The Top 4 Benefits of Casein Proteins

Even though most athletes are quite familiar with protein supplements such as whey, not everyone is as familiar with casein proteins. This is a real shame, because casein has just as many benefits to offer as its relative whey protein. To learn more about casein proteins and the benefits they could deliver, please discover the top four benefits of casein proteins below!

1.    Casein Proteins Maintain Your Muscle Mass

One of the greatest benefits associated with casein protein is its ability to hold onto muscle mass, especially for athletes who find themselves on a calorie-controlled diet. When you limit the number of calories you eat on a daily basis, you are more prone to muscle loss, because calories are needed to supply the energy your body needs. If there are insufficient calories to do that, your body will turn to other things to get energy, for example stored body tissues such as muscle.

A study executed by researchers in Boston showed the increase of lean muscle mass and fat loss in test subjects taking casein proteins or whey proteins. All of the participants were also subjected to a calorie-controlled diet and resistance training. At the end of the study, both groups experienced a loss of fat and an increase in lean muscle mass, but the group consuming casein proteins lost more fat compared to those using whey protein.

During the study in Boston, test subjects from both groups increased their protein intake with 1.5 per kilogram of body weight per day, so this must be considered if you are basing your decision on the results of this particular study. At the end of the day, results from protein supplements will not show if you are not meeting your suggested daily protein intake for the day. Therefore, it could be a good idea to have a look at your diet in general if you are struggling to build muscle mass. If you have trouble building muscle, you could have a shortage of protein in your diet to begin with, so this must be addressed before supplementing with casein protein to obtain better results.

2.    Better for Weight Loss

Casein protein supplements tend to have high levels of calcium and this fact could prove beneficial to athletes looking to lose weight. A study executed by the International Journal of Obesity showed the effectiveness of calcium for weight loss, more specifically by combining a high calcium intake and a normal protein intake.

The results of the study showed that test subjects combining a high and normal protein intake experienced a bigger decrease in fat, but also used their energy more efficiently. These results were evaluated based on a comparison with test subjects on a low calcium diet; this once again proved that weight loss can be stimulated with a simple casein protein supplement addition to your diet.

In addition to the benefits of a high calcium intake, the study executed by the International Journal of Obesity also showed the advantages of combining calcium, protein rich foods and supplements during a weight loss program. If someone has problems adding both these nutrients to their diet, it can be a good idea to use a casein supplement and add it to their diet plan. Casein protein contains both proteins and calcium, so a shake a day can keep your progress going.

3.    Promotes Colon Health

Athletes who experienced problems with their colon in the past, may benefit from adding casein protein to their diet. A recent study executed in Australia, indicated that certain types of proteins can provide consumers with a number of health benefits.

Amongst the results that were obtained during the Australian study, researchers found that dairy proteins are especially beneficial for colon health, especially compared to other sources of protein such as meat and soy.

4.    Higher Quality Protein

Another benefit you will be able to obtain from casein protein supplements is high quality protein. In order to be healthy, you need the right amount of protein each day. When you use a high quality protein instead of a low quality protein, you are more likely to meet your daily protein requirements, which is why a casein protein could be beneficial for athletes who tend to struggle with a protein shortage.

In order to back up the theory of casein protein being a high quality protein, the Journal of Nutrition executed a study and compared a good casein supplement with a soy supplement. Results obtained from the study indicated that casein protein offers better quality protein than the soy variant, making casein an excellent source of protein to add to your diet.

Considering the high quality of casein protein, vegetarians may also get a lot of benefit from it. While most people get a lot of protein from foods such as dairy and meats, vegetarians cannot obtain meat proteins because meat is not a part of their diet. Therefore, vegetarians adding casein to their diet can get the protein their body needs without having to eat any meat.


When you use protein supplements on a regular basis, and have limited your supply to whey protein in the past, be sure to add a casein protein supplement to your shopping list next time you order your supplements. Even though casein protein is not the best protein to take after training because of its slower digestion rate, it can be a good supplement at bedtime or with your meal, more specifically to ensure you get all the protein you need for maximum muscle growth and muscle mass maintenance.
