100% WHEY PROTEIN CONCENTRATE (WPC80) – Tried & True since 1996

Two decades ago NutraBio launched a protein powder that was so simple and honest it makes you wonder why it took the industry so long to catch on, our 100% Whey Protein Con- centrate (WPC80). This product has never been protein spiked and never contained proprietary blends, fillers or excipients. Now, 20 years later, it stands tall as the industry's standard for clean, affordable protein with full label disclosure and absolutely no BS. It is truly a classic, which is why we just renamed it "Classic Whey."


It's made from the highest quality form of whey concentrate known as WPC80 and is just 10% lower in protein than our elite 100% Whey Protein Isolate. Our Classic Whey contains only WPC80 and is not blended with any cheaper whey concentrates like sweet whey, WPC34, WPC45 or any other garbage. This supplement has NOT been amino or nitrogen spiked. As always our label has full disclosure so you know exactly what you're putting in your body. Another example of how NutraBio has been looking out for you for 20 years. Clean, honest supplements from the brand that never compromises.

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 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 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.

Non-denatured. Low-Carb, Low-Fat, Instantized USDA Kosher Whey.

Classic Whey contains non-denatured whey protein concentrate that is guaranteed to be the freshest and purest protein available. It contains no fillers, additives or preservatives and is the purest and most affordable whey protein concentrate available. It is OU kosher certified, with a low glycemic index and is safe for diabetics and bariatric dieters. It is a less expensive alternative to whey protein isolate.

Classic Whey Uses Only The Highest Grade Whey Protein Concentrate:

NutraBio uses only 100% non-denatured whey protein concentrate with absolutely no acid treated whey. We use a low temperature cross flow micro filtration process. Low temperature processing protects the protein and keeps the protein fractions intact giving you the highest concentration of muscle building amino acids. Our protein is manufactured in the USA in a USDA licensed dairy plant with absolutely no additives, fillers, sweeteners or artificial anything. Our whey is instantized and agglomerated for greater absorption and bio-availability.*

High Biological Value and Protein Efficiency:

Classic Whey is rich in Branched Chain Amino Acids and provides the perfect profile of Essential, Non-Essential, and Conditionally Essential amino acids that your body requires for optimum nitrogen retention, protein synthesis and muscle growth.*

Advanced Complete-Spectrum Amino Acid Profile:

This is the purest grade; non-denatured whey protein concentrate made from 100% American made USDA Grade A milk. This product contains no artificial sweeteners or flavors and no added sweeteners, fructose, L-Tryptophan, salt or acid-treated whey. Other than whey protein which comes from milk, this product contains no animal-sourced ingredients. Although this protein is 97% lactose free, we recommend our Whey Protein Isolate which is 99.5% lactose free for lactose in intolerant individuals.

No Additives or fillers:

Classic Whey is made from 100% Whey Protein Concentrate (WPC80) that has NOT been blended or diluted with any cheaper proteins like sweet whey or WPC34. Classic Whey has no added sugars, excipients (like silicon dioxide), creamers or other fillers. Other than whey protein which comes from milk, this product contains no animal-sourced ingredients. Classic Whey is 97% lactose free, however if you are lactose intolerant, we recommend our Whey Protein Isolate which is 99.5% lactose free.


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 Concentrate" so our unflavored version contains absolutely nothing but whey protein WPC80, and out flavored versions contain a small amount of flavoring, that's it.

Good nutrition but I have an electric mixer and this protein still had clumbs which ruined it for me. Nobody wants to be consuming clumps every time they have a protein shake. Flavor was good but very plain.

This cake batter bro, let me tell you... this is by far, hands down, the best tasting protein this side of the Mississippi. I blend this bad boy with some mixed berries and milk, and I can feel this protein sauce all up on my taste buds, satisfying and stimulating every aspect of my central nervous system. I don't even need to eat candy when I have this freaking cake batter explosion of greatness pour into my soul. There is nothing better to follow up with after a hard lifting sesh at the glorious house of gains. You, cake batter protein, are my sky rocket in the night, and my afternoon delight.

Kind of bland taste. It’s not an intense flavor. Mixes nicely, does not taste bad

Apr 07, 2018

I enjoyed the flavor, could tell a difference between this and your normal vanilla flavors. I've noticed some cake batters taste very similar to your normal vanilla flavors. I mixed with water, almond milk, 2% milk (yummy) and a mix of milk and water. While not bad at all mixed in straight water, the almond milk or a form of regular milk really gives it a nice flavor and texture. It also worked well making pro-oats and sludge. Did not get any chemical taste from it which was a big bonus! Did not have any issues mixing this product up, mainly was used in a large shaker with a blender ball, rarely had any clumps. Solid profile as shown above, the ratio of protein to fat and carbs works fine for me, I like that the product is 3rd party tested. This was the first product I tried from this company but I've already purchased a couple of others to try based on the quality of this one!

Seems like a decent whey. Could use more of a chocolate taste.

