What Is Casein?

When you enter the world of protein supplements, you will hear the name of certain protein supplements more than others. One of the better known protein supplements on the market today is casein protein, which could be very effective for muscle growth and repair. To learn more about the specific benefits of casein proteins, and figure out if they could be useful for you, please read our information below.

Better Muscle Maintenance

Losing muscle mass can be a big problem if you are limiting the number of calories you eat on a daily basis. In order to maintain muscle mass, you will need the right number of calories, since your muscles need a specific amount of energy during the day. If those calories are missing, your body has to find other ways to find the energy it needs. In these cases, the body can start to use and break down muscle to get that energy.

To examine the effects of casein proteins on the maintenance of lean muscle mass and fat loss, a study was executed at the University of Boston. During the study, researchers monitored changes in lean muscle mass and fat. Test subjects participating in this study were divided into two groups. One group was supplemented with casein proteins, while the second group was given whey proteins.

The results of the study showed that both groups of test subjects lost a considerable amount of fat. However, the group using casein proteins showed a greater loss of fat and a bigger increase in strength in certain parts of the body; this included the chest, shoulders and legs.

Test subjects on casein proteins showed another remarkable improvement, more specifically a greater increase in lean muscle mass compared to test subjects using whey proteins. These results would indicate that casein proteins are more effective at maintaining lean muscle mass.

Weight Loss Benefits

Some athletes may start to use casein protein to lose some weight, since casein contains high levels of the mineral calcium. Calcium has shown to have numerous benefits for fat loss, so if you are dealing with persistent fat deposits, casein protein may provide you with the extra leverage you need.

Many athletes are afraid to use dairy products for weight loss, mainly because there are a lot of myths surrounding dairy products in relation to the loss of fat. To disprove the myth that dairy products could hinder weight loss results, a study was executed by the International Journal of Obesity. During the study, test subjects were required to combine calcium with their normal protein intake. The results were definitely surprising, because test subjects showed an increase in fat and energy excretion compared to their original readings.

Might Promote Better Digestion

One of the benefits you would not necessarily associate with dairy products is better digestion, at least according to a recent study in Australia. During this study, several researchers looked into the effects of specific types of protein; this includes casein protein, meat protein and soy protein. The results showed that dairy-based proteins, such as casein, were more beneficial than meat or soy proteins.

Additional Nutritional Value

Still, one of the biggest benefits casein proteins can deliver is a balanced and nutritious diet. When you add regular protein-rich foods to your diet, you will still get the protein, but not in the amount of the quality that a protein supplement such as casein protein can deliver.

Casein Proteins at Nutrients Direct

If you have decided to add a casein supplement to your diet, Nutrients Direct can provide you with the right one. Our range can provide athletes with numerous casein proteins, as well as other proteins such as whey, soy, rice, pea an and egg protein.

Calcium Caseinate

Calcium Caseinate is a great dairy-based supplement for enhanced sports performance and muscle building. As is the case for all casein proteins, Calcium Caseinate is classified as a slow-release protein with high levels of amino acids. Due to the extraordinary time-release qualities of Calcium Caseinate, as well as a high amino acid content, athletes can use this supplement between training sessions or before bedtime.

Our Calcium Caseinate is currently available in three flavours, more specifically natural, chocolate and vanilla. Customers can also save some money by purchasing a bigger supply of this supplement, since Calcium Caseinate is available for purchase in packs of 1 kilogram, 2 kilograms, 5 kilograms and 10 kilograms.

Micellar Casein

When you do not only need a casein supplement to increase your sports performance and muscle building, but also to increase your endurance, you might benefit more from our Micellar Casein supplement.

Micellar Casein is considered to be the purest form of casein on the market today and is accompanied by the same slow-release qualities all casein proteins are known for. To provide this pure form of casein, the substance is pulled through an ultrafiltration process and put under a low temperature. The result is an effective casein supplement suitable for those with fast metabolisms.

Similar to Calcium Caseinate, Micellar Casein is available in three delicious flavours: natural, chocolate and vanilla. Athletes can also acquire bigger packs of the supplement at Nutrients Direct, so you will not run the risk of running out.


Casein proteins can be very effective for muscle building, endurance enhancement and better sports performance, providing you know how you should use this protein supplement. Casein should be used by athletes with faster metabolisms, who do not get much benefit out of fast absorbing protein powders, or athletes who want to feed their muscles with valuable amino acids while they sleep.

If Casein protein is not really what you are looking for, no need to despair because there are countless protein supplements to choose from at Nutrients Direct. Be sure to have a look at our range of whey protein, egg protein, soy protein, bovine colostrum and much more. We are sure you will find something that matches your training routine.
