For those of you who like sports to increase muscle mass, you may have often heard whey protein and casein milk. You can both use it to increase muscle mass because it contains very high branched chain amino acids (BCAAs). Both of you can also find it in milk. However, do you know what the difference is?

In milk, it contains 20% whey protein and 80% casein. Whey protein is found in the liquid part of milk, while casein is found in milk curd, based on the National Strength and Conditioning Association. Not only is the source in milk, the function of both proteins is also different.

What is whey protein milk?

Protein is known as a protein that is quickly digested by the body. The body only takes a few hours to digest whey protein in milk. Not surprisingly, whey protein also has a high biological value, which is 104 (higher than an egg of 100). This high biological value makes protein in whey milk more usable by the body.

Whey protein is also known to be more anabolic, meaning that whey protein functions to build muscle. This can happen because whey protein has the ability to support surges in the levels of amino acids in the blood needed to start protein synthesis in muscles.

Because of its function, whey protein milk is very suitable for use before, during, or after exercise. Whey protein can be digested by the body quickly so that it can meet the needs of muscle protein in the body quickly.

What is casein milk?

Unlike whey protein milk, casein milk is known as a protein that is slowly digested by the body. The body takes about 5-7 hours to digest casein. This also makes casein only has a biological value of 77. That is, casein protein is less efficiently utilized by the body than whey.

Casein is better known as anticarabolic. That is, casein can be used to prevent muscle damage and to build and maintain muscle tissue. Casein can produce amino all the time so it can prevent muscle damage. Because casein is digested longer by the body, casein is better used when you are not exercising. You can drink casein milk at bedtime. Casein can also make you feel full, so it can be a complement to your dinner before bed.

Which should I use to increase muscle tone?

Milk whey protein and casein, both of which are equally beneficial in supporting muscle growth. Whey protein and casein have different functions, but both complement each other. So, the use of both is the ideal combination to build your muscles. Several studies have been conducted to prove this.

A 14-week study involving men proved that consumption of whey protein and casein before and after exercise / exercise can increase muscle size. Other studies published by the 2004 Medicine and Science in Sports and Exercise also prove that consuming whey and protein casein after exercise together can increase muscle protein synthesis or muscle growth.
