NutraBio PRE was formulated with a single goal in mind: to create the absolutely most effective, thorough, and purest pre-workout in existence…period. We can say without a doubt that this goal has been accomplished, making PRE one of the most powerful pre-workouts on the market today.*

PRE is built upon clinically dosed and scientifically backed ingredients that have been suggested to maximize workout performance and produce results.* Athletes of all levels realize that in order to achieve the most effective training session, energy, strength, endurance, and focus are musts. A complete pre-workout supple- ment should support all of these benefits.* the

The synergistic combination of ingredients found in PRE will help prepare your body physiologically and psychologically by amplifying energy, enhancing the mind-muscle connection, and supporting increases in muscular strength, power, and endurance.* From top to bottom, PRE will help keep you training, stronger and longer.

Founded in 1996, NutraBio is the original No Proprietary Blend, No B.S. honest brand. 15 years ago we revolutionized the supplement industry by introducing 4 quality commitments:

1. NO proprietary blends and full label disclosure

2. NO fillers, excipients, or additives (except flavor)

3. Full efficacious dosages of every active ingredient*

4. Manufacturing our own products to control every aspect of quality.

Two decades ago we set the goal of providing our customers with the most effective, clean and honest supplements available. Since that very first day, we have led the charge in supplement innovation with science-backed efficacious doses and full label disclosure.

We manufacture our products in our FDA registered and audited facility. We are GMP certified and manufacture to exceed 21 CFP Part 111 cGMP regulations. We don't compromise on quality so you don't have to compromise on results.

Loaded with 27G of 22 active ingredients

  • Clinical doses of 22 research-backed ingredients.
  • Caffeine Anhydrous and Infinergy Di-Caffeine Malate to boost energy, enhance focus, and provide greater training intensity. All without a caffeine crash.*
  • CarnoSyn Beta-Alanine (3.2g) - Increase endurance and help counteract fatigue caused by the accumulation of hydrogen ions.*
  • PharmaPure Creatine Monohydrate (3g) - Greater strength, power, and muscle growth. Creatine MagnaPower for increased solubility and absorption*
  • L-Leucine (3.5g) - Help prevent muscle catabolism and lessen recovery time between sessions.*
  • Theapure L-Theanine (300mg) - When combined with caffeine, it promotes enhanced cognition and attention*
  • Huperzine (100 mcg) - Promote a strong mind-muscle connection and supercharge mental focus.*
  • Betaine Anhydrous (2.5g) - Support creatine production, increase power and strength output, and protect cells from dehydration.*
  • Agmatine Sulfate (1g) and Nitrosigine (750 mg) - Stimulate nitric oxide pathways, leading to greater vasodilation and bigger muscle pumps.*
  • Electrolyte and Hydration Optimizer (2214 mg) - Help maintain water balance in the muscle, facilitates motor neuron function, and supports exercise capacity.*


Since day one, 20 years ago, NutraBio has never been happy just maintaining the status quo when it comes to pre-workouts. Although the industry makes it seem like non-proprietary blends, proper dosing, and scientifically backed ingredients are something new, the fact is that NutraBio pioneered this trend over 15 years ago. We focused on creating the best, and we've done just that with our latest version of PRE. PRE has everything you need in one comprehensive, open-label, clinically dosed formula and nothing you don't. We pride ourselves on purity. What you see on the label is exactly what you get. PRE contains no fillers, excipients, proprietary blends, or other potentially unhealthy or unneeded additives.

At the end of the day, NutraBio isn't just about marketing hype and trying to maximize our profit. It's all about giving athletes what they want to meet their performance needs by giving them access to clean supplements that are innovative and effective. Like you, we want to train hard and see the results of our efforts. Compare NutraBio PRE to any other pre-workout on the market, and ask yourself which formula was created WITHOUT COMPROMISE. We think that you'll find that even the most "self-proclaimed" strongest formulated pre-workouts pale in comparison to PRE.

The Science Behind NutraBio PRE

A closer look at the 22 ingredients and doses used to make NutraBio PRE the premier pre-workout on the market.

