What Is The Difference :

Whey Concentrate vs. Isolate

Most of us struggle to find the best protein supplement. We have received queries on which protein supplement we advice, which is better – whey concentrate or whey isolate. This post will hopefully clear your doubts about what is Whey and What Is The Difference : Whey Concentrate vs. Isolate.

What is Whey ?

Whey is the liquid portion of the milk which is separated from the curds during the process of making cheese. You may say, whey is a bi-product formed during cheese production. Whey contains nutrients – proteins, carbs, fats, vitamins and minerals.

What Is The Difference : Whey Concentrate vs. Isolate

Why is Whey so popular?

Whey has a strong amino acid profile and gets absorbed by the body with ease. This makes whey, the most popular protein nutrition supplement. Whey protein is found to promote the following –

  • Muscle formation
  • Decrease insulin sensitivity
  • Decrease appetite

What Is The Difference : Whey Concentrate vs. Isolate

To understand the difference between Whey Concentrate and Whey Isolate, one should know how whey is prepared. In its natural form, whey contains fat and lactose (milk sugar). In order to remove these, filtration process is done. The end product is a more concentrated protein which can be concentrate, isolate or hydrolysates. I won’t go into hydrolysates for now.

Whey protein concentrate is created by pushing milk through a very small filter which allows water, minerals, and other organic materials to pass though. The big proteins that are unable to pass through the filter , are collected. This yield of protein powder is called whey concentrate. Whey concentrate has 70 – 85% protein but 5 % lactose too. Lactose intolerant people face problems consuming whey concentrate.

Whey concentrate also contain various protein subfractions that have significant biologic health benefits. Now these must remain in their original form (the 3-d form that exists in nature) for them to exhibit these health benefits.

Whey concentrate is further processed and purified into Whey Isolate which has very low levels of carbs and fat. In short, its almost pure protein. Lactose intolerant people can safely use Whey Isolate. Needless to say, Whey Isolate is more expensive that Whey Concentrate. The 3-d protein subfractions do get degraded in this process. But amino acids remain unaffected and the muscle building capability of protein remains intact.

I hope I was able to explain the difference between Whey Concentrate and Whey Isolate in simple words for everyone to choose a right protein supplement. In my next post, i will elaborate on how to chose a protein supplement for various health goals you might have 🙂

Till then,

Take Care !
