Whey Protein

Whey protein is a byproduct of cheese production, and it contains many essential amino acids which are naturally found in animal proteins. It is used as a supplement because it helps to keep you full and satiated; it is rich in vitamins, minerals, and can help give your body the nutrients it needs to function properly. And you can never ignore their many benefits.

Whether you want to lose some extra body fat or gain strength and muscle mass, protein intake is crucial in keeping your body fit and healthy. However, fulfilling your body's protein needs just by your diet may seem to be a hard task. But, with the right protein supplement, you can get muscular in your gym while still being able to maintain your all-day protein intake.

However, not all protein supplements are equal in terms of efficiency and quality. Some types are better than others, like whey protein. The best part about whey proteins is their ingredients content. They also contain amino acids that make them easy to digest and absorb. So, if too are looking to buy the best one, this 2-min-read article will give you an informative brief about whey proteins.

Happy Reading!

What Is Whey Protein?

It is a byproduct of cheese manufacturing and a popular supplement for those who want to gain muscle and lose weight. As the name suggests, whey protein is derived that you from the cow milk through hydrolysis and consists of 20% whey protein. It is a great protein for muscle building and weight loss and a great dietary supplement to improve the quality of your life.

Whey Protein Supplements Can Help Boost Your Protein and BCAA Intake

It is a dairy-derived protein that contains high levels of Leucine, Isoleucine, and Valine. These branches of amino acid chain (BCAA) are specifically to supplement the body's protein requirements. The BCAAs are essential for muscle recovery after intense exercise and are needed for building lean muscle mass. They also promote optimal muscle growth and help reduce lactic acid levels in the body, which may help you burn fat.

Types of Whey Protein

Even whey protein is further into three types. Well, this categorization is done based on how they have been processed. Continue reading to find out more.

  • Concentrate: Whey protein concentrate is an extremely fine powder from ultrafiltration from milk. This type contains low contents of carbs and fats, along with some levels of lactose(milk sugar). The percentage of protein can carry depending upon the level of concentration. For high concentrated supplements, the protein percentage can go up to 90%, whereas for the lower end, it stays at 30%.
  • Isolate: After further processes, fat and lactose levels are more reduced. The mixture contains 90% protein, or it can be higher too. However, with less fat and lactose, it also lacks some helpful nutrients.
  • Hydrolysate: Hydrolysis is a necessary process that a human body performs to absorb protein contents. This type of whey protein is hydrolyzed. That means it comes in the predigested form. Also, it can increase insulin levels to around 28% to 43% more than isolate-whey protein.

Effects of Whey Supplementation on Muscle Mass and Strength

Building blocks

Muscle fibers are of a central sarcoplasm and a surrounding myofibril. These structures provide the support, repair, and growth of muscle. The protein building blocks such as leucine, lysine, and methionine, besides the other BCAAs, stimulate muscle protein synthesis. Whey protein is the abundant source of milk and one of the most popular sports nutrition supplements.


They are natural substances produced by the body to wake up cells and signal the rest of the body that there is a need to grow, develop, repair, or reproduce. Hormones are of two types: anabolic and catabolic. Anabolic hormones stimulate the growth, increase bone density, and improve muscle mass. The intake can increase the production of anabolic hormones in the body, which helps build muscle strength and mass.


Whey protein is a powerful source of leucine. Leucine is one of the key amino acids that allows storage and synthesis of protein in muscle cells. Besides, it stimulates muscle protein synthesis at the molecular level.

Fast absorption

The body absorbs Whey protein rapidly. That is because the digestive tract breaks it down into its component amino acids. Moreover, fast absorption positively influences muscle protein synthesis. Also, the use of whey protein regularly is associated with an increase in muscle mass and strength.


Worldwide, whey protein is the most popular protein supplement. This is, thus, also true of the United States, as the total value of the Whey protein market in the USA has increased at a CAGR of 13.6% between 2014 to 2018.

It has become increasingly difficult to find a pure source of whey protein in recent years, as milk has become more and more contaminated by hormones, antibiotics, GMOs, and other contaminants. Therefore, it's important to buy only high-quality and branded supplementary products.