L-LEUCINE (3.5g)

  • Leucine is one of the essential 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 leucine has been shown 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 vegetables 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 negative 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 one to four minutes.*
  • Increases in lean muscle mass and muscular endurance have also been noted with supplementation.*
  • A recent meta-analysis confirmed the ergogenic effect of beta-alanine, showing a 2.85% increase in exercise performance compared to a placebo when dosed at ~2 grams daily.*


  • Creatine is an amino acid (broken down protein) derived 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 it 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 fairly rapid manner. Approximately 2 grams of creatine are found in individuals that do not supplement and maintain a diet including animal based proteins.*
  • As a whole creatine is arguably the most extensively researched and effective supplement available today. Over 500 studies exist of 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.*
  • Creatine MagnaPower is more soluble than creatine monohydrate and in theory should absorb better; requiring a lower dose to achieve the same ergogenic benefits as creatine monohydrate.*
  • 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.*


  • 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 an 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.*


  • Malic acid plays a vital role in the Krebs cycle where it helps turn carbs, proteins, and fats into energy.
  • If there is an inadequate supply of malic acid in the body the Krebs cycle cannot function properly which leads to premature fatigue.*

L-CITRULLINE (fermented)(Kyowa Quality)(6g)

  • L-Citrulline is an amino acid that plays an important 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 7 days were able to improve oxygen uptake and performance during high-intensity exercise.*


  • Agmatine Sulfate is a byproduct of Arginine through decarboxylation. It produces other byproducts that are involved in cell growth, structural and metabolic support to the nervous system.*
  • PRE uses a vegan source of agmatine that us derived from fermented plants.


  • Nitrosigine is a bonded complex of arginine and silicon that helps enhance nitric oxide levels to a greater degree compared to arginine alone.*
  • Increased nitric oxide levels promote the relaxation of smooth muscle in blood vessels, increasing blood flow to working muscles.*
  • In pre-clinical studies nitrosigine was found to be more biologically active than arginine chloride. The research also showed enhanced blood flow during and after exercise which may help with muscle growth and recovery.*


  • Tyrosine is an essential amino acid whose primary role in the body is as the direct precursor to thyroxine and to the hormones dopamine, epinephrine, and norepinephrine.*
  • Tyrosine may improve both endurance and anaerobic performance via metabolic and/or neurotransmitter upregulation.*
  • Tyrosine also improves mental acuity, focus, and mood by increasing levels of catecholamines found in the bloodstream.*

CHOLINE BITARTRATE (VitaCholine®) (500mg)

  • Choline Bitartrate is formed when choline is combined with tartaric acid.
  • This increases the choline's bioavailability and in turn, makes it more effective.*
  • When supplemented, choline bitartrate increases levels of acetylcholine in the body....a neurotransmitter that stimulates muscle contractions and is required for proper memory, cognition, and motor control.*
  • Increasing choline levels can produce a nootropic type effect as well as create longer and stronger muscle contractions.*


  • Caffeine, like creatine, is one of the most studied and proven ergogenic (performanceenhancing) aids. Although caffeine can affect a wide variety of motor and mental functions, it is most commonly used to improve endurance exercise, focus, and 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.*
  • Dicaffeine Malate, as the name implies, is the combination of caffeine and malic acid. Adding malic acid to caffeine is thought to calm the digestive effects of caffeine and thought to replenish the energy produced by caffeine (either through increased fat oxidation or ATP production). Malic acid may also weaken the feeling of a caffeine crash and slow tolerance development to caffeine.*
  • According to the research, higher doses of caffeine, in the 250-450mg range, are needed to provide an ergogenic benefit.*
  • The ISSN position on caffeine concluded that: • 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 effective for enhancing time trial performance. • Caffeine can enhance, not inhibit, glycogen resynthesis during the recovery phase of exercise. • Caffeine is beneficial for high-intensity exercise of prolonged duration.*


  • Research suggests that L-theanine's biggest supplemental role may be in taking the "edge" off of other stimulants.*
  • A combination of L-theanine with caffeine is noted to be synergistic in promoting cognition and attention.*
  • Giesbrecht et al. found that the combination of L-theanine and caffeine significantly improved accuracy during task switching, self-reported alertness, and reduced self-reported tiredness.*

HUPERZINE A (100mcg)

  • Huperizine A is a selective inhibitor of the neurotransmitter acetylcholinesterase (AChE), which means that it prevents the breakdown of and increases the amount of acetylcholine, an import ant 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.*


