From Milk to Muscle – the Whey Story!

Author: Nicole Adler   Date Posted: 1 September 2016 

Whey protein is known by athletes across the globe, but what makes whey protein so effective? To learn about whey protein concentrate, isolate and all the other whey proteins on the market today, please read the information provided below.

What Are the Life Essential Nutrients Inside Whey Protein Concentrate?

One of the reasons why Whey Protein Concentrate  can do so many good things for the human body is the large number of essential nutrients, more specifically macronutrients. Inside whey protein concentrate, there are carbohydrates, lipids and proteins, which can all contribute to a healthier and fitter body if used in combination with the right exercise routine. 

Protein stands out considerably from the other macronutrients inside whey protein concentrate, because protein consists of nitrogen chains. These nitrogen chains also contain subunits, which are referred to as amino acids. These amino acids are literally the building blocks of the human body, so having a supplement that can provide these substances can make a hell of a difference where fitness is concerned.

There are 22 amino acids in total and only eight of them cannot be made by the human body. Instead, these amino acids have to be obtained from foods. To distinguish these amino acids from other amino acids that can be made by the human body, nutritionists refer to them as essential amino acids. 

In addition to the eight that cannot be made by the human body, there are another seven conditionally essential amino acids or CEAAS. These conditionally essential amino acids can be made by the human body, but once the body comes under a severe amount of emotional or physical strain, the body cannot make enough of them. Therefore, dietary sources need to be relied upon. 

At the end of the day, whey protein is a complete protein; this means that it contains all the essential amino acids that cannot be made by the body. Of course, whey protein also contains the other amino acids that are needed for a healthy lifestyle.

How Is a Whey Protein Supplement Made?

Whey is a source of protein that can be found in milk, aside from casein, another protein that is used in supplements. To be able to make a supplement from whey protein, manufacturers have to separate the whey from the curd during the cheese making process. As soon as it is obtained, whey contains approximately 92% water, 6.5% lactose, 0.9% protein and 0.2% vitamins, minerals and fat-soluble nutrients, so whey protein is not perfect from the moment it is obtained.

When you buy a whey protein supplement, it will have between 65% and 80% protein. In order to get there, manufacturers have to subject whey to processing, so the right percentages of the protein can be obtained. Due to the various processes whey protein goes through, there are three primary forms of protein: concentrate, isolate and hydrolysed whey. 

To create whey protein concentrate from whey protein, the crude whey has to go through a process known as ultrafiltration. During this process, the crude whey is diminished to 20% of its original volume. Then, the whey goes through another filtering process under a low temperature; this process will remove excess quantities of fat, lactose and cholesterol. After this process, the whey is carefully dried.

Other processing methods can make a different form of whey as well, for example hydrolysed whey or hydrolysed whey peptides. Thanks to unique processing methods, hydrolysed whey has obtained a higher bioavailability than whey protein concentrate, and is therefore also one of the more popular forms of the supplement.

How Do I Recognise Good Quality Whey?

With numerous whey protein supplements on the market today, it can be a little hard to find the right one, especially if you have no experience whatsoever with supplements. However, one thing that always needs to be remembered is that quality is the number one priority if you want to get good results. Quality will be based on denominators such as biological value, protein efficiency ratio and protein digestibility corrected amino acid score. 

When you shop around for a high quality protein supplement, do not forget that there is no “perfect” whey protein supplement on the market, but some are more effective for your metabolism and training purposes than others. 

Why Should I Buy Whey from Nutrients Direct?

Nutrients Direct has a large range of quality whey protein supplements in its range. Of course, you do not have to take our word for it, because the nutritional information of each supplement is clearly displayed on the product description pages.

At Nutrients Direct, customers can currently obtain the three main forms of whey protein: whey protein concentrate, whey protein isolate and hydrolysed whey. For athletes on a tight budget, we recommend whey protein concentrate. Even though it contains less protein than our whey protein isolate, the supplement can still give you the results you want despite being on a tight budget. If you do not like spending a little more, then you can always go for whey protein isolate.

Naturally, there are some athletes who seem to be struggling with digestive discomfort every time they use a supplement; this can be due to a sensitive digestive system, but also due to general problems with digestion. If this is a problem for you, we can highly recommend hydrolysed whey protein isolate. Hydrolysed whey protein isolate is considerably easier to digest than any other form of whey, simply because the supplement has been processed further into smaller particles. 

In addition to whey protein supplements, athletes can also come to Nutrients Direct for vegetable-based protein supplements. If you are a vegetarian, then we can recommend having a look at our pea protein, rice protein and soy protein supplements. Similar to whey and casein, these vegetable-based proteins each have their unique properties and benefits, so be sure to read through them all to find the best vegetable-based protein supplement for your vegetarian lifestyle.
