NutraBio Fighter Fuel v3 – A Combat Athlete’s Pre Workout

NutraBio Fighter Fuel V3

Fighter Fuel V3 from NutraBio is the next evolution in crafting the ideal formula to get you ready to hit the Octagon!

Last we heard from NutraBio, they just released a brand new meal replacement powder, aptly title Muscle Matrix MRP, that utilized a perfect balance of proteins, carbs, and fats to give you a healthy on the go option to refuel after a grueling workout.

They’re not done either. The company also recently released an upgrade to their pre workout intended for the combat athlete or weekend MMA-Warrior. Fighter Fuel V3 is the next step in crafting the ideal formula to get you ready to hit the Octagon!

We’re already huge fans of their main pre workout supplement, NutraBio Pre Extreme, which is quite high on our list of best pre workout supplements. Where will this one fit in, and who’s it for?

Fighter Fuel Quick Notes

  • Loaded ingredient panel
  • But only 100mg caffeine for fighters and crossfitters
  • Several endurance ingredients
  • 18g carbohydrates from Cluster Dextrin
  • Men’s and Women’s versions available (we discuss men’s here)

Our take? Fighter Fuel is what all of those “energy amino” products wished they could be.

Fighter Fuel V3 Ingredients

As with all NutraBio products, you get a crystal-clear ingredients panel that lays everything out for you in plain English — and they even disclose the colors and flavors added!

This is an endurance-heavy pre workout. Lots of leucine, beta alanine, citrulline malate, taurine, N-Acetyl-L-Tyrosine… but not too much caffeine (100mg) because quite frankly, fighters and CrossFitters really don’t need the heart rate to get any higher!!

The most notable differences between V2 and V3 is the increased amount of Cluster Dextrin and Betaine over the previous iteration – more carbs (but not so many that you get sick) is great for endurance too.

Enough preamble though, let’s get to the men’s formula – women, remember that yours will have slightly lower dosing!

  • Glycogen & ATP Preload System

    • Highly Branched Cyclic Dextrin (19g)

      NutraBio Fighter Fuel Ingredients

      Notable upgrades to V3 include 4 more grams of Cluster Dextrin and a full clinical dose of betaine! Note that there is a separate women’s formula with a bit less inside (and for less money).

      Right off the bat is the first big change from V2 to V3. The latest incarnation of Fighter fuel contains four more grams of Highly Branched Cyclic Dextrin (HBCD). Carbs fuel performance, and if you’re headed for a lengthy sparring session, the last thing you want is an empty tank.

      HBCD is a special type type of sugar derived from amylopectin that has a higher molecular weight and lower osmolality. Basically this means that HBCD doesn’t sit in your stomach as long as maltodextrin or waxy maize[1], which could leave you slow and heavy. Instead, HBCD is rapidly digested and immediately transported to your muscles where it can power all the punches and kicks you’re about to throw.

    • PharmaPure™ Creatine Monohydrate (2g)

      There’s not much to creatine monohydrate that needs to be explained. It’s a staple for any athlete, bodybuilder, or fighter that wants to:

      • Boost power and strength[2,3]
      • Increase Lean Mass Gains[4,5]
      • Decrease fatigue[6]
      • Reduce soreness and muscle damage[7,8]
    • You’ll get most of your daily dose from monohydrate, but we’ve got more to come in our next ingredient.

    • Creatine HCl (1g)

      Creatine Solubility

      Creatine HCl has greater solubility than monohydrate which leads some to believe it doesn’t give the “bloat” that monohydrate does.

      Here’s the rest of our daily 3-5g of Creatine needs, the ever-trendy Creatine Hydrochloride. Creatine HCl’s calling card is increased bioavailability and absorption compared to creatine monohydrate.

      Based on this fact, many users claim they don’t experience the “bloat” and puffiness that they usually get with monohydrate, which is usually blown way out of proportion any way.

      Regardless, we’re now at a total of 3g of creatine between the two forms and that should easily cover most individuals needs out there.

