100% Grass-Fed Casein by Transparent Labs leads this ranking of the best micellar casein protein by the total number of points. One serving contains 25 grams of high-quality protein, 4 grams of carbohydrates (one of which is dietary fiber) and only 0.5 grams of fat per serving.
Note that of all the products in this ranking, Transparent Labs contains one of the highest amounts of calcium per serving, at a whopping 727 mg! It's a great protein with a great texture and flavor that can be used both for mixing protein shakes and adding to baking as a thickener. Also, pay attention to the small amount of additional ingredients besides casein itself. If you avoid sucralose but don't mind stevia extract with its distinctive aftertaste, you might really like it.

The price per serving is very affordable, and you can also choose one of two packaging options - a smaller or a larger jar. Overall, this is a very good and balanced product that scored high and took its place in the top five. For the best ratio of protein, lowest carbs and sodium, go for the unflavored version.
Positives:
Versatile macronutrients breakdown
Zero to 0.5 g of fat per serving
High amount of calcium per serving
One of the lowest prices per serving

For those looking for the best casein protein for weight loss, Naked Casein in the unflavored version is the best option, because it does not contain any macronutrients other than protein. Not one gram of fat or carbohydrates and 110 calories per serving! Also, this product contains one of the lowest amounts of sodium that can be found in protein supplements. Only 20 mg per serving for an unflavored version.
Also, if you are hunting for a clean casein protein, please note that this product does not contain any "other" ingredients other than pure micellar casein. However, again, this only applies to the unflavored version.

This product is also available in Vanilla and Chocolate flavors, but they contain added sugar, so the calories per serving are 130 and 150 kcal, respectively. They also have a significantly worse Protein-by-Weight Ratio compared to the unflavored version, which has one of the best scores among all products in this rating at 87%. Note that Naked received the highest score in the "Ingredients Breakdown" category specifically for the unflavored version.
Positives:

This product deserves to be included in every best casein protein reviews, because Promix Casein in an unflavored version is one of the best value for money offers on the market. Let's face it, when one serving contains 25 grams of high-quality protein, 0 grams of carbs and fat, and costs just over a dollar, it's hard to argue against it.
In fact, this product is very similar to the previous one, as the flavored versions have a worse macronutrient composition due to the presence of added sugar. At the same time, the unflavored version also has one of the best Protein-by-Weight Ratios, only 1 percent behind Naked. Also, this product in the unflavored version is one of the best casein protein for weight loss, because it has only 105 kcal per serving, which comes entirely from micellar casein.

ALLMAX CaseinFX is micellar casein from a Canadian brand that certifies many of its products through Informed Choice. This is a very high-quality product with a relatively high calorie content of one portion (130-135 kcal), so it will be good for people who are fighting for every kilogram of weight gained.

One serving also contains only 30 mg of sodium and up to 600 mg of calcium, which is a nice bonus in addition to the casein itself. You have 2 flavors to choose from: Chocolate and Vanilla, although some users did not rate the taste very highly. I would also like a bigger package, because 27 servings are not enough even for one month if you use one serving every day.
Positives:

If you are concerned about the artificial sweeteners sucralose and the acesulfame potassium, Dymatize may not be right for you. Although just so you know, based on the FDA's estimates, to exceed safe dosages of artificial sweeteners, we would need to consume more than 20 packets servings.
It is worth noting a sufficient number of reviews about the strange aftertaste and too thick texture.

The next is NOW Foods Micellar Casein from the brand from way back in 1968. If you need a high quality and affordable casein protein before bed, this could be it. Please note that this product contains no natural or artificial sweeteners and is therefore presented in unsweetened powder form. The only additional ingredient is sunflower lecithin, which helps to get a pleasant mouthfeel. This product is certified by Informed Sport and contains a low amount of sodium per serving.
If you can't take protein supplements without flavor, this product may not be for you. In fact, this protein has quite a large number of reviews about it's not the best taste. It was for the "Taste" category that it received a score of 8.5 and the overall 12th position in this review.
It is worth giving you some clarification on the amount of protein per serving compared to other protein supplements. One serving of this product contains only 19 g of protein, because the weight of the serving itself is only 24 grams. So keep in mind that to get 24-25 g of protein, you will need to increase the serving of the powder to about 31-32 g. In this case, the actual number of servings will not be 34 servings (as suggested by the manufacturer), but approximately 26 servings. Therefore, in order to get 24-25 g of protein, the cost of a portion increases from $1.18 to $1.54.
Positives:
Good protein-by-weight ratio
Versatile macro breakdown

Despite its penultimate position in this ranking, Nutricost Casein Protein is still a very good product that deserves to be on the list of the best. There are Chocolate and Vanilla flavors on display, as well as an unflavored version with a good macronutrient composition.
However, note that the highest protein-by-weight ratio is in the unflavored version (80%), which contains only sunflower lecithin in addition to the micellar casein itself. Also, the unflavored version has the largest number of servings and the lowest cost per serving, which is worth considering for people who are trying to optimize their spending as much as possible.

