Unbiased Momentous Whey Protein Isolate Review

Many Momentous Whey Protein Isolate reviews say the same thing—natural ingredients, great transparency, and grass-fed whey—justifying the $55 price tag as a premium choice. But once you peel back the surface-level marketing, all you’re left with is a shallow protein powder filled with claims and no substance.

Keep reading my Momentous Whey Protein Isolate review for a no-nonsense breakdown of what you’re actually getting with Momentous Whey Protein Isolate.

🔑 Momentous Whey Protein Isolate Review, TL;DR

If you don’t want to read my full Momentous Whey Protein Isolate Review, here’s your quick cheat sheet.

Transparency Issues – No Proof of 100% Grass-Fed Whey

Momentous claims its whey is sourced from UK and German dairy farms, but there’s no third-party certification to back up its grass-fed claim. 

Unnecessary Enzymes Raise Questions About Quality

Momentous advetrties there whey as cold-filtered. Yet, Momentous includes and advertises ProHydrolase. Which is eye raising because cold-filtered wheys do not need digestive enzymes. This suggests they’re using a blend of grass-fed whey with lower-quality whey, which would explain the two filtration processes they advertise.

Premium Price Without Premium Proof

At $55 per tub, this protein should offer full transparency and verified grass-fed status. Instead, you’re left with marketing claims rather than verifiable data.

Who Should Use This Protein Powder?

• Athletes needing NSF Certified for Sport and prioritizing banned substance testing.
• Buyers who don’t mind taking a brand’s word on grass-fed claims without verification.

Final Grade: 36/50 – 72% Average
Momentous Whey Protein Isolate isn’t amino spiked, but its transparency issues make it hard to justify at this price. Better options exist.

📖 Momentous Whey Protein Isolate Review

Looking into Momentous Protein Review to see if it lives up to its premium price tag? At $55 per tub, you’d expect full transparency, high-quality sourcing, and clear proof that you’re getting what you pay for. But does it actually deliver?

This Momentous Protein Review breaks down everything you need to know—from its grass-fed whey claims to third-party testing and amino acid profile. If you’re looking for 3rd party verification, Momentous checks a lot of boxes: NSF Certified for Sport, cold-processed whey isolate, and an added enzyme blend for digestion. But the deeper you look, the more questions arise.

For starters, where’s the proof that this is truly 100% grass-fed whey? The brand claims sourcing from UK and German dairy farms, but with zero third-party grass-fed verification, no omega-3 data, and no Certificate of Analysis (CoA), there’s no way to confirm how much of this protein actually comes from pasture-raised cows. Compare this to AGN Roots or NorCal Organic Whey—both brands provide sourcing details and lab-tested nutrient profiles.

Bottom line? This Momentous Protein Review reveals that while the product isn’t amino spiked, it’s missing key transparency factors that would justify its high price. If you’re paying for premium, you should get proof—not just marketing claims.

🔑 Where To Buy Momentous Protein, TL;DR

Two solid options for buying Momentous Whey Protein Powder are direct from Momentous Supplements or Amazon.

• Best for Refunds & Payment Flexibility: Momentous offers a 30-day satisfaction guarantee and accepts HSA, PayPal, and ShopPay.
• Best for Fast Shipping: Amazon provides free 2-day shipping for Prime members, but does not allow supplement returns.

Recommendation: If you want a money-back guarantee, go with Momentous Supplements. If you need it fast, Amazon is the better choice.

🛒 Where To Buy Momentous Protein

There are multiple places to buy Momentous Supplements, but I always recommend purchasing directly from Momentous or Amazon. For transparency, I bought my Momentous Whey Protein Powder container from Amazon.

💸 Does Momentous Supplements Have A Money-Back Guarantee 

Yes, Momentous Supplements offers a 30-day satisfaction guarantee. If you’re unhappy with your purchase, you can request a refund within 30 days of delivery.

However, there are some catches. Shipping charges and sample sets are non-refundable, so you’re out of luck if you only ordered a sample pack. While Momentous Supplements claims to stand by its products, it doesn’t specify whether opened containers are eligible for returns. So, if you’re testing a full tub, you might want to clarify before purchasing.

For full details or to start a return, check out Momentous Supplements’ official policy.

Value: 2 of 10.

At first glance, Momentous Supplements checks a lot of boxes—advertised high-quality ingredients, grass-fed whey, third-party testing, and a 30-day money-back guarantee. But when you start examining the details, you’re left wondering if this protein is worth $55. 

