Weight
The weight of the protein supplied in this packaging option (excluding packaging).
Knowing the amount of protein and the size of the daily portion, you can estimate how long this amount will last. And since different situations require a different supply of product, the same brand is often produced in several weight options. At the same time, larger packages, usually, are cheaper in terms of a kilogram of weight. However, it cannot be said unequivocally that it always makes sense to buy large volumes — for example, it is convenient to take a small package “for testing”, at the end of a training programme or for the duration of a trip if the main stock is left at home.
Note that many manufacturers traditionally tie the weight of their products to pounds: for example, the weight of 4.54 kg, popular among large cans and packages, corresponds to just 10 pounds.
Protein amount per serving
The amount of pure protein in each serving of protein.
Not a single protein (as a type of sports nutrition) can consist of 100% protein — even the purest products inevitably contain aromatic and flavoring additives, preservatives and other "service" substances. Therefore, the amount of protein itself will inevitably be less than the total weight of the serving. And this amount needs to be known for accurate calculations that provide the right diet. In addition, knowing the ratio between the weight of the protein in the serving and the weight of the serving itself, it is possible to assess the degree of purification and the overall quality of the concentrate (see "Type").
Calorie portion
Calorie content per serving of protein (see "Serving").
Correct determination of the optimal number of calories and compliance with these requirements is an integral part of a complete sports nutrition. Accordingly, specialized sports nutrition, including proteins, necessarily contains information on calorie content. In general, higher calorie brands are useful mainly for weight gain, lower calorie brands for fat burning, although in fact a lot depends on the characteristics of the athlete and his training programme.
