  • Casein powder is available in different forms. Basically, you can choose between micellar casein, caseinate and casein hydrolysate. These three types differ to some extent in their properties and composition.
  • Casein powder is usually mixed with a liquid and then drunk as a shake. Most preparations are available in different flavours.

The Best Casein Powder: Our Picks

Guide: Questions you should ask yourself before buying casein powder

What is casein?

Casein is a protein, more precisely a milk protein. It ensures that fat loss is promoted. At the same time, the protein maintains muscle mass in the body, which is why it is used in most cases during diets or training sessions.

Like any protein, casein is a protein and consists of amino acids. Our body cells are therefore dependent on proteins so that they can function perfectly.

Proteins are consumed through food. In some cases, the intake is not sufficient for certain proteins, so supplementation with additives can be useful.

Casein is absorbed and metabolised slowly by the body. This provides the body with important muscle building blocks for 6-8 hours, which counteracts muscle breakdown. As a rule, the milk protein is therefore taken before going to bed.

Casein itself has a biological value of 77, which indicates the efficiency with which the protein works in the body. It seems low compared to other proteins, but due to its slow digestibility, it provides a continuous supply of protein, for example overnight.

What is Whey in contrast to Casein?

Whey is the other milk protein, which in many cases is also called whey protein. Like casein, it is derived from milk, yet the two differ in their properties. In some products, the two proteins are used together, but they are also available separately.

Whey has a valence of 110 and, unlike casein, works much faster in the body. This is why the protein is usually used after training for muscle recovery.

Whey and casein are both important sources of amino acids, but differ essentially in their timing of intake. In addition, whey essentially promotes muscle building, while casein mainly ensures that muscles are not broken down.

When it comes to the question of which of the two proteins suits you better, the timing of intake is the most important factor:

Protein When to take it
Whey Directly after training, as the amino acids are directly available to the muscles
Casein Directly after going to bed, so that the body remains supplied with amino acids overnight

What does casein protein do?

The main effect of protein is to prevent muscle breakdown. After ingestion, it enters the stomach. There the protein absorbs a lot of moisture so that it clumps together. This means that it takes several hours for it to be digested.

This constant supply of small amounts of protein ultimately prevents muscle breakdown. The use of milk protein is particularly useful in phases when training is not taking place, for example overnight.

Casein protein also contains a lot of glutamine, especially glutamic acid. This has other health-promoting properties, such as strengthening the immune system.

Casein also contains many branched-chain amino acids, so-called BCAAs (Branched Chain Amino Acids), which are essential in the muscle-building process.

How can I use casein powder?

Milk protein can be used in many ways. Since it is usually available as a water-soluble powder, casein protein can also be optimally incorporated into your own eating habits.

How much powder you should take per dose depends strongly on the intended use. For example, 10-20 g is sufficient before or after training, while you should increase the dose to 30-40 g before going to bed. You can find more detailed information on the dosage of the individual preparations in the respective product description.

Basically, you can use casein powder for three different aspects:

  • Casein as a dietary supplement
  • Casein for sports
  • Casein for weight loss

Especially in connection with overweight, the intake of casein can be beneficial. Triglyceride levels that are above normal in connection with diabetes, obesity and kidney disease can be lowered. (1, 2)

Casein can be used as a simple food supplement if the body does not get enough casein from the actual food intake. In general, it can be useful to consult a doctor or pharmacist before taking a dietary supplement.

Casein in sports can be particularly useful in the muscle-building process. Especially by using it overnight, you can prevent the muscle mass you have gained from degrading again.

You should bear in mind that casein powder can only help you optimally during training if it is used correctly. That is why it is never a bad idea to consult a specialist. You can get individual advice from your trainer, sports instructor, doctor or another specialist.

Casein is often usedas a meal replacement in the course of diets. Since casein is digested slowly, you get a feeling of satiety after taking it, which can counteract binge eating.

It is also important to get individual advice. Not every body functions in the same way and is subject to the same conditions. In addition, you should consider that several factors are necessary for successful weight loss and that it is not sufficient to take only casein powder.

