Comparing protein powder

We count the protein a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Protein powder comes as whey concentrate, whey isolate, whey hydrolysate, whey blend, milk protein, casein, beef protein, egg white protein, soy protein, pea protein, rice protein and vegan protein blend, and each form has its own table, because someone buying one would not usually take another as a like-for-like substitute. Products that combine protein powder with other ingredients are listed separately, because their price buys more than protein. 25 g is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Prices last checked: 20 October 2026. Ranked purely by price per 25 g protein — a comparison unit, not a recommendation. We earn commission when you buy through these links; it never affects the order.