🔑 Is Momentous Grass-Fed Whey Protein Amino Spiked? TL;DR

No, Momentous Essential Grass Fed Whey Protein Isolate is not amino spiked. The 11.05% leucine content is within the expected range for a whey isolate, confirming no free-form amino acids have been added.

There are some transparency concerns with Momentous Essential Grass Fed Whey Protein Isolate. It lacks verification for it’s grass-fed claim. The leucine content suggests it’s not a 100% grass-fed whey. If anything, when compared to ON Gold Standard, it’s a lower quality protein powder. After requesting a Certificate of Analaysis (CoA), Momentous Supplements does not want to provide that level of transparency. 

Final takeaway: Momentous Essential Grass Fed Whey Protein Isolate is legit for amino spiking, but label claims remain questionable.

⚛️ Is Momentous Grass-Fed Whey Protein Amino Spiked?

No, Momentous Grass-Fed Whey Protein is not amino spiked. The leucine content sits at 2.21g per serving (11.05%), which falls within the expected range for a whey isolate. A scientific study analyzing protein quality confirms that high-leucine content is a key marker of unadulterated whey protein.

However, transparency is a problem. The grass-fed claim is unverified, and the leucine percentage doesn’t suggest a fully pasture-raised whey source. This raises concerns that Momentous Grass-Fed Whey Protein uses a blend of whey sources rather than 100% grass-fed dairy.

The final takeaway is that it is not amino-spiked but not fully grass-fed either, and without a Certificate of Analysis (CoA), sourcing claims for Momentous Grass-Fed Whey Protein cannot be confirmed.

💪 After Training Shake: How Many Servings of Momentous Whey Protein Powder to Stimulate Muscle Protein Synthesis?

Research indicates that to stimulate muscle protein synthesis (MPS) effectively, you need at least 25 grams of protein with 2.5 to 3.0 grams of leucine per serving. Since Momentous Whey Protein Powder provides 20 grams of protein and 2.2 grams of leucine per serving, you’ll need slightly more than one serving if mixing with water—about 1.25 servings to meet the MPS threshold.

However, USDA information confirms that high-protein (HP) skim milk contains 13 grams of protein and 1.3 grams of leucine per cup. To prolong your tub of Momentous Whey Protein Powder, mix three-forths of a serving (15g protein, 1.65g leucine) with 8 ounces of HP skim milk (13g protein, 1.3g leucine). This combination delivers 28 grams of protein and 2.95 grams of leucine—meeting MPS requirements while extending your supply.

Amino Spiking: 10 out of 10. 

Momentous Essential Grass Fed Whey Protein Isolate earns a 10/10 for amino spiking because the leucine content (11.05%) falls within the expected range for a legitimate whey isolate. 

🔑 Is Momentous Whey 3rd Party Tested? TL;DR

Momentous Essential Grass Fed Whey Protein Powder is third-party tested, but that doesn’t mean full transparency. It holds NSF Certified for Sport and Informed Sport certifications, verifying it’s free from banned substances and contaminants—but not quality or grass-fed authenticity.

Momentous refuses to provide a Certificate of Analysis (CoA), pesticide, or heavy metals test results, only stating that NSF certification ensures “safe levels.” Their grass-fed claim is unverified, with no omega-3 data or third-party certification.

Final word? Momentous Essential Grass Fed Whey Protein Powder passes for safety, but sourcing and transparency are questionable. If you want verified grass-fed whey with full traceability, look elsewhere.

📜 Is Momentous Whey 3rd Party Tested?

🔩 Momentous Protein Heavy Metals

Momentous Whey Protein Powder is NSF Certified for Sport and Informed Sport Certified, meaning it’s tested for contaminants, including heavy metals. However, NSF certification only confirms that heavy metals are below unsafe limits—it does not verify purity levels or disclose exact concentrations.

Momentous does not carry a California Prop 65 warning for heavy metals, which suggests levels are within state safety limits. However, when directly asked for a full heavy metals and pesticide test report, Momentous did not provide one, only restating that NSF certification ensures the product “meets label claims” and is “safe for consumption.”

Without a Certificate of Analysis (CoA) or independent lab results, there’s no way to verify if Momentous Whey Protein Powder has lower heavy metal levels than competitors or just meets the baseline NSF standard.

🐄 Is Momentous Grass-Fed Whey Protein Really Grass-Fed?

