The Right Whey To Gain : Whey Concentrate Vs Whey Isolate

The Everyday Question – Whey Concentrate or Whey Isolate.

Whey Concentrate & IsolateThe fitness & sports industry promotes whey protein as one of the major sources of building muscle.

Most trainers and athletes recommend the use of protein powders to meet the daily protein requirement in order to increase strength and recovery.

However, every time I talk to people about supplements, especially whey protein they end up asking me about the difference between Whey Concentrate & Whey Isolate.  Continue reading to know more about the right source of protein to build your muscle THE RIGHT WHEY!

What Exactly Is Whey Protein :

Whey proteins are a mixture of globular proteins isolated from whey, the liquid material created as a by-product of cheese production.

These are commonly marketed as dietary supplements, and various health claims have been attributed to it in the alternative medicine community.

Although whey proteins are responsible for some milk allergies, the major allergens in milk are the casein.

Whey Protein Concentrate (WPC):

Concentrated Whey can potentially cause bloating due to the lactose and carbs in the products. Isolated Whey contains no, or very little, lactose meaning the issue of bloating is avoided.

Both whey concentrate and isolate will digest in the body at the same rate/speed and also contain the same amounts of amino acids (building blocks of proteins).

Isolate contains a slightly higher level of protein content per serving, so naturally, it will have a slightly higher amount of amino acids per serving.

Let’s have a look at the macronutrients of Whey Concentrate and Whey Isolate.


Macros Whey Concentrate Whey Isolate
Protein 20 g 21 g
Carbohydrates 1.5 g Less than 1 g
Fat 1.8 g 0 g

As you can see there isn’t much difference at all in protein content, only 1 g per serving, but isolate contains no fat and barely any carbs.

Whey Protein Isolate (WPI):

Whey Concentrate & IsolatesAlthough both Whey Protein and Whey Isolate are both derived from the same milk concentration, Whey Isolate is simply whey protein that has been filtered in a process to help remove the lactose in the powder itself. This is to create a leaner and lower fat protein source.

The main difference between whey protein and whey isolate is the 2 products offer different protein content, lactose and fat content per serving.

Whey protein concentrate can offer anywhere between 10-15% protein content per serving with over 50% lactose and almost 2% fat. Whey protein isolate contains over 90% pure protein content with under 1% lactose or milk fat.

For anyone who is lactose intolerant or has issues digesting dairy products then whey isolate is very beneficial due to its lower levels of lactose.

Whey Protein Concentrate Or Whey Protein Isolate:

Both Concentrate and Isolate will provide the consumer with almost identical results when it comes to building muscle and supporting your training goals.

The reasons people choose whey isolate over concentrate is due to the lower fat and carb content, and therefore lower calories content per serving.

If you are lactose intolerant then whey isolate is the protein powder for you. Just be careful not to buy a blend of whey isolate and concentrate, as this will remove the benefit of no lactose and lower fat and carb content.

If you are on a strict low-calorie diet or currently watching calories carefully to prepare for a bodybuilding show or competition, whey isolate will be the better product for you.

If you aren’t worried about your current calorie consumption either whey protein concentrate or whey protein isolate will provide you with beneficial results.
