What is Casein Protein? From how to choose to recommended products.

Casein protein. Many people have heard of casein protein, but don’t really know what it is. Simply put, it is a type of protein that helps you feel full and allows your body to absorb protein slowly. In this article, we will introduce the basics of “casein protein,” how to choose it, and recommended products!

What is the difference between “casein protein” and “whey protein”?

Casein protein” and “whey protein” are made from milk. About 80% of the protein in milk is casein, and the remaining 20% is whey. The clear difference is the speed of absorption: whey is absorbed quickly, whereas casein is absorbed over a longer period of time. Since the amino acids can be supplied slowly, it is suitable for dieting and dietary restriction due to its high satiety, and if taken before bedtime, it also prevents catabolism (muscle breakdown) while sleeping. Whey protein is the best choice for the golden hour after training, while casein protein is better when replacing protein with a meal, or when consuming protein before bedtime or on training rest days to achieve greater muscle growth. Note that those who get sick to their stomachs when drinking milk are likely to be ” lactose intolerant ” and may get sick to their stomachs even with casein protein.

Casein x Whey Protein Blends are also available!

It is also effective to mix casein and whey, which are absorbed at different speeds, although it is possible to use different types of protein depending on the timing. Since both effects work, the protein is absorbed slowly over a short to long period of time. In addition, whey protein reduces the difficulty of drinking casein, which can be considered a demerit of casein, so those who have trouble drinking casein by itself should definitely try mixing the two.

Casein Protein is a Good Choice!

Casein protein can be broadly divided into ” casein micelles ” and ” caseinates. The features of these two types differ, so it is important to check them out when buying protein.

Casein micelles are best before bed!

Casein micelles, also called MPC (Milk Protein Concentrate), are casein proteins extracted from milk in a natural form by separating the casein through physical membrane processing. Because of its large molecular size, it takes time to digest and absorb, making it ideal for use before bedtime or when a meal cannot be consumed for a while.

If solubility is important, caseinates are the way to go!

Caseinate is a neutralized casein protein. Sodium caseinate and calcium caseinate are caseinates. Compared to casein micelles, caseinates have the advantage of being absorbed relatively quickly and dissolving easily in water because of their finer particles. They are also less expensive than casein micelles, but are often avoided in terms of flavor. It is recommended for mixing with whey or for those who want to try it out.
