Whey Protein vs. Casein Protein

There is a difference between whey and casein proteins. As I elaborate on the differences between each, I will also recommend a particular time frame for using both proteins.

Twenty amino acids make up one complete protein. Eleven of these the body naturally produces are nonessential. The other nine amino acids are essential, and we need to obtain them through food or supplementation since the body does not provide them on its own.

Proteins have a variety of benefits:

  • Supporting growth and maintenance of body tissues
  • Repairing muscle damage from exercise
  • Contributing to muscle growth
  • Increasing the four primary anabolic hormones after digestion (see my previous blog post)

Whey proteins are faster-digesting proteins than casein proteins. 

Whey proteins are found in eggs, chicken, and fish. 

Casein proteins are primarily found in milk, cheese, and beef. These proteins take longer to digest than whey protein because the amino acids have a prolonged amino acid ingestion.

Understating this difference will be helpful because you will know which protein to have at a specific time.

Before and immediately after training, I highly recommend fast-digesting proteins to help enhance muscle recovery.

Before you go to sleep, I recommend casein proteins. The reason you want casein protein before you go to sleep is that your body will be at rest for a prolonged period. Since the body is at rest and casein protein has extended digestion into the muscles that need recovery, this will be more optimal.
