Searching for the best protein powders can have you looking at an abundance of options, yet one of our favorites remains whey protein isolate — a bovine-based protein that’s undergone further filtration for elevated purity and fewer carb and fat counts than whey concentrate. (1) These powders can be easier to digest given the lower presence of lactose, with Momentous Grass-Fed Whey Protein Isolate going even further with the inclusion of ProHydrolase, a proprietary blend of digestive enzymes to help curb any gastrointestinal discomfort you may experience post-protein shake. (2)
Momentous Grass-Fed Whey Protein Isolate can be an excellent option for sensitive stomachs, especially when it comes to post-workout protocols near the end of your day. That said, there is a (hefty) price to pay for such conveniences, so in this Momentous Grass-Fed Whey Protein Isolate review, we’ll outline the fine details of this formulation, touch on real-world qualities like taste and solubility, and examine the price of this high-quality protein option. For more information on how we test products for our content, be sure to read our BarBend supplement testing methodology page.
This whey isolate from Momentous offers 20 grams of protein with only 100 calories per serving. In addition to the protein, there's also 90mg of calcium and 115mg of potassium, as well as an enzyme blend to help aid digestion.

As one of the best whey isolates on the market, it makes sense that Momentous Grass-Fed Whey Isolate costs more than your typical whey concentrate. The extra filtration during manufacturing does bump the price up, with many whey isolate powders averaging roughly $1.70 per serving. However, this Momentous protein supplement equates to roughly $2.60 per serving, with each 25-serving container costing $64.95 — a near-$1 increase over the average supp.
While the expensive price tag can be disappointing for budget-minded athletes, it is not without merit once you look at the overall makeup of the powder itself. Not only does Momentous Grass-Fed Whey Protein Isolate contain no artificial flavors, but the whey is sourced from European dairy cows raised under strict regulations free from hormones, steroids, and rBST. Plus, this protein powder is third-party tested by multiple labs and carries certifications from both Informed Sport and NSF.
In terms of the ingredients, this Momentous whey protein supplement doesn’t feature a laundry list of additives. Momentous Grass-Fed Whey Protein Isolate contains up to five ingredients per formulation, depending on your flavor of choice. There’s also an emphasis on natural ingredients, with monk fruit extract, stevia, and natural flavors giving the Chocolate and Vanilla offerings their sweet profile.
This attention to detail and dedication to high-quality ingredients earns high praise from Chelsea Rae Bourgeois, registered dietitian nutritionist and our expert contributor. “I’m a big fan of Momentous’ collaborative efforts with dietitians and appreciate the up-to-date research that backs each formulation,” she says.
Looking at the macronutrients of this best whey protein powder, you can expect 23.3 grams of protein per serving (and zero grams of fat) along with up to 2 grams of carbohydrates. This can help simplify the math when adding a protein supplement to your daily nutritional log and can be a benefit for athletes looking to hit specific counts each day. Other vitamins and minerals listed in the formulation include vitamin D (up to 0.6 micrograms), calcium (100 milligrams), and sodium (up to 145 milligrams). The Chocolate flavor variety also includes 0.7 milligrams of iron as well as 130 milligrams of potassium.
Additionally, each serving of Momentous Grass-Fed Whey Protein Isolate includes 200 milligrams of ProHydrolase. This proprietary blend of digestive enzymes can help support gastrointestinal functions, allowing you to process the protein efficiently without unwanted side effects such as bloating and stomach rumbles, among others. (2)
This added enzyme blend can be helpful when looking to curb the bubble guts, but Bourgeois notes that it is still a proprietary blend, leading to questions regarding actual dosages of the included enzymes. “While ProHydrolase has been shown to be effective, you still don’t get concrete serving sizes when it comes to the included compounds,” she notes. “This may be a turn-off for those that want absolute clarity across their ingredients lists.”
