NZ Micellar Casein 1kg

Slow Digesting Protein Source.




$45.00 (SGD)

Micellar casein protein is one of the many supplements we offer at NZProtein.

We have recently reformulated our product so now it tastes even better than before!

Micellar is the most popular form of casein and is known as a slow digesting protein.

Casein protein has a number of functions including recovery, muscle growth and improved health. Read below to learn more.

Casein vs Whey Protein

Milk contains two different proteins; whey and casein. The main difference between the two is the rate at which they are absorbed by the body.

Whey is digested relatively quickly whereas casein is a much slower digesting protein.

Both types of protein have their place in a healthy diet however it is ideal to consume them at different times.

Benefits of Casein

Casein is a complete protein meaning it contains all of the essential amino acids your body requires.

The most important amino acid for stimulating new muscle growth is leucine.

Studies recommend 50mg of leucine per kilogram of bodyweight daily if your goal is to build muscle.

Our casein contains approximately 2400mg of leucine per serve meaning it is a suitable supplement for those looking to increase their muscle mass.

Additionally it contains only 114 calories per serve.

This makes it a great option for those who are trying to lose fat and retain muscle.

Casein also contains nutrients like peptides which support the immune system and have a range of positive effects on the human body.

Studies have shown casein can also help to reduce high blood pressure and even lower your triglyceride response after a meal.

For the majority of people, casein is an excellent supplement to improve muscle gains and help you maintain a healthy body fat.


Digestibility refers to the proportion of amino acids available in the bloodstream after consuming food.

Animal proteins, like casein, have a digestibility of around 90% whereas plant proteins are around 45-80%.

This means your body will easily absorb the protein and hardly any will go to waste.

Night Time Protein

As mentioned above, casein is often referred to as the ‘slow digesting protein’.

For this reason it is typically consumed before bed. The rationale is that doing so will reduce muscle breakdown while one is asleep.

When your body has a sustained supply of amino acids, the chances of muscle breakdown significantly diminish.

If you plan on going for a long period without food, a serving of casein protein would be a great option to have before doing beginning your fast.

Made in New Zealand

Like our other whey proteins, casein is made from New Zealand cow’s milk.

New Zealand dairy products are widely regarded as being high quality.

Our cows are pasture raised and grass fed. It is well established that grass fed cattle produce more nutritious milk compared to factory farmed.

Consuming New Zealand made protein not only supports the local economy but is also better for your health.

Taste, Texture & Mixability

We stock gourmet vanilla, chocolate and unflavoured options of micellar casein.

According to our reviews they all mix well in either water or milk, taste great and can also be used in baking.

Blending 32g with water and ice is an easy to make a scrumptious milkshake.

If you get bored of drinking shakes, there are a range of exciting casein recipes to try. The unflavoured option is perfect to add to baking without affecting the flavour profile.

Alternatively you could stir the chocolate flavour into greek yoghurt and make a high protein chocolate pudding. The different uses for casein are endless.

Side Effects

Unless you are vegan, dairy intolerant or need to eat a low protein diet due to kidney/liver conditions, there is no reason you can not consume casein.

Casein protein is safe for human consumption. Some individuals may be sensitive to lactose and experience some bloating however the majority of people will have no issues consuming 1-2 servings daily.

Casein protein is not only nutritious but very convenient.

At only $36-$45 per kilogram, casein prevents deterioration of both muscle and your bank balance.

It is easy to use and makes for a delicious pre-bed snack.

If you currently struggle to meet optimal protein requirements or want to prevent muscle breakdown during a dieting phase then casein would be ideal for you.

all round good for my needs, just a bit more difficult to mix in than i expected. i dont like the texture when i have it alone, so i like to use it mixed with milk as the liquid portion of my banana smoothie

Wow. Delicious. I bought Vanilla flavour. Mixes really easily into Greek yoghurt and some water to loosen it up a bit. Added blue berries and some granola, and topped with caramel no sugar syrup. In the freezer for 15 mins…so good. I have been using another brand (sorry) and the taste was pretty meh, thank god I had this in the cupboard. Highly recommend.

Great product. Mixes easily and tastes delicious. Excellent choice when fasting/dieting/sleeping to give a slow releasing protein source. I have a scoop each of Casein and Whey, with Creatine (of course!), in water each morning. This gets me comfortably through the morning and my lunchtime workout. I have the same at again at night. This has helped me drop fat while also maintaining some strength gains.

I drink double chocolate flavour with soy milk which tasts so good, so I will definetly repeat the order together with vanilla.
Review by: Sari on Mon, Oct 23, 2023 1:12 PM
-Lean, high protein, with a reasonable price.