I used two flavors of the Classic Whey as part of a month-long log on the forums: Cold Brew Cappuccino and Cake Batter. The TASTE and TEXTURE are great and very accurate. MIXABILITY is excellent mixed in a shaker cup or a mixer - no issues there. As with all NutraBio products, the PROFILE is nothing short of amazing! You always know exactly what you are getting with each scoop: no surprises and "no compromise". The PRICE is a bit steep in comparison to other brands, but I realize quality costs more. I would say that if you see any NutraBio product on sale, you should take advantage of it. I sure am glad I did!

First and foremost, NutraBio does not have any GMO ingredients, protein spiking, or any other "mystery" ingredients. What you see, is what you get. I was fortunate to try the Cold Brew Cappuccino flavor for free and NB didn't disappoint. Smooth, coffee flavor and it's a joy in smoothies. I'm a coffee junkie so I was quite hesitant on trying to see if they nailed the flavor and they did. I also use this in Fairlife's 2% milk and it's awesome in that as well. I highly recommend this product if you are looking for a nice clean Whey to help with your specific goals. Once again, I am truly grateful for the NutraBio crew for allowing me to try this out.

The taste is amazing! It reminded me of the beach i went to this year. It tastes pure, and I drank it in about 5-10 seconds, and went down great. I recommend this taste for a change . Ingredients consist of Whey Protein Concentrate (non-denatured) (37.2 grams WPC80 yeilding 25 grams complete protein) (CFM cross flow micro-filtered. Cold processed.)

By far the best, cleanest protein I've ever tried. Mixes super easy in a shaker and the taste is awesome! I've tried vanilla and chocolate and both are great. It's also awesome to know this company honestly believes in their product and cares for their consumers

I've gone through a few flavors of this Classic Whey but a couple of them are not sold in this store but the Cold Brew Cappuccino is so I'll give my feedback on the other flavors as well. The ingredient profile is really top notch and they list EVERYTHING that's in here as well as how much of each ingredient. The protein is pure whey concentrate BUT this is a WPC80 which is of the highest quality concentrate you can get and not many companies go as far as to tell you what type of concentrate your getting but NutraBio does and only uses the WPC80 in this product. The mix ability of this type of whey is not the greatest and that's just the characteristic of this protein cause I've noticed in other brands protein blends that use WPC80 they also have a few particles floating but this one from NutraBio is all WPC80 so it definitely doesn't mix that well so I strongly recommend using a blender ball when having a shake. The taste of the Cold Brew Cappuccino is pretty good and it has a light coffee taste that gives the impression that it has milk blended with it. I scored this an 8 on taste because I've gone through two other coffee flavored proteins recently that just had a much stronger coffee flavor and I felt they were better. I've also gone through the Lemon Meringue Pie and the Horchata flavor and both were decent where the lemon was good but just to weak in flavor and you really didn't get any type of pie taste from it and the Horchata was a more unique type of light cinnamon rice kind of flavor which was pretty good. Overall you really can't beat this excellent profile but I think NutraBio needs to try to do something about the mix ability of this protein cause the lemon mixed horribly and I feel they need to tweak the flavors somewhat to make them slightly stronger so the flavors can really come through a bit more intensely. I would have given this a solid 10 if those two things I mentioned would have been better.

I mixed this up just randomly during the day to try this flavor, I have never seen a protein with this flavor. Like the 100% Whey Isolate, mixed it with a spoon and mixed up perfectly. No clumps, dissolving issues, nothing but smooth horchata protein. I have never had this flavor before but it wasn't bad at all, light and something actually delightful beside a regular vanilla, which is what I tend to go with. I liked it a lot. This protein is a non-denatured whey concentrate which is still giving you 75% protein per scoop. And the advantage here is there are more flavors and the price point is more appealing.

I love the fact the label literally shows down to the milligram. Can't get more transparent than that. Taste is good though I mix it with banana and honey and haven't tried it alone.

My favorite protein supplement by far! Chocolate Milkshake tastes exactly like its name, and the Strawberry flavor reminds me a lot like Nesquik. The labeling doesn't mislead you whatsoever and it tells you everything. No hidden ingredients, no spiking etc. The price is fair but I wish to see more discounts on this product in the near-future. I also hope BB adds more of Nutrabio's other flavors such as "Chocolate Peanut Butter" or "Salted Caramel"

I have already finished a tub, I think I wouldn't be looking somewhere other than this product. There is really no need more than WPC-80... It is thicker and tastier, more healthy than isolate, and It gives the same results. The taste is really good for a chocolate, it needs a bit more shaking than usual to dissolve, but not clumpy at all ! It is a bit thick which is cool. And better than all, it is clean ! You know what you are talking if you take Nutrabio.

Out of all the whey products I have tried over the years, this is the best by far. The flavor is excellent. I feel satiated and nourished after having a scoop. I mix it in 8oz of unsweetened vanilla almond milk with 1tsp of ceylon cinnamon and it tastes great.
