4 Benefits Of Whey Protein That No One Told You About

Whey protein is often viewed as a bodybuilder’s food, but its benefits are not limited to just building muscle size and strength. It is also used extensively as a therapeutic agent.


Whey protein is touted as a functional food that has antioxidant, antihypertensive, anti-tumor, hypolipidemic, antiviral, antibacterial, and chelating properties. 1https://www.ncbi.nlm.nih.gov/pubmed/15253675


Before I describe its awesome benefits, let’s first understand exactly what whey protein is.

What Is Whey?


Milk is 80 percent casein and 20 percent whey. Whey is the liquid that separates during cheese production.


The components of whey, called sub-factors, include beta-lactoglobulin, alpha-lactalbumin, bovine serum albumin, lactoferrin, immunoglobulins, lactoperoxidase enzymes, minerals, glycomacropeptides, and lactose. Whey has immune-enhancing and health-promoting properties. 2http://www.altmedrev.com/archive/publications/9/2/136.pdf

4 Exceptional Whey Protein Benefits


1) Whey Promotes Muscle Strength And Hypertrophy


Whey protein has all essential amino acids and is in higher concentrations than vegetable protein sources. In addition, Whey has high concentrations of branch-chain amino acids (BCAAs): leucine, isoleucine, and valine. BCAAs, particularly leucine, are important factors in tissue growth and repair.


Leucine has been identified as a key amino acid in protein metabolism during the translation-initiation pathway of protein synthesis. It may play a pivotal role in the protein-sparing effect of amino acids. 3https://www.ncbi.nlm.nih.gov/pubmed/10418071>


Whey proteins are also rich in the sulfur-containing amino acids cysteine and methionine. With a high concentration of these amino acids, immune function is enhanced through intracellular conversion to glutathione.


2) Whey Protein Contains Immunoglobulins (IgA)


When a child is born, colostrum is released from the human breast for the first few days. Colostrum is a thick, semi-liquid that contains greater concentrations of immunoglobulins than the later breast milk.


IgA is secreted in breast milk and transferred to the newborn’s digestive tract, providing better immunity than bottle feeding. Whey protein also contains a significant amount of immunoglobulins (10-15% of total whey proteins).


Other components in whey that have significant immune-enhancing and health-promoting properties are lactoferrin, beta-lactoglobulin, alpha-lactalbumin, and lactoperoxidase.


3) Whey Protein Is Linked With Weight Loss


When I make a protein shake from whey concentrate, it’s even tastier than a milkshake. It completely satisfies my cravings for sweets, which in turn helps me avoid eating refined sweet stuff. This is hugely beneficial for me, as I feel I have a major sweet tooth.


This way, drinking protein shakes can surely help anyone trying to lose weight. Furthermore, whey protein helps to build more muscle, which in turn means a higher resting metabolism. A gain of 10 lbs of lean muscle is estimated to burn around 70-100 extra calories per day, and all the calories burned will be from fat.


4) Whey Protein Has The Following Clinical Benefits




Whey protein concentrates have been extensively researched for their role in the prevention and treatment of cancer, and glutathione stimulation is thought to be the primary immune-modulating mechanism. 4https://www.researchgate.net/publication/12126427_Whey_protein_concentrate_WPC_and_glutathione_modulation_in_cancer_treatment, 5https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4744604/




Glutathione deficiency is a common problem for individuals infected with HIV. In an effort to increase cysteine and, ultimately, glutathione, several studies have been conducted on the use of whey proteins in HIV-positive individuals. 6https://pubmed.ncbi.nlm.nih.gov/11168457/


Cardiovascular Disease


Several studies have found milk intake and milk products lower blood pressure and reduce the risk of hypertension. 7https://www.ahajournals.org/doi/pdf/10.1161/hypertensionaha.107.107821


Blood Pressure


One study demonstrated that supplementation with whey protein improves blood pressure and vascular function in overweight and obese individuals. 8https://pubmed.ncbi.nlm.nih.gov/19893505/ However, please note that not all whey proteins are created equal.

How much protein is necessary ? I have heard multiple versions – 1 g/ kg of body weight, 1 g / lb of lean body mass

Hi Arup,
there are numerous studies which points towards the range of 1.4g-2.0/kg of bodyweight. You can check the following link out for more details: https://fabulousbody.com/protein-101-calculating-how-much-protein-you-need-2/

Thank you so much Akash, Its always amazing to learn from the nuggets you keep sending us.

I understand the benefits described are mainly because of the products ingredients. But considering the benefits, how good is it to switch to plant based protein?

Best Regards

Hi Harsha,

That is a wonderful question! What indeed?

The answer to your question lies in your initial assessment of this article’s content.

As you rightly said, it is about the ingredients that go into it.

Proteins are made up of 20 different amino acids and while Vegan or plant based proteins are not always complete sources but they always combine a few types to provide us with complete protein in every serving.

The ingredients used in vegan protein will have their own properties and contribute towards good/ill health, proteins themselves will always be there.

Similar to any non-vegan protein, it is recommended that you purchase a good quality vegan protein supplement with organic ingredients and as less synthetic items as possible.

Good luck!