How much does casein powder cost?

Depending on the form of casein and how much you buy at once, the price can vary. You can get casein as a powder, but also in tablet or capsule form.

Many manufacturers sell larger quantities of casein and therefore quote the price per kilogram. You can use this to compare the individual products with each other. You can also get your casein in smaller quantities.

For one kilogram of casein you will spend an average of 18-40 GBP.

This price can vary greatly between different manufacturers, which is why it is worth comparing them on online platforms. However, you should always keep an eye on the quality.

Can casein powder be harmful?

Casein powder is generally not harmful to the body. You only have to be careful if you have a so-called casein sensitivity. In this case you have problems digesting the protein casein. This can cause similar damage to gluten intolerance.

In principle, it is always worth talking to your family doctor before taking the product to make sure that it really cannot cause any damage to your body.

If you are lactose intolerant, there are now also casein preparations without lactose that can be used in such cases. However, other proteins that are not derived from milk are usually recommended. Your specialist can also give you more individual information in these cases.

Decision: What types of casein powder are there and which is right for you?

Casein powder is available in different varieties. Depending on what you want to use the casein for, a different type might be suitable for you. As a rule, you can get casein as a powder or in tablet or capsule form.

Basically, you can choose between these three types:

  • Micellar casein
  • Calcium caseinate
  • Casein Hydrolysate
  • Casein in a shake

In the following, we explain the different types and their respective advantages and disadvantages. We want to help you find the best casein powder for you.

What are the advantages and disadvantages of micellar casein?

Micellar casein is not a pure form, but consists of 80% casein and 20% whey. Nevertheless, it is described as the highest-quality casein preparation because the milk protein is left in its natural structure.

Advantages
  • Gentle processing makes it particularly high quality
  • Natural form of milk protein
  • Many products available with production in Germany
  • Can partly also be used with intolerances
Disadvantages
  • Contains not only casein but also Whey
  • Many products contain sweeteners
  • Not all flavours are edible according to experience

In the production of micellar casein, the protein is very gently extracted from the milk. This means that no important amino acids can be lost. This naturally also has a positive effect on the overall quality of the micellar powder.

Micellar casein is often found in products from America, but increasingly also in German products. On larger online platforms you can also find micellar powder from regional production.

For the most part, you can also use micellar casein with intolerances, such as lactose intolerance. However, in such cases you should consult a doctor or pharmacist before taking the product.

What distinguishes calcium caseinate and what are its advantages and disadvantages?

This is the purest form of casein. Here, the casein itself and its amino acids are separated from the whey and released. As a result, the protein has a lower fat and carbohydrate content.

The best use of this type is in diets. Here you can take the protein as a supplement before going to bed. The protein thus acts as a food substitute. Of course, you can also use it during training to build muscle.

Advantages
  • Pure casein
  • Particularly suitable for weight loss
  • Most preparations are easily soluble, even in water
  • Good preparations are on the Cologne List
  • Production mostly within Europe
Disadvantages
  • Many products are nevertheless on the market as mixtures
  • Often not available allergen-free
  • Percentage of protein varies depending on flavour

Calcium caseinate powders are also offered in various flavours. Here you should pay attention to the composition of the flavourings and the protein itself. Depending on the flavour, the percentage of pure protein can vary.

To check the quality of the preparation, you can look for any seals. One such seal that says a lot about sports supplements is, for example, the Cologne List.

What distinguishes casein hydrolysate and what are its advantages and disadvantages?

Casein hydrolysate is absorbed by the metabolism much faster than the other two types. This is due to the chemical composition of the protein. The manufacturers not only absorb the protein more quickly, but also more gently.

Roughly speaking, the chemical process of hydrolysis of casein can be described like this: Casein is split with water during hydrolysis. In the process, a water atom is added to the casein and casein hydrolysate is produced.

