Whey isolate protein is a form of whey protein popular among athletes, fitness enthusiasts and the health-conscious alike. Nevertheless, what exactly is it, what are its benefits and how can you use it best? In this article, we’ll answer all your questions about isolate protein to help you decide if it’s right for you and your unique fitness journey. 

What is whey isolate protein?

Isolate protein is a form of whey protein — a type of protein found in milk. It goes through certain stages of processing that result in higher protein content and less fat, lactose and carbs than other forms of whey, like hydrolysed whey protein and whey protein concentrate. Whey isolate protein is characterised by its rapid absorption and high biological value, which means that the body can use it more efficiently.  

Whey isolate vs. whey concentrate

You may be wondering what exactly the difference is between whey isolate protein and whey concentrate. Although both come from whey, they differ slightly in their properties and protein content.  

Whey isolate protein contains a higher protein content than whey concentrate (around 90%). It also has less carbohydrates and fats and a faster absorption rate, making it a great post-workout protein source.  

Whey protein concentrate typically contains around 70-80% protein and tends to have the best flavour due to the presence of lactose and fat. It’s also slower to absorb than Whey Isolate, although it can be a cheaper option.

Why do I need protein?   

Before you try whey isolate protein or any other type of protein powder, you may wonder why it’s important to watch your protein intake in the first place. Protein is an essential building block of the body and serves many functions.   

Primarily, it’s the main nutrient for building muscle and repairing muscle fibres.  

A protein-rich diet can also help to promote satiety, which in turn can help with weight loss and weight control if you are following an energy-restricted diet.   

Why is isolate protein better than other forms of whey?

What makes whey isolate protein so special? This form of whey differs from other protein sources like soy protein or casein protein in several aspects:  

High-quality protein source: Whey isolate contains all the essential amino acids our bodies need, making it a complete source of high-quality protein that helps build muscle and recover after exercise.  

Higher biological value: the biological value indicates how well the body can use the protein to synthesise new proteins. Whey isolate protein has a high biological value, which means it can be used efficiently by the body.  

Lower lactose content: isolate protein usually has a lower lactose content than other whey protein products, which makes it easier to tolerate for people who are lactose intolerant or have sensitive stomachs.  

Ease of digestion: In general, whey isolate is easier to digest compared to other proteins and is less likely to cause digestive discomfort or stomach problems.  

Low fat and carbohydrate content: whey isolate protein is particularly suitable for people who want to limit their carbohydrate and fat intake, but still need a high-quality protein source.  

How do I use whey isolate protein?

Whey Isolate is extremely versatile and can be used in lots of ways:  

Protein shakes: whey isolate is great for making protein shakes. Mix your favourite flavour with water or milk for a convenient snack between meals or after a workout.  

Smoothies: add a scoop of whey isolate protein to your smoothies to up your protein intake and improve its nutritional value. Our refreshingly fruity Juicy Whey Isolate is perfect for this.   

Protein popsicles: for an extra cool down on hot summer days, turn your juicy whey shakes into ice-cold popsicles. Find the recipe here: protein strawberry and vanilla popsicles
