Author: Nicole Adler   Date Posted: 10 November 2016 

Have you just started a training program and do you need a little boost when it comes to muscle repair and muscle growth? Then a whey protein powder from our range of Australian online supplements may be just what you need. Below, you will find important information about whey protein powder in our Australian online supplements range, so you can make an informed decision!

What Is Whey Protein?

Whey protein powder in our Australian online supplements range can be described as a mixture of proteins. These proteins are obtained from a substance called whey, a by-product of the cheese making process.

When you look at the proteins inside milk, you will find two different types: whey and casein. However, these proteins are not present in the same levels, because milk mainly consists of casein (80%). The remaining 20% of protein in milk is considered as whey.

So why not drink a lot of milk to obtain more whey protein in your diet? Well, the concentrations of casein and whey in milk are a lot lower than the concentrations in our Australian online supplements. To get higher concentrations, whey and casein need to be subjected to specific filtering processes, which enables us to deliver protein powders with an incredible amount of whey or casein protein in our Australian online supplements range.

Should I Look at Nutritional Information Before Purchasing a Whey Protein Powder?

Athletes should always look at the nutritional information of whey protein before they make a purchase. Whey protein as a raw product does not have a pleasant taste, which is why most powders have been flavoured. While many supplement manufacturer will use natural flavourings that do not affect the healthy nature of the shake, there are some manufacturers that add unhealthy additives to make their shake taste better; this includes refined sugars. Therefore, always check the protein shake thoroughly for any unwanted additives before you buy them.

What Is Whey Protein Used For?

Whey protein can be used for various fitness purposes, because protein and branched chain amino acids inside the shake can provide athletes with quite some benefits. The protein is a versatile nutrient, which is used for numerous biological and chemical functions in our bodies, so without protein, our body would not be able to function correctly.

Proteins are the building blocks of the human body, since they are used for our tendons, organs, skin, hormones, enzymes, neurotransmitters and more. However, many people do not know that protein consists of smaller molecules called amino acids. Some of these amino acids can be produced by our own body, but there are some amino acids that need to be obtained from food, since they cannot be made by us.

When you want a protein supplement that contains all the amino acids you need for better sports performance, health or even muscle building, you need to be looking for a protein powder that is described as a complete protein. A complete protein contains all the essential amino acids, which are the substances our body cannot produce by itself. However, these amino acids are needed for muscle building, muscle repair, muscle maintenance and even weight loss.

Whey protein also contains branched chain amino acids. These are amino acids such as leucine, isoleucine and valine. Whey protein also contains plenty of cysteine, a substance that boosts the production of one specific antioxidant called Glutathione.

What Are the Different Types of Whey Protein?

In general, there are three large groups of whey protein; this includes whey protein concentrate, isolate and hydrolysate. Whey concentrate may contain anything between 70 and 80% protein, but also traces of lactose and fat. Compared to other shakes, whey concentrate is considered as the tastiest.

Whey protein isolate does have its benefits as well. The protein supplement can contain up to 90% of protein and contains less lactose and fat compared to whey protein concentrate. However, filtering concentrate further does mean that isolate has less additional nutrients than whey protein concentrate.

Hydrolysed whey is the last type of protein powder and is commonly used for its easy digestion abilities. The proteins inside hydrolysed whey have been pre-digested, which means athletes can count on a quick absorption of the protein inside. However, hydrolysed whey can cause an insulin spike that is 28-43% greater than in whey protein isolate.

What Is the Impact of Whey Protein on Muscle Growth and Muscle Repair?

One of the main reasons why athletes will start taking protein supplements is the improvement of their muscle building and muscle repair abilities. In these cases, whey protein is an excellent choice, because the proteins inside have numerous positive effects on the body.

Firstly, the protein inside whey protein provides athletes with both protein and amino acids. These substances are used as building blocks by your muscles, subsequently promoting muscle growth and increasing the chances of getting more results from your rigorous workouts.

Whey protein can also influence hormone production. Once consumed, whey protein can increase the release of certain anabolic hormones. These hormones can stimulate muscle growth, which is extremely beneficial for athletes with stunted muscle growth.

A whey protein shake will also contain leucine, an amino acid that is extremely important for muscle protein synthesis; this both on a molecular and a genetic level. In addition to that, whey protein is absorbed extremely fast compared to other protein supplements, which means athletes will get quick access to the nutrients they need for muscle growth and muscle repair.


Whey protein is a useful supplement for both beginning and experienced athletes. However, if you are just starting out with supplements, it is recommended to do a little research regarding recommended dose and the best time to take your supplement. Of course, this process can be made easier with the help of an experienced personal trainer or nutritionist. Therefore, if you intend to use supplements to increase your results, be sure to ask some assistance from a health professional.
