Optimum Nutrition Gold Standard 100% Whey Protein 2.27kg vs Dymatize ISO100 Hydrolyzed Whey Protein Isolate 2.2kg

Optimum Nutrition Gold Standard 100% Whey Protein 2.27kg: Optimum Nutrition Gold Standard Whey remains one of the most trusted and consistently well-reviewed protein powders on the market. The whey isolate-primary blend ensures a high protein-to-calorie ratio with solid amino acid profile including 5.5g BCAAs per serving. Mixability and taste are frequently praised across thousands of reviews. The main drawback is the premium price point, which has increased notably in the UK market over recent years. It suits those who prioritise reliability and quality over cost savings.

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.