  • 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 also acts is an osmolyte; assisting the body in maintaining proper water balance.*
  • Zhang et al. (2004) found that individuals who supplemented with taurine for 1 week before an exhaustive exercise bout significantly improved time to exhaustion, VO2 max, and maximal workload.*


  • Calcium, potassium, and phosphorus are vital electrolytes needed to maintain bodily 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 in order 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.*

this is for the NATURALS PRE. PRE is dosed with ingredients that are scientifically proven to be effective. another super nice touch is that the formulations are totally transparent and fully disclosed. theres not a hint of any kind of prop blend that can hide all kinds of undesirable things and fillers. the Green Apple flavoring of PRE is outstanding, whoever was responsible for putting this flavor together should get a huge raise! just the right mix of sweet and sour the product mixed up very well. i loved the way that PRE performed....18 effective ingredients ( including L-Citrulline, Carnosyn Beta Alanine, L-Leucine and 350 mg of natural Caffeine to name a few) combine to make for a memorable training experience. great energy, focus, endurance and pumps let you breeze through your most strenuous workouts

Amazing formula from the 1st company in the industry to completely disclose every ingredient (including sucralose, flavoring, natural coloring, etc). I especially appreciate that it comes in a stim-free & unflavored option incase you're stacking it w/other flavored products such as bcaas, creatine, carbs, etc. The focus is exceptionally clean w/out any jitters and the energy lasts for 3-4hrs during high reps/sets or max out sessions. The Blue Raspberry flavor has an additional 500mg of DL Malic Acid delaying fatigue even further & the pump/endurance are truly reliable as everything is well-dosed in the upgraded re-formulation. The Green Apple is my favorite flavor which is nice and light but satisfying; rasperry lemonade & tropical fruit punch are similar & don't taste overly sour or tart. I strongly recommend Nutrabio's Pre to everyone of all weightlifting & sport endeavors as one's power output will be greatly enhanced; adding nitrates and glycerol is also a nice enhancement but not necessary. Thanks for setting the standard Nutrabio!

This review is for the Natural Series Pre in Green apple. I recently tried this for a week and really liked it. I don't have much of a tolerance to caffeine so I stuck with 1/2 scoop and that was perfect for me. Very different feel than some other pre's I've tried in that I didn't feel all amped up when not under a bar; but as soon as I grabbed a bar, all the energy was right there waiting for me. I liked that as I wasn't jittery and foaming at the mouth between sets. But again, felt as strong and energized as ever when the time came for it. Flavor was very good. Product mixed well with only a little sediment that mixed with just a quick shake. Nice, clean, honest product!!

PRE has a formulation of 24 active ingredients that combine to deliver a training experience that really did exceed my expectations. the formula is totally transparent so you know exactly what youre getting and in what amounts...there are no mysteries here! i liked the way NutraBio broke it down into different complexes. theres a Power, Strength & Endurance Complex, a Nitric Oxide Pump Matrix, a Focus & Stim Matrix and a Electrolyte & Hydration Optimizer. all of these are dosed in clinically effective amounts that will push you through the toughest, longest workouts! the Blue Raspberry flavoring is spot on and mixes up easily. at 39.99 for 20 servings PRE has a price point that is a bit on the high end but the quality of the product more than justifies the cost. this is an outstanding and very well thought out product!

Apr 14, 2018

***this review is for the Natural PRE version. im normally not a huge fan of Green Apple flavorings but when mixed with 12 oz of cold water i found PRE to be quite tasty. the flavor is crisp and refreshing...much like biting into a green apple off the tree. mixing is pretty much effortless and complete, just a few twists of the spoon or shakes of the wrist and youre ready to go. i loved everything about this Beta Test. the purity and quality of PRE is unmatched and outstanding. the ingredient list includes many of the best and clinically effective components that you can find. energy, focus and pumps are all among the best ive experienced from any PWO product on the market .Naturals PRE is a no-brainer for me, if youre looking to get back to a more natural product...give this a try!

