BCAA 5000

  • Naturally Fermented & 100% Vegetarian
  • Promotes Protein Synthesis*
  • Supports Muscle Recovery*
  • Boosts Muscle Growth*
  • Helps Preserve Lean Muscle*








BCAA 5000 is NutraBio’s anabolic matrix that combines the powerful muscle recovery benefits of Branched Chain Amino Acids (BCAAs). Collectively made up of Leucine, Iso-leucine, and Valine, the BCAAs are known as essential amino acids because the human body cannot produce them and must be consumed through diet or supplementation. Independently each BCAA plays an important physiological role in the body. However, it is their combination that produces one of the most important processes involved in muscle building and recovery; the process known as muscle protein synthesis (MPS).*

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 clinical dosages of ingredients

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.


We are all familiar with the expression “If it looks like a duck, swim likes a duck, and quacks like a duck, then it probably is a duck.” What does this have to do with BCAAs you say? The fact is most BCAAs found in supplements are derived from duck feathers; and in some grotesque cases human hair. If the thought of that makes your stomach turn upside-down consider this. The BCAAs found in NutraBio BCAA 5000 are all 100% vegetable based and are manufactured through natural fermentation. What’s more, except for flavoring, they have no additives, fillers, or excipients.


Look at 10 different BCAA brands and you will find 10 different ratios from 3:2:1 to 10:1:1 all claiming their BCAA breakdown is the best. Because NutraBio relies on science instead of hype and cheap marketing tactics, BCAA 5000 utilizes the research validated 2:1:1 ratio (leucine, isoleucine, valine) proven to reduce training related muscle damage by stimulating muscle protein synthesis; allowing your body to repair, recover, rebuild, and ultimately have you prepared to tackle your next training session.*


With BCAA 5000, you make no sacrifices – you get proven and powerful muscle building BCAAs, without the junk. We pride ourselves on purity. Each of our BCAA is independently lab tested for purity and potency. What you see on the label is exactly what you get. BCAA 5000 contains no fillers, excipients, proprietary blends, or other potentially unhealthy or unneeded additives.


Athletes, bodybuilders, and fitness enthusiasts alike know the vital role BCAAs play in helping them achieve their training goals. While the extensive list of BCAA supplementation benefits could fill page after page we will look at the top 10 reasons why BCAAs should be a part of your supplement regimen. As a whole BCAAs:

  • Ignite muscle protein synthesis – leading to larger gains in lean mass accretion and faster recovery times.
  • Assist in maintaining an anabolic (muscle building) environment - Exercise can put the body in a catabolic state (muscle degenerating). When this happens BCAAs can be used for energy as opposed to growth and repair. BCAA supplementation can improve nitrogen retention by sparing other amino acid groups; which ultimately keeps the body in an anabolic state.*
  • Support lean mass growth – BCAAs activate satellite cells that travel and attach to individual muscle fibers.*
  • Increase muscle strength - Going hand in hand with benefit #3, increases in lean mass mean large muscle fiber size and greater cross sectional area which equates to greater increases in muscle strength.*
  • Support fat loss*
  • Support metabolic rate for improved body composition.*
  • Increase endurance performance – During prolonged exercise, BCAA’s are taken up by the skeletal muscle rather than the liver in order to contribute to energy production (oxidative metabolism). They also can help prevent muscle damage during long duration endurance sports by protecting muscle tissue*
  • May decrease post exercise soreness – Also known as delayed onset muscle soreness (DOMS); BCAAs help recovery caused by strenuous exercise that is thought to be responsible for DOMS.*
  • Assist in maintaining lean muscle mass during periods of calorie restriction – When calories are cut as a whole this usual means a drop in protein consumption. Not enough protein and muscles may start to atrophy. Studies have shown BCAA supplementation during periods of calorie restriction can assist in maintaining lean muscle mass while also decreasing fat mass.*
  • Support prolonged muscular strength and endurance.*


Do you know where your supplements are made? Do you trust the raw ingredients found in them are really what they are supposed to be and are scrutinized for contaminants before going in to a final product? Unlike 99.9% of our competitors, NutraBio BCAA 5000 (and for that matter all our products) is developed in our own GMP certified and FDA inspected facility. This way, we can monitor every step of manufacturing from start to finish, to ensure the highest quality BCAA supplement is made without compromise. If that wasn’t enough NutraBio uses FT-NIR Spectroscopy to initially analyze every raw ingredient that comes into our manufacturing facility. Every ingredient we receive is immediately quarantined and put into a separate warehouse where it will remain until our Quality Control lab analyses it for identity, purity, composition and potency. The first level of analysis tells us if the ingredient is what it’s supposed be. NutraBio’s ingredient qualification program is rigorous and absolutely no ingredient goes into our supplements unless it passes stringent testing to meet our demanding specifications.

NutraBio is a name you can trust when it comes to clean and effective supplements. Since 1996 we have been setting the quality standard in the world of sports nutrition. Although the industry makes it seems like non-proprietary blends, proper dosing, and scientifically backed ingredients are something new; the fact is NutraBio pioneered this trend over two decades ago. We have always been the innovators; not the imitators.