- I purchased unflavoured to mix in with my smoothie, so I didn't expect an excellent taste itself (Personally 6.5 out of 10)

- Tiny bit of full-filling however my huge stomach doesn't mind lol...

- Quite easy to be mixed with no lump in my bottle

Generally its high quality and worth it. I will definitely repeat purchasing.

I would suggest to purchase flavoured ones for better taste if you wish to drink it by itself.

Great product, very fast delivery
Review by: PATRICK on Sat, Sep 2, 2023 12:13 PM
Great product as usual.
I ordered 5 bags of this in vanilla, and 5 bags of the isolate in banana.
Flavor, consistency, price: all on point as always.

Only complaint is, I wish they would have the nutritional information listed for a 'level scoop' instead of a 'heaped scoop'.
'Heaped' is pretty subjective, and I imagine a lot of people using these products are trying to accurately record their dietary intake as I am.
A heaped scoop also means a mess getting your protein out of the bag, made worse by the hollow part on the bottom of the scoop which gets powder stuck in it easily.

It's a very minor nitpick in an otherwise excellent product.

Review by: Grant on Sat, Aug 26, 2023 11:35 AM
Powder is well priced however it does not taste as good as Musashi High Protein powder and has more static, so harder to transfer to a plastic container. NZPROTEIN REPLY: that's a different product, you can't compare whey to casein.

Thought I'd try this after really enjoying the whey isolate. Really pleased with it - have got each flavour and they are all great. Mixes up and thickens really nicely. Will keep buying this as well.

It is the first time we buy casein and we are really happy with it. Both flavours, vanilla and chocolate, are really good. We mostly use it for our banana breads and muffin. :)

To add to my previous preview. I think it would be great if the flavoured options had better ingredients, especially the sweetner.

It's great, mixes well and fills me up better than whey.
Flavour is good, kind of reminds me of vanilla creamed rice.
Texture is thick and creamy, even when mixed with water.

Mixes smoothly and tastes good! I’m a bit of a sweet tooth so could do with a more sweet creamy vanilla taste, but a bit of sweetner and milk mixed in does it good! Great value for a great price

One of the best caseins I've tried. It solubilizes well and does not foam up as much as some other brands I've tried. I like to let it sit for a while and eat the foam with a spoon before drinking the liquid.

The texture with milk is delicious, with water not so much, but very easy to drink. Not massive scoops for the same amount of nutrients as other brands.

I had picked up from their warehouse, staff were friendly and helpful.

Will be purchasing more shortly and trying the range further

Review by: Christian on Mon, Nov 28, 2022 8:18 PM
Unflavoured Casein. A flavour that works in both savoury, and sweet meals. Cheesy in pasta, creamy in hot chocolate. It generally behaves well in stew, when mixed with oil before any wet ingredients are added.

Interestingly; A bag from the current batch I'd been using (221100-0) for stew and hot chocolates began clumping into soft cheese that had a stretch comparable to mozzarella, although much weaker as it tore quickly. It did this in stew, but not the hot chocolate. This bag was unlike another bag from the same batch. If you happen to find a bag like this, it could be useful for making cheeses, but it sticks to my steel spoon, which I didn't like having to clean.

Excellent product. I use it in smoothies, overnight oats and baking. Lovely smooth texture and delicious vanilla flavour.

Love the micellar casein at night or to help feel full while cutting. Needs to sit for 15 minutes or so post mixing.
Review by: Mark on Thu, Oct 13, 2022 1:11 PM
Would have given 5/5 except the seal on the bag was unsealed when it arrived, this caused a puff of protein to air out and cause slight bit of difficulty closing seal for about a week after. Product looks and tastes great--the flavour is remarkable.

Good flavor
Review by: Anonymous on Wed, Sep 7, 2022 5:20 PM
I would give it 5 stars if it weren’t for the non-nutritive sweetener. I didn’t realise I bought vanilla flavour and was disappointed when I saw it had sucralose in it. Not quite sure what to do with the stuff now. Might just use it as a back up. The delivery was really good and quite happy there are no other filler type ingredients in there. Would be great if they did a vanilla flavour that was not sweet and we could add our own sweetener of choice.
Review by: Anonymous on Sun, Sep 4, 2022 3:33 PM
Use this for overnight oats. Works great and creates an awesome overnight oat meal/snack.
By itself it's standard affair. Tried mixing with regular whey and it ended up being really thick/bubbly. Recommend using it for overnight oats, or shake if you are so inclined.

I'd like to correct my previous 3 star rating because I absolutely love this stuff now. As a shake, it's not the best with the grainy texture but added to Greek yoghurt and porridge it is absolutely amazing. Thickens it up nicely to a creamy dessert. Highly recommended.

