Buying Guide: What to Look for in a Whey Isolate
Protein Purity and Amino Acid Profile
Not all isolates are created equal. A true isolate like Dymatize ISO100 undergoes cross-flow microfiltration to remove excess lactose, fat, and carbs, leaving behind a product that is over 90% protein by weight. Legion Whey Plus also uses cold-process filtration but includes added digestive enzymes. When you compare labels, look for the BCAA count and the ratio of disaccharides to protein. Both deliver around 5 grams of BCAAs per serving, but Dymatize guarantees a minimal 1 gram of sugar per scoop, which is ideal for those watching their insulin response.

Digestibility and Gut Comfort
Many whey isolates cause bloating because of residual lactose or harsh processing. Dymatize ISO100 is hydrolyzed, meaning the protein chains are broken into smaller peptides for faster absorption and less gas. Legion Whey Plus adds a proprietary enzyme blend (including lactase and proteases) to aid digestion. If you have a sensitive stomach, both are good options, but the Dymatize hydrolyzed formula is often easier on the gut immediately after a workout.
We also compared similar digestibility features in optimum nutrition vs MuscleTech protein if you want to see how other brands handle this.
Taste and Mixability
Flavor is subjective, but Dymatize ISO100 has built a loyal following for its rich chocolate and vanilla flavors, especially the Cocoa Pebbles variant that tastes like your favorite childhood cereal. Legion Whey Plus uses natural flavors and stevia, which some find slightly bitter. Both mix easily in a shaker with no clumps. If you prefer a dessert-like experience without artificial aftertaste, Dymatize ISO100 stands out.

Ingredient Transparency and Third-Party Verification
Both Dymatize and Legion pride themselves on clean labels. Dymatize ISO100 is gluten-free, uses no banned substances, and is made in the USA. Legion publishes every ingredient and its purpose. However, Dymatize has the advantage of being informed-sport certified for some batches (though not all variants). If you are an athlete who undergoes drug screening, look for ISO100 with the certified seal. For everyday use, both are trustworthy.
