Neither of those accomplish the goals of a true amino acid drink. The true goal is to fuel performance and accelerate recovery.
NutraBio’s Intra Blast contains a perfect blend of BCAAs, EAAs, ergogenics, and recovery agents to help you get stronger and recover better. Now, Intra Blast isn’t an all-new product to hit the market, but they do have a brand new flavor: Orange Mango, and it is fantastic.
We loved the Orange Mango Super Carb that we recently tried (free samples here!) and think this is worth bringing to your attention as now you can get that same great taste before or during your workout.
But flavors aside, Intra Blast is all about the formula.

Intra Blast Ingredients
As you’ll see with every single product in NutraBio’s extensive line of supplements, Intra Blast contains a completely open label – even down to the flavoring and sweetener used!
You’ll find the exact amounts explained in great detail to reassure yourself that you’re getting exactly what you pay for.
Muscle Growth EAA / BCAA (10,005mg)
Branched Chain Amino Acids (BCAAs) are the backbone any amino acid drink, let alone any intra workout product. Intra Blast uses the research-backed 2:1:1 ratio of BCAAs, which means each serving 3.6g of Leucine, 1.8g of Isoleucine, and 1.8g of Valine.
This all totals up to an impressive 7.2g dose of BCAAs that will help stimulate muscle protein synthesis[1,2], speed recovery, and delay the onset of muscle soreness, also known as DOMS.[3,4]
Right off the bat, we’re on to a good start. This is about 50% more than what other products are delivering, but now come the EAAs:
L-Lysine is an essential amino acid that plays a primary role in the body’s production of carnitine, which supports the conversion of fatty acids to energy and reduced cholesterol levels.
More importantly, lysine is heavily involved in calcium absorption, building muscle protein, and recovery from injuries.[5,6]
Threonine is alpha amino acid that’s used in the body’s production of proteins. More specifically, it’s needed for the biosynthesis of glycine and serine to stimulate muscle protein synthesis in the body.
No doubt you’re aware of beta alanine’s reputation as a proven endurance and strength booster. In case you forgot why exactly, beta alanine bind to histidine in the muscle to raise carnosine concentrations in the muscle.
Deficiency of Histidine reduces muscle carnosine levels, so it stands to reason that supplementing with it will increase carnosine levels. You can supplement with all the beta alanine you want, but if you’re severely lacking in histidine you can kiss the benefits of BA goodbye.
To get the most of both ingredients it makes sense to use both to make sure your carnosine levels are always at their top level.
Methionine is a precursor to L-Taurine and L-Cysteine that also acts as a potent antioxidant in the body. It helps the spread of free radicals and oxidative stress that’s brought about by repeated bouts of intensive training.
Also known as DLPA, DL-Phenylalanine is first converted to Tyrosine in the body and then later converted into epinephrine, norepinephrine, and L-Dopa. These 3 big-time neurotransmitters help improve mood and increase energy, both of which will come in handy during grueling workouts.
Tryptophan is the amino acid found predominantly in turkey and chicken that many mistakenly blame for their post-holiday nap. However, clinical trials demonstrate supplementation with tryptophan is able to improve stamina and endurance due to increasing the pain threshold the body can tolerate.
Still, tryptophan is a bit of a relaxant, which is why you see it in a very small dose here – just enough to accomplish whatever biological processes require it, but not so much that it can be used as a sleep aid.
Muscle Recovery Accelerator (5000mg)
Update: We originally had this at “500mg” for a couple of weeks. It is 5000mg – thanks to Adam G for the correction.
Glutamine is well-known, and well-debated, as an amino acid that helps spur muscle growth and recovery. It’s considered a conditionally essential amino acid in that usually your body can synthesize enough to keep up with demand.
However, athletes and weightlifters alike run through their glutamine stores rather quickly and the body’s production simply can’t keep up with demand. This is when supplementing with glutamine is crucial.
Including a healthy dose of glutamine in Intra Blast will go a long way to ensuring proper recovery and allowing you to tackle the competition day after day.
The 5000mg dose here is far bigger than what’s in most intra workouts, which are usually at around 1000-2000mg. So if you’re a fan of glutamine, this is immediately an intra for you to seriously consider.