When a protein brand claims to be grass-fed, most people assume that means 100% pasture-raised dairy with all the nutritional benefits that come with it—higher omega-3s, better CLA content, and a cleaner, more natural product. But does Momentous Essential Grass-Fed Whey Protein Powder meet those expectations? The short answer: we don’t know, because they don’t tell us.

🧐 Lack of Organic Certification & No Verified Grass-Fed Status

Wouldn’t they want to prove it if Momentous Essential Grass-Fed Whey Protein Powder truly came from 100% pasture-raised dairy? Instead, their support page admits their whey is not organic and does not carry Truly Grass Fed or USDA Organic.

The brand states their whey comes from cows in the UK and Germany, but without third-party certification, there’s no guarantee those cows are exclusively grass-fed. This leaves consumers relying on Momentous’ word alone—and in an industry full of misleading grass-fed claims, that’s not enough.

🧐 No Omega-3 Data = No Proof of Grass-Fed Benefits

One of the biggest advantages of grass-fed whey is its superior omega-3 and CLA content. Unlike grain-fed dairy, true grass-fed whey should retain at least some of these healthy fats, even in whey isolate form.

However, Momentous does not disclose omega-3 content, which is a major red flag. When asked directly, they confirmed that their whey isolate removes all fats, meaning no omega-3 or omega-6 fatty acids remain (source).

Compare this to AGN Roots Grass-Fed Whey and NorCal Organic Whey, which openly share their omega-3 and CLA levels per serving. Wouldn’t they advertise it if Momentous Essential Grass-Fed Whey Protein Powder truly retained any of these benefits? Instead, they leave that data out entirely.

Check out my AGN Roots Review and NorCal Organic Whey reviews if interested. 

🧐 Cold-Processed or Just Marketing Speak?

Momentous advertises cold & micro-processing filtration, but what does that mean? Unlike brands that provide a Certificate of Analysis (CoA) verifying protein integrity, Momentous does not offer one.

Momentous Essential Grass-Fed Whey Protein Powder claims to offer a mix of cold processed and micro-filtration. Which is unusual if this is a 100% grass-fed whey. Microfiltration strips aways nutrients, in this Omega-3s. A duo-filtration of whey makes it difficult to assess if $55 is worth the price of this protein powder. 

🧐 Final Verdict: A Grass-Fed Label Without the Transparency

The details don’t fully add up if you expect Momentous Essential Grass-Fed Whey Protein Powder as a 100% grass fed whey. While they claim whey sourcing from UK and German farms, they fail to provide specific transparency of the following:

• No grass-fed cerification
• No Certificate of Analysis (CoA) to verify processing quality
• No omega-3 or CLA disclosure

So, is Momentous Essential Grass-Fed Whey Protein Powder grass-fed? Maybe—but without full transparency, there’s no way to know how much of its whey comes from pasture-raised cows versus grain-fed sources.

If you’re looking for a verified grass-fed whey protein with full transparency, AGN Roots and NorCal Whey both provide third-party certification and full traceability—and you can easily find them on Amazon.

Momentous, on the other hand, offers no certification, no omega-3 or CLA data, and no sourcing verification. At $55 per tub, they’re asking you to trust their word—but when it comes to grass-fed claims, that’s not enough.

🌱 Grass Fed Whey Protein Reviews

Not all whey protein labeled “grass-fed” is truly grass-fed—and Momentous Essential Grass-Fed Whey Protein Powder is no exception. While Momentous claims its whey comes from UK and German dairy farms, there’s zero third-party verification to back this up. The company openly states that its whey is not organic, doesn’t carry Truly Grass Fed or USDA Organic verification, and provides no omega-3 or CLA disclosure—key indicators of authentic grass-fed dairy.

If sourcing transparency matters, my Truly Grass-Fed Protein Guide breaks down certified brands that provide full traceability. Looking for New Zealand whey protein? My New Zealand Protein Powder Guide covers the few brands that meet the gold standard of New Zealand dairy regulations.

USDA Organic remains the most verifiable option for USA-sourced whey—ensuring no synthetic pesticides, herbicides, or antibiotics. Unlike Momentous Essential Grass-Fed Whey Protein Powder, these options have strict certification and clear sourcing proof. Want a full breakdown? My USDA Organic Whey Protein Guide and Grass-Fed Whey Protein Guide cover which brands deliver on their grass-fed claims—and which ones fall short.

