Technical Discussion

Whey protein isolate (WPI) is extremely popular amongst athletes due to its ability to be digested very rapidly and beneficial in improving muscle recovery and protein synthesis. Due to the WPI method of filtration, whey isolates tend to be less allergenic than concentrates and other bovine milk or dairy products. WPI typically contains approximately 85-90 percent protein, much higher than whey proteins concentrates (WPC), as well as lower in lactose, carbohydrates and fats compared to WPC. For this reason, many individuals choose WPI over WPC so as to increase lean muscle mass and to effectively enhance muscle recovery. Furthermore, due to the very low content of lactose in WPI, it is highly suitable for individuals who are lactose intolerant. 


Manufacturing of Whey Protein Isolate

Similar to the manufacturing of Whey Protein Concentrate (WPC), Whey Protein Isolate (WPI) manufacturing process starts with pasteurised skim milk and held over night. The liquid whey (from the cheese making process) is then drained through a stainless steel screen. Whey liquid is then filtered. The liquid is filtered to one-fifth its original volume, resulting in whey concentrate that is approximately 80% protein, commonly known as WPC. 


In the production of WPI, the whey concentrates are further micro-filtered to increase protein concentration to as high as 90%. The final WPI is then spray-dried to achieve whey protein powder. VPA Australia WPI is processed via proprietary ultra-filtration techniques, generating un-denatured and highest quality soluble whey proteins. 


Health Benefits of VPA Australia Whey Protein Isolate 


Grass fed cattle from NZ

This product is regarded as the best whey protein product anywhere on the planet. Free from bovine growth serum  (legal in other parts of the world). 


No Fillers

We pride ourselves at VPA Australia Protein for only selling 100% pure products. You can be guaranteed that our VPA Australia WPI is pure WPI with a small amount of flavouring and sweetener. 


Low temperature processing ensures retention of both nutritional and functional properties.


Naturally high in the three essential amino acids (leucine, iso-leucine and valine) compared to other protein sources, with leucine being recognised as the trigger for muscle protein synthesis. 


Health Benefits of Whey Protein Isolate in general


Suitable for lactose intolerant individuals - WPI is very low in lactose.


Increase lean muscle mass

WPI is low in carbohydrates and fats along with high protein and amino acid content excellent in enhancing lean muscle mass. 


Reduce Muscle Loss & enhance recovery

Many years of research have shown supplementing milk proteins particularly, Whey Proteins, can reduce muscle loss due to the high content of L-Gluatamine (Walzem et al, 2002). Furthermore, the high content of L-Glutamine can also restore energy efficiently after an intense workout, thus improving recovery. 


Increase strength & muscle growth

Boire et al demonstrated that men engaged in resistance training programs while supplementing with whey proteins showed greater improvements in strength than men using resistance training alone. This is mainly due to the high Branched Chain Amino Acid (BCAA) content in whey protein. It has been found that the quality of a particular protein for enhancing muscle mass and strength is related to its Leucine content. 


Enhance protein synthesis

Whey proteins can contain up to 26% BCAA, which are efficient substances for synthesizing new proteins where BCAA Leucine acts as a signalling molecule for initiation of protein synthesis. 


Increase bioavailability of essential amino acids

Research found that the amino acid profile in individuals’ dietary proteins influences their nitrogen utilization. This means poor quality dietary protein intake have been shown to increase nitrogen losses and limit protein synthesis, therefore ingestion of whey proteins containing high essential amino acids can reduce nitrogen losses (Boire et al, 1997).

Furthermore, due to the very low content of lactose in WPI, it is highly suitable for individuals who are lactose intolerant. 


Manufacturing of Whey Protein Isolate

Similar to the manufacturing of Whey Protein Concentrate (WPC), Whey Protein Isolate (WPI) manufacturing process starts with pasteurised skim milk and held over night. The liquid whey (from the cheese making process) is then drained through a stainless steel screen. Whey liquid is then filtered. The liquid is filtered to one-fifth its original volume, resulting in whey concentrate that is approximately 80% protein, commonly known as WPC. 


In the production of WPI, the whey concentrates are further micro-filtered to increase protein concentration to as high as 90%. The final WPI is then spray-dried to achieve whey protein powder. VPA Australia WPI is processed via proprietary ultra-filtration techniques, generating un-denatured and highest quality soluble whey proteins.

Health Benefits of Whey Protein Isolate in general


Suitable for lactose intolerant individuals - WPI is very low in lactose.


Increase lean muscle mass

WPI is low in carbohydrates and fats along with high protein and amino acid content excellent in enhancing lean muscle mass. 


