What is it?

Micellar Casein is a dairy protein derived from milk and accounts for roughly 80% of the protein found within milk. Micellar Casein is undenatured casein that is available in its natural globular composition (known as a micelle). The group of milk proteins we usually refer to as casein are comprised of alpha casein, beta casein, gamma casein, delta casein, and kappa casein. A casein micelle is composed of all five of the alpha, beta, gamma, delta, and kappa caseins. If one eliminates, or changes, any one of the five caseins, the casein micelle is destroyed. Micellar Casein differs from other caseins / caseinates as it exists in its natural form and is more easily digested and assimilated by the body. Nevertheless non micellar caseins and/or caseinates have been exposed to acid and alkali processes during their formation in order to make them a lot more palatable to be used  food. As a result of these tough procedures they have a reduced level of bioactivity due to the natural micellar structure of the casein being irreparably destroyed which results in the protein becoming denatured / damaged.

What is it used for?

Normally, Micellar Casein has been used as a maintained release protein because of its inclination to gel in the small intestine and progressively release out over 6-7 hours. It is frequently labelled as an anti-catabolic protein because of its continual release properties. Nonetheless, it should also be pointed out that because of the continual release properties and the special bio-active micro-fractions within Micellar Casein it can also be regarded as a highly anabolic protein as well. The majority of weight lifters generally tend to use Micellar Casein prior to bed at night. Even so, Micellar Casein is also suitable as a standard purpose protein for daytime use as well. General purpose use of Micellar Casein subsequently results in better nitrogen storage for longer periods of time. This type of usage stimulates ongoing muscle protein synthesis through the regular release of critical muscle building and immune enhancing amino acids such as leucine, arginine and glutamine.

Who should use it?

Anyone seeking to preserve or enhance lean muscle mass. Persons on low calorie diets would as well do well to use Micellar Casein as it helps maintain satiety (feelings of fullness) for longer periods of time than whey or even soy protein.

How do you use it?

Add a serve to either water or milk in a shaker cup. Otherwise, it can be added to an existing whey protein blend for the purpose of extending its amino acid release rate.

Suggested intake times would be every 6 to 7 hours throughout the day and prior to bed at night. It is not advised that Micellar Casein be ingested instead of a rapid performing Whey Protein within the first 1-2 hours after resistance training.

How much should I use?

The same approach to dosage applies to Micellar Casein as any other protein source