To begin with, this big boy contains a whopping 6g L-Citrulline, 1g Agmatine and 750mg Nitrosigine for the pump (which is incredible) and 3.2g Carnosyn Beta Alanine. Combine this with both Creatine mono (Pharmapure) and Magnapower and you have a product that delivers and keeps you going strong long into your workout. There is a host of other synergistic ingredients like caffeine in various forms and focus blends that really keep you in the game. Taste: Green Apple rivals most other green apple flavors I've had that are artificially sweetened. This is not too sweet and without bitterness that some expect with a stevia sweetened product. It's really a good medium between a granny smith apple and a jolly rancher candy. I was very pleased with the flavor and give it a solid 8 of 10, if not a 9. Mixability: This was the only issue if you even care about complete solubility. I mixed mine up the night before an early 4am workout. Mixed it a 7pm, shook it every 10min or so until I went to bed. In the morning, there were still undissolved particles in the bottom. It wasn't the settling of colors and sediment but actual particles, white, that just didn't want to dissolve. Possibly the creatine as I have noticed that Mono just has a hard time dissolving with other products I have used. It might however be the organic cane sugar as the label says there are small dark particles in it that are normal. Now, this isn't necessarily a bad thing, I just prefer complete solubility to aid in increased uptake and less chance of causing gas. I however didn't notice any GI issues with this. Performance: This is the bright shiny star of this product. This stuff delivers with a sledgehammer of energy, focus, endurance and lasting strength. I'm thoroughly impressed with this aspect of the product. Definitely one of the top 3 pre's I have ever tried.

this review is for the NATURAL version of PRE. taste/mixability: i got the Green Apple flavor and was pleasantly surprised by how close they came to the real thing. the sweet/sour combo is just right and mixes up well in cold water. just a bit of residue on the bottom formulation: total transparency and clinical dosing of proven ingredients makes the formulation of PRE impressive to say the least. i especially liked the 7.8 grams of Nitric Oxide Boosters found in the Pump Matrix. the 18 ingredients used in PRE provide everything you could possibly need for a great workout. effectiveness: when used as directed, a full serving of PRE taken 20-30 prior to training provided me with great energy, focus, strength and pumps. this stuff really does deliver as advertised....nicely done

The new green apple is more strong and is more acid like a granny green apple. Kicks in you after 15 minutes. Give a lot of focus and energy to last a great workout... A great natural product that is easy for the digestion. I'll give it a 10 out of 10 and recommend it to everyone with a natural approach in supplements and sports.

Green Apple is one of my favorite supplement flavors and NutraBio did a remarkable job on the flavoring of their Natural version of Pre. When I'm looking for a complete pre-workout formula that has all of my bases covered, NutraBio is the one I turn to. Fully disclosed labels are a must for me and Pre hits the mark across the board with everything that it contains. Great energy and improved endurance while using this product.

I had the Natural version of Pre in Green Apple. I had previously used the regular Green Apple version and wanted to compare the two. In terms of taste, both were a little different from one another but both were spot on with flavoring. For those looking at the Natural version, you won't be disappointed with how they were able to take the Green Apple flavor and really nail it. With such a packed pre-workout like this one, this always delivered with energy and endurance components for me.

Note: This review is for the natural version of this pre to be launched on soon. I got the opportunity to try this out from Nutrabio and it did not dissapoint. First off, this is the most transparent label I have ever scene even disclosing the amount of stevia flavoring. From a dosing standpoint, this pre is loaded. It has 6 grams of L Citrulline which I believe is the most effective dose. On top of that, it has Nitrosigine and Agmatine. Te pumps I got were really good with this. The energy I got was very clean with no jitters or crashes. Solid energy from start to finish of the workout. The flavoring is on point. I found it not as sweet as artificially flavored pre's but you could adjust the flavor by adding or decreasing water. My only suggestion for improvements are to come out with a non creatine version because I have trouble digesting creatine monohydrate. Overall, a very solid pre that is all natural without the chemicals and stuff you don't want.

I have used this for 20 consecutive workouts, as part of a NutraBio super-stack, throughout the month of January. I have no problem giving this an overall 10/10. FLAVOR is amazing, MIXABILITY is good, PROFILE is top notch as with anything NutraBio, ENERGY/PUMPS were awesome. The PRICE is a bit too high for me to use this as a daily pre, so I would use it maybe 1-2 a week with the next tub. I would like to see less than 300mg Theanine ... I think less of it would increase the kick from the 350mg Caffeine. Overall, this is an amazing pre and I would highly recommend it. If you can get your hands on the Pre Extreme, that is even better! Thank you NutraBio.