Finally, this grass-fed protein option is available in three flavors — Chocolate, Vanilla, and Unflavored. This flavor roster does limit the variety of tastes, especially when compared to other whey isolates boasting upwards of 20 different flavor variations, but our testers do commend the profiles. “When mixed with milk, it’s an absolute treat,” notes our one tester, a former Olympian. “There’s nothing wrong with a protein playing the hits, in my opinion, and I feel Momentous does just that with this flavor roster.”
Who Should Use / Who Shouldn’t Use Momentous Grass-Fed Whey Protein Isolate
The fact that there are different types of protein lends itself to the notion that not every protein supplement is right for every athlete — Momentous Grass-Fed Whey Protein Isolate included. Below, we’ve outlined a few groups we feel could benefit from adding this powder to their regimen, as well as a handful of camps that may fare better with a different dietary supplement.
Recommended for:
- Individuals looking for a simple protein structure sourced from grass-fed cows without unnecessary ingredients, artificial sweeteners, or preservatives
- Athletes wanting a fast-digesting protein source that’s easier on the stomach
- Competitive strength athletes needing a high-quality whey protein carrying third-party certification
Not Recommended for:
- Athletes avoiding animal-derived protein structures that may prefer a plant-based protein powder
- Those sensitive to natural sweetening agents such as stevia and monk fruit extract
- Athletes looking for a budget protein powder
Our Experience Using Momentous Grass-Fed Whey Protein Isolate
At BarBend, we’ve run the gamut of protein powders — from the best vegan protein powders to the best protein powders for runners, keto athletes, children, and more — testing hundreds of different formulations and varieties over the years. We’ve taken those learnings and practices and applied them to Momentous Grass-Fed Whey Protein Isolate by examining the powder’s full formulation and even working with a third-party accredited lab to assess the supplement’s label accuracy, heavy metal content, and other potential contaminants.
We also studied Grass-Fed Whey Protein Isolate’s real-world performance in the categories of taste, solubility, and (of course) affordability. In an effort to make our findings more digestible (get it?), we’ve also rated this Momentous protein powder in each category on a scale of 1 (lowest) to 5 (highest).
Ingredients and Formulation
The simplified ingredients list of Momentous Grass-Fed Whey Protein Isolate is a standout feature of this supplement, giving you a clear illustration of what’s included in your formulation. The natural flavors, gluten-free makeup, and protein sourced from grass-fed cows combine for a no-frills profile that leaves little question as to what’s within each serving as you aim to reap common protein benefits, such as muscle growth and improved post-exercise muscle recovery. (3)
In addition to the macronutrient breakdown, I appreciate that Momentous includes the full amino acid profile on its packaging. This roster of BCAAs and essential amino acids gives this powder an added layer of clarity that other protein supplements just don’t deliver. While animal-based protein sources are already complete proteins (i.e., containing all essential amino acids), having exact dosages of each building block can give you further peace of mind when looking to supplement toward your goals.
We rate the formulation at 4.25 out of 5, too, given Momentous’ inclusion of ProHydrolase. This enzyme blend can help increase amino acid concentrations post-workout in an effort to boost muscle repair while also aiding in digestion. (2) “I do dock the overall score, though, since ProHydrolase is a proprietary blend,” notes Chelsea Rae Bourgeois, registered dietitian nutritionist and our expert contributor. “It’s a small demerit, but a noteworthy one, especially since Grass-Fed Whey Protein Isolate is very transparent on all other fronts.”
As much as we admire this formulation, though, we do have some precautionary notes. For one, this powder does use stevia as a natural sweetening agent. Stevia can potentially lead to gastrointestinal discomfort in some athletes. (4) Plus, since Grass-Fed Whey Protein Isolate is sourced from grass-fed cows, it isn’t an ideal pick for plant-based athletes or those following a vegan diet. For these groups, we recommend sticking with a vegan-friendly protein powder using some of the top plant sources of protein.
