  • Replenishes and rehydrates*
  • Contains an advanced electrolyte performance matrix*
  • Has zero fillers or additives










Intra-workout amino acids have become a staple for any true athlete for one simple reason: They accelerate recovery. Our team at NutraBio set out to design an intra-workout that relied on the latest research on athletes and decided to take the path least followed when it comes to intra-workouts. Instead of copying everyone else and creating a branch chain amino acid (BCAA) product with some under-dosed "bells and whistles," we created an essential amino acid (EAA) powerhouse. Ironically, this revolutionary formula is loaded with more BCAAs than most of the competition, too!

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. Science-backed 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 therapeutic 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.

INTRA Blast - without question - is the most advanced intra-workout amino acid product ever created.

Every ingredient has an incredible dose that may help accelerate your recovery and fuel your performance.* Take a look at any competitor on the market, and you'll see that they fall short in some area of their formulation. We recognized this and decided to put your recovery and performance first. What we've come up with is a highly advanced formulation built specifically for the performance and recovery needs of any serious athlete. You TRAIN WITHOUT COMPROMISE, and we've put every ounce of effort into creating INTRA BLAST WITHOUT COMPROMISE.

BCAAs are actually EAAs, but there are other critical amino acids to consider besides BCAAs when it comes to repair and growth.* The reason EAAs are considered "essential" is because your body can't synthesize them. Unfortunately, most companies don't use the full EAA spectrum because they are hard to flavor and very expensive compared to just BCAAs. At NutraBio, we don't shy away from challenges, which is why we chose to take on this difficult formulation task to combine the best of both worlds in creating INTRA BLAST. Here's an in-depth look at how the formulation works.

BCAA - Instantized and fermented leucine, isoleucine & valine (7.2 g)

  • These are in the proper scientifically studied ratio of 2:1:1 shown to support recovery and reduce delayed onset muscle soreness (DOMS).*
  • Research suggests that these can spare muscle wasting during prolonged exercise.*
  • In athletes, BCAAs are proven to provide energy to working muscles.*
  • Our BCAAs come from plant sources (fermented) as opposed to animal keratin sources (chemical extraction) such as feathers, hair, etc.

L-Lysine (850 mg)

  • It is a critical essential amino acid that supports protein synthesis and carnitine synthesis.*
  • It is essential to helping the formation of collagens utilized to form connective tissues such a ligaments, tendons and joints.*
  • It is crucial in helping the body utilize calcium for various processes.*

L-Threonine (850 mg)

  • It is a critical essential amino acid that aids in facilitating proper responses to high-stress scenarios created by intense exercise.*
  • Like lysine, it is an essential component to help facilitate proper formation of collagens utilized to form connective tissues such a ligaments, tendons and joints.*
  • It is also critical in supporting proper metabolic function.*

L-Histidine (450 mg)

  • It is a critical essential amino acid, which combines with beta-alanine to form skeletal muscle carnosine to support endurance.* Carnosine plays a crucial role in hydrogen ion buffering and as an intramuscular anti-oxidant.*
  • As a precursor to histamines, it is extremely important for immune response and supporting the role of anti-oxidants.*

DL-Methionine (300 mg)

  • It is a critical essential amino acid that helps the body in synthesizing creatine.*
  • It serves as a precursor to glutathione, one of the most important antioxidant tripeptides formed by the body.*
  • It has the ability to bind with selenium, which is a critical trace element involved in numerous metabolic processes.*

DL-Phenylalanine (300 mg)

  • It is a critical essential amino acid that helps the body repair and support the central nervous system.*
  • It serves as a potent precursor for numerous neurotransmitters that are critical in muscle activation and movement.*
  • It has the ability to affect mood states and has been shown to support positive thoughts.*

L-Tryptophan (55 mg)

  • It is a critical essential amino acid in the formation of numerous neurotransmitters related to mood and performance.*
  • It has also been suggested to have the ability to have a positive impact performance.*

L-Glutamine (5 MG)

  • This is the most prevalent non-essential amino acid in the body, which has shown to affect hydration status of skeletal muscle cells.*
  • It has been shown to have a role in resynthesis of both protein and glycogen.*
  • It also demonstrates the ability to support the synthesis of many compounds critical to energy and repair, such as ATP, DNA and RNA.*


  • 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 suggested to have a positive effect on fat and energy metabolism.*
  • It has also been suggested to have a positive effect on hydration and supports healthy nitric oxide levels.*

L-Ornithine Alpha-Ketoglutarate 2:1 reacted (OKG) (1 G)

  • It has been demonstrated to have a positive role in boosting recovery and supporting protein synthesis.*
  • It can help improve training by diminishing the effects of ammonia build-up from working muscles.*
  • Our OKG is fully reacted, which means it is positively bonded. It is in the exact same form that the positive research studies were based on.


  • It helps maintain proper water balance in the muscle during training due to its osmotic properties.*
  • Supplementation optimizes training endurance and is clinically suggested to support performance.*
  • Supplementation while training helps replace losses of taurine 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.


