Ingredients

C4 Extreme Ingredients

C4 Extreme Ingredients

The C4 Extreme ingredients include:

  • Arginine alpha-ketoglutarate
  • Caffeine
  • CarnoSyn Beta-Alanine
  • Creatine nitrate
  • N-acetyl L-tyrosine
  • Huperzine A
  • Citrulline nitrate

Does C4 Extreme Work?

To see if this product could be effective, our team took a closer look at the ingredients found in the C4 Extreme formula:

Arginine alpha-ketoglutarate

Arginine alpha-ketoglutarate (AAKG) helps the liver process the common byproducts of intense training while boosting protein synthesis. This may help with recovery following a tough workout while preventing soreness at the gym.

However, one study published by the Journal of the International Society of Sports Nutrition found that consuming AAKG did not provide any benefits during training.

Caffeine

Caffeine is a mild stimulant found in many common items humans consume every day. One study in Sports Medicine determined that caffeine’s ergogenic effects are beneficial for exercise performance across a variety of workout types.

Furthermore, researchers from the Journal of the International Society of Sports Nutrition found that caffeine ingestion improved muscle strength and power during weightlifting sessions.

CarnoSyn Beta-Alanine

CarnoSyn Beta-Alanine was engineered to reduce the burning feeling when lifting. In a study published by Amino Acids, researchers found that participants who consumed beta-alanine during the four-week study saw increases in exercise capacity.

Creatine Nitrate

Creatine is considered one of the most commonly used supplements by weightlifters. The purpose of creatine is to help the body replenish energy stores fast so individuals can work out for longer and harder.

The Journal of the International Society of Sports Nutrition found that creatine can help increase strength, muscle morphology, and fat-free mass when partnered with heavy resistance training.

N-acetyl L-tyrosine

N-acetyl L-tyrosine is most used to improve focus, attention, and alertness and potentially improve overall mental performance in stressful situations. The Journal of the International Society of Sports Nutrition determined that those who consume N-acetyl L-tyrosine as a pre-workout supplement experienced a significant increase in reaction performance.

Huperzine A

According to C4 Extreme, the huperzine A in this formula comes from toothed clubmoss. Research published in the Journal of Functional Morphology and Kinesiology, this ingredient may prove to be beneficial to memory performance.

Weight Loss

C4 Extreme and Weight Loss

While C4 Extreme does not directly result in weight loss, the pre-workout energy and endurance gained from the formula may help improve training performance.

The caffeine and huperzine A may provide a boost of energy and focus during the workout. Finally, the beta-alanine improves exercise capacity which helps with endurance.

Side Effects

  • Anxiety

It is best to contact a medical professional before using C4 Extreme.

Bottom Line

Bottom Line on C4 Extreme Results

C4 Extreme meets its claims of improving muscular performance and fighting fatigue while boosting performance and supporting energy due to the ingredients in the formula. As a result, it has become one of the best-selling pre-workout supplements, but that doesn’t mean it’s effective. Although the product contains a number of healthy ingredients that may increase energy and exercise performance, most of them are not designed to aid in weight loss.

Additionally, it is important to remember that there are several side effects from high amounts of caffeine, so if you are susceptible to any of these issues, you may want to skip this product and opt for a stimulant-free pre-workout instead.
