Casein protein is derived from milk like whey, and is a complete protein known for its slow digestion, taking several hours to absorb fully. This slow digestion rate may help support muscle growth during long periods without food, like overnight, and it may help manage hunger during weight loss. (

) Additionally, many casein-rich foods are high in calcium, supporting bone health. (

)
Most dairy foods will give you a healthy dose of this protein, with dairy milk, for example, providing about 80% casein and 20% whey. Casein protein powders can also be a convenient way to maximize your intake within a specific diet plan. So which one is best to get you to your goals? Our team of dietitians and fitness experts did a deep dive into some of the
best protein powders
. We evaluated ingredient quality, safety, value, taste, customer satisfaction, and more. Using these insights, we compiled the following list of best casein protein powders to help you decide what might work best for you.

Why we like Legion Casein+ as the best overall casein protein powder
Legion Casein+ offers a convenient way to boost your daily protein intake in a nutritionally well-rounded formula. Each scoop provides 24-26 grams of micellar casein protein and 50-60% of your daily calcium needs with no added sugars, two to five grams of carbohydrates, and 110-140 calories, depending on which flavor you choose.
Experts often prefer micellar casein since it maintains the natural structure of casein protein, which coagulates in the stomach and slows digestion. Other forms of casein, like casein hydrolysates, are processed into smaller molecules, losing some slow-digesting benefits. While micellar casein is more popular, there’s no clear proof that one type is better than the other. (
3
,
4
)
“Casein has always been marketed as the slower digesting protein that fitness enthusiasts could benefit from consuming overnight or other times they may have a long time without food. While this benefit was heavily marketed many years ago, it’s interesting to see that research has caught up and there are data suggesting at least 40 grams of casein protein, post exercise and around 30 minutes before sleeping, can help sustain muscle during the overnight fast,” adds Chris Mohr, PhD, RD. (
1
)
Although Legion’s nutrition profile is comparable to that of the other products on our list, it stands out for a few reasons. First, it uses only naturally derived flavors, sweeteners, and food coloring. It’s also soy-free, gluten-free, and non-GMO project verified, meeting many people’s dietary needs.
Legion goes the extra mile to pursue best practices in sourcing. Their casein is sourced from Truly Grass Fed ®, a brand of Irish dairy products committed to sustainability and animal welfare. According to their website, they guarantee that their cows live on pasture and eat grass 95% of the year. None of their products contain hormones or antibiotics.
Finally, for safety and integrity, Legion sends its products for third-party testing to check for ingredient potency and harmful contaminants. They also avoid making sensational claims on their website, providing realistic information about what this product can help with. Best of all, they stand behind their products with a 100%, no-questions-asked money-back guarantee. They don’t even require you to send the product back to them, so there’s very little risk in trying it.
Still, there are downsides. At $2.00 per serving, Legion Casein+ costs more than most of the other brands on our list. The good news is that their subscription program discounts their products to $1.80 per serving, which is more in line with the average cost of casein protein powder.
You should also be aware that Legion products contain stevia as well as sugar alcohol, which can cause digestive symptoms in sensitive people. (
5
)
Nonetheless, our testers enjoyed the flavor and consistency of this product. Four flavors are available—Dutch chocolate, French vanilla, cinnamon cereal, and strawberry—which they described as thick but not too sweet.
It’s worth noting that Legion Casein+ works best when mixed with milk rather than water. When mixed with water, it leaves an unappealing chalky taste that will coat the inside of your mouth. Also, if it sits too long, the mixture will start to separate.
What customers are saying
1,037 reviewers on Amazon have rated Legion Casein+ and overall, customers are happy with the taste and quality of casein powder.
“It’s tasty, has a really nice smooth and creamy texture, mixes well, and has a great protein for calories ratio. On the pricier side, but I find this to be of an excellent quality, and it justifies the price for me.”
Alicia H., Verified Amazon Buyer
Jeff D adds, “What I really like is that the marketing does match what their products are. They don’t have as many random ingredients with questionable data behind them and are more simple. Some people look at that as a negative, but I would rather use quality products that are intentionally designed than the kitchen sink ones.”
