GAME OVER. NUTRABIO DOMINATES THE PRE-WORKOUT LANDSCAPE

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.

ALWAYS THE INNOVATORS, NEVER THE IMITATORS.

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 (AS CARNOSYN) (3.2g)

  • 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.*

PHARMAPURE CREATINE MONOHYDRATE (3g) & CREATINE MAGNAPOWER (500mg)

  • 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 ANHYDROUS (2.5g)

  • 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.*

DL MALIC ACID (1.2g)

  • 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 (1g)

  • 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.

INOSITOL ARGININE SILICATE (AS NITROSIGINE) (750mg)

  • 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.*

L-TYROSINE (1.5g)

  • 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 ANHYDROUS (250mg) and INFINERGY DI-CAFFEINE MALATE (100mg)

  • 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.*

THEAPURE (L-THEANINE) (300mg)

  • 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 (2g)

  • 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 PHOSPHATE CITRATE (CALCI-K)(525mg) & SODIUM PHOSPHATE (189mg)

  • 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.*

I received a 4 serving tub of the new Cherry Limeade to try out and review and I've used other flavors of this PW in the past so I'm no stranger to the effects. This is a loaded formula with a 30gm serving and a fully disclosed profile so you know exactly how much of every ingredient is dosed even the sweeteners and flavoring amounts is disclosed which is something no other company goes to the length to do. For a 30gm serving the powder mixes very well and I noticed very little foam and you do get a little bit of residue and sediment which is expected when your dealing with such a big serving. The cherry limeade flavor is a very refreshing flavor which for me was pretty dominant on the tangy lime flavor and was a bit mild on the cherry. I tried this on different water amounts from 14oz to 20oz and I preferred it with more water and the flavor still came through strong. The apple for me was my favorite flavor which I rated a 9/10 and Cherry Limeade, Fruit Punch, and Blue Raspberry are all 8/10 and Watermelon a 7/10 but honestly with the hefty dose of ingredients I think Nutrabio did a decent job flavoring all of them. The energy on this kicks in very smooth and even though it has 350mg of caffeine it really doesn't hit hard because the HUGE dose of L-Theanine keeps the energy pretty tamed. If I were to change anything on this PW it would be the L-Theanine dosage from 300mg down to 100mg so that I could feel the energy and focus a bit better. The performance that you experience on this PW is EXCELLENT where the pumps, power, and endurance are there each and every time you use it and though the energy isn't mind blowing it remains consistent throughout your workout. There is a good reason why this PW has remained in the top 5 when it comes to conventional pre's because of the excellent performance effects. I definitely recommend giving this PW a try if your looking for a fully dosed PW without exotic stimulants and one that delivers good energy, pumps, power,and endurance without any energy crash or stomach issues later in the day and you DON'T need to add anything to this PW because it has everything already dosed well.

Please note this review is for Cherry Limeade … Taste - 8/10. The flavor was most definitely cherry and lime but was not nearly as tart as I was expecting and hoping for as I prefer my preworkouts with a sour bite. Now don't get me wrong the flavor was good and I could drink it on a regularly, it was just a bit sweeter then you'd think cherry limeade to be, even mixed in a minimal 12 ounces of water. Mixability - 7/10. As noted I mixed at a minimal 12 ounces of water for best flavor, but at this level the healthy 30 gram scoop is not completely mixed in, even at 16 ounces there is still some residue left over that even a couple swirls don't completely pick up. Function - 9/10. Here is where I was greatly impressed, starting with the label. Why the label? Well because EVERYTHING is listed and the dosages are immense. I don't find much use for any pre that's a 10 gram scoop I mean seriously. So I typically take my pre 30 minutes prior to getting to the gym as I feel I've been losing usage in the beginning or finishing up before I've used up all the benefits. Pre does not hit hard despite its solid dosage of Beta-Alanine and caffeine which was another very pleasant surprise and doesn't give the superman feels of over stimmed products, it just simply works and once you do, you can feel it doing its thing. In my last 3 workouts prior to my first powerlifting meet this past Saturday, my focus and energy were crazy high even with my serious case of nerves. My rest requirements and recovery between sets were better then ever. Even with the monster pump, lactic acid felt to be flushed really quick. Results wise, well I saved my last scoop special for my meet and was able to set PRs on bench and squat with great energy and focus for nearly 3 hours and never any crash post workout. Due to Pres smoothness, disclosed dosage and my personal results, this pre really needs a regular home in my gym and you should put a tub in yours too!!! My overall rating is a 9/10 as that function is just such a big deal.

