Whey protein isolate: what it is, what it consists of, features
It is becoming more common than any amateur training has some kind of nutritional supplement, either for your health or to improve physically, both body composition and muscle recovery. Today we will talk about one of the most famous, and surely all have heard: Whey Protein Isolate

Whey, the supplement sold and consumed more
Surely, today, whey protein is the best-selling supplement (next to the Creatine) both inside and outside the world of sports nutrition. Part of his fame is due to the benefits shown in some clinical trials or even at the level of body composition.
Protein Not Just for Athletes
Although WHEY protein intake is associated with athletes, there have been some benefits that can be extrapolated to clinical nutrition or even the daily life of a person who only does sport as a hobby. When looking at the properties of this protein, we realize that despite being insulinotropic (releases large amounts of insulin), long term improves sensitivity to the hormone by the tissue, which translates as a reduced need for insulin.
This effect of WHEY protein or BCAAs containing not only acts at the level of insulin, but also improves glucose sensitivity, having an anti diabetic effect.
Comparison of Protein
The first thing to look at a protein supplement is its nutritional value. Obviously, we are concerned that their protein intake is high, something that many protein supplements met without difficulty.
As can be seen, most supplements have a higher protein intake to 70% (except for the AF mark WHEY). However, the amount of protein does not ensure a product is of quality as this marks largely the greater or lesser presence of certain amino acids (aminogram). The graph discussed below, see the amount of BCAAs (essential branched amino acids) containing each protein.
A while ago we decided to clarify the user the subject of comparative protein among brands, because often suggests some controversy. The end customer must be shown the utmost transparency, an obvious fact if this same person also choose to compare the wide range of proteins to decide which one to choose. Sometimes companies are governed by certain parameters which are not 100% objective and do not specify values according to reliable information. To leave no doubt, in this article we have solved the dilemma of how to compare proteins, throwing some light on a topic somewhat gloomy, and according to the criteria that a regular consumer should keep in mind.
Comparison of BCAAs
For the EVOLATE, which is a protein Whey Protein Isolate, the contribution of BCAAs is close to 20g, being superior to other known proteins. This would explain how to compare Whey Protein Isolate with other vegetable protein (Soy Protein Isolate) or other WHEY in concentrate form, ISO wins for quality concerns.
However, one reason why the protein WHEY ISOLATE creates some rejection in the world of supplementation, is its high cost compared to other hyper protein formula.
As you can see in the chart above, most of WPI (Whey Protein Isolate) in 2 kg formats, over $90, however, EVOLATE has a lower price than others despite having the same raw material products AMIX (reflected in the graph as red bars)
The way of obtaining such a product is by CFM (Cross-Flow Micro filtration), which keeps substances of great interest that are lost with other forms of purification, such as by ion exchange. The latter and as the name suggests, uses substances to exchange ions and thus purify the protein from milk (WHEY). However, when using substances of an acid pH causes said fractions can provide certain benefits are lost.
Lecithin Evolate of HSN Sports incorporates this type of material of the first global quality: use an isolated serum high quality used as emulsifier sunflower lecithin instead of using most “soya lecithin” in order to eliminate allergen and without sacrificing the characteristic product quality.
Composition CFM Whey Isolate
The a-lactalbumin is a protein found mainly in human milk, but has also been observed, to a lesser extent, in cow`s milk. As it is no wonder, lactalbumin makes breast milk in a non-substitutable contribution for newborns because it provides other benefits such as protection against pathogenic bacteria.
This protein serves to provide essential amino acids, such as tryptophan, serotonin precursor and helps maintain adequate levels of melatonin (hormone related sleep-wake cycle). This fact suggests as high protein WHEY lactalbumin can improve cognitive performance in some groups susceptible to stress persons.
Protein in milk is believed that can help the transport of substances of lipidic origin, although its evidence is not entirely clear.
Glycoprotein (protein which has an attached carbohydrate) that helps the absorption of iron and having bacteriostatic activity (limits growth of certain groups of bacteria) so that associated one better immune status. Not to forget, that poor intestinal flora is associated with obesity problems, where accompanied to greater absorption of glucose by these people increases the likelihood of diabetes.
As its name, we speak of a peptide derived from casein containing sugars in their structure. Its properties are as follows:
- Reduction of gastric secretion
- anti-cariogenic effect (prevents caries)
- Inhibits cholera toxin
- Modulates the immune response
- Prevents intestinal infection
- It is associated with less hunger
One of the most important protein in the Isolate, because helps the immune system fight invading microorganisms. This potential made the food industry questioned used to preserve certain foods, however, their high cost prevents such application.
As we can see, the WHEY ISOLATE obtained through CFM results in a WHEY protein bio active substances that help our bodies and especially to improve our immune system.
Whey Protein Isolate and Sportsmen
However, when we talk about its impact on the athlete, the result obtained is also satisfactory, especially when we talk about post-workout recovery. One of the factors most neglected by athletes, is the hydration:
With just one 4% dehydration, we reduced our performance by increasing cardiac stress level and especially neuromuscular level,
increasing fatigue almost 12%. This problem hydration will impact heavily on athletes who perform strength training, as dehydration is one of the most common reasons why injuries occur in tendons and joints
Not surprisingly, the protein ISOLATE provides benefits on hydration because as seen in previous studies, milk is a drink that hydrates equal to or more than the commercial beverages. In my opinion, this may be due to consumption of whey protein post-workout raises levels of albumin, a protein found in plasma and helps maintain cellular hydration thanks to its effect on oncotic pressure.
How can we make the most of the WHEY PROTEIN ISOLATE?
As many know, there are a lot of supplements that have synergistic effects, or in other words, it enhances the effect of one or both supplements. In the case of ISOLATE, it will not be different.
Protein and Creatine
When we look studies such protein accompanied by creatine and its effects at body composition against carbohydrates gives the following results:
As we can see, the group that combined WHEY ISOLATE and CREATINE, raised an amount of greater weight than the group that consumed carbohydrate alone, thanks largely to higher levels of creatine.
Whey Protein Isolate to Recover
While it is true that a high carbohydrate intake accompanied creatine can lead to greater gains in fat – free weight compared to Whey Protein Isolate + Creatine, this is partly due to muscle glycogen, not greater muscle mass. This theory I pose, I arise from the scientific evidence, showing how carbohydrates have a worse potential muscle recovery compared to a high quality protein, as ISOLATE.
In conclusion, we can see how the Evolate protein (Whey Protein Isolate) provides benefits beyond a high intake of protein, making it one of the star products both sporting level, as well as health level.