🔑 How Does Momentous Protein Stacks Up Against Other Protein Brands? TL;DR

When it comes to protein quality, price, and certification, here’s how Momentous Protein Drink ranks against the competition:

1. Garden of Life Sport Whey – The only brand with certified Truly Grass Fed whey, higher leucine (2.8g), and probiotics for digestion. However, it blends whey isolate with milk protein isolate, which may not appeal to those looking for 100% isolate.
2. Transparent Labs Whey Isolate – Packs 28g of protein per serving with 2.8g of leucine, offering better protein-per-dollar value than Momentous. However, grass-fed claims remain unverified and have no certification backing.
3. Momentous Protein Drink – NSF Certified for Sport “sourced” from grass-fed whey in the UK and Germany. However, low protein efficiency (20g per serving) and potential whey blending raise transparency concerns.
4. Thorne Whey Protein: This is the weakest option, as it does not have third-party testing, has undisclosed sourcing, and has a Proposition 65 heavy metals warning.

While Momentous Protein Drink has strong certifications, it lags in protein efficiency and transparency. Garden of Life is the best option for certified grass-fed whey, while Transparent Labs offers a better protein-per-dollar ratio.

📊 How Does Momentous Protein Stacks Up Against Other Protein Brands?

When Momentous Protein Drink is compared to other premium whey isolates, key differences emerge in grass-fed sourcing, leucine content, certifications, and price per serving. But does it truly deliver better value?

• Thorne Whey Protein – Lacks third-party testing, has a Proposition 65 warning for heavy metals, and does not disclose its whey source.
• Transparent Labs Whey Isolate – Higher leucine content (2.8g vs. 2.2g) and 28g of protein per serving, but no independent verification of grass-fed claims.
• Garden of Life Sport Whey: This product Uses Truly Grass–Fed whey, offers higher leucine (2.8g), and includes probiotics, but it blends milk protein isolate.

Momentous Protein Drink claims to source its ingredients from high-quality sources and is NSF certified. But does that justify the $55 price tag? Keep reading to find out.

🆚 Whey Protein Powder Comparison: Thorne vs Momentous

The key differences between Thorne Whey Protein Powder and Momentous Protein Isolate are third-party testing, sourcing transparency, and ingredient quality. While both are whey isolates with low calories and digestive-friendly formulations, Momentous backs its claims with independent verification, whereas Thorne relies on internal assurances.

Third-Party Testing and Heavy Metals

Momentous Protein Isolate is NSF Certified for Sport, meaning it undergoes rigorous third-party testing for purity, banned substances, and contaminants like heavy metals. Thorne Protein Powder lacks third-party verification and carries a Proposition 65 warning for potential heavy metal contamination.

Grass-Fed Sourcing and Transparency

Momentous sources include whey from grass-fed cows in the UK and Germany, which follow strict animal husbandry standards. Thorne does not disclose its whey’s country of origin and is not certified grass-fed, leaving buyers to take the brand’s word on quality.

Processing and Ingredient Quality

Momentous uses cold & micro-processing filtration, preserving the amino acid profile while keeping lactose under 1g per serving. Thorne’s formula includes thickeners, which enhance its milkshake-like texture but lower protein density per scoop than higher-yield isolates.

🆚 Whey Protein Powder Comparison: Momentous Protein vs Transparent Labs

Momentous Protein vs Transparent Labs market their whey as grass-fed, but neither provides independent verification. Instead of focusing on unverified sourcing, this comparison concerns protein efficiency, ingredient transparency, and formulation differences. Now, here are three to know about Momentous Protein vs Transparent Labs:

1. Protein Density & Efficiency: Transparent Labs delivers 28g of protein per serving, significantly more than Momentous’ 20g. If you prioritize protein per dollar, Transparent Labs wins.
2. Ingredient Profile & Transparency—Both protein powders use stevia. However, Momentous’ whey processing lacks clarity—why use two different filtration processes? The use of a proprietary digestive enzyme, means its a mix of grass-fed and conventional whey rather than 100% grass-fed.
3. Leucine & BCAAs – Despite grass-fed marketing, neither protein powder offers superior leucine content to standard whey isolates. Momentous provides 2.2g of leucine, while Transparent Labs delivers 2.8g, making Transparent Labs the better choice for muscle recovery.