Among the few complaints, customers recommend handling the product carefully, as the fine powder can easily make a mess. And, if you don’t like stevia, you won’t like this product.
“This may not apply to anyone else, but I, personally, can’t handle Stevia as a sweetener,” James writes. “To me, it tastes just like aspartame—a very chemical-like aftertaste. I’m sure this is just a matter of taste (or perhaps how I’ve trained my taste buds), but I wasn’t a huge fan of this stuff in the amount necessary to make a shake. Just too much Stevia flavor for me.”

What you should know
Transparent Labs provides 25 grams of 100% grass-fed micellar protein for just 120 calories per serving. With rich
chocolate flavor
and a healthy dose of
calcium
, Transparent Labs is an excellent choice, but you’ll want to be aware it contains a fair amount of sodium at 300 milligrams per serving.
-
Our testers loved the taste and think this product is especially well-suited for making high-protein pudding and ice cream. However it does take some effort to mix fully.
-
At $2.00 per serving, Transparent Labs’ casein is expensive compared to other products on the market.
-
This is great for chocolate lovers who want a versatile product they can look forward to eating.
Pros
25 grams of casein per serving
No artificial ingredients
60% of daily calcium needs
Why we like Transparent Labs 100% Grass Fed Casein as the best-tasting casein protein powder
Transparent Labs is known for creating quality supplements with straightforward formulations, and their casein protein powder is no exception. A one-scoop serving delivers a substantial 25 grams of 100% grass-fed micellar casein and 60% of your daily calcium needs with no added sugars, only four grams of carbohydrates, and 120 calories.
However, it’s worth noting that this product has the highest sodium content on our list, with 300 milligrams per scoop, slightly over 10% of your daily limit.
This casein’s simple ingredient list is free of soy, gluten, artificial sweeteners, and dyes. Plus, sourcing from grass-fed cows may help boost this product’s nutrient content while limiting exposure to hormones and antibiotics, according to some data. (
6
) Note that it does use stevia, which some customers may wish to avoid. Additionally, this supplement is Informed Choice Certified, meaning a third party tests it for harmful and banned substances.
Beyond these benefits, Transparent Lab’s casein gets extra recognition for its great taste. The only available flavor is chocolate, but our testers raved about it. They love its rich chocolate taste with a subtle hint of saltiness from the Himalayan rock salt. A popular recommendation is to use this powder to make chocolate pudding. To do so, simply add less water than instructed. One tester compared it to a classic Jell-O pudding cup, highlighting its smooth texture and authentic chocolate flavor.
At $2.00 per serving, Transparent Labs 100% Grass Fed Casein is our list’s second most expensive product. However, if you crave a chocolate treat, it just may be worth it.

What you should know
Nutricost offers 24 grams of micellar casein at about half the cost of comparable products, making it a more affordable option for those needing multiple servings to meet higher protein targets for muscle gains.
-
While this casein has an unmistakeably gritty texture, it mixes well with milk and is versatile enough to use in baked goods. These work arounds easily mask that texture issue.
-
At $0.94 per serving, this is one of the most cost-effective casein options on the market.
-
Nutricost’s casein is best for people who are actively trying to build muscle mass, as it provides an affordable way to boost their protein intake.
Pros
24 grams of micellar casein per serving
45% of daily calcium needs
Convenient five-pound container
Cons
Contains artificial flavors
Why we like Nutricost as the best casein for muscle gains
Nutricost provides 24 grams of micellar protein in each serving for about half the cost of comparable products. This affordability is a plus for people wanting
protein powder to build muscle mass
who may need more than one serving daily to meet their protein goals.
Research suggests that to gain muscle strength, you need about double the recommended daily allowance (RDA) for protein intake, approximately 1.6 grams per kilogram of body weight. (
7
,
8
) To maintain these gains, casein is often recommended as a bedtime supplement because its slow digestion can prevent muscle breakdown overnight. However, these benefits are only seen with doses of at least 40 grams taken post-exercise and about 30 minutes before sleep. (
1
) Nutricost can help you hit these high-protein targets without breaking the bank.