Reduce Muscle Loss & enhance recovery

Many years of research have shown supplementing milk proteins particularly, Whey Proteins can reduce muscle loss due to the high content of L-Gluatamine (Walzem et al, 2002). Furthermore, the high content of L-Glutamine can also restore energy efficiently after an intense workout, thus improving recovery. 


Increase strength & muscle growth

Boire et al demonstrated that men engaged in resistance training programs while supplementing with whey proteins showed greater improvements in strength than men using resistance training alone. This is mainly due to the high Branched Chain Amino Acid (BCAA) content in whey protein. It has been found that the quality of a particular protein for enhancing muscle mass and strength is related to its Leucine content. 


Enhance protein synthesis

Whey proteins can contain up to 26% BCAA, which are efficient substances for synthesizing new proteins where BCAA Leucine acts as a signalling molecule for initiation of protein synthesis. 


Increase bioavailability of essential amino acids

Research found that the amino acid profile in individuals’ dietary proteins influences their nitrogen utilization. This means poor quality dietary protein intake have been shown to increase nitrogen losses and limit protein synthesis, therefore ingestion of whey proteins containing high essential amino acids can reduce nitrogen losses (Boire et al, 1997).

Whey Protein Isolate (WPI) Protein Powder

What is Whey Protein Isolate?

Whey Protein Isolate or WPI is a very fast-digesting dairy protein that consists of at least 90% protein, with almost no carbohydrates or fats. WPI is also 99% lactose-free, making it suitable for most people who are lactose intolerant.



Where do you get your whey protein isolate from?

We purchase only New Zealand whey protein isolate. Unfortunately, it is impossible to source from within Australia. We do get out WPC and casein from Australian suppliers.



Where is your whey protein isolate mixed?

All our protein powders and other products are blended and packed at our export-grade production facility in North Brisbane.



Whey protein isolate vs whey protein concentrate

The nutritional and pricing differences between WPI and WPC result from a secondary step in the manufacturing process. During production, WPC is microfiltered once, while WPI is filtered a second time. This second filtration removes more fat and carbohydrate from the original product, producing a more refined protein. This process means that WPI is a more pure whey protein than WPC.

The lower lactose content of WPI the best protein powder for lactose intolerance. The majority of intolerant individuals can use WPI without experiencing any digestive symptoms.

WPC contains more milk fat than WPI with around 4-7% fat. This is not necessarily a bad thing, as this fat can contain beneficial nutrients not found in WPI.

Whey Protein Isolate is also quicker to digest than WPC.

Whey protein isolate benefits

Whey protein contains all 9 essential amino acids, including an extra high dose of the amino acid leucine, which has been shown to effectively stimulate muscle protein synthesis and help build more muscle mass. Since WPI is the purest protein source available for consumption, it helps maintain and build muscle tissue and prevent catabolic activity during high-intensity resistance training sessions.

You can mix your protein with as much or as little liquid as you choose depending on your personal preference. We provide guidelines on our packaging.



Are whey protein supplements safe?

The amount of whey protein you need daily depends on your activity levels and goals. A highly active individual, an athlete or bodybuilder's protein requirements would significantly differ from someone who has a more laidback sedentary lifestyle.

Athletes can safely eat more protein than people who are not physically active. In fact, an athlete who does not get enough protein will sustain some muscle damage and take longer to recover. Whey protein isolate does not cause any health issues in those who are otherwise healthy.



Can I use whey protein isolate when pregnant or breastfeeding?

Please ask a medical professional such as a GP or dietitian before using protein powder when pregnant or breastfeeding. There is nothing inherently unsafe in VPA protein powder for pregnant or breastfeeding women. Please refer to this blog for more information.( https://www.vpa.com.au/protein-safe-for-pregancy)



Is whey protein vegan?

Whey protein is not vegan friendly because it is a dairy product. Whey protein isolate is suitable for vegetarians. People with milk allergies or lactose intolerant should avoid whey protein, or take caution.



When is the best time to take a protein shake?

The best time to take protein shakes depends on your health and fitness goals and whether you want to lose weight, build muscle, or preserve muscle.

Protein helps to curb our appetite by reducing levels of the hunger hormone, so if losing weight is your goal, consuming a protein-rich snack between meals would be ideal to lead to fewer calories later in the day.

Protein is also important for building muscle and strength. If this is your goal, you need to be consuming more protein than your body breaks down naturally during intensive training. It is safe to take protein shakes after your exercise.



Can I trust any supplement company selling whey protein?

Because the supplement industry is unregulated it can be hard to put your trust and hard-earned money into the hands of a company that claims to offer the highest quality whey protein. So to ensure that you are receiving exactly what you are paying for, look to see if the company publishes their whey protein 3rd party lab tests on their website if they don’t then we strongly recommend you do not buy their product if they do then you are in safe hands.