🆚 Whey Protein Powder Comparison: Momentous vs Garden of Life Protein

Both brands claim grass-fed whey sourcing when comparing Momentous vs Garden of Life Protein, but key differences in leucine content, ingredient transparency, and third-party testing set them apart. So, here are three things to know about Momentous vs Garden of Live Protein:

1. Leucine & BCAAs – Garden of Life provides more leucine (2.8g vs. 2.2g) and total BCAAs (6.0g vs. 4.8g) per serving, making it the stronger choice for muscle recovery.
2. Grass-Fed Sourcing & Transparency—Garden of Life uses Truly Grass-Fed whey, meaning it comes from cows that are at least 95% grass-fed. GoL states it uses a protein blend of whey isolate with milk protein isolate, which may not appeal to those looking for 100% pure whey isolate. Momentous sources are from the UK and Germany, but use of a blend grass-fed whey.
3. Digestibility & Additives – Garden of Life includes probiotics (2 billion CFU Bifidobacterium lactis BL818) and fiber, which may aid digestion. Momentous uses a proprietary enzyme blend but does not fully disclose its whey processing method, making it unclear whether the protein is exclusively grass-fed isolate or a blend with conventional whey.

⭐️ Amazon Whey Protein Review: Momentous Protein Reviews

As of writing this Momentous Protein Reviews section holds a 3.9 out of 5-star rating, based on 231 reviews on Amazon. Here’s what positive Momentous Protein reviews highlight:

• Simple ingredient profile with a smooth, clump-free mix, even when using three scoops.
• Well-received taste.
• A brand that prioritizes transparency in ingredient sourcing.

But what about the negative Momentous Protein reviews?

• A 2025 formulation change introduced an overly sweet taste, frustrating long-time buyers.
• Customers dislike the switch to a cylinder container, making the scoop harder to find.
• Reports of quality control issues when buying from Amazon, with some receiving older products.

What’s My Take on Momentous Protein Reviews on Amazon?

I respect the transparency Momentous Protein Reviews suggests, but I’m not fully sold. Although the brand is high-quality, no official supplier or farm location is provided for its proclaimed grass-fed whey. That’s a major gap in transparency.

Comparing this to Muscle Feast, a brand that openly shares sourcing details and third-party verification (read my Muscle Feast Protein review), Momentous Protein still leaves many unanswered questions.

This premium-priced protein costs $55 per tub, but it’s hard to justify without clearer sourcing confirmation. If Momentous Protein Reviews continue mentioning these issues, I’d like to see a response from the brand addressing these concerns.

🥤 What’s The Best Way To Mix Momentous Essential Protein

⚖️ Does Momentous Essential Protein Come With A Scoop?

Yes, Momentous Essential Grass-Fed Whey Protein comes with a scoop. However, Momentous Protein Chocolate has the heaviest serving size compared to Vanilla and Unflavored.

One full scoop of Momentous Essential Grass-Fed Whey Protein is more than one serving. If you’re measuring accurately, aim for just under a full scoop to reach the intended serving size.

👌 Does Momentous Essential Protein Taste Good?

I shudder whenever I see stevia or one of its chemical names. I don’t know why it’s the go-to natural, zero-calorie sweetener in protein powders, but I’m not a fan. So, does Momentous Essential Grass-Fed Whey Protein contain stevia? You already know the answer.

I was surprised when I took my first sip of Momentous Essential Whey Protein Isolate. Momentous Supplements managed to tone down the sharp, overpowering sweetness that typically comes with stevia. It’s gone, but I didn’t mind drinking this one. As advertised, it’s simply “Chocolate Flavor.”

Mixability: 9.5 out of 10.

I had no issues mixing Momentous Essential Whey Protein Isolate. This is the kind of protein powder you can shake up, run out of the gym, and drink on the go without worrying about clumps. As for taste, Momentous Essential Whey Protein Isolate contains stevia, but I found the sweetness less overpowering than other brands. It’s still there, but it doesn’t dominate the flavor. Overall, I had no problem drinking it.

🔑 Momentous Protein Powder Ingredients, TL;DR

Momentous Essential Grass Fed Whey Protein Powder claims to have a clean, premium formula, but a closer look reveals a different story.

• “Grass-Fed Whey” – Marketed as high-quality, yet most of it undergoes micro-processing filtration, suggesting a blend of grass-fed and conventional whey rather than a true 100% grass-fed isolate.
  
• “ProHydrolase for Better Digestion” – Cold-processed whey doesn’t need enzymes for absorption unless it’s low-quality, over-processed, or using a protein blend.
  
