Momentous Whey Protein Isolate vs Dymatize ISO100 Hydrolyzed Whey Isolate

Buy the Dymatize ISO100 if you want more protein per scoop, faster-digesting hydrolyzed whey, and a huge track record of owner reviews. Buy the Momentous if third-party sport certification and a clean, grass-fed isolate with an enzyme blend matter more than raw protein per serving. Momentous has the higher rating average and the stricter testing story; ISO100 wins on protein density, flavor range and value per serving.

  • Choose the Momentous Whey Protein Isolate if you are a tested athlete or a label-strict shopper who wants NSF Certified for Sport grass-fed isolate with ProHydrolase and does not mind 20 g of protein per scoop.
  • Choose the Dymatize ISO100 if you want 25 g of hydrolyzed whey isolate per serving, 5.5 g of BCAAs, and the most-reviewed, widely available option.

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.

Dymatize ISO100 Hydrolyzed Whey Isolate

  • 4.4 / 514,997 ratings

With nearly 15,000 ratings averaging 4.4, ISO100 is one of the best-reviewed isolates. Buyers praise the taste, the thin texture and how easily it dissolves, and many lactose-sensitive users report no bloating. Complaints center on sweetness and value per serving.

What people mention
  • TastePraisedMost buyers call Gourmet Vanilla smooth and dessert-like rather than artificial.
  • MixabilityPraisedUsers report it dissolves in water or milk with little foam or grit.
  • DigestionPraisedLactose-sensitive users say it causes less bloating than concentrate powders.
  • SweetnessMixed

Questions and answers

Which is better for post-workout recovery?
Both work well. ISO100 delivers more protein and BCAAs per scoop and is hydrolyzed for faster absorption. Momentous adds ProHydrolase and is sport-certified, which matters if you are drug tested.
Which has more protein per serving?
ISO100, at 25 g versus 20 g for Momentous. You would need about one and a quarter scoops of Momentous to match one scoop of ISO100.
Is the Momentous worth stepping up to?
Yes if NSF Certified for Sport, grass-fed sourcing and an enzyme blend are priorities for you. If you mainly want protein per scoop and flavor choice, ISO100 covers that.
Which is easier on the stomach?
ISO100 is hydrolyzed and filtered to remove lactose and fat, which suits many sensitive stomachs. Momentous relies on ProHydrolase enzymes. Try small servings of either first.
Which tastes better?
ISO100 has a long reputation for flavor and a much larger review base. Momentous flavors are well rated but fewer. If taste drives your choice, ISO100 has more to pick from.
Can I use either if I am a tested athlete?
Momentous is NSF Certified for Sport, which many testing bodies accept. ISO100 is gluten free but not sport-certified, so check your program's rules.
