Number of servings
The number of servings contained in this packaging option. For more on the meaning of the term "portion", see the relevant paragraph below; here we only note that the recommended serving size may differ from that indicated by the manufacturer, respectively, and the actual number of servings may be less or more than the claimed one. Nevertheless, according to this indicator, one can at least approximately estimate how long the package will last. The most modest packaging options include
up to 25 servings, in the largest this number can
exceed 100.
Serving
The size (weight) of a standard serving of protein; most often we mean a portion for one dose (there may be several such receptions per day). This indicator is indicated depending on the packaging features: for example, for products in individual packaging (bags), the weight of the contents in one bag is given.
Anyway, note that in the characteristics the manufacturer indicates a certain conditional portion, designed for a “standard” athlete and an average level of loads. In fact, the optimal serving size may differ markedly from the standard one depending on weight, metabolic characteristics, training programme, dietary specifics, etc. Detailed recommendations for such calculations can be found in special sources, but anyway, these calculations are based on the size of a standard servings claimed by the manufacturer.
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.
