Protein isolate is pure protein (protein content in the total mass of at least 95%). It is almost completely free from carbohydrates, fats and lactose.
Whey protein isolate is considered the best. It is made from whey, which is separated in the production of cheese. After that, using special technology, whey protein is released.
Protein isolate can be distinguished from a wide variety of products, such as fish, meat, cottage cheese, chicken, eggs. All of these foods are high in protein. But of course, none of them can be compared with whey protein in biological value and quality. It contains a huge amount of BCAA amino acids, which are needed for the synthesis of muscle tissue and for its restoration.
If you do not know which protein to choose and which one is the highest quality, you should pay attention to the composition of the mixture (it should not include various impurities and additives). The label on the package must not be damaged.
Today, in addition to protein isolate, there are other types of whey protein:
- Whey protein concentrate. This species is far from the purest type of protein, since the total proportion of protein in such mixtures is from 35 to 80%. Therefore, they can contain a large amount of fat and lactose.
- Whey protein hydrolyzate. During the production of this mixture, protein molecules are divided into tiny fragments, which allows them to be absorbed much easier and faster in the body. You can evaluate the quality of this protein according to its taste: if there is not enough protein in the mixture, it starts to slightly bitter.
Whey Protein Benefits
One of the main advantages of protein is the production of protein in the required amounts for muscle growth. Bioactive peptides that are found in whey protein have unique properties: they stabilize the immune system, inhibit the action of many microbes, lower blood pressure and improve digestion.
In addition, this protein contains glutamine - an amino acid that is necessary for the immune system (used by the body as an energy source). And the immunoglobulins that are part of the serum will help stop the weakening of the immune system. Whey protein also increases the level of glutathione, which is the most important antioxidant.
How to drink protein
There are many ways to take protein. Some people take it immediately after waking up, others before training, and the third after it. It all depends on the characteristics of a particular organism.
Protein intake time:
- After sleep. Basically, people sleep about 8 hours a day, and at this time the body does not receive food, so it begins to actively absorb the internal reserves of nutrients. The internal processes of catabolism are launched, and the best way to stop them is to drink a portion of protein. In about 30 minutes, the amino acid level will reach its maximum composition, and after that you can start breakfast.
- During the whole day. Between meals, you must take a protein isolate. If you are trying to lose weight, you can replace meals with protein foods. And protein mixtures are ideal for people who want to build muscle.
- Before training. A protein isolate should be taken about 2 hours before training, this will help to avoid catabolism and provide the body with the necessary amino acids.
- After workout. It is after physical exertion that the body absorbs almost all nutrients well, so taking protein will ensure the supply of amino acids in the shortest possible time, and carbohydrates will restore glycogen levels in the body.