  • Exercise can deplete magnesium, and it's extremely important to replace these losses attributed to intense exercise.
  • Magnesium is critical in processes related to ATP production, oxygen movement into the muscle via 2,3-diphosphoglycerate (2,3-DPG) and over 300 other physiological processes important to athletes.*

  • 2 Tropical Fruit Punch

The tropical fruit punch flavor is horrible; it is probably the worst tasting supplement I have experienced so far, and surely the worst tasting intra-workout. The profile (nutritional info, ingredients...) as seen on the label looks very good but surprisingly the product itself seem to do little difference when taken during workouts as if it is it not really working especially when compared to other 'simpler' intra-workouts.

Intra Blast is in the tradition of all other NutraBio products: consummate quality and unparalleled transparency. The formula is massive and uncompromising, leading off with a whopping 7.2 grams of BCAAs in a 2:1:1 ratio. This is followed by six other well dosed essential amino acids, a heavy 5 gram dose of l-glutamine, and other ergogens and electrolytes! This intra-workout formula can be no less than a perfect 10 out of 10! Not only is the formula premier, but also the flavoring. The passion fruit is absolutely delightful. It is a great balance of sweetness and tartness! The bold flavor has plenty of levity as well allowing it to be super refreshing. It really nails the natural passion fruit flavor with some added kick! The 24.2 gram scoop mixes easily and surprisingly settles very little. Periodic shaking keeps it homogeneously mixed. 10 on flavor too! It hard to assess effects from intra-workout because, they wouldn't be incredibly noticeable especially from short-term use, but Intra Blast definitely helps me stay hydrated during workout and keeps me wanting to keep working out and work for another sip! It definitely has a formula that can help support physical performance in the gym! 10 for effects. NutraBio does it again with a perfect 10 product!

I have been using this for 3 months now and absolutely love it. I tried other EAA's and intra workout drinks, but this takes the cake! Love Nutrabio as a brand, because they use excellent ingredients and don't use any fillers. I feel more refreshed and less fatigued when I use intra blast. As someone who always goes for green apple flavored things first (its my fav) I wasn't that impressed with the flavoring. Tried the passion fruit next and that was really good. Just tried sweet tea for the first time yesterday and I am hooked!!!!

The product itself is a nice fluffy powder, not like the crack crystal drink. BUT i do not even know if it works because the flavor was AWFUL. Orange Mango was the most disgusting thing, I took one sip and dumped it out. I have never done that with any product before and I have been lifting for 10 years. It smelled funny and i thought to myself, 'ok its just a new product', but i took one sip and EW. helped me resolve this SUPER easily, thank goodness!!

I was very lucky to try a sample of Nutrabio's new IntraBlast Dragonfruit Candy which is their new flavor. It isn't available here yet but to this review is for the Dragonfruit Candy flavor I'll start off with the flavor. This is hands down my favorite flavor of any supplement i've ever used. It tastes a lot like vitamin water. Isn't too sweet, just right for my liking. I actually look forward to taking this supplement because i like how it tastes so much. 10/10 Mixability: When i put it in my automatic shaker cup that spins the liquids, it didn't mix very well. However when i shook my cup up and down, it dissolved just fine. There's a lot of active ingredients in this so it's to be expected. Still in the end, i have zero complains and i imagine if you use the old fashioned shaker cup with those metal balls, it will dissolve right away. 8.5/10 Effectiveness: I felt more energized during my work out. I could lift longer, didn't feel as fatigued as much. And i also felt strong during my entire work out. Usually i get tired fast and towards the end i'll be lifting less weight. IntraBlast definitely helped me get through a tough lifting session and i would definitely use it again. 10/10 Supplements: It has 20 grams of aminos, 7.4 grams of BCAA and 10 grams of EAA energy. It has everything you need to get your energy up and providing your body with the essential amino acids. 10/10 Overall rating 9.5/10

Tried a sample of this (New DragonFruit Candy Flavor). Here are my thoughts: Mixability - 10/10 Mixed completely in shaker bottle with no residue. Mixed with about 24 oz (wanted more to last through the workout). But I've used other NutraBio products and mixed with 12 oz and same thing, no residue. Taste - 8/10 The flavor was a little tart. I actually refer sweeter flavor (I have a sweet tooth), so I wish there was more sweetness from the "candy" side. But, overall it wasn't bad. The one disclaimer I will say is obviously the amount of water will impact the overall taste. I wanted to have as much through my workout as possible, so I mixed the 1 serving with 24 oz of water. The taste would be stronger if I used less water, but I wanted to spread it out. Effectiveness - 10/10 Maybe its because I haven't used supps in such a long time (about a year and a half), but I felt pretty good during this workout. I tried to push it hard to see. I did supersets in all my sets, and I also did very high volume. Not a lot of rest in between sets. Total workout time was 53 minutes of weights and then I did 45 minutes of cardio (steady state elliptical). Overall, I pushed it hard and got through the workout. Enjoyed this and will use again in the future, and also recommend.