• “No Fillers or Artificial Ingredients” – Technically true, but the formula still includes silicon dioxide (E 551), an additive with uncertain safety due to nano-particle exposure concerns. For a so-called clean product, this is a questionable choice.
  

At $55 per tub, Momentous Essential Grass Fed Whey Protein Powder looks premium on the surface, but the devil is in the details—and those details suggest cost-cutting over true quality.

📋 Momentous Protein Powder Ingredients

Momentous Protein Ingredients’ formulation is designed for easy digestion and mixability while maintaining a clean label. The ingredient list is relatively short, but some notable inclusions—such as ProHydrolase and silica—raise questions and concerns.

The protein source is a claimed grass-fed whey protein isolate. Tt’s hard to confirm if it’s fully grass-fed, but it’s most likelyed a blended conventional whey. The presence of ProHydrolase suggests an emphasis on protein breakdown efficiency, yet digestive enzymes are used in used in high-heat processed wheys.

Here’s a breakdown of Momentous Protein Ingredients and their functions:

Momentous Protein Chocolate
Ingredient	Purpose
Grass-Fed Whey Protein Isolate (22.27g)	Primary protein source
Cocoa	Chocolate flavor
Natural Flavors	Enhances taste and flavoring
Guar Gum	Thickening agent
Salt	Flavor enhancer
Sunflower Lecithin	Aids in mixability and prevents clumping in liquid
Silica	Used as an anti-caking agent
Organic Glucosylated Steviol Glycosides & Organic Rebaudioside A	Natural sweeteners derived from stevia
ProHydrolase (200mg)	Proprietary enzyme blend containing Bacillus sp. & Ananas comosus (pineapple extract) to aid digestion and protein absorption.

💊 ProHydrolase: Enzyme for Protein Digestion

Momentous claims ProHydrolase “maximizes absorption and digestion” in its Momentous Essential Grass-Fed Whey Protein, but does the science hold up?

A 2020 study tested ProHydrolase with whey protein and found no difference in total amino acid absorption compared to standard whey. While ProHydrolase did lead to a faster spike in amino acid levels at 30 minutes, it had zero impact on muscle protein synthesis (MPS) signaling pathways like mTOR and p70S6K—key drivers of muscle recovery and growth.

This raises a bigger question: Why does a “premium” grass-fed whey isolate need digestive enzymes? High-quality isolates are already low in lactose and easy to digest. Yet Momentous heavily relies on ProHydrolase as a selling point, suggesting the protein source may not be as high-quality as advertised.

Momentous charges a premium price while relying on enzyme marketing to boost perceived value. Suppose you’re paying extra for Momentous Essential Grass-Fed Whey Protein. In that case, ProHydrolase isn’t offering anything you wouldn’t get from a standard whey isolate—except for a justification to mask a lower-grade protein blend.

💊 ProHydrolase Side Effects: What You Need to Know

🔬 Why Is Silica In My Protein Powder?

If you’re buying Momentous Essential Grass-Fed Whey Protein Isolate expecting a clean-label, why is silicon dioxide, a budget ingredient, even listed in the ingredients list?

The Role of Silicon Dioxide in Protein Powders

Silicon dioxide is a common anticaking agent to prevent clumping in powdered supplements. It’s GRAS-certified (Generally Recognized as Safe) by the FDA and appears in everything from whey protein to spices. But here’s the question—does a so-called high-quality isolate need it?

What It Means for Quality

• Prevents Moisture Absorption – Helps keep powders from forming lumps.
• Aids Flowability – Ensures smooth scooping and even distribution.
• Covers Up Poor Processing? – A protein powder requiring an anticaking agent could suggest lower filtration quality or an unnecessarily fine powder prone to clumping.

According to the USDA, silicon dioxide is commonly used in cheaply processed food products. Why would Momentous Essential Grass-Fed Whey Protein Isolate, a premium priced protein, use a budget ingredient?

The Bigger Issue: Nano-Sized Silica

FDA research analyzed multiple silicon dioxide food additives. The FDA found that nanoparticles as small as 1-100 nm, mayintroduce long-term health concerns. If a cold-processed whey is using silicon dioxide, then it’s not a 100% cold-filtered whey, offering 100% grass-fed whey. 

Bottom Line

The use of silicon dioxide does not makes sense, especially for a premium priced protein powder. I have more questions and concerns, instead of peace of mind. If the protein is as pure and high-quality as advertised, shouldn’t it mix cleanly without adding additives?

