms such as trouble breathing, chest pain, fast heartbeat, and vomiting. If you experience any of these, then you should seek medical attention as soon as possible.
Are The Artificial Sweeteners In C4 Energy Drink Vegan?
C4 energy drink has two artificial sweeteners named Ace-K and sucralose. These sweeteners are non-nutritive, and they’re around 200 to 600 times sweeter than sugar.
Ace-K is made using a naturally occurring mineral and other organic ingredients. This sweetener is 100% vegan-friendly.
Sucralose is made using a chemical process from table sugar. For this reason, its taste is closest to sugar.
While sucralose is made in chemical labs, there are some concerns that sucralose was actually tested on animals.
Sucralose doesn’t have any animal derivatives. While sucralose is made in chemical labs, there are some concerns that sucralose was actually tested on animals.
These artificial sweeteners are approved by the U.S. Food and Drug Administration for general use. However, you shouldn’t consume too much of these sweeteners to stay healthy.
Is C4 Energy Drink Keto-Friendly?
C4 energy drinks are suitable for your keto diet. C4 energy drink doesn’t contain any sugar or calories. Its artificial sweeteners are also calorie-free.
On keto diets, you need to have a low amount of carbs, and a high amount of fats. It’s most likely to help you lose weight and to control pre-existing medical conditions like type 2 diabetes.
Therefore, C4 energy drink is a great fit for a keto diet. Even if you’re not following a keto diet, it can always down a can of C4 to perform better in your workouts.
Is C4 Energy Drink Gluten-Free?

Based on the ingredients label, C4 energy drink doesn’t have any ingredient that contains gluten.
Gluten’s a protein found in grains like wheat, oats, rye, and barley. People with celiac disease and gluten intolerance cannot consume food or beverages that contain gluten.
If they consume gluten, they might encounter these problems:
- bloating
- diarrhea
- fatigue
- intestinal damage
- malnutrition
While there aren’t any ingredients that actively contain gluten, there’s a slight chance that the company can use gluten-based products on the same equipment. That’s why you should reconsider before buying a can of C4 energy drink.
