Optimum Nutrition Gold Standard 100% Casein 1.82kg vs Dymatize ISO100 Hydrolyzed Whey Protein Isolate 2.2kg
Optimum Nutrition Gold Standard 100% Casein 1.82kg: ON Gold Standard Casein delivers what it promises — a slow-digesting micellar casein that provides sustained protein delivery, typically used before bed. The thick, pudding-like texture is a standout feature that many consumers enjoy as a high-protein dessert. At 24g protein per serving with a solid amino acid profile, it matches ON's whey for nutritional quality. However, the ingredient list is notably more complex than their whey product, with four different thickeners including carrageenan. Whether casein before bed provides meaningful benefits beyond simply meeting daily protein targets remains scientifically debated.

Dymatize ISO100 Hydrolyzed Whey Protein Isolate 2.2kg: Dymatize ISO100 is a premium hydrolyzed whey isolate that excels in protein purity, taste, and digestibility. With 25g protein, under 1g sugar, and under 1g fat per serving, it is one of the leanest options available. The hydrolysis process provides faster absorption, which may benefit post-workout recovery though the real-world advantage over standard isolate is debated. The taste, particularly Gourmet Chocolate, is widely considered best-in-class. The significant drawback is the price — roughly double that of budget whey concentrates — making it hard to justify unless you specifically need a lactose-free isolate.
