Whey protein isolate is the type of whey protein found in most supplements. When choosing a whey protein supplement, look for products that list either whey protein isolate or whey protein concentrate as the first or second ingredient on the label to ensure that you're getting an adequate amount of whey protein.
Keep reading if you see these terms on the label of a protein supplement: Protein blend, hydrolyzed protein or milk protein isolate. These may be fine as protein products, but if whey is what you want, be sure that the label says so.
Next, check the nutrition facts box on the protein product label to see how many grams are in a serving size and how many grams of protein are in a serving. For example, if a serving of whey protein A is 29 grams and each serving has 21 grams of protein, and a serving of whey protein B is 42 grams with 14 grams of protein, whey protein A is more concentrated. That doesn't mean that one is “better” than the other; they are just different and you can choose the type of whey protein that suits your needs.
In general, the recommended daily protein intake for healthy adults is 0.4 grams per pound of body weight. So if you weigh 150 pounds, you need about 60 grams of protein, and if you are a frequent exerciser, you may need more.