🔬 Is Silica In Protein Powder Bad For You?

If you’re paying for Momentous Essential Grass-Fed Whey Protein Isolate, you expect a premium formula—not an additive under regulatory scrutiny. Yet, silicon dioxide (E 551), the anti-caking agent in this protein powder, is exactly that.

Here’s the issue: EFSA’s 2018 review explicitly states that silica in food contains nanosized particles that could accumulate in organs. The problem? No long-term study proves safety, and EFSA even concluded that current regulations don’t adequately characterize E 551’s particle size distribution. In simple terms: we don’t know what it’s doing in your body long term.

Now, is it outright toxic? No. However, a so-called high-quality protein powder using an additive with these many unanswered questions is a major red flag. If brands want to charge a premium, they should eliminate questionable ingredients—not giving you a reason to second-guess their formula.

So, is silica in protein powder bad for you? It’s bad enough that it shouldn’t be a premium product. If Momentous Essential Grass-Fed Whey Protein Isolate is as good as they claim, why does it need an ingredient with unresolved safety concerns?

🌍 Where Is Momentous Whey Protein Powder Sourced?

According to Momentous Whey Protein Powder, their whey is sourced from European dairy farms in the UK and Germany, where cattle are held to strict regulations prohibiting hormones, steroids, and rBST. The brand emphasizes cold & micro-processing filtration to preserve the protein’s amino acid profile while enhancing digestion with ProHydrolase.

While Momentous Supplements highlight quality sourcing, there’s no certification confirming its whey is fully grass-fed—only that it comes from European farms with higher standards. ProHydrolase raises additional concerns, as true cold-processed whey isolates typically do not require digestive enzymes. This suggests that Momentous Whey Protein Powder may blend grass-fed whey with lower-quality, conventionally produced whey that undergoes micro-processing filtration instead of true cold filtration.

Ingredients List: 7.0 out of 10.

Momentous Protein Powder maintains a clean label, but sourcing inconsistencies and questionable additives hold it back. While the grass-fed portion is cold-filtered, the product undergoes micro-processing filtration, indicating a blend of grass-fed and conventional whey rather than a pure 100% grass-fed isolate.

Momentous Essential Grass-Fed Whey Protein Isolate raises a red flag with ProHydrolase. A cold-filtered whey isolate shouldn’t need digestive enzymes—unless the protein quality isn’t up to par. Two different filtration methods reaffirms the supcision that Momentous Protein isn’t a 100% grass-fed whey. 

Additionally, silicon dioxide (E 551) introduces potential safety concerns, as regulatory bodies have questioned its particle size distribution and long-term health effects in food applications. Why not use sunflow lecithin as the main emmulsifier? The reason why silicon dioxide is used is to improve the bottom line for Momentous Supplements. 

🔑 Momentous Protein Nutrition Facts, TL;DR

At $55 per tub, Momentous Protein Powder delivers a lean nutrition profile with 20g of protein per 100 calories. Still, 70-85% protein-per-scoop efficiency suggests it’s not a high-quality whey isolate. Unflavored offers the best protein-to-calorie ratio at 85%, followed by Vanilla at 75% and Chocolate at 70%. 

Despite its minimal ingredient list, including digestive enzymes raises red flags—cold-processed whey doesn’t require digestive enzymes. This strongly suggests Momentous Protein Powder is a blend of grass-fed whey with lower-quality CAFO whey that has undergone micro-processing filtration.

🥗 Momentous Protein Nutrition Facts

When breaking down Live Momentous Protein offers 20g of protein per serving. Momentous Protein is a solid option for those looking for high flavor that is low in calories.

Below is the full Live Momentous Protein nutrition breakdown:

Momentous Protein Chocolate: Full Nutrition Breakdown
Nutrients	Amount per Serving (28.7)	% Daily Value (%DV)
Calories	100 kcal	—
Total Fat	1.5g	2%
Sodium	150mg	7%
Total Carbohydrates	3g	1%

What Stands Out in Live Momentous Protein?

• Cocoa’s Natural Fiber – The 2g of fiber in Live Momentous Protein Chocolate likely comes from the cocoa ingredient rather than a purposeful fiber addition. Since the vanilla flavor has zero fiber, this suggests Momentous is using a less processed cocoa, which naturally retains some fiber, rather than Dutch-processed cocoa that typically removes it.
  