Nutricost’s vanilla casein is also versatile. It works well in chocolate peanut butter protein waffles and high-protein cookie dough, meaning you don’t have to drink multiple
protein shakes
to hit your protein targets. (You can find these recipes and more on Nutricost’s website.) Plus, its lean nutrition profile allows you to create recipes dialed in to your specific nutrient parameters. One serving contains just 110 calories, one gram of carbohydrates, and 190 milligrams of sodium.
Another perk Nutricost brings to the table is convenience. The Nutricost casein comes in a five-pound tub—71 servings. If you’re taking two servings a day, this will last you well over a month.
It’s worth noting that this product does contains artificial flavors and sucralose, which some people may wish to avoid. On the bright side, it’s third-party tested, so you can rest easy knowing it’s monitored for harmful substances like heavy metals and contaminants.
What customers are saying
Nutricost Vanilla Casein has garnered over 1,800 customer reviews on Amazon. Most appreciate its versatility and affordability and think the flavor is decent.
“This is really good stuff. High quality, low calorie, pretty good flavor. It mixes well with almond milk and frozen fruit for a smoothie to curb cravings.”
Andrew, Verified Amazon Buyer
Another customer, Tom F., describes it as a “good product” at a “great value.”
However, other reviewers think it’s just okay due to the gritty texture. Nathan S. writes, “It’s not the best tasting, but it’s great for long-digesting protein.”

What you should know
Jacked Factory provides 25 grams of grass-fed micellar casein protein at a comparatively affordable price point. Plus, this product has a delicious

you’ll look forward to adding to your meals and snacks. The lack of
third-party testing
is a major downside but helps keep product costs low.
-
This product rates highly for its taste and blend-ability, particularly compared to other products on the market.
-
At $1.33 per serving, it’s the second cheapest option on our list while maintaining quality.
-
This is best for people who want to reap the benefits of casein protein on a budget.
Pros
25 grams of micellar casein per serving
60% of daily calcium needs
No artificial dyes or fillers
Why we like Jacked Factory as the best budget casein
Jacked Factory earned our best budget spot since it offers excellent value for the price point. Each serving provides 25 grams of grass-fed micellar casein protein, and a month’s supply costs just under $40; other options generally range between $40 and $60.
Each serving of Jacked Factory casein provides 60% of your daily calcium needs and five grams of
branched-chain amino acids
(BCAAs), essential nutrients for supporting muscle growth and recovery. (
9
) This is typical of most casein protein products. A low-calorie content of just 110 per serving, plus no added sugars and only three grams of carbohydrates, helps this fit into most diet plans. Jacked Factory casein is also sourced from grass-fed cows and is non-GMO, gluten-free, and soy-free.
This product’s delicious vanilla flavor and ability to blend well add to its value. However, you may not like that this product contains sucralose, a no-calorie sweetener.
The most significant downside to this product is the apparent lack of third-party testing for product potency and safety. However, this omission helps keep costs low.
What customers are saying
Amazon reviewers are generally happy with this product. What they like best is the taste, ease of use, and value, especially compared to other products they’ve tried.
“The best casein I have had thus far. Upon trying this casein, I found myself really liking it. I mixed it with water first, and it blended really well, next time I tried it was with almond milk and mixed just as well. The taste is really good actually, and I have no complaints there.”
Adam R., Verified Amazon Buyer
Customer Alex agrees, writing, “I have tried 3 different brands of casein, and this is by far my favorite. The thickness, taste, everything is A 1. I love the fact that it’s clean with no fillers. You can almost mix it with any isolate, and the vanilla does not overpower, in my opinion. I will be buying again and will recommend to others.”
On the other hand, some customers wish it had a cleaner label.
A reviewer with the initial A writes, “Tastes great, almost a little too sweet. It tastes like vanilla pudding. I wish they had a little bit cleaner ingredients like the sweetener, but overall, I’m satisfied with this purchase.”

