Comparison Myprotein Impact Whey Protein 2.5 kg vs BioTech Hydro Whey Zero 1.8 kg

— Concentrate. Historically, the first type of protein as a sports nutrition, obtained in the simplest way. For example, whey (see "View") concentrate is made by filtering whey through a membrane with microscopic holes that let fat and lactose molecules through, but retain protein. This technology is inexpensive, which accordingly affects the cost of the product. However, the filters, to put it mildly, are not perfect, and the quality of the protein concentrate is very low — for example, in the same whey product, the protein content can vary from 35% to 85%, and the amount of fat and lactose is very high. However, high-quality sports concentrates with a protein content of 80% or more may not be inferior in their properties to isolates (unless with increased sensitivity to lactose, whey concentrates should be used with caution).

— Isolate. A protein obtained using more advanced filtration technologies than the concentrate described above. It is a good compromise between availability and quality: the protein content in pure isolates is 95% or more, and such products are relatively inexpensive and quite affordable for most ordinary athletes.

— Hydrolyzate. The hydrolyzate is the most advanced and high quality protein in terms of production technology. During the production process, protein molecules are not only filtered out with a high degree of purity,...but also split into separate fragments — similar to how it occurs at the initial stage of digestion in the human body. Thus, the athlete receives the most ready-to-use protein, and the hydrolyzate is absorbed very quickly and with a minimum of energy expenditure. On the other hand, such products are expensive; and in relatively inexpensive varieties, it often happens that only a part of the protein molecules turns out to be split (hydrolyzed) (sometimes less than half of the total).

— Complex. A product with a combined composition containing proteins with different digestion rates — both “fast”, replenishing the deficiency of amino acids after training, and “slow”, replacing (fully or partially) regular food and/or working as nightly compensators for muscle catabolism (see. p. "Night" below). It is believed that this option is well suited for those who want to lose weight through training, as well as for those who generally lead an active lifestyle, not limited to exercising in the gym.

— Night (long). Proteins with a low absorption rate, digestible for a long time. One use for these products is to prevent nocturnal muscle catabolism (the breakdown of cells during sleep), hence the name. However, the matter is not limited to this — "long" proteins can be consumed during the day. For example, they can be useful for maintaining a feeling of fullness and reducing the need for regular food, which is very useful when working on weight loss; in addition, a long-term uniform intake of protein in the body will be convenient for those who lead an active lifestyle — to protect against exhaustion. "Long" are only products based on casein (see "View")

— Albumin. Protein based on a specific protein found mainly in eggs (see "Type"), as well as in blood serum. Albumin is considered to be an almost "perfect protein", it has the maximum content of essential acids and the highest efficiency. Such a product, in particular, is great for weight loss programs, in addition, it helps to reduce blood cholesterol levels and increase hemoglobin levels. The rate of absorption of albumin is medium, which makes it quite versatile. On the other hand, this type of protein is relatively rare and, most often, very expensive.

The type of package in which the protein is supplied.

Proteins up to 4.54 kg (10 lb) can be supplied in boxes, cans or bags. The first option has not received much distribution, and the choice between the remaining two depends mainly on how often you have to carry the product with you. So, the package takes up less space (and decreases in volume as the contents are consumed), which makes it easier to pack it in a bag; the jar is more stable on the table, shelf, etc. Also note that it is usually easier to “climb” into the package with a spoon or hand, taking out the powder or tablet, respectively, and it is more convenient to pour out / shake out the contents from the jar.

With a product quantity of more than 4.54 kg, buckets are used exclusively, their capacity can reach 7 kg. Although the bucket usually has a carrying handle, it is still more convenient to keep it in one place, and collect the necessary portion of the protein for carrying “with you” in another container, smaller, for example, in a bottle or jar. Moreover, the large width of the bucket makes it easy to collect the contents — you can even lower the container directly inside.

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.

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.

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 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.

The country in which the protein was released. Quite close attention is often paid to this information: it is believed that products manufactured in highly developed countries like the USA or Germany are of the highest quality. However, this approach is largely incorrect, because different manufacturers can understand the term “country of production” in very different ways — to the point that it often means only the “homeland” of the brand, and the product is produced in completely different countries. This cannot be called an unambiguous deception: conscientious manufacturers usually carefully monitor the quality of their products and maintain the reputation of a “high-class American (German, etc.) brand” (especially since high-tech production, in compliance with the necessary standards, can now be deployed in any region) . On the other hand, coming from a less popular country does not in itself mean a less conscientious manufacturer. Therefore, in fact, the quality of the product is practically not related to the country of production, and it is worth paying attention to the reputation of a particular brand rather than its “origin”.
