Serving size is the amount of a product that the label's nutrition numbers describe, such as one 30 g scoop. It is not a recommendation.

**How we rank:** Serving size matters for comparisons. Two products may both claim 25 g of protein, but if one needs a 31 g scoop and the other a 40 g scoop, the second contains more non-protein ingredients. Divide protein grams by the serving weight to get protein density, and use servings per container to calculate cost per 25 g of protein. If you use two scoops, double every number on the label.