Pros
25 grams of micellar casein per serving
Convenient, five-pound package
Lower-calorie and sugar-free
Cons
Does not mix well in plain milk or water, even in a shaker bottle
Why we like Promix as the best unflavored casein
Promix is a great unflavored casein option because of its minimal ingredients, versatility, and affordability. Each two-scoop serving provides 25 grams of grass-fed micellar casein with no artificial sweeteners or additives, making it a good fit for people seeking a simple and versatile protein supplement.
With Promix’s unflavored protein powder, you can create recipes with flavors you enjoy instead of being stuck with chalky, artificially sweetened protein powder. Our favorite ways to use unflavored casein powder include adding it to pancake batter, mixing it into oatmeal with cinnamon, or blending it with vanilla almond milk, bananas, and ice. Promix’s formula reportedly works well with these types of recipes, adding a creamy texture without a chemical aftertaste.
However, we learned that Promix doesn’t dissolve well in plain milk or water. Instead, it leaves a gritty texture and an unpleasant aftertaste. The same issue occurs when it’s mixed with plain liquid in a shaker bottle.
Still, a major advantage of Promix’s unflavored casein is its straightforward formula, containing only two ingredients: casein and sunflower lecithin. This simplicity results in an impressive nutritional profile with just 105 calories, 45 milligrams of sodium (the lowest on our list), no sugar, and 63% of your daily calcium per serving.
Promix’s pared-down formula also keeps it affordable; at $1.14 per serving, it’s one of the best values available. Additionally, it comes in a five-pound package that lasts over two months, offering extra convenience and cost savings.
Despite its reasonable price, the company commits to ensuring ingredient quality. This casein is ultra-filtered to remove lactose for easy digestion, and each batch undergoes third-party testing.
What customers are saying
Promix casein has received 600 customer reviews on Amazon. Customers praise this product for its quality and simplicity.
“It’s what the casein does NOT have that should get your attention!” After searching for a quality protein powder without additives or sweeteners for a while, she feels “Promix nails it! In fact, I am so impressed that I recommended it to health food stores in my area.”
VibrandRebel, Verified Amazon Buyer
Ddfusc, another verified customer, feels similarly, writing, “I wanted a casein protein without any artificial sweeteners (aspartame, sucralose…). I didn’t know if I would like something that has no flavor but when I mixed this (very easy to mix, no clumps) with almond milk it just tastes like regular milk which is great. In smoothies I’ll use different frozen berries and it is awesome. Also doesn’t have any weird chemical aftertaste like you get with other proteins.”
Most negative reviews complain of a gritty texture, undissolved clumps, and chalky aftertaste when shaken or stirred into plain liquid.

What you should know
Naked Nutrition Vanilla Casein contains 26 grams of micellar casein protein, sourced from hormone-free cows on farms in the United States. It contains only three ingredients—casein, natural
vanilla flavor
, and coconut sugar—offering a
clean-label flavored option.
-
This product works best when blended into
smoothies
. It doesn’t dissolve well in plain milk or water since lecithin is excluded from the ingredients.
-
At $1.64 per serving, Naked’s casein is just below the average cost for similar products.
-
It’s best for people who like flavored protein powders but want to avoid unnecessary ingredients.
Pros
26 grams of micellar casein per serving
No artificial ingredients
Cons
Requires blending to dissolve fully
Contains five grams of added sugar
Why we like Naked Nutrition Vanilla Casein as the best natural casein
Naked Nutrition provides 26 grams of micellar casein in a vanilla-flavored mix with just three ingredients: casein, natural vanilla flavor, and coconut sugar. While other options include calorie-free sweeteners like sucralose and stevia, this product helps you avoid that chemically sweet aftertaste.
The trade-off is a higher added sugar and calorie content. One serving provides five grams of added sugar and 130 calories. While not deal-breakers, you’ll want to keep this in mind, especially if you need multiple daily servings to hit your protein targets.
Naked casein is also one of the few that doesn’t contain lecithin. This ingredient is typically added to powdered supplements to help them dissolve better in liquids. In keeping with their commitment to use minimal ingredients, Naked Nutrition has not included it.
