Dymatize ISO100 Hydrolyzed Whey vs Thorne Whey Protein Isolate

Buy the Dymatize ISO100 if you want more protein per scoop and a faster-absorbing hydrolyzed whey for post-workout muscle gain. Buy the Thorne Whey Protein Isolate if you want a third-party tested, NSF Certified for Sport product with natural sweeteners and added digestive enzymes, and you don't mind a lower protein dose. Both are well-rated isolates that mix cleanly; ISO100 leans toward athletes chasing gains, Thorne toward tested purity and everyday use.

  • Choose the Dymatize ISO100 if you train hard and want 25 g of hydrolyzed whey isolate with 5.5 g BCAAs per serving for post-workout recovery.
  • Choose the Thorne Whey Protein Isolate if you need an NSF Certified for Sport protein with natural sweeteners and added digestive enzymes.

What reviewers say

Dymatize ISO100 Hydrolyzed Whey

  • 4.5 / 51,300 ratings

Owners rate ISO100 highly for mixing cleanly and sitting light on the stomach, and many use it daily post-workout. The main complaints are price and a sweet, sometimes artificial taste in the chocolate.

What people mention
  • MixabilityPraisedReviewers say it dissolves in water with little grit or clumping.
  • DigestionPraisedMany report less bloating than with whey concentrate.
  • TasteMixedChocolate is liked by most but called sweet or artificial by some.
  • ValueCriticisedBuyers note the isolate price per serving is high.

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.
  • ValueCriticisedReviewers say the packets cost more per serving than scooping from a tub.

Questions and answers

Which is better for post-workout muscle gain?
ISO100 gives 25 g protein and 5.5 g BCAAs per serving in a hydrolyzed form that digests fast, which suits right after training. Thorne's 21 g isolate still supports muscle, but with a lower dose and no hydrolysis.
Which one is third-party tested for sport?
Thorne Whey Protein Isolate is NSF Certified for Sport, so it is screened for banned substances. ISO100 does not carry that certification.
Which is easier on the stomach?
Thorne adds bromelain and papain enzymes and uses natural sweeteners, which some people tolerate better. ISO100 is hydrolyzed and low in lactose, so many lactose-sensitive users do fine with it too.
Is Thorne worth stepping up to over ISO100?
Step up to Thorne if banned-substance testing, natural ingredients and added enzymes matter to you. Stay with ISO100 if you want the higher protein dose and faster absorption for training.
Which has more protein per scoop?
ISO100 has 25 g per serving versus 21 g for Thorne. If you track protein closely, ISO100 closes the gap with fewer scoops.
Do either contain sugar or gluten?
ISO100 has no sugar added. Thorne has about 2 g sugar per serving and is gluten-free and soy-free.
