The diet supplements market offers us a huge number of types of supplements. The case is no different in the case of protein. Which type to choose? The most common types of proteins are listed below.
- Whey protein hydrolyzate
- Whey protein isolate
- Protein concentrate
- Casein protein
- Soy protein
- Egg protein
- MIX of proteins
Whey protein hydrolyzate
It is the most advanced protein product on the supplement market. It has in its composition a full-blown protein with a very fast rate of digestion and absorption in the body. It is great as a dietary ingredient for athletes.
The disadvantage of this type of preparation is that it can negatively affect the level of insulin in the blood. Sometimes it increases its content by more than 40%!
Whey protein isolate
The content of pure protein in the whey protein isolate can be up to 95%! In addition, it has a very high rate of digestion and absorption of BV = 159. For comparison egg proteins BV = 100 and casein protein BV = 77.
Therefore, the whey protein isolate is ideal as a preparation used right after weight training!
It is the most commonly used protein supplement. Although it is slightly more expensive than protein concentrate, functionalism speaks for it.
The protein concentrate contains from 70% to 85% pure protein. At the same time, it is absorbed more slowly by the body than the whey protein isolate. One of the best sources of milk protein. It is also characterized by a high anti-catabolic effect and optimal proportions between the exo and endogenous amino acids.
A relatively low price also speaks in his favor.
Casein is a milk protein constituting 75% of the composition of milk proteins. Due to the long time of digestion and absorption it is great for the protein used before bedtime. Thanks to this, it will have anti-catabolic action.
However, it is not recommended for people who are allergic to lactose, one of the components of milk and dairy products.
Soy is the only plant that provides a complete chain of exogenous amino acids, that is, those that the body is unable to produce itself and should be obtained along with food.
Soy protein is characterized by a low degree of time of digestion and absorption. That’s why they are a great alternative for those who are allergic to egg white, animal meat or lactose. It is worth noting, however, that too high supply of soy may manifest itself as side effects in the form of hormonal disorders. It is often consumed as an ingredient in many dishes, so you can even unconsciously deliver very large amounts of soy proteins to the body.
Despite the fact that the egg protein is a protein of standards and shows the fastest digestion and absorption rate among food products – egg protein loses in this respect with many protein supplements, including with a popular and often used whey protein isolate. The advantage of egg white is that it is additionally enriched with vitamins and minerals.
Due to the relatively long time of digestion and getting into the cells of the body it is ideal as an addition to meals during the day or for use before bedtime.
MIX of proteins
In addition, it should be mentioned that there are all kinds of MIX protein supplements combining different types of protein or enriched with additional formulations, e.g. carbohydrates. These nutrients are great for supplementing all the necessary ingredients in the athlete’s diet, however, the high price speaks to their disadvantage.
