At Discount Supplements, we stock the best whey isolates from leading brands like The Health Project and Efectiv Nutrition in a range of great tasting flavours.

 

Why whey isolate? 

Whey protein isolate (WPI) is a refined form of whey protein. It's processed to remove nearly all fats, sugars, and lactose making it easy to digest and kinder on your stomach. Whey isolate protein powder contains a higher percentage of protein per serving compared to regular whey concentrate. Whey isolate is ideal for anyone wanting a clean, efficient way to meet their protein goals without unwanted extras. It supports you to build lean muscle, recover faster after intense workouts, and stay on top of your nutrition. 

 

The benefits of whey protein isolate

Packing in all of the same great benefits as standard whey protein but with purer ingredients, whey protein powder gives you:

  • High protein purity at around 20 - 27g of protein per 30g serving. This not only boosts muscle growth and repair but means you’ll meet your daily protein target with no problems. 

  • Fast absorption - whey isolate is rapidly digested and absorbed into the bloodstream, making it an excellent choice post-workout when your muscles need protein the most

  • Low in fat, sugar, and carbs, with typically less than 1g of fat and sugar per serving. Perfect for anyone on low-calorie, low-carb, or cutting diets. 

  • Reduced lactose and therefore less likely to cause digestive discomfort compared to other types of protein. Whey isolate is often favoured by people with a sensitivity to lactose

  • Enhanced muscle development thanks to a rich profile of BCAAS, especially leucine, which triggers muscle protein synthesis to help you reach your strength goals

  • Premium supplementation and a preferred choice for athletes and sports professionals, whey isolate is used by elite athletes, bodybuilders, and nutritionists alike

  • An easy to mix protein shake option that can be blended with milk, water or in smoothies with no clumps

Frequently Asked Questions

What is whey isolate protein?

Whey isolate protein is a highly refined form of whey protein. It’s derived from milk during the cheese-making process and undergoes extra filtration to remove most of the fats and carbohydrates. This results in whey isolate protein containing around 90% or more protein per serving and is why it is chosen by many people who want to increase their protein intake without an excess of calories. Whey isolate is quickly absorbed by the body, making it particularly popular with athletes for its ability to help with muscle repair and growth post-workout. It generally contains minimal lactose too, and so is more tolerable for anyone with a sensitivity to lactose.

How is whey isolate different from whey protein?

The key difference between whey isolate and whey protein concentrate is the nutrient composition and the refinement process. Whey protein is a more general form of protein supplement typically including a combination of protein, fats, and carbohydrates. Whey isolate undergoes additional processing which removes most of the fats and carbohydrates, and results in a higher protein content and lower lactose levels. Whey isolate protein powder may have a higher price tag because of its purity. Both types of protein provide essential amino acids that support muscle growth and recovery, and are great for anyone who trains regularly or has an active lifestyle. Choosing which form will come down to nutritional needs, personal taste and any dietary requirements.

Why should I take whey isolate?

As a high quality protein source, whey isolate is a smart choice for people who want post workout support to repair muscles and increase strength gains. The rich amino acid profile t helps in the repair and growth of muscle tissue. It is particularly abundant in leucine, which plays a critical role in muscle protein synthesis. The lower fat and lactose content of whey isolate makes it suitable for those watching their calorie intake or anyone who is lactose intolerant. The versatility of whey isolate protein means it can be easily mixed into smoothies and shakes, offering a convenient and effective way to reach your daily protein goals, support weight management and build muscle.

What is the best way to take whey isolate protein?

Whey isolate protein should ideally be taken 30 minutes to an hour after your workout. The rapid absorption rate means it can get to work quickly repairing strained muscles. You can mix it with water, milk, or a milk alternative. Using water is better for even faster digestion and lower calorie intake. Milk can make your protein shake creamier and add more nutrients like calcium. If using whey isolate to supplement a daily protein intake, it can be used in meals or snacks, for example blended into smoothies, stirred into overnight oats, or baked into healthy snacks. Always follow the serving instructions to make sure you are getting the right amount for your individual needs.