    • L-Alanine (600mg)

      Another big improvement over Fighter Fuel V2 is double the amount of the amino acid L-Alanine. Once ingested and taken up by the liver, L-Alanine is converted to pyruvate. This compound is critical for the production of glucose and blood sugar management.[9]

      The last thing you want during a match is to “bonk” by running low on blood sugar. Alanine helps sustain glucose levels and makes sure there’s no mid round crash, unless you get knocked out of course!

  • Nitric Oxide, Endurance, & Performance Matrix

    Now it’s time for some pumps, but mostly the endurance aspect instead.

    • Citrulline Malate 2:1 (6g)

      NutraBio 90 Day Challenge

      Don’t forget to follow along with NutraBio’s 90 Day Challenge where you could win a BOATLOAD of supplements!

      The older version of Fighter Fuel has 5g separately of L-Citrulline and Citrulline Malate. V3 does away with the duo and gives us 6g of 2:1 Citrulline Malate.

      While this will indeed give you a great pump due to the increased Nitric Oxide production citrulline malate confers, that’s not really what you’re interested in here. Citrulline Malate is also great for increasing ATP production and endurance.[10,11,12,13]

      Citrulline Malate accomplishes this by acting as a buffer in the body helping to remove excess levels of lactic acid and ammonia which can hinder performance and induce premature fatigue.

    • CarnoSyn® Beta Alanine (2.5g)

      Beta alanine is one of the few truly proven commodities in the supplement industry.  BA binds to histidine in skeletal muscle to form carnosine, a potent lactic acid buffer. This helps increase power output and reduces muscle fatigue.[14,15]

      Fighter Fuel contains 2.5g, which is below the typically recommended dosage of 3.2g. To make sure you’re getting your daily fill of BA, you may want to add some bulk to this to get the clinically studied dose of 3.2g

    • L-Aspartic Acid (600mg)

      L-Aspartic Acid is a non-essential amino acid derived from plants that plays a key role in energy production. It’s one of the many components required to transport NADH molecules from the main body of a cell to its mitochondria, the main energy driver of cells.[16]

      NADH is then used to generate ATP, which is the molecule that powers all activity inside a cell. Adding L-Aspartic Acid to Fighter Fuel V3 can help increase your endurance by reducing the amount of fatigue you may feel during your workout.

  • Strength, Power, & Recovery Complex

    • L-Leucine (3.5g)

      Pick the winner of the Big Game and win the ultimate workout stack from NutraBio!

      Here’s a major upgrade over V2, an extra 1.5g of Leucine!

      Leucine is the most studied, and well-known, of the 3 Branched Chain Amino Acids (BCAAs). Leucine activates the mTOR pathway in the body which stimulates muscle protein synthesis.[17]

      It’s by far the most anabolic of the BCAAs and while help spur muscle growth as well as stave off catabolism.[18]

    • Betaine Anhydrous (2.5g)

      Here’s another huge upgrade over Fighter Fuel V2… three times as much betaine! Also known as trimethylglycine, betaine has become a must have ingredient in most pre and post workout products on the market. Including it in Fighter Fuel V3 helps boost endurance, power, and muscle protein synthesis during and after your workout, when it’s critical![19,20,21]

    • L-Ornithine AKG (500mg)

      Ornithine Alpha-Ketoglutarate (OKG) is a salt formed from the combination of ornithine and alpha-ketoglutarate (AKG), in a 2:1 ratio. OKG is another nitric oxide boosting ingredient in Fighter Fuel V3 that helps promote greater blood flow and oxygen delivery to muscles.[22] This leads to improved performance and greater endurance during intense workouts or sparring sessions.

  • Electrolyte Optimizer

    • Taurine (1.5g)

      NutraBio Kick

      Fighter Fuel V3 gives you everything you need to kick the competition in the face!