Taste
If you’re turning to protein powder to help fuel your fitness goals, it helps to have a supplement that tastes. Thankfully, our testers found Momentous Grass-Fed Whey Protein Isolate to be an enjoyable treat, rating the taste at 5 out of 5. “I had this once mixed with water and once mixed with milk,” notes our tester, a certified personal trainer. “I definitely prefer the milk base — a trend I commonly see with whey protein powders — but the water blend is also plenty tasty, too.”
Momentous Grass-Fed Whey Protein Isolate is only available in three flavors — Chocolate, Vanilla, and Unflavored. This may be a detriment to athletes that fancy more adventurous flavor notes and offerings found in some of the best-tasting protein powders. That said, we do appreciate that what Momentous lacks in quantity, it makes up for in quality. Plus, the presence of an Unflavored option opens the door for making protein-based smoothies without having too many tastes present in a single blend.
Solubility
Another vital factor that should be present in a high-quality protein is its mixability. Do you really want a full arm workout every time you’re craving a tasty concoction? According to our testers, this powdered supplement blended seamlessly in their best shaker bottles, creating a smooth consistency that featured no clumps or off-putting grittiness. “I even doubled my recipe, placing two scoops of powder in 20 fluid ounces of liquid,” states our tester, a certified personal trainer. “Even then, I was able to achieve a smooth, grit-free mouthfeel.”
We score the solubility at 5 out of 5, too, as the powder’s ability to dissolve eliminates the need for any secondary washouts. This can be a big convenience if you normally take your protein shakes on the go. Plus, that lack of residue can be helpful when it comes time to clean your shaker bottles, too — no leftover product to funk up your cup.
Price Per Serving
If you’re looking for a catch when it comes to this high-quality whey protein isolate, here it is. Momentous Grass-Fed Whey Protein Isolate costs roughly $2.60 per serving, putting it nearly $1 more than the average $1.70 we’ve found in other whey isolates. As such, we rate the price per serving at 1 out of 5.
Thankfully, though, there are ways to save on this otherwise expensive protein supplement. Momentous does offer a ‘Subscribe & Save’ service that cuts the total cost by 25% along with 10% off future orders. In terms of shipping cadence, you have the option of monthly, bimonthly, or quarterly deliveries, so you have some control on how often you replenish your protein stocks.
Third-Party Testing
Third-party testing can be a nice thing to look for when seeking out protein powders. These stamps of approval provide a visual indication that the supplement has gone through independent testing and is free of banned substances — a requirement for strength athletes abiding by specific governing agencies. Momentous Grass-Fed Whey Protein isolate is both Informed Sport-certified and NSF-Certified for Sport, meaning multiple labs have approved this formulation for use among strength athletes. As such, we rate this protein option at 5 out of 5 for the category.
We also employed an accredited third-party lab to test Momentous Grass-Fed Whey Protein Isolate alongside over 150 other samples of some of the best clean protein powders. These findings showed that Grass-Fed Whey Protein Isolate scored in the top 10% of all sampled supplements for label accuracy as well as the presence of pesticides, phthalates, and bisphenols. The powder scored in the top 50%, though, for the presence of heavy metals, earning it a C grade overall.
What to Consider Before Buying Momentous Grass-Fed Whey Protein Isolate
As is the case with any supplement purchase, there are a few factors worth thinking through before finalizing your cart. Below are a handful of considerations we recommend having top of mind as you look to add a high-quality protein such as Momentous Grass-Fed Whey Protein Isolate to your regimen.
- Training Goals: Your fitness aspirations can greatly affect how much protein you should be aiming for each day. The current recommended daily allowance (RDA) for protein is 0.8 grams per kilogram of bodyweight per day, while recent studies suggest that athletes targeting muscle gain should shoot for between 1.2 and 2.2 grams per kilogram of bodyweight per day. (5)(6) Think about your overall goals, how much protein you should be consuming daily, and look for a protein powder that can help you better achieve those metrics.