• Leucine Falls Below the MPS Threshold—At 2.2g of leucine per serving, Live Momentous Protein does not meet the 2.5g minimum required for optimal muscle protein synthesis. Most high-quality whey isolates exceed 2.5g per serving, making this a concern for serious athletes.
  
• Ingredient Transparency—Momentous promotes itself as a premium brand, but the processing method for its whey isolate is not clearly confirmed. Without an official cold-processing statement, it’s uncertain if the protein is as minimally processed as they imply.

🍗 Protein Percentage per Serving in Momentous Protein Shake

So, how does Momentous Protein Shake measure up when examining protein percentage per serving?

Flavor	Protein per Serving (g)	Scoop Size (g)	Protein Percentage (%)
Momentous Protein Chocolate	20	28.7	70%
Momentous Protein Vanilla	20	26.5	75%
Momentous Protein Unflavored	20	23.6	85%
Average Protein Percent Across All Flavors: 77%

With 20g of protein per serving, Momentous Protein Shake Unflavored is the leanest option, at 85% protein per scoop. This makes it the best option for those who want minimal ingredients and the highest protein-to-calorie ratio. Vanilla follows at 75%, while Chocolate sits at 70%, likely due to cocoa and other natural ingredients slightly reducing protein density.

High-quality isolates typically range from 80-90% protein per scoop. Hence, Momentous Protein Shake Unflavored is the closest to a premium isolate. If you want something high in flavor, Chocolate and Vanilla are respectable choices. But those flavors are more in-line with protein percent per serving in a protein concentrate. 

Nutrition Facts: 7.5 out of 10. 

The average amount of protein across all flavors is 75%. If you want the least amount of ingredients and the highest amount of protein per serving, go with unflavored. Selecting a flavor protein, your protein percent per serving goes down, but you’re getting a premium flavored protein powder.

🏁 Momentous Whey Protein Isolate Review – Final Thoughts

After breaking down every aspect of this Momentous Whey Protein Review, it’s clear that while the product presents itself as premium, there are serious transparency issues that can’t be ignored. The brand leans heavily on its NSF certification and grass-fed whey claims, yet without a Certificate of Analysis (CoA) or third-party verification on sourcing, there’s little proof to back up these marketing points.

If you’re considering this protein, here are three take-home messages from this Momentous Whey Protein Review:

1. No Amino Spiking, But Transparency Issues – The leucine content (11.05%) confirms that it’s not spiked with free-form amino acids. However, there’s no certification proving it’s 100% grass-fed whey, and the lack of omega-3 data suggests it may be a small amount of grass-fed whey blended with lower-quality conventional whey.
   
2. ProHydrolase Raises Questions – High-quality, cold-filtered whey isolates don’t need digestive enzymes. The use of ProHydrolase suggests that this is not a premium protein offering high-quality ingredients.
   
3. Premium Price Without Premium Proof – At $55 per tub, not advertised claims are not meet. Verified quality of grass-fed, Omega-3 profile, minimal ingredient profile without potential health concerns. 

Final verdict? Here’s the conclusion with this Momentous Whey Protein Review—marekting hype without the verification. 

✅ Is Momentous Protein Good?

If you take Momentous at face value, it checks a lot of the right boxes—grass-fed whey, third-party testing, and a clean formula. But once you start digging into the details, the cracks start to show.

For starters, the grass-fed claim is unverified. Unlike truly grass-fed brands that provide omega-3 and CLA data or certifications like Truly Grass Fed, Momentous offers zero proof. Without a Certificate of Analysis (CoA), you’re left taking their word for it.

Then there’s the digestive enzyme question. A high-quality, cold-filtered whey isolate shouldn’t need additional enzymes for digestion. The fact that Momentous includes ProHydrolase suggests possible over-processing or a lower-quality protein blend.

At $55 per tub, is it worth your money? Not really. While it’s not a terrible option, there are better proteins with more transparency at a lower price. Brands like Transparent Labs and Garden of Life Sport offer higher protein per scoop and verified grass-fed claims, while AGN Roots provides full third-party certification.

Who Should Buy It?

• If you want NSF Certified for Sport and prioritize banned substance testing
• If you’re okay with an unverified grass-fed claim and just want a standard whey isolate

Final Score: 36/50, 72% – Average

Momentous Protein isn’t amino spiked, but it lacks full transparency. For the price, you can get better options with verified sourcing and a higher protein percentage per serving.
