The Science Behind NutraBio Men's Fighter Fuel
A closer look at the 16 ingredients and dosages used to make NutraBio Men's Fighter Fuel the premier low stim pre-workout on the market.
Cyclic Dextrin is a clinically studied carbohydrate that is rapidly absorbed and provides fuel (glycogen) to working muscles.
Cluster Dextrin is highly soluble and promotes fast gastric emptying times; virtually eliminating any gastric distress associated with less advanced carbohydrates.
Cluster Dextrin maintains a slow release, offering the ideal interaction between carbohydrate breakdown and the natural release of free fatty acids. The result: superior carbohydrate absorption and superior endurance.
In a 2013 human clinical trial of Cluster Dextrin, 24 adult male athletes showed that during cycling exercise, the group administered 15 grams of Cluster Dextrin performed better than those who took the same amount of a maltodextrin.
Unlike other formulations using Cluster Dextrin that have dextrose or maltodextrin hidden in the "other ingredients," NutraBio uses only pure Cluster Dextrin.
PharmaPure™ Creatine Monohydrate
Creatine is a compound produced in the body that serves as the primary fuel source (ATP) for short duration, high-intensity activities such as sprinting and weight lifting. Creatine is stored primarily in muscle tissue and is used for rephosphorylating ADP into ATP. This means that when our muscles use up our energy stores, creatine helps to replenish those stores in a relatively rapid manner. Approximately 2 grams of creatine are found in individuals that do not supplement and maintain a diet including animal based proteins. Those who do supplement can increase their body's internal creatine pool by 10 to 40% depending on diet and total lean muscle mass.
As a whole creatine is arguably the most extensively researched and effective supplement available today. Over 500 studies exist on the ergogenic benefits of creatine supplementation with over 70% of these studies producing significant improvements in performance without any detrimental side effects.
Creatine has been proven to increase lean muscle mass, maximal strength, power, and muscular endurance.
Creatine may also help keep you hydrated in extreme outdoor conditions.
Emerging research suggests creatine may provide cognitive and overall brain health benefits.
The ISSN (International Society of Sports Nutrition) position stand on creatine monohydrate (CM) found that short-term CM supplementation has been reported to improve maximal power/strength (5–15%), work performed during sets of maximal effort muscle contractions (5–15%), single-effort sprint performance (1–5%), and work performed during repetitive sprint performance (5–15%). Long-term CM supplementation appears to enhance the overall quality of training, leading to 5 to 15% greater gains in strength and performance.
L-Alanine is a free-form non-essential amino acid. The liver can convert L-Alanine into glucose which can be used as an energy source during exercise.
L-Alanine is an excellent addition to your pre-workout energy drink because it serves as muscular fuel for increasing power, strength and endurance for performance athletes.
L-Alanine can also function as an inhibitory or calming neurotransmitter in the brain.
Power, Strength & Endurance Complex
L-Citrulline (fermented)(Kyowa Quality)
L-Citrulline is an amino acid that plays a significant role in nitric oxide metabolism and regulation.
It is converted to L-Arginine in the body to support L-Arginine and nitric oxide levels.
Increased production of nitric oxide (NO) promotes vascular dilation which improves oxygen and blood circulation throughout the body.
L-Citrulline is also expected to relieve muscle fatigue through ammonia elimination.
A 2015 study conducted by Bailey et al. found subjects who supplemented with 6000mg L-Citrulline for seven days were able to improve oxygen uptake and performance during high-intensity exercise.
L-Leucine (fermented natural)
Leucine is one of the branched-chain amino acids (BCAA). By itself it can stimulate muscle protein synthesis; the process responsible for muscle growth and recovery. This is why it is often referred to as the "main" amino acid.
Supplementation with at least 2/grams daily has been shown to decrease muscle soreness, lessen recovery time between workouts, and increase lean muscle mass.
Howatson et al. (2012) discovered that leucine (combined with isoleucine and valine) administered before muscle damaging resistance exercises reduced indices of muscle damage and accelerated recovery in resistance-trained males.