The essential amino acids Leucine, Isoleucine, and Valine collectively form what is referred to as the Branched Chain Amino Acids (BCAAs). These amino acids are essential because they cannot be produced in the body and must be provided though supplementation or diet. BCAAs comprise approximately 30% of the total muscle protein pool and are the primary amino acids oxidized in the muscle during exercise and catabolic stress. For these reasons athletes supplement with BCAAs for the purpose of increasing muscle mass, recovery, blunting fatigue, and increasing energy during exercise.*

Hundreds of studies exist on the ergogenic benefits of BCAAs. The majority of them show that BCAAs, whether consumed throughout the day or pre, during, or post-exercise; decrease protein catabolism (breakdown) and support muscle protein synthesis…a physiological process responsible for muscle growth and repair. Furthermore, BCAAs are vitally important to glucose (energy) production; contributing to greater than 40% of glucose production during sustained endurance exercise. A study done in 2009 found that subjects who supplemented with BCAAs while following an 8-week resistance training program had a greater decrease in body fat, an increase in lean mass, and greater strength gains on the bench press and squat compared to the non-BCAA group. The BCAAs found in NutraBio BCAA 5000 are in the researched backed ratio of 2:1:1 (Leucine, Isoleucine, and Valine) and come from plant sources as opposed to animal sources such as feathers or hair.*

L-LEUCINE (2.5g)

  • 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.*


  • Isoleucine, like leucine, is another BCAA that can stimulate muscle protein synthesis, but to a lesser when not combined with the other BCAAs.*
  • Isoleucine may also play in role in the fat burning abilities of BCAAs.*

L-VALINE (1.25g)

  • Valine, the third BCAA, promotes muscular endurance and decrease fatigue during exercise.*
  • When exercising tryptophan is converted to serotonin and signals the brain that the body is fatigued…ultimately leading to a decrease in muscle strength and endurance.*
  • Valine competes with tryptophan for entry into the brain, and prevails.*

BCAA 5000 FAQs

What is the best way to take BCAA 5000?

  • Mix one scoop of BCAA 5000 into 16 ounces of cold water or favorite beverage and consume 2 times/daily. For best results take BCAA 5000 between meals to optimize muscle protein synthesis.

Do I really need to take BCAAs? Can’t I just get them through my diet?

  • While you can most definitely get BCAAs through a regular diet high in protein consider this; 5 grams of BCAAs promotes muscle protein synthesis just as much as a 25-30 gram high protein meal. Essentially BCAAs help promote/maintain lean muscle gains and aid recovery without the calories; which might benefit individuals trying to cut or find themselves too “full” to eat another meal.*

How do BCAAs help during training and recovery?

  • BCAAs are the basic building blocks of the human body, including muscle. BCAAs are necessary in our diets in order to repair and rebuild muscle tissue. They also are necessary to maintain energy levels, maintain a healthy metabolism, and other important functions.*

What other NutraBio products would you recommend taking with BCAA 5000?

  • For muscle building and recovery goals we recommend stacking BCAA 5000 with our 100% Whey Protein Isolate and one of our pre-workout formulas such as PRE EXTREME.*

    What makes BCAA 5000 better than other branched chain amino acid supplement?

  • The level of transparency and the 2:1:1 Ratio of BCAAs your body needs to maximize muscle protein synthesis, promote muscle growth, and shorten recovery time.*

I could not be more satisfied. I tried Nutrabio natural flavor but I couldn't deal with it, it tasted horrible. This though, it's incredible. Go with grape!

I've been using this product for about two months. I enjoy the Kiwi Strawberry & Passion fruit flavors. I use a shaker cup to help thoroughly mix. I like that it has pure ingredients with no fillers and has been independently tested that you can verify. Also, it sells at a good price for the number servings per container.

I've been using this as part of a NutraBio super-stack, for about two weeks now. TASTE: 9/10... I like it. It has a sweet-but-not-too-sweet taste, with no chemical taste or aftertaste. FLAVOR ACCURACY: 7/10... This tasted more like a Cotton Candy flavor to me. I tasted no Strawberry or Kiwi in there. The taste is quite pleasant, but it does not resemble Strawberry or Kiwi. Not to my taste anyways. MIXABILITY: 10/10... The powder mixed very very well, with very little foam at the top and no residue at the bottom of the container. I usually went with 2 scoops in 32oz of filtered water. PROFILE: 9/10... I would like to see at least 7g BCAA per scoop, so I ended up double-scooping this (there are 5g BCAA per scoop). Aside from this, this profile is very transparent, as expected from any NutraBio product. PRICE: 9/10... at one scoop, the price would be awesome. Because I had to double-scoop this, the price per serving doubles. Still, there are 60+ servings in the tub, so it's still a pretty decent price. OVERALL: 8/10... Happy with this product. I would buy again for sure. I would suggest a different flavor name - perhaps "Cotton Candy" or perhaps simply "Candy", and perhaps more BCAA per serving.

Great taste and goes down with ease!

It mixes very easily, no clumps or stuff floating around and settling on the bottom of my shaker cup. The flavor was AMAZING. I highly recommend this product to anyone looking for a solid BCAA product.

Great taste, and only one scoop per serving! Mixability is lacking slightly, you really need to shake it up for at least a minute for the powder to absorb. Other than that this is a great BCAA product, with clearly listed ingredients and dosages. Will be buying again.

I love Nutrabio BCAA, its the only brand I know I can have and it works great ! They are not processed on machines that make peanuts, tree nuts, shellfish, etc. Its all pure and made fresh, I buy directly from there site (I want BB.com to start selling there Carbomax due to Nutrabio not processing on machinery with foods I have allergies to). BCAA is a must have and Nutrabio provides great product !

I like Nutrabio's products, but this one never mixes well and the flavor is very light.
