C4 Pre workout ingredients

CarnoSyn Beta-Alanine

Beta-Alanine is classified as a non-essential amino acid or protein-building block that aids in enhancing exercise performance[1]. Non-essential means our body is able to make it on its own even if we don’t get it from our food. However, some may want to increase their intake in hopes of achieving greater physical results.

Beta-alanine may enhance physical performance by boosting muscle carnosine that’s associated with enhanced muscle-building capacity. This, therefore, means that CarnoSyn Beta-Alanine aids in lowering the burning sensation that occurs during exercise. 

It’s not clear to what extent beta-alanine does this, however. The majority of the beta-alanine consumed is used for mental tasks such as increasing executive function. 

Creatine Nitrate

Creatine (NO3-T) is among the most well-documented sports supplement ingredients. Its effects have been backed by science for years. Creatine assists your body in replenishing lost energy during exercise[2]. Doing this may help increase your endurance and enable you to d go harder throughout your time in the gym.

Creatine Nitrate also draws water toward the muscles, thereby giving them a fuller, more defined appearance. . It also helps them function better. Creatine nitrate is an improved version of the often-used creatine monohydrate that’s supposedly more absorbable by the body. 

In any case, 1g of creatine is relatively low. It may give you that extra boost during workouts, but.  serious gym-goers often take it in relatively higher amounts. 

Arginine Alpha Ketoglutarate

Otherwise known as AAKG, Arginine Alpha-Ketoglutarate is said to help the liver in processing some of the byproducts of exercise and increasing protein synthesis. Arginine Alpha-Ketoglutarate helps with recovery post-workout[3] and keeps you from feeling sore and stiff while exercising. 

However, a dose of 1g in the C4 Original Pre Workout is not high and not something that may have a huge impact on your workout sessions. But, it may give you a short-term energy boost.

Caffeine Anhydrous

Caffeine is a mild stimulant that’s prevalent in most energy drinks, sodas, tea, and coffee. The 150mg dose in C4 Original Pre-Workout blend is a notch higher in comparison to a regular cup of coffee. 

With regards to performance, studies[4] suggest that caffeine is beneficial for both physical and cognitive performance. The majority of the caffeine benefits are visible in regards to aerobic endurance more than other types of exercise. 

It’s important to keep in mind that everyone has their own tolerance to caffeine. If you’re particularly caffeine sensitive, this amount of caffeine may be too much for you.

N-Acetyl-L-Tyrosine

Tyrosine is a naturally-produced amino acid within the body that’s used in making essential compounds such as melanin, hormones, adrenaline, and dopamine. Research[5] shows that tyrosine may be beneficial in boosting mental performance during stressful situations. 

Velvet Bean Seed Extract

Velvet Bean Seed Extract is an essential ingredient packed with plenty of benefits. It contains antioxidant, neuroprotective, anti-inflammatory, and anti-diabetic properties[6]. Velvet Bean Seed Extract also induces positive cognitive and mood-boosting capabilities. 

Theacrine

Theacrine, otherwise known as Teacrine, is a natural compound that supposedly boosts your motivation and mood[7]. It doesn’t contain stimulant effects when compared to caffeine. Theacrine makes you happier, more motivated, more alert, and generally improves your mood. It does all these without inducing effects from other stimulants. The exact amount of Theacrine is not listed on the ingredient label or official website, as it is part of a proprietary blend of ingredients.

Cellucor C4 Pre-Workout also contains additional ingredients such as B Vitamins that play a critical role in ATP (Adenosine Triphosphate) production. ATP is important for providing energy for different metabolic processes[8].

“C4 is okay, nothing special in my opinion. It gives me a little bit of energy but nothing like some of the other pre-workouts I’ve tried. It’s also really expensive so I probably won’t be buying it again.”

“I’ve been using C4 pre workout for about a month now and I’m really liking it. I’m not usually one to take supplements but this stuff has definitely helped me get through my workouts.

Health Benefits of C4 Pre Workout

C4 pre-workout can offer several health benefits. The caffeine in C4 can help to improve focus and mental alertness. If you’re someone who struggles to get going in the morning or feels like they need an extra boost of energy before their workout, then C4 could be a great option for you. 

The beta-alanine in C4 delays fatigue during exercise, meaning you can work out for longer without feeling as tired. Arginine is an amino acid that has been shown to improve blood flow and increase muscle pumps. Creatine is a popular supplement that helps to add size and strength. Lastly, it contains B-vitamins which are essential for energy. 

Potential Side Effects

There are no reported side effects from taking C4, but as with any supplement, it’s always best to start with the lowest possible dose to assess your tolerance. C4 If you experience any jitteriness, anxiety, or heart palpitations then you should immediately discontinue usage.

Before you start taking Cellucor C4 Original Pre Workout, we suggest that you consult with a qualified and licensed health care professional to discuss the pros and cons. This should be the case especially if you’re on alternative dietary supplements, over-the-counter medications, or prescription drugs.

Dosage

C4 pre-workout is available in powder form. The minimum effective dose is one scoop (about 11 grams) mixed with water (6 fl. oz.). You should ideally consume it approximately 20-30 minutes before your workout. C4 can be taken on an empty stomach or with a light meal.

Final Thought

Probably the best part about C4 is its awesome taste. The artificial flavors are blended perfectly together to produce varieties such as Watermelon, Orange Burst, Cherry Limeade, Strawberry Margarita, Icy Blue Razz, and so on. The smell of the supplement is just as attractive as its taste. 

Overall, we believe that C4 is one of the best pre-workout supplements, and is a great product for anyone looking for a little extra energy and focus. The ingredients are clinically proven to be effective, and many people anecdotally report feeling more energized after taking this supplement.

There are no known side effects, but it’s important to recognize that everyone responds to products differently. Always consult with your medical provider before starting any new supplement. 

If you determine it is safe for you, It should be taken as prescribed to avoid any serious adverse reaction. If you experience insomnia or jitters while using C4, discontinue use immediately. If you’re looking for something to help you push through your workouts, then the C4 pre-workout is definitely worth trying.