      Taurine is a non-essential amino acid that greatly enhances hydration. It serves as a cell volumizer helping to pull extra water and nutrients into the muscle belly.[23]

      Taurine helps increase endurance, thanks to extra hydration, as well as reduce symptoms of DOMS.[24]

    • TRAACS® Calci K (525mg)

      Calci K is a trademarked blend of calcium and potassium patented by Albion Human Nutrition.[25] Calcium and Potassium work hand in hand to ensure your body maintains its high level of performance throughout your entire workout.

      Most know calcium as the all-too-important mineral required for building and maintaining healthy bones. More importantly, calcium supports muscular contractions of the heart and skeletal muscles, both of which need to be operating at peak levels during a fight!

      Potassium helps sustain you through the fight, as decreased levels of it can result in cramping, fatigue, and delayed reflexes.[26]

    • Sodium Phosphate (50mg)

      It’s inevitable that you’re going to sweat when in the heat of battle. Your heart’s pumping and adrenaline is cranking. Loads of electrolytes, like sodium, are lost through sweat, and losing even a fraction of your electrolyte and hydration levels can lead in altered CNS function and decreased performance.[27]

      For this reason alone, it’s vital to maintain adequate electrolyte levels during battle.

  • Focus, Drive, & CNS Stimulator

    Now here’s where NutraBio got smart. The demographic for this product does not want a ton of caffeine. They’ll take the focus though! So you get the best of both worlds here:

    • N-Acetyl L-Tyrosine (1.5g)

      NutraBio Supercharge

      Turbocharge your workout and sparring sessions with the newest version of Fighter Fuel.

      N-Acetyl-L-Tyrosine (NALT) is the acetylated form of the amino acid L-Tyrosine. NALT is a more bioavailable (and more expensive) form of L-Tyrosine that increases production of noradrenaline and dopamine in the body. These two neurotransmitters in the body are big time players in the body that help increase focus and mood in addition to lowering stress and anxiety.[28,29].

      This is a HUGE Dose! Usually, we’re thrilled to get 1.5g of L-Tyrosine, getting 1.5g of NALT should result in some HEAVY focus during your matches!

    • Caffeine Anhydrous (100mg)

      Chances are if you’re practicing martial arts or heading into a sparring bout, you’re already pretty amped up. The last thing you need is a mega dose of caffeine to further jack your heart rate up and send you out of control.

      For this precise reason, Fighter Fuel V3 contains a moderate amount of caffeine that will give you a mild boost in energy, mood, and focus that can carry you through the duration of the match.

    • Huperzine A (100mcg)

      The last of our cognitive boosters in Fighter Fuel V3 is Huperzine A. This compound inhibits acetylcholinesterase, the enzyme responsible for degrading acetylcholine[30], a.k.a. the “learning neurotransmitter.” The end result is more acetylcholine circulating through the body leading to heightened focus and a more “locked in” feeling.

      Lastly, huperzine can act as a neuroprotectant, helping prevent cognitive decline as well as foster the creation of new brain cells.[31]

  • Nutrient Absorption Enhancer

    • Bioperine® (5mg)

      NutraBio Fighter Fuel Flavors

      Fighter Fuel V3 comes in Green Apple and Raspberry Lemonade to power you through your intense workouts.

      Bioperine® is the patented black pepper extract derived from piperine. It’s used across the industry to enhance the absorption of other ingredients in dietary supplements by inhibiting certain enzymes in the body that would otherwise prematurely break them down.[32]

Flavors Available

Fighter Fuel V3 comes in 20 serving tubs in either Green Apple or Raspberry Lemonade.


Well that was exhaustingly impressive. Not that we’re surprised given the products NutraBio’s put out lately!!

Whether you’re training to head into the ring or just a weekly martial arts practitioner, you need a different kind of pre workout than your typical bodybuilder meathead. Fighter Fuel V3 gives you everything you need to prepare your body for a tough sparring session and then some.

Not too much stims, but just enough to keep you energized with a healthy hit of carbs to carry you through the final round. Before your next bout, take a serving of this and experience vastly improved fighting performance.

Sign us up. This one looks perfect for the right audience. Are you a Fighter?