- Protein Type: There are multiple protein types to choose from, each beneficial to athletes depending on your personal sensitivities. For example, if you’re abstaining from animal-based products, look for a protein powder derived from plant-based sources. Consider your stomach preferences and opt for a powder that aligns with your needs and wants.
- Available Flavors: You’ll need to regularly consume your protein of choice in order to efficiently support your nutritional goals, so finding a flavor you enjoy repeatedly is a near-must. Read through the available tastes and choose an option that’s appealing to your palate. It can also be helpful to look for protein powders with multiple available flavors, as this can open the door to changing up tastes without aggressive fluctuations in the overall formulation.
- Price Per Serving: The average price of whey protein isolates equates to roughly $1.70 per serving. Take a look at your personal finances and determine whether this cost is feasible for your budget or if you need a cheaper alternative such as whey concentrate.
Momentous Grass-Fed Whey Protein Isolate Vs. Competitors
From calorie-rich mass gainers to the best clear protein drinks, there’s no shortage of formulations on the market these days. As such, comparing Momentous Grass-Fed Whey Protein Isolate can be tricky when trying to flip-flop between tabs or crane your neck from one shelf to the next. To make your search easier, we’ve created a side-by-side chart outlining two comparable whey isolates to this Momentous offering — Transparent Labs 100% Grass-Fed Whey Protein Isolate and Nutricost Whey Protein Isolate.
| Momentous Grass-Fed Whey Protein Isolate | Transparent Labs 100% Grass-Fed Whey Protein Isolate | Nutricost Whey Protein Isolate | |
| Price Per Serving | $2.60 | $2 | Starting at $1.23 |
| Protein Per Serving | 23.3g | 28g | 30g |
| Calories Per Serving | 90 | 130-140 | 130-160 |

As one of our long-standing favorite whey isolates, Transparent Labs 100% Grass-Fed Whey Protein Isolate comes in 13 different flavor varieties, each with 28 grams of grass-fed whey isolate per serving. Like Momentous Grass-Fed Whey Protein Isolate, this TL powder carries two third-party testing certifications — one from Informed Choice and the other from Informed Protein. That said, though, we do prefer Momentous’ formulation given the added ProHydrolase, which can be better suited for athletes with sensitive stomachs.
As one of the more budget-friendly whey isolates available today, Nutricost Whey Protein Isolate comes in various container sizes up to 65 servings, which helps keep costs per serving low at roughly $1.23. Plus, I appreciate the myriad of available flavors that mix easily with milk or water. Nutricost Whey Protein Isolate is also third-party tested, although there’s less transparency with this accreditation since the certifying lab is not listed. If you want added clarity, we recommend sticking with Momentous.
Places to Buy Momentous Grass-Fed Whey Protein Isolate

Our Final Verdict on Momentous Grass-Fed Whey Protein Isolate
While certainly not the most wallet-friendly formulation we’ve tested, we feel Momentous Grass-Fed Whey Protein Isolate is a top-notch protein option given its transparent formulation, impressive flavor, and third-party certifications from NSF and Informed Sport. Plus, the addition of ProHydrolase makes this supplement one of the best protein powders for sensitive stomachs. Yes, you’re handcuffed to just three flavor options and the price is well above the average $1.70 per serving, but we’re willing to shell out that extra coin given the performance and transparent qualities at play.
When searching for a new protein powder to add to your routine, think about your fitness goals and how much of the macronutrient you’ll need to consume for optimal support. Take any sensitivities into question, too, so that your regular supplementation is accompanied by unwanted gastrointestinal discomfort. Stick to your budget, find an appealing flavor, and sip away.
Momentous Grass-Fed Whey Protein Isolate FAQs

Yes, Momentous Grass-Fed Whey Protein Isolate can be good for you thanks to a transparent makeup delivering 23.3 grams of protein with minimal carbs and zero fat.
