Casein: What it is, Benefits and Properties

Casein is a name that’s becoming increasingly popular among the population, especially among those who exercise and take care of their bodies. It’s a high-biological-value protein found in milk and some of its derivatives, fermented products such as yogurt and cheese.

For example, milk contains approximately 3.5% protein, and 80% is casein and only 20% is whey protein. This is necessary for the absorption of calcium and phosphate into the intestine. In addition, it contains essential amino acids, a high percentage of glutamine, which is attributed beneficial properties for the immune system and muscles. Hence, the interest that many athletes have in it.

What is the function of casein?

Casein has a slower absorption if we compare it, for example, whey protein. Therefore, its assimilation is continuous and progressive, in addition to providing proteins gradually.

This protein appears in multiple food supplements used to reinforce the contribution of strength training and/or bodybuilding. These professionals use it in order to meet their needs, but they also take it preventively. Its consumption can prevent the appearance of muscle catabolism, that is, the destruction of the protein of muscle tissue.

Casein can be taken directly, but we also find it in another series of products, which can facilitate their intake. It is the basis of protein supplements, smoothies, bars and meal replacement products used by athletes.

This protein is not used only in the sporting field. Its emulsifying properties cause it to be used in the dairy sector to make cheese. It can also be found in the meat industry, for example.

Allergies

This is a protein we found in products like milk. Therefore, people intolerant to lactose or allergic to cow’s milk should be careful. Depending on the level of allergy, excessive or too continuous intake of protein supplements can damage areas such as the kidneys or liver.

When to take casein?

Casein has better results if consumed at night, as it is a slow-absorbing protein. However, we can also consume it at any time of the day, although it will not have the same effects as if you consume it at night, before going to sleep.