Our testers found it harder to get this product to dissolve in a shaker bottle, but it eventually did when mixed with the maximum recommended amount of water. Ultimately, this is another one that you may be better off including in blended smoothies rather than stirring into plain water or milk.
Aiming to reduce the steps between farms and food, Naked Nutrition sources its casein exclusively from hormone-free cows in the United States—though there is no indication that they are pasture-raised or grass-fed.
This casein protein powder is also cold-processed, which means it’s not exposed to bleach or detergents, and it’s third-party tested, though the results aren’t made available to the customer.
The convenient five-pound package should last you at least two months, and it’s relatively affordable, with a price point just below average for a product like this.
What customers are saying
Naked Nutrition Vanilla Casein is a popular product, garnering over 2,000 mostly positive customer reviews on Amazon. Reviewers frequently praise the product’s ingredient quality.
Verified customer Carol Nunn writes, “this product has that hard to describe taste of quality and simplicity. I find it superior. I did not want to finish the other (expensive) Micellar casein product. As a healthcare provider would also recommend this to older adults to prevent muscle wasting. The research supports this benefit.”
And another customer, Meimei, describes this as her “purchase of the year.”
However, there are a fair number of negative comments about flavor and the difficulty of getting this product to dissolve. Even so, most reviewers find it acceptable enough for the benefits.
For example, Caleb Cook shares, “If you’re here for the taste, go somewhere else! Run as fast as you can! Cuz this stuff ain’t even trying to taste good, like not even a little bit. But if you came for a clean and high-quality product without all the extra additives you can’t pronounce, then stick around, cuz this product is for you!”

Why we like Optimum Nutrition Platinum Rebuild as the best casein and whey option
Optimum Nutrition’s Platinum Rebuild provides 24 grams of protein from casein and whey sources, plus other ingredients to help maximize muscle performance and recovery.
When it comes to optimizing muscle gains, getting enough total protein is the most important factor. However, different protein sources play different roles in muscle health, and you may be able to fine-tune your results by leveraging the advantages of each. (
10
)
This product contains whey and casein, the two types of protein found in milk. Both
types of protein powder
are complete proteins, meaning they contain all of the essential amino acids needed to support muscle growth; however, they act differently due to how they are digested.
Whey is considered a “fast protein” because it digests quickly. This makes it best to consume after a workout, as it rapidly replenishes muscle protein stores, aiding muscle growth. Conversely, casein digests slowly, gradually releasing amino acids into circulation. This helps prevent muscle breakdown. By combining these protein sources, Optimum Nutrition gives you the best of both worlds. (
11
)
Two additional ingredients are included in this product to help enhance your results: creatine monohydrate and L-glutamine.
Creatine is an amino acid shown to help improve muscle strength and performance. According to the International Society of Sports Nutrition (ISSN), three to five grams of creatine are needed daily to see benefits. Optimum Nutrition provides three grams in each serving. (
12
)
L-glutamine is another amino acid thought to improve muscle recovery, but so far, research shows minimal effects. (
13
) Nonetheless, each serving of Optimum Nutrition’s formula contains three grams of this amino acid.
These extras make this product more expensive—$3.00 for just one serving. However, this brand is highly regarded among athletes for its Optimum Nutrition Gold Standard whey protein, which many consider the best around.
A full-size tub only provides 20 servings, so be prepared to order frequently. Two flavors are available: dark chocolate and vanilla buttercream.
If sustainability and clean labels are important to you, you may want to look elsewhere. Artificial flavors, gums, sucralose, and acesulfame-K are included in this ingredient list. There’s also no indication this product is sourced from sustainable or grass-fed sources.

What you should know
Dymatize
Elite offers a nutritionally well-rounded protein supplement containing 25 grams of micellar casein per serving. It stands out with its uniquely delicious four flavor options and remains accessible to many due to its affordable price point and convenient packaging.
-
Our testers enjoyed making pudding from the cookies and cream flavor. They felt this product kept them more full and satisfied than other casein products, making this a potentially great option for people trying to manage their weight.