NutraBio's leucine is derived from fermented vegetable sources as opposed to animal-based sources.
Beta-alanine (BA) is a version of the amino acid alanine which serves as the precursor to carnosine (β-alanyl-L-histidine) in skeletal muscle. Supplementing with BA is a highly effective means of increasing muscle carnosine content. Increased muscle carnosine helps buffer the adverse side effects of hydrogen ion accumulation in muscles as exercise intensity increases.
Beta-Alanine supplementation has been linked to improved exercise performance and delayed fatigue at higher intensities in both trained and untrained individuals in events lasting 1-4 minutes.
Increases in lean muscle mass and muscular endurance have also been noted with supplementation.
A recent meta-analysis confirmed the ergogenic effects of beta-alanine, showing a 2.85% increase in exercise performance compared to placebo when dosed at ~2/grams daily.
Betaine, scientifically referred to as Trimethylglycine, is a metabolite of choline. Betaine's two main functions in the body are as a methyl donor and osmolyte. As an osmolyte, betaine protects proteins, cells, and enzymes from heat, dehydration, and other physiological stresses. As a methyl donor, betaine is used to convert homocysteine to L-methionine, and is, therefore, a precursor to creatine.
Doses of 2500-6000mg betaine daily may increase muscular strength, endurance, and total training volume.
Betaine also plays a role in hepatic fat metabolism, promoting muscle protein synthesis, and has been suggested to increase nitric oxide levels.
A study conducted by the University of Connecticut found that individuals supplementing with 1.25 grams of betaine twice/daily increased bench press power by 20%.
L-Aspartic Acid is a non-essential amino acid that plays a vital role in energy production.
It is one of the components necessary to move high-energy NADH (nicotinamide adenine dinucleotide) molecules from the main body of a cell to its mitochondria, or primary energy-production areas.
Once there, the NADH is used to generate ATP, the energy that powers all cellular activity.
Supplementing with L-Aspartic Acid increases resistance to fatigue and allows athletes and bodybuilders to sustain longer workouts with greater performance, less fatigue, increased stamina and increased endurance.
Low levels of aspartic acid can cause chronic fatigue because it can lead to lowered cellular energy.
Taurine is one of the most important, useful, and safest amino acids. Taurine is best known for its beneficial effects on the heart and cardiovascular system. Early clinical research also suggests that taurine, in combination with caffeine, can produce improvements in mental performance. When the body engages in extreme physical activity, it no longer will be able to produce the necessary amounts of taurine. Therefore supplementation becomes necessary.
Taurine is involved in the regulation of core body temperature and may help prevent heat stress and stroke.
Taurine also acts as an osmolyte; assisting the body in maintaining proper water balance.
Zhang et al. (2004) found that individuals who supplemented with taurine for one week before an exhaustive exercise bout significantly improved time to exhaustion, VO2 max, and maximal workload. It also decreased exercise-induced DNA damage.
Calcium, potassium, and phosphorus are vital electrolytes needed to maintain water balance and facilitate motor neuron function.
The combination of these electrolytes in CALCI-K are highly soluble and readily absorbed by the body.
Electrolytes have been shown to prevent muscle cramps and are essential to normal muscular contractions.
As we exercise, electrolytes are lost through sweat and must be replaced to prevent decreases in performance.
Sims et al. (2007) discovered that pre-exercise ingestion of a high-sodium beverage increased plasma volume before exercise and involved less thermoregulatory and perceived strain during exercise and increased exercise capacity in warm conditions.
Focus & Drive Stimulator
Tyrosine is an essential amino acid whose primary role in the body is as the direct precursor to Thyroxine and the hormones dopamine, epinephrine, and norepinephrine.
Tyrosine may improve both endurance and anaerobic performance via metabolic and neurotransmitter upregulation.
Tyrosine also improves mental acuity, focus, and mood by increasing levels of catecholamines found in the bloodstream.
