    In this world, there are two types of supplement companies: leaders and followers. As you've seen, the newest trend in the industry is claiming "no proprietary blends" and "proper doses." This is certainly a good thing to see, but the reality is that at NutraBio we have been doing this for well over a decade and have been in business since 1996. It's never been a question of when a good time to start being honest is.

    Since we have been honest from day one, the only question we ask ourselves day in and day out is what new innovations we can lead with to better serve our athletes with. We've never created a 40-ingredient proprietary-blended fairy-dusted product that contained over 25% maltodextrin as a filler. What we did do is create the first non-proprietary blended pre-workout that is non-GMO and contains zero fillers, excipients, or additives. We've done this since day one with our original PRE and are continuing this with our expanded family of PRE and PRE EXTREME.

    Every ounce of effort from Team NutraBio has been focused on the singular goal of creating the absolutely most effective and purest pre-workout in existence. We started the no-proprietary blend trend over 15 years ago because we're proud of our formulas. We're focused on creating the best, and we've done just that by creating PRE.


    BETA-ALANINE (as CARNOSYN®) (2500 mg)

    • This ingredient has numerous clinical studies supporting its role as a hydrogen ion buffer and its ability to increase muscle carnosine stores.†
    • Supplementation has shown to increase endurance capacity, reps before failure, and total distance increased in time trials.†
    • Carnosine is a powerful anti-oxidant that has numerous health benefits when it comes to memory and central nervous system communication efficiency.†


    CREATINE HCL (2000 mg)

    • This ingredient works by increasing the body's potential to produce more ATP by increasing skeletal muscle phosphocreatine stores. †
    • Creatine monohydrate does not have the same solubility advantages as creatine HCL, which allows for a lower dose to be equally if not more effective. †
    • The increased solubility of creatine HCL comes from attaching a hydrochloride to the creatine molecule, which lowers the pH. This is the basis for enhanced solubility. †

    L-LEUCINE (2000 mg)

    • This ingredient is the most important BCAA/EAA when it comes to supporting anabolism and limiting catabolism. †
    • By itself, it has shown to increase recovery times and limit delayed onset muscular soreness. †
    • What separated NutraBio's leucine from others is the fact that it is from fermented vegetable sources as opposed to animal-based sources.


    • This amino acid has been shown to increase power and strength output due to its supporting role for the body's creatine production. Essentially, it can help increase your reps with a given weight. †
    • It has been shown to have a positive effect on fat and energy metabolism. †
    • Supplementation has been demonstrated to have a positive effect on hydration and supports healthy nitric oxide levels. †


    • Most creatine is transported into the muscle via a process known as sodium transport across the cell membrane.
    • Creatine MagnaPower® is transported via the ligand-gated cation transport channel, which can potentially allow for less bloating. †
    • Magnesium itself is one of the most beneficial minerals to athletes, serves as an electrolyte, and is one of the hardest to get a full RDA of from diet alone. †


    TAURINE (2000 mg)

    • It helps maintain proper water balance in the muscle while training due to its osmotic properties. †
    • Supplementation optimizes training endurance and is clinically proven to improve performance. †
    • Taking pre-workout taurine helps replace its potential loss caused by intense training. †


    • This advanced ingredient serves as a donor for multiple electrolytes in one shot.
    • Electrolytes serve a crucial role in maintaining water balance throughout the body and facilitating motor neuron function. †
    • We employed this innovative ingredient to ensure that you are loading with sufficient electrolytes to perform at your best. †


    • Research has shown that taking sodium reduces an athlete's susceptibility to thermoregulatory strain and increases exercise capacity. †
    • The more you sweat, the more your body loses sodium, so it's critical to replace it while you are training intensely. †


    AGMATINE SULFATE (1000 mg)

    • This is a form of decarboxylated arginine that can survive liver metabolism to enhance blood flow to working muscles. †
    • It has been shown to have the ability to manipulate pain receptors, which may allow you to train past normal pain thresholds. †
    • We only use a vegan source of agmatine that is derived from fermented plants.


    • This novel and patented form of arginine has been shown in clinical research to be more biologically effective in athletes than arginine HCL. †
    • The greater biological effect of this allows for greater nitric oxide production and blood flow at a much lower level than normal arginine HCL. †
    • The synergistic effect of this ingredient and agmatine with respect to increased blood flow is quite dramatic while you are training and during the post-workout period. †


    This revolutionary complex was designed to help athletes maintain focus and drive while putting themselves through the most rigorous training sessions. You will not find a better feeling and a more complete focus complex anywhere else. Here's what each ingredient does. †

    N-ACETYL L-TYROSINE (1500 mg) - Increases mental alertness and boosts mood. †


    HUPERZINE A (100 mcg) - A powerful focus agent that helps maintain elevated acetylcholine levels. †

    As you can see clearly displayed on this chart, even some of the best-selling pre-workouts on the market claiming to be the strongest formulated pale in comparison to PRE-EXTREME or PRE. Many also lack transparency. 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.

    To help athletes even further, we decided to make a commitment to stop using fillers, excipients, and other potentially unhealthy or unneeded additives. We pride ourselves on purity. We admit, it wasn't easy or cheap to do this, but in the end, even the companies claiming that they don't have proprietary blends can't make this claim. Honestly, it just took some serious investing on our part when it came to R&D to achieve this monumental standard, which is unheard of in the supplement industry. But again, we are athletes just like you and want clean supplements.



    Hopefully by now, we have you looking at your current pre-workout and questioning its formulation. We admit, that's our goal here. So if you still have doubts about PRE, we're going to simply ask you the following questions:

    • Why doesn't your pre-workout tell you how much flavoring and sweeteners it uses?
    • Why does your pre-workout contain additives like soy lecithin when it's not necessary?
    • Why does your pre-workout contain artificial coloring like FD&C Red #40, FD&C Blue #1, etc.?
    • Why does your pre-workout contain silicon dioxide or calcium silicate when it's not necessary?
    • Did you know that PRE and the other 300+ products NutraBio makes DO NOT CONTAIN any of these unhealthy or unnecessary ingredients?
    • Did you know that NutraBio tells you exactly how much flavoring and sweetener you are getting?

    So at this point, if you've read this far, you can see why we are so excited about PRE. To be real with you, we created this because the members of the formulation team at NutraBio are also athletes. Some of us are weight lifters, some of us, like our CEO Mark Glazier, are life-long martial artists, some of us are bodybuilders, and some of us even do CrossFit. At the end of the day, we all just want to train hard and see results, just like you.

    This is why we created the most thorough pre-workout ever created, and even our competitors agree with us. If by now you aren't convinced, all that we ask is that you compare our supplement facts panel to your favorite pre-workout product. Take a long hard look at both of them and ask yourself, who created theirs WITHOUT COMPROMISE? If you're still not convinced, come take a tour of our factory and meet the team. Our doors are always open.