Ultimate Nutrition PROSTAR® is a mixture of micellar and hydrolyzed casein, the latter of which is casein that has been broken down into smaller peptides. However, it is not known whether the mixture of these two sources of casein provides any significant advantages in terms of endpoints (building muscle mass, strength gains etc).
Regardless of the chosen flavor, a serving contains 24 g of protein, 0 to 1 fat and 3-5 g of carbohydrates. There are 3 flavors to choose from: Chocolate Creme, Strawberry and Vanilla Creme, each available in 27 or 69 serving packs. This product is low in sodium and has a very affordable price tag, but may have some texture issues and not the best taste.
Positives:
Low price per serving
Available in a package of 69 servings

Due to the presence of hydrolyzed casein, it may have a bitter taste
Contains a mix of artificial sweeteners (if that's important to you)
What Is Casein Protein Powder?
Casein is the predominant milk protein, making up to 80% of the total protein in milk. The remaining 20% are whey proteins. Casein powder is actually the dried casein part of milk protein, which is made from skim milk. It is a slow-digesting protein source which is why it is called slow release protein. A separate advantage of this type of protein is a very high amount of calcium.
It has high biological value and a high concentration of the most anabolic amino acid leucine (however, whey protein contains more leucine).
Pros and Cons of Casein Protein Powder
To better understand the characteristics of casein, let's briefly summarize its advantages and disadvantages.
Positives:
High biological value and digestibility
Due to slow digestion, it may be best suited for periods when you cannot eat for many hours in a row (for example, before a long trip or a long work meeting)
It can well contribute to better maintenance of muscle mass in conditions of calorie deficit
Can be a great snack before bed
Can help maintain a feeling of satiety during weight loss
Great for adding to baked goods because it can act as a thickener and can also improve texture
Good for those who prefer thicker texture of protein powder
Contains the highest amount of calcium of any protein supplement
Could be better:
Not the best choice for a pre-workout snack right before a training session
If you don't like the thick texture of protein shakes, casein may not be for you
Not suitable for people with allergies to milk proteins (together with whey and milk protein)
Casein vs Other Protein Powders
1. Whey Protein
In general, casein and whey protein supplements contain the same amount of protein, carbohydrates, and fat per serving, as well as the same amount of sodium. Also, they are equivalent in terms of calories and cost per serving. However, you need to compare individual supplements to see the differences.
Compared to whey protein powders, casein has some advantages and disadvantages.
Positives:
Contains much more calcium per serving (on average, 500-650 mg from a serving of casein versus 100-150 mg from whey)
Has thicker texture
May be better suited for making protein puddings or smoothies
Great for baking as it can act as a thickener
Could be better:
Contains less BCAA (including leucine) than whey protein
Whey protein is much better for a pre-workout snack
2. Milk Protein
Milk proteins are a mixture of casein and whey protein, which is high in calcium but still less than an isolated casein supplement. Casein and milk protein are similar in macronutrient composition per serving, however, milk protein has a lower average cost per serving, which is about $1.2-$1.5 versus $1.1-$2.
In fact, milk protein is the best whey casein blend that can provide all the benefits of both types of protein. This is an ideal combo for obtaining a high concentration of leucine from whey protein, as well as a steady feed of amino acids and a bigger portion of calcium from casein.
3. Egg White Protein
Egg white protein powder has a fairly similar BCAA and leucine composition to casein, as well as macronutrients per serving. The advantage of egg white powder is a much higher amount of potassium per serving (on average, it is 300-400 mg versus 100-200 mg).
Among the significant disadvantages - a very low amount of calcium (on average up to 60 mg per serving) and 2 times more sodium. Also keep in mind that egg white protein is an expensive supplement with an average cost of $1.9-$2 per serving (some exceptions offer $1.5-1.6 dollars per portion).
Egg white protein is a good alternative for people with allergies or intolerances to milk proteins, as well as for people with lactose intolerance. Conversely, egg protein powders are contraindicated in case of allergy to egg proteins.

4. Plant-Based Protein
Vegan protein supplements contain slightly less protein per serving (20-25 g) and more carbohydrates and fat then casein. At the same time, they contain very little calcium (20-60 mg per serving) and more sodium (with the exception of hemp protein, which usually contains from 0 to 15 mg of sodium).
Plant-based protein supplements contain a similar amount of potassium to casein, while having 2 advantages: they have significant amounts of fiber and a large amount of iron per serving (0-1 mg vs. 3-8 mg of iron for plant-based proteins).
It is worth considering that plant-based protein supplements are a rather diverse group, because some of their varieties (such as soy protein and the combination of pea + rice) have a better amino acid profile and anabolic potential than pea, rice or hemp proteins in isolated supplements.
In terms of average price per serving, plant-based protein powders are no different from casein protein supplement (although when you calculate the amount of protein per serving, plant-based ones are actually more expensive), with the exception of soy and hemp proteins, which cost around $1 per serving.
Although with sufficient consumption of the total daily amount of protein (at least 1.6 g / 1 kg of body weight and more) and even distribution (ie regular meals every 3-4 hours) plant-based proteins may not lose to proteins of animal origin in the context of changes in muscle mass, strength and other adaptive changes, in general, they have a lower essential amino acid content (including leucine), lower digestibility and lower anabolic potential than animal-based proteins (including casein).