A study done at the Naval Aerospace Medical Research Laboratory reported that a dose of L-Tyrosine, when provided to sleep-deprived subjects, ameliorated psychomotor performance declines associated with mental fatigue.
Caffeine, like creatine, it one of the most studied and proven ergogenic (performance enhancing) aids. Although caffeine can affect a wide variety of motor and mental functions, it is most commonly used to improve endurance exercise, focus, cognitive performance, and improve energy levels. Caffeine has also been shown to have a thermogenic effect (heating/calorie burning) at rest and may increase the use of fats for fuel during exercise.
The ISSN position stand on caffeine concluded:
Caffeine can act to enhance alertness and vigilance during times of exhaustive exercise that requires sustained focus.
Caffeine is an effective ergogenic aid for sustained maximal endurance activity and has also been shown to be very useful for enhancing time trial performance.
Caffeine can improve, not inhibit, glycogen resynthesis during the recovery phase of exercise.
Caffeine is beneficial for high-intensity exercise of prolonged duration.
Huperzine-A is a selective inhibitor of the neurotransmitter acetylcholinesterase (AChE), which means it prevents the breakdown and increases the amount of acetylcholine; an important neurotransmitter in the central nervous system involved in cognition and muscular contractions.
Multiple studies have shown that supplementation with Huperzine-A can enhance focus, memory, and mood.
A study conducted by Sun et al. (1999) reported that subjects who supplemented with Huperzine-A for four weeks improved learning performance and memory compared to a placebo group.
Men's Fighter Fuel FAQs
What is the best way to take Men's Fighter Fuel?
As a dietary supplement, mix one scoop of Fighter Fuel into 8-12 ounces of cold water and consume 30 minutes before exercise. Vary the amount of water to achieve your desired flavor. Fighter Fuel is incredibly powerful; first-time users should begin use with 1/2 scoop or less to assess tolerance. DO NOT EXCEED 1 SCOOP IN ANY 24 HOUR PERIOD. For optimal results, drink a minimum of 1 gallon of water daily.
Why are there carbs in Men's Fighter Fuel?
One of the most serious downfalls of pre-workout supplements is the absence of complex carbohydrates that are needed to fuel intense workouts and prevent muscle catabolism (the breakdown of muscle tissue for use as fuel). The primary source of muscle energy is ATP (adenosine triphosphate) which comes from glycogen stores in the liver and muscle tissue. During exercise, glycogen is broken down into glucose molecules which are converted to ATP to fuel muscle contraction. Amino acids from lean muscle tissue are mobilized to slow the depletion of glycogen and make up any glycogen shortfall during intense exercise. Fighter Fuel's carbohydrate formula contains complex carbohydrates which are used to top off glycogen stores to help prevent muscle tissue breakdown during training and give you consistent and sustainable energy.
Can I take Fighter Fuel with other stimulants (i.e. coffee, fat burners)?
We don't recommend taking other stimulants with Fighter Fuel.
I heard creatine can cause kidney problems and cause cramping. Is that true?
Absolutely not. Creatine is the most studied and effective supplement ever…period. Over 500 studies have been done on creatine, and none have shown to cause any adverse side effects. However, you should expect to see big improvements in strength, power, and endurance after taking creatine.
What makes Fighter Fuel better than other low stim pre-workouts?
A lot of other low stim pre-workouts use ingredients that are ineffective or not properly dosed. All the ingredient in Fighter Fuel are research backed and dosed efficaciously based on the current scientific literature.

Just received this product yesterday. I have experimented with many pre-workout supplements. After seeing this new revised formula in Green Apple I figured I would give it a try. I definitely do not regret it. By far the best pre workout formula I have experienced yet, both in terms of feel and flavor. Low stimulant, but great natural energy overall. I would definitely recommend this to everyone. My hope is that they can increase the quantity servings to get a little extra bang for the buck. At 20 servings it will get expensive to continuously use it daily.
