Whey Protein

All You Need To Know About Whey Proteins

What Is Whey Protein? 
Whey protein is a highly concentrated powder form of protein. This high-quality
protein is naturally found in milk products. So what’s the difference between milk and whey? Milk is made of two proteins – casein and whey. Whey protein can be separated from casein in milk, or it can also be formed as a byproduct of cheese formation process. Whey is mostly available in powder form and for consumption, you can mix it with water or skimmed milk to make protein shakes. These shakes are perfect as pre and post workout snacks.

Whey protein is considered to be a complete protein. It contains all 9 essential amino acids required by the body for various bodily functions. The best part about whey is that it has low lactose content and is easy to digest. This means that people with lactose intolerance can also consume whey protein supplements.

Whey supplements are a good way to add high-quality protein to your diet. There are 3 major types of whey proteins –

1. Whey Protein Concentrate
This is the most basic form of protein found in protein supplements and the protein content varies between 25% and 89%. Whey protein concentrate is best for beginners. 

2. Whey Protein Isolate 
This is the purest form of protein. It contains 90 – 95% protein and is perfect for athletes and bodybuilders. The low fat and lactose content means that it is suitable for lactose intolerant people as well. 

3. Whey Protein Hydrolysate 
This gets most easily absorbed in the body and the protein content varies between 80% to 90%. Wheyproteinhydrolsate is most commonly used in infant formula, and sports and nutrition formulas.

How is Whey Protein Made? 

  1. The milk used to extract whey is derived from cows. It consists of 3.5% protein, 4% fat, and 4.6% lactose. 
  2. This milk is unpasteurized and is then cooled 4degree C and then transported in refrigerated trucks to cheese making factories 
  3. The milk is then pasteurized and cooled. At this stage, milk contains 80% casein and 20% whey. 
  4. The liquid is separated from the curds using enzymes. The casein is matured into various cheeses. 
  5. Liquid whey is then filtered to remove fats, minerals, water, and lactose and whey proteins micro-filtered to convert it into whey protein concentrate. 
  6. The high protein liquid whey is spray dried into a powder. 
  7. This concentrated version is packaged and sent to various warehouses to be formulized
  8. Once formulized, it is sent to stores from where you can buy your favorite brand and flavor.

  • Bloating 
  • Gas 
  • Diarrhea 
  • Nausea 
  • Acne

Whey protein is a high-quality protein naturally found in dairy. It is a complete protein containing all of the essential amino acids that your body needs to build muscles and is easy to digest. 

For something as simple and pure as whey several myths flourish. To get the facts right, whey, a premium source of protein is the watery liquid leftover from the curdled milk of cheese making process. Cow’s milk has 20 percent whey and 80 percent casein or milk protein.  An abundantly rich source of branched-chain amino acids whey stimulates protein synthesis, which makes it an imperative nutrient for gym fanatics, bodybuilders, athletes and fitness enthusiasts. For someone on a diet, whey is an absolute must, because dieting is catabolic. As much as you like to lose fat, during a diet, your body holds on to it, as a source of energy. Therefore, for energy, the body attacks muscle as a protein source, which can be a self-defeating exercise in the pursuit of lean muscle.

Whey comes as the way out.  BCAAs (branched-chain amino acids) in whey, particularly leucine stimulates protein synthesis and might do so to a greater extent than a normal protein on its own.




Predigested protein: The long protein chains in the whey protein have been broken down into shorter chains called peptides.  This makes the whey protein more easily absorbed by the body and may reduce the potential for allergic reactions.

A study published in the Journal of The International Society Of Sports Nutrition found that subjects who consumed whey protein after training experienced improved blood flow to their forearm muscles, enhancing the delivery of muscle-building nutrients such as oxygen and hormones. It is also generally understood that the anabolic effects of weight training are increased through the consumption of whey protein because amino acids are rapidly driven to skeletal muscle tissue.

The benefits of whey go beyond the realm of fitness and bodybuilding. Whey is a virtuous source of protein for anyone. Research studies have concluded that whey protein may help in the fight against some common forms of cancer including prostate and colon.