I got to try this thanks to Kon_Rock with a nutrabio promotion however with the Cherry Limeade flavor that isn't out yet. Lets start with the flavor. When i first opened it, it instantly smelled great. You could tell the flavor was cherry limeade and it made me excited to try it. The flavor tastes amazing! The scoop is very large for a single serving, so you need to make sure to use a lot of water. Also make sure to shake it a long time to make sure it completely dissolves. I rate it a 9/10. Effectiveness: I had a ton of energy while using this product. I felt good, focussed and able to keep giving it my all in the gym. It has everything a pre workout needs. 10/10 Nutrabio pre workout is amazing and i definitely recommend it. Has all the best ingredients you can ask for. It has 350 mg of caffeine so it's a pretty strong pre workout that will definitely give you a lot of energy. As well as all the other ingredients for faster recovery, strength and energy. You can't go wrong with this one. Overall rating 9.5

Probably the most complete pre-workout formula that I have ever seen and had the opportunity to use. When looking for a product that has all of the key muscle building ingredients, this is definitely it. A fully disclosed label also shows you that each one is dosed properly and thus why each serving size is so massive. This pre-workout provides great focus & stamina as I continually experience great workouts when consuming this prior to training.

NutaBio and their generous representation Kon_Rock afforded me the opportunity to beta-test their new flavor, cherry limeade, of their impressive and comprehensive pre-workout! NutraBio PRE is sold in five different flavors in the bodybuildingcom store (blue raspberry, green apple, raspberry lemonade, tropical fruit punch, and watermelon). I've tried each of these flavors and enjoyed each one! However, NutraBio has now put together a new flavor for fans due to popular demand: cherry limeade! This cherry limeade flavor is by far the best of this flavor lineup! It is incredibly refreshing when enjoyed in ice cold water and the flavor is a nice balance between the sweetness of the cherry and the sourness of the lime. There is a little bit of an aftertaste from all the active ingredients in the formula but it is very mild. I put the flavor at a 9 out of 10! Those who are familiar with NutraBio know that they are dedicated to delivering high-quality supplements with unparalleled transparency. This is eminently true of their pre-workout, NutraBio PRE. PRE comes in 20 serving tubs with each serving a whopping 28.70 grams. The product is chocked full of ergogenic aids, amino acids, nitric oxide boosters, B-vitamins, electrolytes, and nootropics. As described above, it is a comprehensive and impressive formula that provides an excellent balance between acute and long-term active ingredients that prioritizes improving exercise performance over simply providing a shock to the CNS. The dosing of the formula hues closely to the clinical-dosing used in scientific studies and features an interestingly strong dose of l-theanine (300mg) with a strong dose of caffeine from two different sources. Each serving is $2, which is about twice as expensive as your typical pre-workout, but this is a formula that earns that price tag. It is a clear top-notch 10 out of 10 formula that I endorse without reservation. The only caveat is that it can be a lot to throw at one's stomach all at once so try a half-serving at first, especially if one is unaccustomed to heavy-scoop pre-workouts. NutraBio PRE effects are completely consistent with the hefty formula. It delivers real performance benefits, especially in terms of enhancing energy and focus while boosting muscle-pumps. I think the best of PRE's effects come through with muscle pumps. It really appears to help with boosting nitric oxide levels. The focus and energy effects are very nice too. PRE is also a standout as a pre-workout because it is one of the few that improves with more use. The strength and endurance benefits really begin to come through with consistent use at the end of a full tub or into the second tub. Effects are a 10 out of 10. NutraBio PRE is a must-try! It is an excellent pre-workout that will really add to a tough workout regimen! Taste (cherry limeade): 9/10 Formula: 10/10 Effects: 10/10 Cost-Value: 8/10 Overall: 10/10

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!

***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!
