Whey Protein is well known as the most powerful source of protein for building muscle. However, there are different types of whey; the most common are Whey Protein Isolate and Whey Protein Concentrate. Whey Protein Isolate is 90% protein by weight and is the purest form of whey that exists, which is why it’s the only protein we use in this product. Whey Protein Concentrate is a cheaper grade with 11% less protein than whey isolate and a lot more fat, cholesterol and lactose. NutraBio’s Whey Protein Isolate contains only Whey Protein Isolate with absolutely NO whey concentrate or other proteins.

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 therapeutic 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.

100% Whey Protein Isolate with Absolutely Nothing Else.

NutraBio Whey Protein Isolate contains 100% Whey Protein Isolate only! There is No whey concentrate or other proteins, maltodextrin, dextrose, creamer or any other filler in this product. It is lactose free, fat free, cholesterol free, gluten free, BSE/TSE free, filler free, excipient free, non-denatured and kosher. These days, the market is flooded with protein brands and to compete companies use confusing labels and deceptive claims to hide cheap ingredients in their products. It’s almost impossible for the consumer to figure out what they are really getting. We make it simple by providing full label disclosure. We never hide cheap ingredients in deceptive proprietary blends. Our labels are simple, honest and disclose every single ingredient along with the exact dosage. Our label doesn't state "100% Whey", it states "100% Whey Isolate" so our unflavored version contains absolutely nothing but whey protein ISOLATE, and out flavored versions contain a small amount of flavoring, that’s it.

To Make the Best Protein You Must Start With The Best Ingredients:

Our factory fresh whey protein isolate (WPI) contains 25 grams of pure protein per scoop and is lactose free, fat free and cholesterol free with less than 1 gram of carbs making it the perfect choice for low-carb dieters or athletes who want to get ripped while packing on muscle. Our WPI is 100% pure, non-denatured, non-acid treated whey isolate with absolutely no whey concentrate, ion exchange, or other cheaper forms of protein blended in. Whey protein isolate has the best overall amino acid profile, biological value and protein efficiency for building muscle.

I heard and read so much about this brand and I wanted to give it a try. I chose vanilla flavor and I was very disappointed! I don't understand how are people giving it 9 and 10 review! It's too light and there is a bit aftertaste, the artificial sweetener flavor is not good. I don't know how am I gonna finish the bottle. The protein ration is very high, probably the highest in the market, and the quality is very high too, no doubt about that. But they need to work on their flavors because I think it's as important.

The premier features of Nutrabio's whey protein isolate is the strength of the brand behind it; quality ingredients, the availability of third-party testing results, manufacture in a cGMP facility, and an ingredient label that goes to the point of listing its contents per serving down to the MILLIGRAM. Some might find that a gimmick in a world where there is a certain mount of slack in the tolerances of a packer, but I appreciate the intention and attention to detail. Mixability is excellent -- a couple of shakes in the usual Blender Bottle and it's mixed completely smooth. No grit or clumps. Texture is also excellent -- I like using whey isolate as a post-workout shake, and appreciate textures that aren't unnecessarily thickened with excessive amounts of gum or creamer. It's easy to digest and easy on the palate after a hot summer garage workout. Taste is also a bright spot. With whey isolates, some might find them a bit bland. Nutrabio is a very tasty vanilla that is easy to drink and rich enough to leave you satisfied and continue to come back to the product. Creamy up front with a slight marshmallow-like aftertaste.

Got it for the wife and she loves the flavor. The ingredient list is clean and no added junk. Got samples and even those are great.

What's not to love? Great profile and a minimal ingredient panel. No artificial junk and the vanilla flavoring is quite good, especially for an isolate. I mostly cook with my proteins or mix it with oats or cream of rice and this was AWESOME for those uses. Made some great protein pancakes as well. Subtle flavor - not buttery or maple-y which can happen with vanilla sometimes. Tastes very much like vanilla bean ice cream. It's not the cheapest protein available of course, but the quality is top notch and this is definitely one of those situations where you get what you pay for. Will definitely use again!

The protein mixes very well. If you are into the nutrition aspect, then its the perfect protein for you because it's high protein, low carb, and contains no soy. I would recommend this for anyone looking to improve their diet.

