Momentous Whey Protein Isolate vs Thorne Whey Protein Isolate

Both are NSF Certified for Sport whey isolates with clean labels, so the choice comes down to protein per scoop and digestion. Momentous gives 20 g per scoop with a ProHydrolase enzyme blend and grass-fed European sourcing; Thorne gives 21 g with added bromelain and papain and no soy. Reviewers rate both highly, with Momentous slightly ahead on rating volume and Thorne praised for easy digestion. Athletes who want a grass-fed story and enzyme-assisted absorption lean Momentous; anyone sensitive to soy or wanting a complete amino profile leans Thorne.

  • Choose the Momentous Whey Protein Isolate if you want grass-fed European whey with a ProHydrolase enzyme blend and a lower-calorie scoop.
  • Choose the Thorne Whey Protein Isolate if you want slightly more protein per serving, added bromelain and papain, and a soy-free formula.

What reviewers say

Momentous Whey Protein Isolate

  • 4.7 / 53,700 ratings

Owners tend to be athletes and label-conscious buyers who value the NSF Certified for Sport seal and the short ingredient list. Most report easy mixing and gentle digestion, though some find the flavor mild and the protein per scoop lower than expected.

What people mention
  • CertificationPraisedBuyers cite the NSF Certified for Sport seal as the main reason they choose it over cheaper isolates.
  • DigestionPraisedUsers say the ProHydrolase enzyme blend keeps it from feeling heavy or bloating them.
  • Protein amountMixedSome note 20 g per scoop is less than the 24–25 g typical of competing isolates.
  • FlavorMixedReviewers describe the taste as mild and clean rather than rich or sweet.

Thorne Whey Protein Isolate

  • 4.6 / 51,900 ratings

With 4.6 out of 5 from about 1,900 ratings, buyers mostly praise the taste, the easy mixing and the clean ingredient list. The main complaints are the packet format and the small number of servings per box.

What people mention
  • TastePraisedBuyers say the chocolate flavor is pleasant and drinkable on its own.
  • MixabilityMixedMost say it mixes well, but some report clumps when shaken by hand.
  • PackagingMixedThe packets are convenient to carry, though buyers note the box holds only 14.
  • ValueCriticised

Questions and answers

Which is better for post-workout recovery?
Both work well after training. Momentous pairs 20 g isolate with ProHydrolase to speed absorption; Thorne pairs 21 g with bromelain and papain. Pick Thorne for the extra gram and soy-free label, Momentous for the grass-fed sourcing.
Which digests more easily?
Thorne adds bromelain and papain, plant enzymes that help break down protein, and buyers often mention easy digestion. Momentous uses ProHydrolase, which is clinically studied for absorption. Both are isolate, which is already low in lactose.
Is one better for athletes subject to drug testing?
Both carry NSF Certified for Sport, the certification most pro leagues and anti-doping bodies accept. You can use either with confidence under testing rules.
Which has fewer carbs and sugar?
Momentous: under 1 g sugar and 2 g carbohydrate per scoop. Thorne has about 2 g sugar and 1 g fat. If you track sugar closely, Momentous is the leaner pick.
Is Thorne worth stepping up to over Momentous?
Only if you want the extra gram of protein, the soy-free label, or the added plant enzymes. Otherwise Momentous offers more flavor choices and a grass-fed sourcing story at a similar quality tier.
Which lasts longer per container?
Thorne lists 30 servings against Momentous at 25, so a Thorne tub covers more scoops. Check the actual net weight on each listing, since serving counts vary by flavor.