Advantages
  • Faster processing in the body
  • Very reduced allergen activity
  • Gentler absorption of the protein
Disadvantages
  • Can only be used as a food supplement and not as a food substitute
  • A bitter taste can occur with a high degree of hydrolysis
  • More expensive in terms of price

This type of casein, because of its faster metabolism, is used more as a food supplement than a complete meal replacement. It is particularly suitable for allergen intolerances, as it has greatly reduced allergen activity due to hydrolysis.

Important in connection with casein hydrolysate is the degree of hydrolysis. It indicates the percentage of peptide bonds (fatty acid compounds) of the protein that have been cleaved. The more, the better.

The disadvantage is that as the degree of hydrolysis of casein increases, an unpleasant bitterness appears. This side effect can also be found in the later powders.

Buying criteria: You can compare and evaluate casein powders based on these factors

Have you decided to buy casein powder for your own purposes? Then we would like to show you some criteria below to make your purchase easier.

Based on these criteria, you can then easily decide for yourself whether the respective casein powder is suitable for you or not.

In summary, these are the following criteria:

  • Ingredients and ingredients
  • Intended use
  • Solubility
  • Allergens
  • Flavour
  • Country of origin

In the following, you can read about the respective criteria and find out why it makes sense for you to purchase a product based on the criteria or not.

Ingredients and contents

Casein powder itself can have different compositions, which is why there are different types. In addition, the ingredients and contents can also differ greatly.

For example, some preparations may contain additives that you do not actually want. However, it is often not easy to filter out exactly these substances from the list of ingredients.

Such additives can be, for example, colourings, sweeteners, flavourings, table salt, extra calories or thickeners. They are added to guarantee the optimal quality of the product.

In general, you should use products with as few additives as possible. If you are unsure about the chemical terms, it is always a good idea to consult a professional. This way you can clarify individually what is actually in your casein preparation.

Intended use

Before you buy a casein supplement, you should think about what exactly you want to use it for. The two most common uses are for training and for weight loss. You can also use casein as a dietary supplement.

Intended use Suitable preparation
Sport Micellar casein
Diet Calcium caseinate
Food supplement Casein hydrolysate

If you use casein for sports, you should get a casein preparation that is specifically designed for this purpose. Micellar casein is particularly suitable for this purpose because, in combination with whey, it helps to build muscle and, above all, counteracts muscle breakdown. In addition to strength, hyperthropy values of the muscles can also be increased. (3)

When dieting and losing weight, it makes sense to use calcium caseinate. This is the purest form of casein and can be used as a meal replacement. However, you should always bear in mind that successful weight loss requires more than just a powder.

Casein hydrolysate is suitable foruse as a dietary supplement, as it enters the bloodstream particularly quickly and gently. However, since casein is only used as a food supplement, it cannot replace a healthy and balanced diet.

Food intake can be reduced with the intake of casein. (4) Whey protein may make more sense in connection with diets. In direct comparison to casein, a faster feeling of satiety can occur. (5)

In direct comparison, a reduction in blood and cholesterol levels as well as insulin levels can also be brought about. (6)

Solubility

The main use of casein powder is in protein shakes. To ensure that this shake is a success, you should find out about the solubility of the product beforehand. You don't want to end up with a lumpy mixture after the purchase.

The solubility also depends on the substance in which you want to dissolve the casein powder. The liquid in which casein powder is most difficult to dissolve is water.

via GIPHY

Many suppliers advertise good solubility on the packaging and in the descriptions. The presence of this information is already good. However, you should check the reviews and comments, especially on online platforms, to make sure it is correct.

In the drugstore, you can ask the specialist staff directly or search for the product online. There you will usually also find the experiences of other users.

Allergens

Casein, like whey protein, is derived from milk. Therefore, it is not advisable to use it if you are lactose intolerant. Nevertheless, there are many products that also offer casein preparations for allergen intolerances.

In addition to lactose, other allergens such as gluten or soy may also be present. If you have problems with allergen intolerances, you should definitely check the allergen list of the product beforehand.