This is one of the smoothest isolate proteins I have had. Was very light and had No clumps whatsoever. Love the full disclosure of the label. This protein has a ton of good things going for it such as lactose, gluten, and soy free. Others are low carbs, calories, and sugar. The sweetener sucralose was used which is not the best, but is better then others. The taste of the CPB is not the best, but is tolerable. You also need to remeber that the more flavor you get, the better chance it comes from more carbs/sugars. Overall I really liked this protein and will probably try out the other flavors.

like the vast majority of reviewers i thought 100% Whey Protein Isolate was a great product, well worthy of the NutraBio name. the Vanilla version was very tasty, not too sweet or intense and no aftertastes, one of the best isolate flavorings that ive experienced. whether in milk or water this protein mixed easily and completely. i love the non prop formulation, what you see on the label is exactly what you get. outstanding macros and a minimum of super clean ingredients designed to maximize muscle growth makes NutraBio 100% Whey Protein Isolate one of the standout products in its class!

In milk and other usages, the NutraBio cookies and cream flavor certainly was enjoyable for me and will continue to use the tub in that manner. In water I didnt prefer it, so i wont be in any rush to use it in water again. Overall though I would still recommend. Price point is 29.70 servings for $39.99 which comes out to $1.38 per scoop which is on par with other isolates. Also the open label NutraBio uses for every product can keep us consumers at ease at what we are putting in our body and what amounts, you can even get the third party test results for each tub. Ill certainly be testing out the other flavors of the isolate offered by NutraBio. T

NutraBio 100% Whey Protein Isolate is super clean and awesomely effective. the total transparency shows you exactly what youre getting and perhaps more importantly, what youre NOT getting. NO soy, lactose, gluten, or hormones and zero fats. Protein just doest get any cleaner or purer than this. the Alpine Vanilla flavor is really good, perhaps a bit on the sweet side but nothing over the top. like all the NutraBio proteins that ive tried, this Isolate mixes up effortlessly in whatever medium you choose. my personal favorite was in Fairlife...soooo tasty! i also mixed it in my morning Oats for an added shot of muscle building protein. when you find a product thats 90% Protein by weight you know that its super clean and that fillers and additives have been kept to an absolute minimum. this is what you get with NutraBio 100% Whey Protein Isolate....nice job!

if youre looking for a quality 100% Isolate you really cant do much better than NutraBio. from its fully transparent formulation to its outstanding quality and purity....everything is top notch. i got the Dutch Chocolate flavor and was very happy with it. it mixed up easily in both water and 2% milk...with the texture and flavor much nicer in the milk. this is just the nature of all Isolates and not a knock in any way shape or form. the chocolate flavor was subtle but very nice....more of a milk chocolate in my opinion. the macros of this protein are outstanding. 25 grams of protein, zero fat, 1 gram of carbs and only 110 calories make NutraBio 100% Whey Protein Isolate a great choice anytime but really the perfect protein for cutting. granted, this isnt the cheapest Iso out there, but it very well might be the best!! very highy recommended!

Being an isolate, this is on the thinner side, but the flavor is still there. I dont find it crazy overpowering, but its strong enough for you to know that its a Cinnamon Bun. The aftertaste, crazy as this may sound, is my favorite part. The mouth feel and aftertaste are probably the best that ive had in an isolate. Another homerun for Nutrabio

this 100% Whey Protein Isolate is a super clean, top of the line product. i love the full transparency and 3rd party testing. No soy, lactose, gluten, or hormones...just a pure product from grass fed sources. i got the Dutch Chocolate flavor and like all Iso's, it mixed up on the thin side with a light flavor. no clumping or residues at all. this is super solid product with a profile and formulation that can stand on its own against any product in its class!

I couldn't ask for a cleaner protein powder and if you look at the label, the full disclosure, including the sweeteners, is on a whole different level from anything else on the market. If you are looking for a very clean formula that is going to give you exactly what the label says, NutraBio is the way to go. The powder is really fine and mixes great with either water or into something like oats. It's very versatile and the highest-quality isolate I have ever used.
