Our verdicts
20g Plant Protein Shake
OWYN is a clean, allergen-friendly vegan shake that avoids artificial sweeteners and is well liked for its smooth texture. But its plant protein scores lower on quality than dairy, it adds 4 g of cane sugar, and at 180 calories with little vitamin or mineral content it is a snack rather than a meal. Choose it for dietary restrictions rather than for value.

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.
