Dymatize ISO100 has two things no other mainstream protein powder matches at the same time: hydrolyzed whey isolate (the fastest-absorbing protein format in powder), and a Fruity Pebbles flavor that actually tastes like Fruity Pebbles. The licensed cereal collaborations sound like a gimmick until you try one — they’re the reason ISO100 has the most loyal flavor following in a category where most products taste interchangeable.

Quick summary

ISO100 is the fastest-absorbing mainstream protein powder and has the most distinctive flavor range in the category. 25g protein, ≤120 calories, hydrolyzed isolate, banned substance tested. The cereal license flavors aren't gimmicks — they actually deliver.

  • ISO100: 25g protein, ≤120 calories, ≤1g sugar — hydrolyzed whey isolate for fastest absorption
  • 5.5g BCAAs and 2.6g leucine per serving — strong muscle protein synthesis support
  • Banned substance tested across the ISO100 range
  • Licensed cereal flavors (Fruity Pebbles, Cocoa Pebbles, Cinnamon Cereal) — the brand's actual differentiator over ON Gold Standard
  • Elite 100% Whey is the budget option — concentrate/isolate blend at lower cost per gram

Dymatize ISO100 Hydrolyzed Whey Isolate

25g protein, fastest absorption, the cereal flavor lineup

The Data

The Pro Tip

Fruity Pebbles is the most accurate licensed cereal flavor in the protein powder category — it tastes like the cereal dissolved in milk. It works better with water than most protein powders do, because the fruit flavoring carries through cleanly without dairy masking it. If you’ve been buying plain chocolate or vanilla and dreading every shake, this single flavor is worth switching brands for.

The Honest Critique

The hydrolyzed advantage is real but often overstated. Hydrolysis pre-digests protein into smaller peptides, which absorb faster than standard isolate. In practice, the absorption speed difference matters most for elite athletes training multiple sessions per day or people with digestive sensitivity to whole proteins. For a recreational gym-goer having one post-workout shake, the practical benefit over a standard isolate like Isopure Zero Carb is minimal. ISO100 carries a price premium for the hydrolysis — know whether you need it before paying for it.

Dymatize Elite 100% Whey

25g protein, concentrate/isolate blend — the lower-cost option

The Data

The Pro Tip

Elite 100% Whey is the right Dymatize product if you want the brand’s quality standards at a lower per-gram cost. The concentrate component makes it creamier and more filling than pure isolate — some people find this preferable for post-workout shakes. The flavor range is narrow (three options) but all three are well-reviewed.

The Honest Critique

Limited flavor differentiation. Three flavors versus 13+ on ISO100. If you’re drawn to Dymatize specifically because of the cereal license flavors, Elite Whey doesn’t carry them. For buyers who want the brand name and quality at a lower price and are happy with Chocolate, Vanilla, or Cookies & Cream, it works. For everyone else, the flavor premium for ISO100 is likely worth it.

Dymatize ISO100 Clear

20g protein in a clear, juice-style format

The Data

The Pro Tip

ISO100 Clear competes directly with Myprotein Clear Whey Isolate in the clear whey category. It has the advantage of Dymatize’s hydrolyzed isolate base, which may absorb faster — but Myprotein’s version has a wider flavor range and is typically cheaper. If you specifically want hydrolyzed protein in a clear format, ISO100 Clear is the only mainstream option.

The Honest Critique

Very limited flavor range at launch. Currently one flavor (Pineapple Passion Punch). The clear whey category benefits most from flavor variety — if you don’t like the single available option, there’s nowhere to go within this product line. Check the current product page for any flavor additions since this review.

Buyer’s Guide: Is Dymatize Right for You?

1. ISO100 is the right call if fast absorption matters or you want the best flavor range in the category. Post-workout hydrolyzed isolate will absorb faster than concentrate — relevant for competitive athletes. For everyone else, the cereal license flavors are the strongest reason to choose ISO100 over alternatives at similar prices.

2. Check whether you’re paying for hydrolysis you don’t need. ISO100’s price premium over Elite Whey and over competitors like Isopure Zero Carb comes from the hydrolyzation process. If you’re a recreational gym-goer with no digestive issues, the practical absorption difference won’t be measurable in your results. Run the cost-per-gram comparison and decide accordingly.

3. For maximum flavor variety across the whole protein powder market, compare against Myprotein. Dymatize wins on flavor creativity (licensed brands, Dunkin’ collabs); Myprotein wins on flavor volume (50+ options). See our best protein powder guide for the full comparison.

FAQ

What is Dymatize ISO100?

ISO100 is Dymatize’s flagship protein powder — hydrolyzed whey protein isolate, 25g protein, ≤120 calories, ≤1g sugar per serving. “Hydrolyzed” means the protein is pre-digested into smaller peptides for faster absorption. Banned substance tested.

Is Dymatize ISO100 third-party tested?

Yes — banned substance tested. See our safety testing guide for what this certification covers and how it compares to Informed Choice and NSF Certified for Sport.

What is hydrolyzed whey protein?

Whey protein that has been partially pre-digested using enzymes, producing smaller peptide chains that absorb faster than standard isolate or concentrate. Most relevant for athletes with multiple daily training sessions or digestive sensitivity to whole proteins. The practical benefit for recreational users is modest.

What are the best ISO100 flavors?

Fruity Pebbles, Cocoa Pebbles, and Cinnamon Cereal are the most-discussed flavors in the line. Gourmet Chocolate and Gourmet Vanilla are the best standard options. The Dunkin’ collaboration flavors (Glazed Donut, Mocha Latte) are well-reviewed for coffee-flavored protein.

How does ISO100 compare to Optimum Nutrition Gold Standard?

ISO100: 25g protein, hydrolyzed isolate, faster absorption, 13+ flavors, banned substance tested. ON Gold Standard: 24g protein, isolate-primary blend (not hydrolyzed), 20+ flavors, Informed Choice certified. ISO100 absorbs faster; Gold Standard has more flavor variety and a longer market track record. Both are strong products. See our best protein powder guide for the full comparison.

What is the difference between ISO100 and Elite 100% Whey?

ISO100 uses hydrolyzed whey isolate only — faster absorption, higher cost, 13+ flavors. Elite 100% Whey uses an isolate/concentrate blend — slower absorption, lower cost per gram, 3 flavors. Choose ISO100 for absorption speed or flavor variety; choose Elite Whey for cost efficiency.
