Pre-workout supplements are becoming more and more popular. C4 or Cellucor is one of the options that so many people are interested in. C4 Pre-Workout is supposed to boost energy and it should be taken 20 to 30 minutes before having a workout.

While the concept of C4 does sound great, it’s also important to figure out whether the supplementation product is responsible for causing side effects. Here’s a brief overview about the way in which C4 impacts the body.

Some of the Common C4 Pre-Workout Side Effects

The Cellucor Pre-Workout formula is based on a range of ingredients. A few of the supplement’s most important components include caffeine, velvet bean extract, n-acetyl l-tyrosine, TeaCor tetramethyluric acid, arginine AKG and beta alanine.

People taking these supplements have experienced some side effects linked to one or more of the mentioned ingredients:

  • Allergic reactions: this is a common side effect that stems from an intolerance to some of the C4 ingredients. It’s very important to make sure that you’re not allergic to the natural compounds found in the product. A few of the C4 ingredients are common allergens. If you don’t know whether you’re allergic to any of the ingredients, start with a small quantity of the pre-workout supplement to test your tolerance.
  • Nausea: some people that have a sensitive stomach may experience a bit of irritation after taking C4. As a result, they’ll probably suffer from nausea and to a lesser degree – from vomiting.
  • Headaches: this is one of the most common C4 Pre-Workout side effects. Some of the ingredients like caffeine may stress out the body, which will contribute to the aches.

Less Common Side Effects

While the issues mentioned above are the most common side effects that people taking C4 Pre-Workout may experience, there are a few additional issues. These occur much less frequently but will still have to be mentioned:

  • Tunnel vision
  • Restlessness and shaking (due to the presence of caffeine in the formula)
  • Insomnia and other sleep issues, especially if C4 is taken in the evening
  • Heart palpitations
  • Nervousness
  • High blood pressure
  • Itchy skin

It’s a very good idea to undergo thorough medical assessment prior to getting started with a pre-workout supplement. Your doctor will let you know whether you suffer from a medical condition that makes the use of such a product risky. A physician will also help you assess the formulas of different products, thus identifying the best one for your needs.

People who suffer from high blood pressure, the ones that are sensitive to caffeine or any other ingredient and individuals that deal with kidney problems are advised to refrain from using C4.

The Bottom Line about Cellucor C4 Pre-Workout Supplement

C4 is a quality natural supplement and if you do a bit of online research, you’ll find dozens of positive customer reviews about it. Figuring out whether the pre-workout product is the right one for you, however, will necessitate some additional research.

Most people don’t experience problems as a result of using C4 to boost their energy prior to exercising. The product is an excellent stimulant that enhances fat burning, stabilizes the mood and delivers an energy boost. Still, just like every other supplement, Cellucor C4 isn’t intended for universal use by just about everyone.

Before giving Cellucor C4 a try, make sure that your body isn’t sensitive to caffeine. The manufacturer of the pre-workout supplement does a pretty good job in terms of providing ingredient and dosage information. Most people will be just fine when taking such a stimulant. A few, however, may experience an extreme sensitivity that makes the use of C4 a really bad idea.

Keep in mind that pre-workout supplements are considered dietary products. As such, they don’t fall under FDA regulations and they don’t go through a thorough scientific approval process. It’s up to you to figure out what each supplement contains and whether the specific blend of ingredients can jeopardize your health in any way.

C4 does work and it can make working out a whole lot easier (especially if you feel that your energy levels are low). Still, it contains about 325 milligrams of caffeine anhydrous per dose. For some people, the quantity is a lot. Test your individual tolerance and when in doubt – consult a physician.