-
At $1.40 per serving, it’s just below the average price of similar protein supplements.
-
This is best for people looking for a dependable protein supplement they won’t dread eating.
Pros
25 grams of micellar casein protein
Helps with hunger control
50 servings per container
Cons
Contains artificial ingredients and sweeteners
Unclear if tested for more than just banned substances
Why we like Dymatize Elite as the best micellar casein
All of the products on our list contain micellar protein because it is the preferred option for maintaining casein’s natural properties. (
11
) However, Dymatize Elite deserves a special call-out on this list because of its long-standing popularity, affordable price point, range of flavors, and third-party validation.
Like the others, this product provides 25 grams of micellar casein in each serving, offering a convenient way to boost protein intake. Each serving also provides 45% of your daily calcium needs and only two grams of fat, three grams of carbohydrates, and 130 calories, giving it a well-rounded nutrition profile.
Living up to its reputation for great taste, our testers thoroughly enjoyed the four flavors available: chocolate, cinnamon bun, cookies and cream, and vanilla. The cookies and cream flavor seemed to be the best option for making a satisfying high-protein pudding.
Interestingly, one of our testers noted that Dymatize kept her really full, more so than any other product she’s tried, though she couldn’t pinpoint why.
This isn’t the cheapest product, but at $1.40 per serving, the price is below average. And with 50 servings per container, it should easily last a month or more. We also liked that this product is Informed Choice tested for banned substances, though it’s unclear if any further testing is done for other contaminants.
Another factor some people might not like is that this product has soy-based additives and artificial ingredients. These include soy lecithin, tricalcium phosphate, sucralose, acesulfame-k, potassium chloride, and multiple gums and fillers.
What customers are saying
Dymatize is a well-rated and popular casein protein powder on Amazon, where nearly 8,000 reviews. Customers are generally happy with the taste, texture, and the way this product keeps them full for hours.
“Believe me when I say this is the best-tasting protein I’ve had the pleasure of purchasing. Honestly, it tastes like a Chick-fil-A shake, if Chick-fil-A had a cinnamon flavor. And I’ve only been using one scoop per 8oz water. I can only imagine how 1.5 scoops tastes with milk or vanilla almond milk.”
Gabe, Verified Amazon Buyer
Manish Kumar agrees, sharing, “I’ve been using this protein powder for about a couple of weeks now, and I’m really loving it. It’s so easy to dissolve, and it has a great chocolate taste. I love that it keeps me full until morning, and it comes with the BCAAs and amino acids that I need to build muscle. I’ve read other reviews that say the taste can be a bit too sweet, but I personally don’t find that to be the case. I think it’s the perfect balance. Overall, I would definitely recommend this protein powder to anyone looking for a convenient and effective way to boost their protein intake.”
However, some customers do have complaints about the taste, and texture. Also, a few note they have difficulty getting into the packaging.
W.R. Lucas gripes, “Why is the cap so hard to remove??? I love the product. Great taste and great results. For the last several months, I have had to use tools to get the cap off. Today, it took a hammer. I have been using this product for a decade. It was not like this in the past.”

Benefits of casein protein powder
Getting enough protein is important for overall health. According to the Recommended Daily Allowance (RDA), most people need a minimum of 0.8 grams of protein per kilogram of body weight daily, which equates to about 65 grams of protein daily for a 180-pound person. (
7
)
However, recent research indicates that more protein may be needed to truly optimize health. A 2019 review suggests that 1.2 to 2.0 grams of protein per kilogram of body weight daily support athletic performance, weight management, and muscle maintenance during aging. This equals 98 to 163 grams per day for the same 180-pound person. (
8
)
Protein powders
offer a convenient way to increase your protein intake, and casein protein powders offer specific advantages. The following are a few that stand out:
Helps with muscle growth and recovery
To build and maintain muscle, your body needs to grow more muscle than it breaks down. Tough workouts, weight loss, aging, or illness can cause muscle breakdown. Eating enough protein helps repair and build muscles, keeping this balance in check. (
8
)
Casein is a high-quality
protein powder choice
because it contains all nine essential amino acids, including branched-chain amino acids crucial for muscle building. Unlike whey protein, which acts fast, casein’s slow digestion means it releases amino acids steadily into the bloodstream. (
1
)
This slow digestion ensures your muscles receive protein for up to six hours, helping to prevent muscle breakdown and safeguard muscle mass, especially during periods of fasting such as sleep. (
1
) For this reason, people often take it before bed to aid with overnight muscle recovery.
