Momentous Whey Protein Isolate (Unflavored)

1. Ingredients 35% of the rating 4 of 5

   Two ingredients, whey isolate and 200 mg of a named protease enzyme blend; flavored versions add natural flavors and sweeteners.

2. Independent testing 35% of the rating 4 of 5

   NSF listing plus lot reports showing lead under 0.05 µg and an independent CR result of 0.15 µg on an earlier version, but the reports are maker-paid.

3. Sourcing 10% of the rating 2 of 5

   “European” and “grass-fed” are stated with no country, farm or certifier.

4. Trust 10% of the rating 3 of 5

   Two 2021 lead notices named its operator for unnamed supplements; it publishes every lot, but through a lab it pays and with an affiliate program.

5. Value 10% of the rating 1 of 5

   $3.50 for 25 g of protein, the highest of the powders we reviewed and well above others with the same NSF listing.

The rating, 3.4 of 5, is the weighted average of these scores. See how we rank protein powders & shakes and our standard.

• Paid certification NSF Certified for Sport

  Lists the unflavored powder (id 1518123; 590 g, 23.6 g scoop, lot field “All”). NSF’s program checks banned substances, label accuracy and contaminants against its own limits, which Consumer Reports describes as 10 µg a day for lead. Open ↗ (opens in a new tab)

• Maker’s own test Light Labs, for Momentous August 2026

  Certificate for unflavored lot 0241H6 (made 20 Aug 2026), per 23.7 g scoop: lead under 0.050 µg, arsenic 0.030 µg, cadmium 0.005 µg, mercury under 0.020 µg. Protein 20.8 g for 20 g claimed. Salmonella, E. coli and S. aureus absent. A second certificate, lot 0235D6 (made 30 May 2026), reads lead under 0.050 µg, arsenic 0.030 µg, cadmium under 0.003 µg and mercury under 0.020 µg per 23.6 g scoop. Light Labs sells testing to brands and lists Momentous as a customer. Open ↗ (opens in a new tab)

• Independent Consumer Reports October 2025

  Tested Momentous Whey Protein Isolate, Vanilla, a version Momentous has discontinued: lead 0.15 µg, arsenic 0.17 µg, cadmium not detected per 26.5 g serving. CR did not test the current unflavored powder. Open ↗ (opens in a new tab)

• Independent Clean Label Project 2025 protein study (a nonprofit that also sells certifications) 2025

  Bought 165 protein powders off the shelf and had them tested by an ISO 17025 lab. Its list includes “Momentous Essential Whey” (flavor and size not stated). It is not among the Clean Sixteen powders that were non-detect for lead, cadmium, mercury and arsenic, which CLP says does not mean a product exceeds any limit. CLP publishes no per-product figures, so we have no number. Open ↗ (opens in a new tab)

Is there lead in it?

The unflavored lot we opened had lead under 0.050 µg a scoop. Consumer Reports (opens in a new tab) found 0.15 µg in an earlier vanilla isolate and 2.33 µg in Momentous’ 100% Plant Protein, which it told CR is discontinued. Two 2021 Prop 65 lead notices name its operator for unnamed supplements.

Are the lot reports independent?

No. Momentous orders them from Light Labs, a lab that sells to brands and lists Momentous (opens in a new tab) as a customer. The outside check is the NSF listing.

What is ProHydrolase, and do I need it?

The certificate calls it a blend of proteases from Bacillus and pineapple, 200 mg a scoop. Momentous says it helps digestion. We did not look for trials of it. It is why the label is two ingredients, not one.

Is the whey really grass-fed and European?

Momentous says so, and says the cows get no hormones or antibiotics. It names no country, farm or certifier, so we could not check.

Do influencers earn money from it?

Momentous runs an affiliate program, linked in its site footer, so some online praise earns a commission. We found no named owner or investor tie to an influencer.

• NSF’s Certified for Sport database lists Essential Grass Fed-Whey Protein, Unflavored (id 1518123; 590 g, one 23.6 g scoop, 20 g protein; the lot field reads “All”). Momentous says every finished batch is certified.
• Momentous posts a certificate of analysis for each lot. The unflavored lot we opened (0241H6, made Aug. 20, 2026) reports per 23.7 g scoop: lead under 0.050 µg, arsenic 0.030 µg, cadmium 0.005 µg and mercury under 0.020 µg, with no Salmonella, E. coli or S. aureus. A second unflavored lot, 0235D6 (made May 30, 2026), also reads lead under 0.050 µg.
• Consumer Reports tested an earlier Momentous whey isolate (vanilla, since discontinued) in 2025 and found 0.15 µg of lead per serving, about 30% of its level of concern. Momentous told CR it has since overhauled its dairy and plant powders.
• The unflavored label is two ingredients: grass-fed whey protein isolate (23.4 g) and ProHydrolase, a protease enzyme blend (200 mg). Momentous says there are no gums, fillers or artificial sweeteners.

• It is the most expensive whey on our list: $69.99 for 25 servings, about $2.80 a serving or $3.50 for 25 g of protein. Subscribing takes 25% off.
• The certificates are paid for by Momentous, which is a customer of the lab that made them, Light Labs. They print “Report Only” where a limit would go. The NSF mark is an outside check, but NSF’s lead limit, 10 µg a day as Consumer Reports describes it, is far looser than CR’s 0.5 µg.
• “Grass-fed” and “European dairy farms” are the maker’s words. No certifier, farm or country is named.
• It adds an enzyme blend. Flavored versions add natural flavors with monk fruit and stevia, and strawberry uses Reb M, a stevia sweetener, and juice powder for color.
