NUTRABIO 100% WHEY PROTEIN ISOLATE.
ULTRA-CLEAN PROTEIN WITH UNQUESTIONABLE PURITY.
WHY SETTLE FOR ANYTHING LESS WHEN YOU CAN HAVE THE BEST?
NutraBio 100% Whey Protein Isolate is scientifically designed to provide 25 grams of clean, pure protein derived solely from 100% Whey Protein Isolate, which research has shown to ignite muscle protein synthesis, promote optimal nitrogen retention, and accelerate muscle growth and repair. Our Whey Protein Isolate contains no whey concentrate or other inferior proteins and no amino spiking, added carbs, maltodextrin, dextrose, creamers, or any other fillers; just pure cross-flow ultra-filtered, non-denatured whey.
NutraBio 100% Whey Protein Isolate was the first product we launched when we opened our doors 20 years ago and from day one, we have never hidden cheap ingredients in deceptive proprietary blends. Our labels are simple, honest, and disclose every single ingredient along with its exact dosage. Our label doesn't state "100% Whey," it states "100% Whey Protein Isolate" so you know you are getting absolutely nothing (except a small amount of flavoring) but whey protein ISOLATE, the highest quality, cleanest, and fastest digesting protein available, proven to help you build muscle, recover faster, and train stronger.
What you WILL FIND in each serving of NutraBio 100% Whey Protein Isolate:
A protein with full label/ingredient disclosure
25 grams of complete, high-quality protein derived from 100% WHEY PROTEIN ISOLATE ONLY, gram for gram, the purest form of protein available

A protein that is developed in our own GMP-certified and FDA-inspected facility. 99.9% of our competitors can't make this claim. We have total control of our whey protein isolate from start to finish.
What you WON'T FIND in NutraBio 100% Whey Protein Isolate:
Proprietary blends or amino spiking. We provide full label/ingredient disclosure on our 100% Whey Protein Isolate. No games, no tricks-just the purest, freshest whey isolate available.
Inferior sources of protein, such as low quality whey concentrates or soy that, gram for gram, are not as pure as whey isolates
Extra amino acids like taurine or glycine used by some brands to boost nitrogen content and fool you into thinking you are getting more protein than you really are
Ion exchange or acid-treated whey, which destroys the natural non-denatured state of whey, causing it to lose its anti-cancer and immune stimulating activity
Fillers, excipients, maltodextrin or dextrose, added sugar or carbs, artificial colors, GMOs, or banned substances
No other macronutrient is more essential to muscle growth and recovery than protein. Research shows that active individuals need 1.5-2.2 grams of protein per kilogram of bodyweight daily for optimal nitrogen balance and to promote muscle growth/recovery. This amount is often difficult to meet through a balanced diet, which is why individuals often turn to whey supplementation to support their protein requirements. However, not all whey proteins are created equal. In a market saturated with hundreds of whey proteins, it is hard to know that what you see on the label is what you are actually getting. Many companies use confusing labels and deceptive claims to hide lower quality proteins and cheap ingredients. Therefore, full label disclosure, quality, digestion rate, and preparation method should all be considered before selecting a whey protein.
The most common forms of whey are whey protein isolate and whey protein concentrate. Whey protein isolates digest and absorb rapidly and are, gram for gram, the purest form of protein available (90% pure protein). This level of purity is achieved through a cold cross-flow micro- and ultra-filtration process that removes the larger, less-absorbable protein molecules while also filtering out fat, lactose, and ash that can be present in whey concentrates and substandard protein powders. Furthermore, this process does not denature the valuable proteins and peptides in whey, so the protein itself is of a higher quality.
Studies suggest the ingestion of fast-acting protein sources, such as whey isolates, can increase amino acid levels in systemic circulation and stimulate robust increases in protein synthesis, arguably the most important physiological factor in existence when it comes to muscle growth, strength, and recovery. What's more, since whey protein isolates are generally low in carbs, lactose free, fat free, cholesterol free, and gluten free, it makes it the perfect choice for low-carb dieters, lactose intolerant individuals, or athletes who want to get ripped while packing on muscle. Simply put, isolates are the king of the whey protein jungle.
On the other hand, whey concentrates contain less protein on a gram for gram basis. The process used to create whey concentrates does not go through as many fine filtration steps, resulting in a product that can be anywhere from 25-80% pure protein. Furthermore, whey concentrates, due to the filtration process used, contain higher amounts of fat, cholesterol, and lactose, the last of which may cause gastrointestinal distress and bloating in some individuals.
When taking a product containing whey concentrate, it may be a guessing game as to how much pure protein you are getting per serving. Look closely at the label-unless it says whey protein concentrate 80 (WPC 80), you may be getting a lower quality protein, cheating you of the muscle building and recovery benefits of a higher quality protein. Unfortunately, using lower quality whey concentrates in a protein powder is a common tactic used by unscrupulous supplement companies in order to pad their bottom lines at your expense. The label may still proclaim 100% whey, but the quality of that whey may be as little as 25% pure protein. In summary, whey concentrates are a lower quality and cheaper grade protein compared to whey isolates, and it is best to avoid using products that contain a whey concentrate where the purity is unknown.

