Whey protein has all the 9 essential amino acids that your body cannot make and relies on the external food courses to acquire them. People mainly consume it to increase their protein intake, boost their athletic performance, and increase their muscle growth. In addition to these benefits, there are many other benefits of taking whey which we will discuss further in the article.
In this article, you will learn the reasons why you should consume whey powder, how you should consume it, and what its side effects are.
Why is whey protein good for you?
Whey protein is a complete protein which means you will not have to eat different food sources to get different amino acids. It also gets absorbed in the body very fast, which makes it more effective compared to the other kinds of proteins.
It is known for producing many healthy effects on the body. Below is the list of the benefits of whey protein that will show why this healthy supplement is good for you.
Increases muscle mass
The main reason behind the popularity of whey protein powder is its ability to increase muscle mass, muscle strength, and athletic performance. It contains several amino acids like leucine that boost the production of muscle protein.
Studies prove that whey protein is more effective in increasing muscle mass compared to other protein sources like casein and soy. [1, 2] It also prevents age-related muscle loss and helps you maintain a better-looking body.
Reduces body weight
Whey protein is a satiating protein which means it gives you a feeling of fullness which then makes you less hungry and you consume fewer calories. It reduces your desire to eat, and in this way, overweight people may observe weight loss by consuming whey protein powder regularly.
It is the most effective protein in this regard compared to the other kinds of proteins like casein and soy. 
May reduce blood pressure
High blood pressure is one of the leading causes of heart disease. Studies show that the consumption of dairy products can help people with their high blood pressure.  This effect is mainly due to the presence of certain peptides (called ACE-inhibitors) in dairy products.
Whey protein also has ACE-inhibitors. In one study, overweight people were given whey protein supplements regularly. At the end of the research, a 4% reduction in the systolic blood pressure of the participants was observed. 
May increase the production and sensitivity of insulin hormone
Type 2 diabetes is a disease in which your blood sugar level rises because your body cells do not respond to the insulin hormone, which is responsible for taking sugar from the blood to different body cells.
Studies show that whey protein has the ability to increase insulin production in the body and increase sensitivity which reduces blood sugar levels.  Therefore, people fighting off type 2 diabetes may find this supplement effective in managing their blood sugar levels.
