Whey Protein Concentrate vs. Whey Protein Isolate

Whey Protein Concentrate vs. Whey Protein Isolate


No, Not All Whey is Made the Same. 


Whey protein is one of the most heavily researched proteins available and contains a number of benefits that help with everything from gaining muscle to lowering blood pressure. It is often recommended by nutritionists, trainers and coaches because of its versatility and effectiveness. However, not all whey is made the same.


There are three types of whey proteins: Whey Protein Concentrate, Whey Protein Isolate (WPI) and Hydrolyzed Whey Protein. All of these are derived from cow’s milk but the nutritional benefits vary depending on the processing method.


We are often asked the differences between Whey Protein Concentrate compared to Whey Protein Isolate (WPI), and why we decided to use Isolate in all of our whey formulations. Here are 5 main reasons. 


1. Lower Levels of Lactose 


Did You Know? Almost ¾ of the world is lactose intolerant. 


Casein and Whey are the two types of protein found in milk, and they both contain lactose. If after consuming Whey products you find that you have digestive discomfort or abdominal pain, it may mean that you are lactose intolerant, or just sensitive to the effects of lactose. 


The great thing about WPI is that it is filtered in a way that removes the lactose. Whey Isolate has around 1% of lactose, while Whey Concentrate can have up to 55%. Most people who have issues with dairy are able to consume WPI with little to no side effects. 


2. Nutrition Content 


Whey Isolate has 90-95% of pure protein, while Whey Concentrates contain around 70-80%. The higher amount of protein is a reason enough for most people to make the switch. WPI is also naturally rich in BCAAs, Glutamine and amino acids, yet still low in carbs and fat. This helps your body absorb the protein without the extra junk that can end up slowing you down.


3. No Bloating 


You may have heard someone you meet mention that whey protein makes them bloated. This is likely due to Whey Protein Concentrate. Due to high carb content and lactose, many people also find that Whey Concentrate is hard for them to digest and disrupts their GI tract. The processing required to create Whey Isolate, removes the culprits that create bloat in your tummy. Whey Isolate also has lower amounts of casein than any other whey protein.


4. Purity 


To create WPI, Whey Concentrate is filtered and refined. This makes it the purest and cleanest protein available since the majority of things things that aren’t actually protein get filtered out. This also makes it much more expensive to manufacture compared to Whey Concentrate.


Most brand’s use Whey Concentrate in their products because it is more cost-effective. 


5. Fewer Calories 


Whey Isolate has fewer calories per serving, even though you’re getting the benefits of higher protein. This is better for weight maintenance and weight loss. This also allows you to get more calories from whole, nutritious foods.



Whether you’re looking to shred, bulk or simply get healthier, we believe that WPI is the way to go.
