The 10 best (and worst) whey protein powders - taste-tested

With whey protein prices rising as much as fivefold, The Guardian’s test team set out to find which powders are worth the cost. The article notes that “proteinmaxxing” has spread alongside GLP-1 weight-loss drugs, which can reduce overall food intake, increasing demand for protein. Ten whey powders were evaluated first through blind taste tests at the Guardian’s New York office using blender bottles with water, then narrowed to five finalists for additional home testing using milk instead. The study looked at ingredients and third-party certifications including NSF, Informed Sport, Informed Choice, or GMP, and excluded some brands with longer additive lists despite strong taste reputations.
