NutraBio Grass-Fed Whey Isolate Flavors Get Upgraded!

Update: A few weeks after this was updated, NutraBio also released their Ice Cream Cookie Dream flavor.

NutraBio Grass-Fed Whey Protein Isolates

Four years after its initial launch, NutraBio has updated their Grass-Fed Whey Protein Isolate, starting with upgraded Chocolate Milkshake and Vanilla Bean Ice Cream flavors, and then quickly adding Ice Cream Cookie Dream!

In 2017, Mark Glazier and his team launched the NutraBio Natural Series to wide acclaim, as consumers were looking for natural flavors and sweeteners. This went beyond the brand’s commitment to all-natural coloring, creating a line of supplements without synthetic ingredients like sucralose.

Their Natural PRE and Natural Intra Blast supplements stole the show that year, but the series was originally launched with Grass-Fed Whey Protein Isolate.

As time passed, NutraBio added new flavors (such as the extremely-underrated Matcha Latte), continually perfecting their commitment to top-notch protein flavoring. But with the launch of NutraBio Plant Protein, we saw a whole new look, and it’s now making its way to the Grass-Fed Whey Isolate as well!

New Label and Flavoring: NutraBio updates Grass-Fed Whey Protein Isolate

NutraBio Grass Fed Whey Protein Isolate Ice Cream Cookie Dream

After Chocolate Milkshake and Vanilla Bean Ice Cream, Ice Cream Cookie Dream was the next flavor to surface!

On July 1, 2021, NutraBio announced not only new labels for this protein, but new flavor systems as well! It starts with a move from Chocolate to Chocolate Milkshake while Vanilla becomes Vanilla Bean Ice Cream. Shortly after, Cookies and Cream was updated and renamed to Ice Cream Cookie Dream, their signature “cookies & cream” variation.

Just like before, this is all about high quality protein and nothing else. There’s no fillers, dyes, excipients, artificial colors, hormones, artificial flavors, or anything else of the sort! If you’re tired of food full of growth hormones, or you’re simply a supporter of ethical treatment of cows, this one’s worth a look.

Grass-Fed Whey Isolate Ingredients

NutraBio Grass Fed Whey Protein Isolate Ingredients

The updated NutraBio Grass Fed Whey Protein Isolate Ingredients and Nutrition Facts — this one is based on Chocolate Milkshake. The Vanilla Bean Ice Cream takes up less powder per serving.

True to form, NutraBio has a fully-disclosed label that gives you all the pertinent info including how much sweetener, flavoring, and thickener is in there!

  • Grass-Fed Whey Protein Isolate (29.07g yielding 25g protein)

    Each serving of NutraBio Naturals Grass-Fed Whey Isolate provides 25 grams of 90% pure, clean protein sourced from dairy cows that have a 100% grass-fed diet – the way they like it. NutraBio uses cold processed cross-flow micro- and ultra-filtered, non-denatured whey protein isolate which provides a full balance of bioactive whey protein fractions.

    Whey protein isolate is incredibly bioavailable with a protein digestibility rating of 95, protein efficiency ratio of 3.6, net protein utilization of 92, biological value of 159 and a perfect 1.0 PDCAAS (Protein Digestibility Corrected Amino Acid Score)![1]

    In addition, we should all know that whey protein can be used by both men and women to improve body composition and increase strength alongside a healthy, high-protein, nutrient dense diet and exercise program.[2-5]

    Does Grass-Fed matter?

    Two Delicious New Flavors… and we bet more are coming!

    The upside to eating grass-fed beef is the better fatty acid content / ratio over standard beef. However, when using whey isolates, all of the fat is stripped out anyway, so it makes many ask if grass-fed isolate really has many health benefits over standard whey isolates?

    There are two ways we see it – first off, there will be less growth hormone inside, which many don’t want to touch. Second, grass-fed cows are simply treated better, so there is an ethical angle to this that many don’t think of. Cows aren’t meant to eat corn and other cheap grains – they’re grass-eaters – and happier and healthier that way too!

    Regardless of the fatty acid profile, a growing niche of the market has grown savvy to the natural movement and don’t subscribe to using products derived from standard dairy cows who are often fed nothing more than industrial waste, and NutraBio Naturals speaks to this crowd perfectly.

  • Natural Sweeteners

    Keeping in line with the high-quality, holistic approach of the Naturals series, NutraBio has included only natural sweeteners in their new powder. Each serving provides 160-170 milligrams of monk fruit extract (depending on the flavor) along with 125mg stevia extract.

    Natural sweeteners — especially stevia — are notorious for lending a bit of a bittersweet flavor to protein powders, but monk fruit extract really smooths things out. This is NutraBio’s second run at these flavor systems, and these natural sweetener extracts improve every year, so we have extreme confidence here in 2021.

  • The rest

    NutraBio flavors protein powders like a champ these past few years

    There’s not much else to NutraBio’s new protein other than 805-1125 milligrams of natural flavoring (depending on flavor), which has been increased since the first version of this protein. The amount of xanthan gum has been reduced (it’s now at 240 milligrams), which is promising as well. This is used to thicken the powder up a bit so that it’s not too thin when mixed with water.


Each serving of the new NutraBio Natural Series Grass-Fed Whey weighs in between 30.4 grams (for Vanilla Bean Ice Cream) and 31.43 grams (for chocolate milkshake) and contains the following nutrition:

  • Calories: 110
  • Protein: 25g
  • Carbs: 2g
  • Fat: 0g
NutraBio Grass Fed Whey Protein Isolate Review

Irresistibly smooth & creamy!

If you’re wondering why fat isn’t listed on the label shown here, read our article titled Supplement Facts vs Nutrition Facts and Protein Powder. NutraBio Was Right (Again). Long story short — because this is a Supplement Facts label, if there’s no fat contributing to the supplement, it shouldn’t be listed at all!

Worth noting is that the near doubling of the natural flavoring has bumped us up a carb. Worth it? Definitely. Better flavor is always worth it when you can burn that carb in less than a minutes of exercise!

Flavors Available

Below is a list of the flavors in stock. If you’re a huge fan of the original Chocolate and Vanilla flavors, stock up while you can – but these boosted flavors are going to be far better anyway:

    NutraBio will likely expand the flavor lineup similar to what they’ve done with the award-winning NutraBio 100% Whey Protein Isolate, which has been 3rd-party certified to be true to label and free of amino acid spiking or any other such label deception.

    3rd Party Lab Tests Available!

    Whey Protein Isolate Done Right

    NutraBio Grass-Fed Whey Protein Isolate

    Grass-Fed – Just like the cows want it. Support the grass-fed economy!

    NutraBio has yet again delivered a superior quality protein that’s not easily matched by any others when it comes to quality and transparency. It’s been quite a while since NutraBio moved to full label disclosure (as explained in our NutraBio Story article), and so few brands are still not doing it to this day. It’s just that much easier when you manufacture your own supplements — something you can also see in our NutraBio Plant Tour videos.

    Grass-Fed Whey is not for all of our cost-crunching users here on PricePlow, but if you’re looking to remove as much artificial-laden, hormone-embedded, unethical food from your life as possible, and you have the money to do so, then this is a logical product to try. Especially given how good NutraBio’s gotten at flavoring protein these past few years.
