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.

All-In-One Nutrition Shake
Ka'Chava is one of the best-tasting plant-based meal shakes, with good protein, fiber and vitamin coverage per serving. But you are paying a premium for a long superfood list whose doses are undisclosed, and 240 calories is light for a meal. Huel Black Edition delivers more protein and calories per dollar; choose Ka'Chava if flavor is what keeps you consistent.