You can get individual advice on allergens from your family doctor or your local pharmacy.

Did you know that casein intolerance can be reversed through an adapted diet?

If you are diagnosed with casein intolerance by means of a blood test, it is recommended that you completely avoid animal dairy products for a period of 2-3 months. This will allow your intestinal mucosa to regenerate and you can slowly integrate milk back into your diet.

Flavour

Before buying a casein preparation, you should be aware that almost all powders contain flavourings. To make the shake taste good, manufacturers create a wide variety of flavours.

The choice depends mainly on your own preferences. In addition, it is advisable to check reviews and experiences of other buyers. If a flavour is very unpopular or many flavours of a manufacturer are boycotted, it is very likely that you will not like them either.

In many cases, however, you only find out if you like a flavour or not when you try it. So if you are buying a flavour that you don't know or are unsure about, it is worth buying a smaller quantity first.

Country of origin

Casein preparations are produced in many different countries and sold in Europe. Especially through online trade, it can often happen that you are offered products from distant countries.

These do not necessarily have to be the worse ones. However, with products from Germany you can be more sure about the quality controls of the preparations, such as the Cologne List.

In addition, by buying regional products, you support the local economy and can protect the environment through shorter transport times. Don't forget that you can buy casein powder not only on the internet, but also in the nearest drugstore or pharmacy.

Trivia: Facts worth knowing about casein powder

When should casein be taken?

Casein usually takes a long time to be metabolised. The ideal time to take it usually depends on your intended use.

Thus, many determine the perfect time to take it before going to bed. In this way, the body also receives a supply of protein during an actual resting phase. It also stimulates muscle protein synthesis. (7) Taking it in the morning or evening does not necessarily improve body composition (8)

If you use casein powder for training purposes, the right time to take it can also be after training. At this time, the loss of muscle mass is prevented.

Although the increase in muscle synthesis is similar for casein and whey, the latter increases serum insulin levels and accelerates fat burning. (9) In this context, higher strength gains are also possible. (10)

If you are still unsure, you should ask your trainer, nutritionist or pharmacist for advice.

How long should casein be taken?

Basically, you can take casein for as long as your body needs it for muscle breakdown or fat burning. It is more important that you take the supplement regularly. Only with regular use can the protein have a positive effect.

Regular use of casein powder is particularly worthwhile in the area of strength sports. If you use the protein for weight loss purposes, it is sufficient to take the protein for the duration of your diet.

Did you know that casein can supply your body with amino acids for up to 7 hours due to its slower absorption?

This can significantly reduce the rate of protein breakdown, which in turn is an immense advantage when you consider that building muscle is the result of the equation protein synthesis minus protein breakdown.

What foods contain casein?

Basically, casein is present in all dairy products and types of milk. It is difficult to say how high the content is in the respective products, as the content can fluctuate. Basically, however, the more proteins, the more casein is contained.

Cheese and quark contain the most casein, but so do drinking milk, buttermilk, sour milk and yoghurt.

Can casein also be mixed with whey?

The two proteins are found in mixed form in micellar casein. They are also together in their natural form in milk and are only separated during processing.

Therefore, mixing the two is not problematic. However, if you are taking the proteins for specific purposes, the respective dosage of the two is very important.

In addition, you should also consider that the two proteins have different properties. If you want to use only one or the other, you should keep the two proteins separate.

With which liquid do I prepare a casein shake?

As a rule, casein powder is intended to be used to prepare a shake. You can dose the powder individually in your own shake. Many casein products therefore have the word 'shake' in the title. However, it is usually just a powder that has to be mixed first.

You can prepare your shake with a variety of liquids, the most common of which are probably water or milk. In general, any drinkable liquid can be used as a solvent for casein, but which one you choose is ultimately a question of the additional calories.

If you want to slow down the metabolism of casein powder even more, you can also add 10-20 ml of linseed oil. However, this may change the taste.

Of course, you can also mix your casein powder with other foods such as quark or yoghurt if you don't always want to make a shake.