I was given the opportunity to try NutraBio's IntraBlast in their new flavor, dragon fruit candy, as well as their preworkout in the same flavor. The flavor was good for both, but I liked it much better as a preworkout. I can't drink anything too heavily flavored during a workout, so I usually dilute intraworkouts quite a bit. I could only use half of a serving, as my shaker only holds 25oz of water, and even with just half it could have been a bit weaker. My workouts aren't long enough to drink the amount of fluid I'd need to mix the whole serving. However, the flavor itself is still really great, sweet, tangy, a hint of tropical but far from overdone. If you don't mind a stronger intra, I'd recommend trying it, just be aware that my recommendation comes off the basis of mixing it weak. Flavor aside, the profile for this product rocks. Fully transparent labeling, you know exactly what you're getting here, 10g of BCAAs and EAAs, as well as 5g of glutamine for muscle recovery, and electrolytes to keep you hydrated. My workout last week was hindered from a bad cold, after yesterday's session I expected to be significantly more sore, so I'd like to think this helped quite a bit.

I was a bit dubious after trying Pre, which despite of the impressive label just did not work for me, but I was pleasantly surprised. During my workout session (boot camp style warm ups, aggression drills, bag rounds) I sweat a lot and burn tons of calories too, so any intra workout which helps me to keep up intensity, assists with hydration and eliminates cramps works for me. I used InKage before (as I love KM's PWO), but I wanted to cut back on caffeinated drinks outside my pwo, so this one had a great profile, mixes well, not overly sweet and drinkability is important. (Having said that whenever I feel something overly sweet few drops of lemon/lime can help to make it tangier and some extra Vitamin C won't hurt, right?).

This stuff smells horrible and it tastes even worse.

May 31, 2018

I didn’t care for this product at all.. It tasted like I was drinking green apple plastic and got me extremely nauseous. At first I thought it was my shaker so I then put it in a plain water bottle and had the same taste results. Threw it away after 2 uses. I was Very disappointed.

this review is for the Intra Blast NATURAL version. Intra Blast is fully 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. i wasnt a huge fan of the Sweet Tea flavor of Intra just didnt sit right on my taste buds. for me, that was the only thing about Intra Blast that wasnt exceptional! like PRE the formulation of Intra Blast is absolutely cutting edge and effective. performance, energy and recovery are all amplifyed by the scientifically proven and transparent ingredient list. the 20 grams of Aminos contain both BCAAs and EAAs which are only found in the best products on the market. when sipped during training i can honestly see why they say that when using Intra Blast you "Start Recovering Before You Finish Your First Set"

This review is for the Natural series Intra Blast in sweet tea I recently tried. My gym time is usually 1.5 to 2 hrs so I really like to stay hydrated. I have long, grueling sessions and I like an intra to keep me going. I can say that Nutrabio's Natural Intra kept me from being thirsty every time I used it; which tells me I was completely hydrated. Not many other products have done that. And the best part is Nutrabio did this with a completely natural, honestly labeled product. They disclose everything; nothing hidded and nothing proprietary. Which means you know exactly what you are putting in your body; which you should. After trying this product, I looked over their website and saw they do a complete line of honest, accurate bodybuilding supps. Solid *** Company righ there!!

***this review is for the Naturals version of Intra Blast. i really liked the Sweet Tea flavoring! i mixed my servings with about 20 ounces of cold water and sipped it throughout my workout. the little dark spots that settled to the bottom kind of freaked me out till i read it was the cane sugar used in the Natural process,,,,nice! unlike alot of Amino products, Natural Intra Blast contains sooo much more than BCAAs. try adding electrolytes, EAAs, glutamine and betaine anhydrous in clinically proven dosages and you have just some of the elements of the formulation. again, NO artificial dyes, flavors or sweeteners are to be found anywhere. loved the enhanced performance, hydration and recovery that Intra Blast provides....theres no doubt that this is a product of the highest quality.

  • 7 Sweet Tea

IntraBlast is loaded with 7.4g BCAA's plus 5g Glutamine, 2g Betaine, and Electrolytes. Need I say more? Taste: Sweet tea flavor has a strong following in the forms on here so I was anxious to try it, even though I'm not a sweet tea person. Well, from what I remember sweet tea tasting like, this is dead on. However, I'm just not a fan of this flavor at all. Sweet tea, to me, goes with BBQ and grilling on a hot day. The last place I expect to taste this flavor is luke warm in a shaker glass as I'm thirsty and depleted of energy. It just doesn't match. Now, if you ice this stuff down and sip it at home on of days or evenings, then I can understand. This, of course, is all user preference and I think it's cool that NutraBio came out with a flavor I've not seen anyplace else and do it naturally. Mixability: This is exceptional. Complete and absolute solubility in a matter of minutes. I mean, NOTHING left but tea colored water. Outstanding!! Performance: Wow, this product hydrates like a beast and definitely helps with longevity and recovery. I could tell an improvement from other intra workouts I've had. Those extra BCAA's really do help.
