What Is Micellar Casein Protein?

Author: Nicole Adler   Date Posted: 1 December 2016 

Athletes looking to add extra protein to their diet will get numerous choices in our range of Australian online supplements. One of these options is micellar casein protein, a specific protein powder in our range of Australian online supplements. To learn more about this casein supplement, please read our information below.

Where Is Micellar Casein Protein Powder Obtained from?

Micellar casein is a dairy protein obtained from cow’s milk. In milk, there are two different types of proteins. These proteins are casein and whey, with casein making up approximately 80% of the total protein content in milk.

Now you know where casein from our range of Australian online supplements is obtained, it is time to explain the term micellar. The term micellar refers to the fact that casein proteins naturally appear in “micelles” form when in liquid. Therefore, micellar casein’s global structure is referred to as micelle.

All casein protein powders inside our range of Australian online supplements consists of smaller groups of proteins; this includes alpha, beta, gamma, delta and kappa casein. To have a complete casein protein powder, all five groups must be present, because if one of these groups is missing, the casein will be destroyed.

Naturally, casein protein is not only used in our range of Australian online supplements, but also in regular food. Therefore, manufacturers may subject casein protein to certain acid and alkali processes, which make the proteins taste better in foods. However, these processes can lower the bioavailability of casein, as well as denature or damage the protein.

What Are the Characteristics of Micellar Casein Protein Powder?

Micellar casein protein powder has a high biological value, which means that a lot of the protein inside this casein protein powder is absorbed and used by our body. Once the casein enters the stomach, it forms a clump. Because of this, casein is digested a lot slower than other proteins, for example whey protein.

Due to the slower digestion rate of micellar casein protein, this protein is mainly suitable for periods where no food will be consumed. For example, athletes can take a casein protein supplement right before bedtime, so their body will be fuelled with protein during the night.

Research has shown that whey protein can only deliver branched chain amino acids for four hours after ingesting it. After this time, branched chain amino acids are no longer supplied. Therefore, casein protein can promote muscle growth and repair during the night.

There are some differences between the amino acid profile of casein protein and whey protein, even though both amino acid profiles are quite similar. However, casein protein does contain more leucine, which is provided continuously for seven hours after consuming the supplement.

Which Athletes Get the Most Benefit from Micellar Casein Protein?

Micellar casein is best used by athletes as a post-workout supplement, since casein can provide valuable protein for a longer period than whey protein. It can be used throughout the day, but is especially useful before bedtime. When taken before bed, micellar casein could keep the body in an anabolic, muscle-building state.

The use of micellar casein is also advised to maintain lean muscle mass. Of course, micellar casein is also good for athletes trying to lose weight, because casein protein can help you feel fuller longer. Even though whey and soy protein can deliver a similar effect, casein protein can give that satiety feeling longer.

Which Casein Protein Supplements Are Available at Nutrients Direct?

Nutrients Direct offers two types of casein protein, more specifically Calcium Caseinate and Micellar Casein. To learn more about these specific protein supplements from Nutrients Direct, please read our information below.

Calcium Caseinate

Calcium Caseinate is a supplement that is often used to increase sports performance and muscle building abilities. The protein powder contains many amino acids, which have unique time release properties, ensuring that the body stays fuelled over a longer period.

Many athletes incorporate Calcium Caseinate into their diet, because this supplement has strong anti-catabolic properties, subsequently leaving the body in an anabolic (or muscle building) state. Therefore, using Calcium Caseinate can have an amazing effect on your muscle growth and muscle maintenance.

Micellar Casein

Micellar Casein is the second casein supplement that may contribute towards increased muscle performance, muscle building and endurance. The protein powder is made with a low temperature ultrafiltration process, ensuring the purest form of casein that is still easy to digest. However, easy digestion does not mean that Micellar Casein cannot provide a long-term amino acid supply, because this supplement can keep your body fuelled with valuable protein for approximately seven hours.

What Other Protein Supplements Are Available at Nutrients Direct?

Slow-release protein supplements are not the only options available to you at Nutrients Direct, because we also offer quick and intermediate-release protein supplements. This includes supplements such as Hydrolysed Whey Protein Isolate, Whey Protein Concentrate and Egg Protein.

Nutrients Direct also offers protein supplements that do not contain any animal protein, but are solely made with plant-based proteins. Good examples of such protein supplements are Pea Protein Isolate, Rice Protein Isolate and Soy Protein Isolate. None of these options contain animal protein, so they are all suitable for athletes following a vegan diet.

Some of the protein supplements in our range are suitable for athletes suffering from lactose intolerance or gluten allergies; this is specifically mentioned on the product description page of the protein supplement.
