Do you know your whey protein?

Do you know your whey protein? - GNC India

Protein is for everyone. Only the recommendation varies as per your lifestyle, age, and gender. Different types of protein can be useful for different goals and at different times in the day.  One of the most common and well-known types of protein is  Whey.  Milk has two proteins: Casein (approx. 80%) & Whey Protein (approx. 20%).

Casein, like complete protein source that is derived from dairy. It’s known as a slower-digesting protein, which is why you’ll see it suggested before bed, or as part of a meal replacement shake

Whey protein is a high-quality protein powder derived from cow’s milk.

  • Whey protein is more soluble than casein & also has a higher quality rating.
  • Whey protein has all 20 amino acids & all 9 essential amino acids

Whey protein is one of the most commonly used proteins in sports nutrition. It is a fast-acting protein that provides an excellent source of readily absorbed amino acids, including the complete essential amino acid profile and the branch chain amino acids (BCAAs). Whey protein is a perfect protein for workout recovery and muscle building because whey is digested more rapidly than other proteins.

Shopping for a protein powder was much easier years ago. It used to be you had to choose between whey, casein or soy. Whey and casein are still widely popular, but now you have to choose your type.

Do you want a protein isolate or a concentrate? Would you like that hydrolyzed? Should you buy a pure product or is a blend the better choice?

If you’re confused by all of the varieties, you’re not alone. Let’s take a closer look at the different forms so that you can decide for yourself which would be best for you and your goals.

Whey is produced during the process of making cheese, which starts when certain enzymes are added to milk, causing it to separate. Not all whey proteins created are equal. Whey protein commonly is categorized into 3 distinct varieties.

Whey Concentrate:

  • Commonly known as WPC. Whey concentrate is fractionated and dried so the protein content is about 80%. The other 20% is remaining constituent parts: fat, cholesterol and lactose than other two whey proteins i.e. isolate and hydrolysate.
  • It contains less protein gram for gram and higher levels of fat, cholesterol, and lactose than other forms. As compared to other Whey, it tastes the best and considered to be a fair source of protein.
  • Good for customers who want a general protein supplement that will help improve their overall health.

Whey Isolate:

  • Commonly known as WPI. Further purification to WPC leads to whey isolates. Whey isolate is fractionated and dried so that the protein content is about 90%. Hence fast absorbing.
  • Whey isolate is a form of whey purified without the use of heat.
  • Isolates tend to be lower in lactose, fat, and cholesterol than whey concentrates and hence provides more protein and less of non-essential nutrients.
  • Generally 97% lactose-free, with virtually no fat.
  • Recommended for sportsmen for rapid recovery and lean muscle gain. Since it is absorbed quickly, it maximizes the anabolic response to the exercise.

Whey Hydrolysate:

  • Hydrolysate whey is made by treating the relatively large protein polypeptides in whey with enzymes that break them down into shorter chains. Also known as peptides.
  • It is digested and absorbed faster in the intestines and may reduce potential allergic reactions.
  • Good for the customers looking for a post-workout protein that rapidly absorbs.

So, which one to buy??

Well, there is no direct answer to it, but depending on your need you can choose the required whey proteins.

Blends are considered to be very beneficial as it gives benefits of both types of proteins.


Whey in blend form helps to enjoy the benefits of different types of whey protein in one powder. Many blends allow customers to reap the benefits of different types of proteins without having to purchase multiple products.
