How to read a Whey Protein label
The panel lists both grams of protein per scoop and the scoop weight. Divide the first by the second to see how much of the scoop is protein: a 30 g scoop with 25 g of protein is 83% protein, a 40 g scoop with 24 g is 60%. The rest is carbohydrate, fat, flavoring and sweetener.
Compare price per gram of protein, not per scoop or per tub. Scoop sizes differ between brands, so "servings per container" can hide a large difference in how much protein you actually buy.
Isolate is whey filtered further than concentrate to remove more lactose and fat, so it usually carries more protein per gram and costs more per tub. Check whether the price gap survives once both are divided per gram of protein.
The FDA Daily Value for protein is 50 g, so a 25 g scoop is half of it.
Figures are from the FDA and the cited sources, listed under References below. Label guidance, not medical advice.