Strength & Performance Matrix
Betaine Anhydrous (2g)
Betaine Anhydrous, a.k.a. trimethylglycine, has become insanely popular in pre and post workout products on the market. Seeing it as part of an intra workout product is quite a rarity. However, including it here will help you improve endurance, power, and muscle protein synthesis during and after your workout, when it’s most important![11,12,13]
If that’s not enough, other research into betaine shows it reduces muscle soreness.
Note that the clinical dose of betaine is 2.5g, Intra Blast gets you really close with an impressive 2g, but paired with the 1.5g in NutraBio’s Pre Extreme, you’re more than covered to get your daily fill.
You can read more in our informational post titled Betaine: A Safe & Natural Muscle Builder, where we note that even 0.5g could start yielding results – so the 2g per workout here is definitely more than enough to kick off gains!
L-Ornithine Alpha Ketoglutarate (OKG) is a salt formed from the combination of 2 molecules of ornithine and 1 of alpha-ketoglutarate (AKG). Moreover, OKG is a precursor of arginine and nitric oxide.
Greater nitric oxide production leads to greater blood flow in the body which helps supply the muscles with fresh oxygen and nutrients, culminating in better endurance and performance during your workouts.
Electrolyte & Hydration Optimizer
Taurine is another conditionally essential amino acid in the body primarily stored in the brain, muscles and heart. The muscles portion is where we want to focus here.
Taurine causes your muscles to act as a sponge thanks to its role as a cell volumizer, which draws in water and additional nutrients. This not only increases endurance, but also supports “water-based” pumps during your workout.
Lastly, taurine can dramatically reduce DOMS (delayed onset muscle soreness, which everyone inevitably suffers from in one form or another.
Yet another well-dosed ingredient. Normally, you see 1g of taurine – especially when in monster formulas like this. NutraBio went the full nine on this one too.
Calci-K® is a patented blend of calcium and potassium developed by Albion Human Nutrition. These two electrolytes are crucial to maintaining optimal performance during your workouts.
Calcium is required for the formation and maintenance of healthy bones in addition to supporting muscular contraction (especially the heart and skeletal muscles).
Potassium is primarily involved in muscle and nerve function in the body, most notably of the heart. Reduced levels of potassium lead to cramping, delayed reflexes, and fatigue, none of which help accomplish your training goals.
Sodium Phosphate (157mg)
Another of the body’s major electrolytes heavily involved in performance is sodium. If you’ve ever tasted a drip of sweat, you know it’s salty, this is due to the high amounts of sodium that are lost through sweat during exercise.
Losing as little as 2% overall hydration can lead to impaired performance, altered CNS function, and severe cramping.
Di-Magnesium Malate (140mg)
Followers of our blog are well aware of our recent musing surrounding the importance of magnesium, the second most abundant mineral in the body.
Like the rest of the electrolytes in Intra Blast, magnesium is necessary for A LOT of critical processes in the body, namely: protein synthesis, muscle contraction, energy production, and glucose control.[21,22,23]
To ensure your body keeps firing on all cylinders throughout your workout, you need to include all of these electrolytes, and Intra Blast includes them in all the right amounts.
Aside from the new Orange Mango flavor that we already mentioned up top, Intra Blast also comes in Passion Fruit and Fruit Punch.
If you remember from our Super Carb review, Orange Mango was our runaway favorite. This version is no different – we’ve absolutely loved it. It’s solidly flavored without too much artificial sweetener (remember, NutraBio keeps their formulas 110% open!) and isn’t over the top, yet you can add quite a bit of water to make it last.
Intra Blast is awesome, and NutraBio is absolutely on fire with their sports nutrition supplements lately. They’ve long been a top trusted company for vitamins, minerals, and protein… but between this, Pre Extreme, and Super Carb, they’ve just entered the next level.
Whether you’re working out fasted and want to prevent catabolism or looking to fuel your anabolic desires, Intra Blast contains everything you need to fuel your intense workouts in one tasty, well formulate package.
The combination of electrolytes, performance enhancers and amino acids delivers the goods your body needs to go longer and harder while supporting optimal growth and recovery. If you’re looking for a prime intra workout fuel, you’d be hard pressed to find a more appealing option than Intra Blast.
The one issue is that NutraBio’s stuff does cost a bit more, but in the case of budgeting, remember that you’re getting 7.2g BCAAs and can probably do well to use ¾ of a scoop to save money. These guys have shown that they’re worth it.