Is Casein Powder Safe to Consume?
If you do not have an allergy to milk proteins, or intolerance to milk proteins, casein is safe for regular consumption. However, casein contains some lactose, so it may not be suitable for people with lactase deficiency. Keep in mind that if you are lactose intolerant, you may need time to experiment with different products from different brands. Unfortunately, we cannot predict how your gut will react to a particular product.
Also consider possible intolerances to "other" ingredients besides casein itself. If you experience indigestion after taking a particular casein supplement, it may not be right for you. In the absence of an absolute contraindication - an allergy to milk proteins - you can experiment with different caseins from different brands.
How Should I Take Casein Protein Powder for Best Results?
You can mix shakes and smoothies with casein, make puddings with it, add it to ice cream, oatmeal, or baking recipes, taking the full advantage of its texture and thickening properties! Experiment with recipes and find your perfect combinations.
For many years, it has been widely circulated that casein protein has exceptional benefits and effectiveness when consumed before bedtime. However, keep in mind that there is a lack of evidence confirming specific value of casein compared to other proteins. Rely on your preferences and convenience.
How to Find the Best Casein Protein Powder?
When choosing the best protein supplement, always keep in mind what you need the supplement for. It is needed to get a portion of protein! So pay attention to some key features.

Tip #1 – Look For Protein per Serving
Everything is very simple here. The more grams of protein in a serving, the better. The best protein powders have 24-30 g of protein per serving, and casein is no exception.
Tip #2 – Look for Carbs and Fat per Serving
The amount of carbs and fat can vary, so choose based on your goals. If your goal is to lose weight, it is better to choose a supplement with the least amount of carbohydrates and fats and the lowest calorie serving. If you are gaining muscle mass, then you will have a greater choice of products.
Tip #3 – Consider “Other” Ingredients
Consider possible or known intolerances or sensitivities to ingredients other than the protein itself. For example, stevia may cause bloating, gas and diarrhea in some people.
It is especially important to choose a casein supplement wisely for people with lactose intolerance. If your gut reacts violently to even a minimal amount of it, it is better to choose protein supplements that contain 0 g or the least amount of carbohydrates. This is especially true for protein supplements that have no added sugar, but still contain carbs. After all, if casein without added sugar contains carbohydrates, then it is lactose, which is the main carbohydrate in any dairy product without added sugar.

Tip #4 – Consider Brand Reputation and Third-Party Certification
In order to choose a high-quality, clean casein protein, do not try to save money by purchasing a supplement from an unknown manufacturer. Some products may contain high levels of heavy metals, other impurities and even banned substances.
Therefore, to minimize potential risks, it is better to choose a supplement from a well-known manufacturer, which also submits its products for laboratory testing by an independent third party. Examples of such organizations that are recognized in the world are NSF for Sport and Informed Choice / Informed Sport.
Don't worry too much about contamination of protein supplements, just take it as a precaution to minimize potential risks. However, for professional athletes undergoing doping control, it is always best to opt for supplements certified by a recognized third party.
FAQ
Is Casein Better Than Whey Protein?
Both whey protein and casein are high-quality protein sources with a complete set of essential amino acids and the highest concentration of leucine of any protein source. Whey powder is better suited as a pre- or around-workout snack, while casein can be ideal before a long period without being able to eat or as a bedtime snack. However, in the conditions of a mixed diet and sufficient consumption of high-quality protein per day, the battle of whey protein against casein is not of great importance. After all, you don't eat just whey protein or just casein and nothing else every day, do you?
Is It Ok to Take Whey Protein and Casein?
Absolutely, because in this case we can use the advantages of each of them. Remember that milk and other dairy products naturally contain both types of these proteins, so this question should be cleared automatically.
You can combine whey and casein powders in one shake or use them separately in different meals or snacks. However, if you want to combine them in one meal, you will have to experiment a bit to find the perfect ratio that works for you in terms of texture and taste.
Is Casein Harder to Digest Than Whey?
Since casein coagulates in the gut and is digested more slowly than whey protein, it can be concluded that casein is more difficult to digest. However, the rate of absorption should not be confused with the actual protein absorbed. In fact, casein has high digestibility.
Is Whey or Casein Better for Bulking? Or Weight Loss?
Regardless of your specific dietary goals, both types of these high-quality proteins can be part of your diet. The key role belongs to the total calories and the total amount of protein you consume per day. However, a casein protein supplement may be better at keeping you full longer, which can help curb hunger during weight loss. But this is not a set-in-stone rule, so your preferences should dictate which type of supplement works best for you.
Conclusion
Like any other good protein supplement, best casein protein powder should contain 24-30 g of protein per serving. It is a high-quality and highly digestible protein that contains a large amount of BCAA and leucine. In addition to the amount of protein, pay attention to the amount and type of carbohydrates, fat, calories per serving, as well as the amount of sodium. The advantage of casein over other protein supplements is the highest amount of calcium and great thickening properties. The best in this rating is 100% Grass-Fed Casein by Transparent Labs.