Research backs this up. A 2021 review showed that taking 20 to 40 grams of casein 30 minutes before bed increased overall protein production in young and elderly men overnight. Similarly, a 2020 review found that consuming at least 40 grams of casein before bed enhances muscle recovery and performance the next day. However, more research is needed to solidify these findings. (
14
,
1
)
Aids with hunger management
Due to its slow digestion, casein might be especially good at managing hunger, but studies are mixed. (
15
)
While it’s unclear if casein is better than other proteins for hunger control, high-quality proteins like casein are known to reduce hunger, the desire to eat, and hunger-stimulating hormones. Therefore, incorporating casein into your diet can contribute to overall satiety and better appetite management. (
16
)
Supports bone health
Protein intakes above the RDA of 0.8 grams per kilogram of body weight per day from any source may help reduce bone density losses and the risk of features, particularly in older adults. (
17
)
Casein protein powders can be rich in calcium, further supporting bone health. (
2
)
Who should use casein protein powder?
Casein protein is a good choice for anyone looking to build muscle mass or increase their overall protein intake; however, it may be ideal for specific groups of people.
Due to its slow and steady release of amino acids, it may be particularly helpful to people who work out in the evening and want to promote muscle recovery overnight or who have multiple training sessions throughout the day and want a steady supply of essential amino acids.
Additionally, casein may be helpful for people who need to manage their hunger during weight loss or between long periods of eating because of scheduling demands or intermittent fasting diets. Its slow digestion may help you feel fuller longer.
What to look for in the best casein protein powder
-
Nutrition profile.
In addition to total grams of protein, check calories, protein, sugar, and fat content to ensure your choice aligns with your overall diet goals.
-
Ingredient quality.
Avoid products that don’t fully disclose the ingredients in their formula. Look for options that avoid unnecessary additives that may cause adverse reactions or interactions.
-
Third-party testing
.
Prioritize options that conduct third-party testing for potency and purity. This is the only way to know for sure that what is on the label is what you’re getting and nothing else.
-
Taste and cost.
Taking a supplement is the only way for it to work. Make sure you pick something you like to eat and that you can afford.
FAQs
What type of casein is best?
Micellar casein is the least processed version of casein and, therefore, more likely to maintain casein’s slow-digesting benefits, though research is ongoing in this area. (
3
,
4
)
How much casein protein powder should I take?
One to two scoops (25 to 40 grams) after a workout or before bed for
muscle recovery
is typical. However, your ideal dose will depend on your health and fitness goals. Make sure you’re getting a variety of different proteins in your diet, and speak with your doctor about how much protein you need.
Who should not take casein protein powder?
Casein protein powders
are not a good choice for anyone with dairy allergies or for people looking for a
vegan protein powder
. Additionally, certain casein supplements may not align with Kosher or Halal diets.
Is casein protein powder or whey protein powder better?
Both casein and whey are quality options for increasing
protein intake
. Each supplies the nine
essential amino acids
your body requires. However, they serve different roles in your fitness regimen.
Whey is fast digesting, spiking amino acid levels quicker and higher than casein. It also contains more
leucine
, which triggers
muscle building
. (
18
) For this reason, it may be best used immediately post-workout to replenish fatigued muscles.
On the other hand, casein digests more slowly, providing a steady protein supply to muscles, which helps protect against breakdown and can aid in managing hunger. Due to its gradual release, it’s best suited for periods of fasting, such as overnight or during calorie-restricted diets. (
11
)
When should I take casein protein powder?
Casein can be taken anytime, but research suggests taking it 30 minutes before bed can provide muscle health benefits overnight.