Whey Protein Isolate FAQ
When is the best time to take NutraBio 100% Whey Protein Isolate?
We suggest consuming one serving immediately post workout when your body is in need of critical nutrients to maximize muscle protein synthesis, which ultimately leads to muscular growth and recovery. It can also be consumed between meals to meet daily protein requirements.
Is consuming too much protein bad for your kidneys?
Absolutely not. This is a myth. There is no scientific literature that shows that eating a high-protein diet has any detrimental effects on renal function in otherwise healthy individuals.
How should I stack NutraBio 100% Whey Protein Isolate with your other products?
We suggest taking one of our versions of PRE 30-45 minutes before your workout, Intra Blast during, and 100% Whey Protein Isolate immediately after.
Can't I meet my daily protein requirements through a regular diet?
While it is possible to meet daily protein requirements through a balanced diet, some individuals find it difficult to get the 1.5-2 grams per kg/bodyweight necessary to maximize muscle growth and promote recovery. This is why individuals often turn to whey protein supplementation as a convenient way to meet their individual protein needs.
Are whey isolates superior to higher quality whey concentrates such as WPC 80?
Yes and no. Whey isolates are 90% pure protein while higher quality whey concentrates will be ~80% pure protein, making isolates "superior" on a gram for gram basis. However, both forms of whey digest rapidly and help support muscle building and recovery goals. At the end of the day, which one you choose really depends on your goals. If you need a protein that is lower in calories and free of fats, lactose, and cholesterol, go with an isolate. On the other hand, if you need a protein that is more calorie dense and fat laden, which may be beneficial when weight gain is the goal, choose a high-quality whey concentrate. Just be sure the label makes clear that the whey concentrate being used is at least 80% pure protein.

Purchased the vanilla and LOVED it, however, tried the chocolate after because I'm usually a chocolate guy and I wasn't a fan of it. After I get this 5lb. tub down, I'll be trying the cookies and cream.
Written by Stuart from Knoxville, TN
Quality ingredient profile, good taste. This is my favorite protein that I've been able to find with the best combination of price and quality. Would love to see more flavor variety but I do like the Dutch chocolate flavor best so far. I generally have 2-3 scoops/day and never get tired of it.

I love this Whey Protein. I am still in a fat loss stages of my fitness but I was looking for a way to get extra protein to maintain muscle growth without having to drink 32oz of post workout shake. I add 2 scoops of unflavored whey protein isolate to 16oz of water shake and then add 2 scoops of my favorite flavored protein to the same 16oz. Taste is excellent and I get the extra protein I was looking for with only 220 extra cals AND NOTHING ELSE. Best part for me is I don't have to drink 32oz of post shake after each workout. I started adding this to my morning Java Protein as well and it has really worked for me. Since I started doing this I have maintained my weight while dropping 1" off my waist line. Super happy with the quality and taste I just ordered more.

I started bodybuilding/weight-training almost 40 years ago. I have used every protein supplement around. The NurtaBio Isolate is the only protein supplement that does not lay in your stomach. It seems to get utilized quickly, leaving you without feeling bloated. Muscle ache seems to be minimized and it tastes great with water. I have met Mark Glazier at several events. He seems genuinely intent on bringing the best products to market. I look forward to trying some of Nurtabio’s other supplements.
