Whey Protein Isolate (WPI)

WHEY PROTEIN ISOLATE POWDER IN AUSTRALIA

If you’re looking to build lean muscle mass, look no further than a Whey Protein Isolate (WPI) to incorporate into your health and fitness regime. While Whey Protein Isolate and Whey Protein Concentrate (WPC) are both whey-based formulas, there are differences in their extraction and filtration methods, resulting in varying lactose levels and speeds of absorption. 

Boasting a high bioavailability and naturally occurring amino acids, Whey Protein Isolate Protein Powders are meticulously filtered, while being high in protein, and low in carbohydrates and fats. Ideal for all fitness levels, Whey Protein Isolate Protein Powders are fast-digesting and low in lactose, making them a great choice whether you are looking to gain lean muscle, have digestive issues or want to aid your post-workout muscle recovery.

FAQs About WPI Protein

What is whey protein isolate?
Whey protein isolate (WPI) is derived from the same milk concentration as whey protein. Whey protein isolate has been filtered in a process that helps remove much of the lactose in the powder itself. This creates a leaner and lower fat protein source than other protein sources (Gray, G. 2017).

Gray, G. 2017, ‘Whey Isolate vs. Whey Concentrate | What’s The Difference’, MyProtein, accessed 15 September 2022, https://us.myprotein.com/thezone/supplements/whey-isolate-vs-whey-concentrate/#:~:text=Although%20both%20Whey%20Protein%20and,and%20lower%20fat%20protein%20source
Is whey protein isolate good?
Whey protein isolate contains all 9 essential amino acids, making it a complete form of protein. Whey protein isolate is great for repairing muscle tissue, reducing tissue damage after a session and enhancing the gain and maintenance of muscle mass (Peak Nutritionals. 2020).

Peak Nutritionals Team. 2020, ‘What Is Whey Protein Isolate Good For’, Peak Nutritionals, accessed 15 September 2022, https://www.peaknutritionals.com.au/blog/what-is-whey-protein-isolate-good-for/#:~:text=Whey%20protein%20isolate%20contains%20all,mass%2C%20and%20even%20improving%20endurance
What does whey protein isolate do?
Operating similarly to a standard whey protein, an isolate is higher in protein and lower in lactose and fat. Whey protein isolate is useful for muscle building, performance enhancement and tissue repair.

Consuming a WPI protein post-workout can help you improve your lean mass and optimise your recovery while maximising your performance benefits and gains (Hinchman. W. 2020).

Hinchman, W. 2020, ‘The Ultimate Guide To Whey Protein Isolate - Benefits, Uses, Side Effects’, Swolverine, accessed 15 September, https://www.fitandwell.com/features/whey-protein-vs-whey-isolate-which-protein-powder-is-right-for-you
What's the difference between WPI and WPC?
Whey protein isolate has a higher protein count than your standard whey protein. An isolate generally contains 90% or more, while a typical concentrate typically has 70-80% (Gunnars, K. 2018). The process that removes much of the lactose from the powder also helps to concentrate it to some extent.

Whey isolate generally has a lower calorie, carbohydrate and fat count, making it ideal for mixing with water for a low-calorie & high-protein drink (Evans, M. 2022).

Gunnars, K. 2018, ‘Whey Protein 101: The Ultimate Beginner’s Guide’, Healthline, accessed 15 September 2022, https://www.healthline.com/nutrition/whey-protein-101

Evans, M. 2022, ‘Whey protein vs whey isolate: what’s the difference?’, Fit & Well, accessed 15 September 2022, https://www.fitandwell.com/features/whey-protein-vs-whey-isolate-which-protein-powder-is-right-for-you
Is whey protein isolate better than concentrate?
Whether or not whey protein isolate is better than concentrate mostly depends on your individual body goals. If you struggle with digestive issues, are sensitive to lactose or are looking to increase lean muscle mass with a low-carb option, an isolate protein may be a better choice for you. However, the nutritional benefits between an isolate protein and concentrate protein do not vary greatly and are both great options for achieving your training and body goals.
Is whey protein isolate good for weight loss?
Yes, whey protein isolate is a great source of protein that is easy to digest. It can be effective when trying to lose weight if taken following exercise.

Whey protein isolate helps you to build muscle while burning fat, and your body is able to digest it faster than any other form of protein. Whey protein isolate may help you improve your digestive system and hit your weight goals more effectively and efficiently (Khosla, S. 2020).

Khosla, S. 2020, ‘Whey Protein For Weight Loss: How To Consume This Protein Supplement To Shed Kilos’, NDTV Food, accessed 15 September 2022, https://food.ndtv.com/weight-loss/whey-protein-for-weight-loss-how-to-consume-this-protein-supplement-to-shed-kilos-1892841
Does whey protein isolate cause acne?
Acne can be caused by a number of outside factors including your lifestyle, diet, hormonal imbalance, sugar intake, allergens and other medical conditions. Intolerances to dairy can sometimes lead to acne, so if you’re looking to stay on the safe side, a premium WPI protein that is low in lactose may be a great option. Alternatively, we do have a range of vegan plant protein that may reduce any potential acne risks.
What is whey protein isolate made from?
Whey is isolated from milk. Milk contains two main proteins - casein (80%) and whey (20%). Whey is present in the liquid part of milk and is a by-product of the cheese-making process. Whey tends to contain 9 essential amino acids, which can help improve your muscle mass.

Whey protein isolate is made by using enzymes to curdle milk and separate the watery part. The manufacturers pasteurize this liquid whey and process it until it is refined. They use two processes called Membrane Filtration and Ion Exchange Technology (The Island Now. 2022).

The Island Show Team. 2022, ‘What is whey Protein Isolate Made Of? Isolate Vs Concentrate’, The Island Show, accessed 15 September 2022, https://theislandnow.com/blog-112/what-is-whey-protein-isolate/
Is whey protein isolate gluten-free?
Whey protein isolate is naturally gluten-free because the whey protein itself contains no gluten. Typically all whey protein isolates will be celiac-safe, but you should always check the packaging to be sure they are no added ingredients that contain gluten.
Is whey protein isolate dairy-free?
Whey protein isolate is not dairy-free as it contains some lactose, despite containing less than a whey concentrate or hydrolysate. As it contains around 90% protein, an isolate might still be compatible if you only have mild lactose intolerance.
Is whey protein isolate vegan?
Whey protein isolate is not vegan-friendly due to the whey, which comes from milk. While no form of whey protein is vegan-friendly, there are other plant-based and dairy-free alternatives to choose from.
