Our verdicts
Core Power High Protein Milk Shake
Core Power is one of the best-tasting ways to get 26 g of real milk protein with no added sugar and no lactose. It is a recovery shake rather than a meal, so treat it as a protein boost alongside food, or choose the 42 g Elite if you want something more filling. Expect to pay roughly double Premier Protein's price per gram of protein.

30g High Protein Shake
Premier Protein is one of the cheapest and best-liked ways to add 30 g of protein to your day. As a meal replacement it falls short, since 160 calories with almost no carbohydrate, fat or fiber is a snack rather than a meal, so pair it with real food. The lack of third-party certification and co-manufacturer recalls in 2022 and 2023 keep its quality score in check.
