Published On:

If you’re not able to get enough protein from your daily diet, then a whey protein supplement is all that you require!

However, among different types of whey protein powders out there, you might get confused about which one would be the best for your health. What if we inform you that whey isolate is known to be the best and purest form of whey protein? Yes, you heard it right!

In this article, we will take a closer look at whey protein isolate and some of its benefits so that you can easily make a decision.


What Is Whey Protein?

To understand whey isolate, you first need to know what whey protein is. Whey protein is a milk-based protein. During the process of making cheese, it is separated from the milk.

It is then dried and processed in powder form for consumption. The best part about whey protein is that it is easy on the stomach and contains all the vital amino acids.


 What Exactly Is Whey Protein Isolate?

Now that you are aware of whey protein, let’s have a look at whey protein isolate. Whey isolate is a natural by-product of the cheese manufacturing process. It goes through a rigorous filtration process. As a result, the extra carbs, fats, cholesterol, and lactose get separated from the protein and what is left behind is a more refined form of protein.

Whey isolate is considered the purest and best form of whey protein. As compared to other forms of protein, it is more expensive and higher (90%-95%) in the percentage of protein and low in carbohydrates and fats, and calories.


Who Should Opt For Whey Isolate Protein?

Generally, whey protein isolate is recommended for:

1. People Who Are Lactose-Intolerant

Lactose Intolerant

Whey isolate can be the go-to solution for lactose intolerant people and also for those suffering from digestive problems and bloating on lactose intake.


2. People Who Want To Lose Weight

Want To Lose Weight

Whey protein isolate is really good for people who want to keep an eye on their fat, carb, and calorie intake to lose weight. Its low carb and high protein formula help the body in quickly absorbing the protein. This helps in controlling appetite and prevents one from over-eating.

Thus, consuming a protein shake containing whey isolate will always contain fewer calories, fat, and carbs than any other type of whey protein and help in shedding off those extra pounds.


3. People Who Have A High Budget

High Budget

As compared to other protein supplements, whey isolate is relatively more expensive. The reason is that it has high protein content and goes through an extensive manufacturing process. Therefore, if you have enough budget then go for a whey protein isolate supplement.


Health Benefits Of Whey Protein Isolate

We have listed below a few health benefits of consuming whey protein isolate regularly:

1. Muscle Recovery

Muscle Recovery

Whey protein isolate contains all the nine essential amino acids, also known as Branched Chain Amino Acids (BCAAs). These amino acids help the muscles to recover after heavy exercise.

For instance, amino acids like glutamine in whey isolate stimulate muscle protein synthesis and prevent tissue damage after an intense workout session.


2. Low Carb And Fat Content

Low Carb And Fat Content

While most of the commercial protein supplements are high in fat and carb content, whey isolate contains zero to minimal farms and fats. That’s what distinguishes it from other types of whey proteins.


3. Reduces Hunger

Reduces Hunger

If you eat a diet higher in protein, you will feel satiated for long. Whey isolate is high in proteins and low in carbs and fat, which helps in reducing hunger pangs.

Reduced hunger levels are directly proportional to higher levels of leucine, lysine, and other amino acids, making Whey Isolate the ideal protein source for increasing satiety.


4. Increases Strength

Increases Strength

As compared to any other protein sources, whey isolate has a higher content of BCAAs, particularly, Leucine. Leucine is the essential amino acid that leads to protein synthesis to occur. Thus, whey isolate stimulates muscle protein synthesis better than any other protein source, resulting in greater gains in strength and lean muscle mass.


5. Easy On The Stomach

There is a high rate of absorption and digestion in whey isolate. Unlike other protein supplements, it doesn’t cause bloating or flatulence. Moreover, it aids in regulating bowel movements.


6. Low In Lactose

Whey isolate has less than 1% lactose in it as compared to other forms of whey protein. Therefore, lactose-intolerant people are advised to opt for whey isolate over other whey protein supplements.


Whey Isolate Recommended Dosage

According to studies, adults need to consume 0.8 g of protein per kg of their body weight. Nevertheless, it can differ according to their health and fitness goals.

The common recommended daily intake for whey isolate is between 25 and 50 g.



1. Does whey isolate taste the same as whey concentrate?

As both whey concentrate and whey isolate are obtained from milk, they have a similar taste. However, since whey isolate is low in both carbs and fat, it is less creamy.


2. What are the best times to consume whey isolate?

Although it depends on your health and fitness goals, it is recommended that you consume whey protein isolate 30 minutes before workout or immediately after waking up.
