Let’s begin by understanding where it comes from!

Whey protein concentrate as well as Whey protein isolate are derived from milk as a by-product of a cheese making process. Although the sources are same, each one is processed in a different way and therefore ends up being a product with different specialities. 

However, here we are going to elaborate about whey protein isolates. This 2-minute read should provide you with some basic information about what it exactly is. How is it different from the other whey protein variants? Pros, cons and the bottom line of who should be consuming it.

What exactly is it?

Whey protein isolate is the purest form of whey and it is a complete protein. It contains all essential amino acids that the body needs to support lean tissues. When Whey protein concentrate undergoes a filtration process that leads to further reduction of fat and lactose, Whey protein isolate is made. 

Because it is a rich protein source, it is naturally high in protein percentage and it has a greater amount of essential amino acids, with nil to negligible amounts of fats and lactose. 

How is it different?

Whey protein concentrate’s protein content is around 80 - 85%. The remaining 15-20% content is milk derived fats and carbohydrates in the form of lactose. On the other hand, Whey protein isolate’s protein content is 90% and above with minimum levels of fat and lactose. This makes it a denser source of pure proteins.

  • Quicker absorption- Post your regular exercise, the body needs to refill its protein needs of broken muscle fibres. By consuming Whey Protein Isolate, a fast-absorbing protein post workout, you're supplying your muscles with the amino acids they need to repair and grow, precisely when they benefit the most.
  • Whey protein isolate - with its almost negligible lactose content - is easily digested and an ideal option for those who are lactose intolerant.
  • Low level of Fat is also ideal for individuals with weight-loss goals.


  • There are no clear cons of Whey protein isolate except for it being less in healthy fat bound compounds like immunoglobulins and polypeptides. This is because these fat bound compounds are lost during the additional filtration process.


 Whey protein isolate is the best buy! This is especially true in the following cases-
  • If you are lactose intolerant
  • If you are following a calorie restricted diet and are looking for a supplement with low fat content.
  • If you are looking for a supplement delivering high protein per serving.
  • If you are on a weight loss journey and aim to keep the carbs and fat content low.