Excellent protein for the athletic guy with a high metabolism trying not to lose bulk. I surf for 1-3hr sessions and the muscle recovery with this product is excellent.
Review by: Louigi on Mon, May 2, 2022 1:27 PM
I would give it a 5, but it seems every time I order a new bag they seem to put their protein prices up another 2-5 dollars, I’ve noticed NZ Protein seems to raise their prices far more regularly then other suppliers, I know there is a shortage, but I know bits not that bad, if they keep putting the prices up I may have to go back to my old supplier. 😕

On a good note I quite like the grainy slightly thicker texture of this casein, , the chocolate, is good but not not as sweet as the whey, the vanilla flavour took a while to get used to, but it actually grew on me .😊 NZPROTEIN REPLY: we're really sorry, the price of casein doubled on us overnight. Everything is inflating really fast at the moment :(
Review by: Ryan on Sat, Apr 23, 2022 4:18 PM
Long time consumer of the plain unflavoured NZ protein whey and I love it - add a small amount of cocoa powder and it's very drinkable. This is my first time trying the casein (also unflavoured with cocoa powder added) and it's not very nice. Weird dusty texture and odd taste. Should be OK with half whey half casein + extra cocoa though! Service and delivery amazing as always.
Review by: Paul on Tue, Apr 5, 2022 5:43 PM
Normally get Vanilla which is incredibly good but due to not being in stock opted for Chocolate and found the chocolate flavor not very nice and no matter how much water I put in the shaker I can't get the grainyness away. NZPROTEIN REPLY: sorry, due to shortages we did have to use an alternate casein (mentioned above). 2022 will be a year of shortages.

I blended it up and drank it straight away and was, frankly, concerned because it tasted very powdery. But I left it for sound 20 minutes and by then it had dissolved and tasted delicious and filling, leaving me with a nice, full feeling.

Very good. I've started drinking my protein shakes 2:1 (casein:whey), naturally in milk the protein ratio of casein:whey is 4:1. Drinking whey by itself makes me feel sick from the rapid amino dump, casein slows digestion down and prevents the whey associated nausea. Casein seems difficult to find in NZ. Very happy with this one.

Review by: Anonymous on Mon, May 17, 2021 9:25 AM
Vanilla taste is subtle and not overly sweet. I have it with natural yoghurt, oats, fruit and sometimes cacao powder. It makes it almost a mousse type consistency. The powder is similar texture to custard powder. Keeps me way more satisfied than whey protein I had been using. It’s my new favourite. Will definitely repurchase 😊

Good! I like that it has no flavour so I even use it in baking or my homemade nut bars. As shake, it dissolves nicely and is creamy. I added some milk drops to add the flavour I like.

I use this both as a protein drink and mixed in with oats and it works well for both uses.
Only downside is a very mild flavour but this can be fixed by mixing with other things and not the end of the world.

Great product. Mixes easy and tastes great.

The chocolate flavour tastes great, and goes down well. Will definitely be buying again.

I have been ordering Casein through NZ Protein for a while now, a fantastic product and consistently amazing service by the team. Delivery is normally the following business day and I'm in Christchurch. Although I enjoy this product, I am very excited for the arrival of their cleaner Casein. Can not recommend this product or the team more. 🙂

I love the casein best recommend to everyone. Awesome fast postage. I have also convince my colleagues to order your products thank you
Review by: Kala on Wed, Oct 28, 2020 5:05 AM
This is good. Solves easily in water and has a thick and creamy consistency. I mainly use it in my home made nut bars but tried in a cup of water. Thumbs up from me.

This product is brilliant and great to support NZ made, my third time ordering. Helps keep my protein intake up while pregnant, no artificial additives or fillers. Easy to bake with and add to my children's porridge or smoothies. I also ordered early morning and it was here by 4pm! Keep up the great service NZ Protein.

Good taste, but Double Chocolate is too sweet for my taste.

Love love this product and great being able to purchase a big bag ☺️
Review by: Victoria on Mon, Sep 21, 2020 3:50 PM
When I opened the package I thought it didn't look like 1kg as the bag wasn't that full. I weighed it on some scales multiple times and it was only 700g when it was meant to be 1kg. Flavor is not bad but it does have a bit of a gritty texture especially when mixed in just the shaker. I recommend blending it up with some fruit for a smoothie where it isn't as gritty. NZPROTEIN REPLY: have tried to resolve this but contents of pack have been emptied into refillable tub.
Review by: Ronan on Mon, Sep 21, 2020 10:40 AM
I use this for post workout shakes and baking. It's SOOOOO much better than whey for cooking, as it makes things creamy rather than drying them out. Try 2 scoops in your postworkout pancake batter! It's the best muscle building protein that I know of.
Review by: Brad on Mon, Sep 14, 2020 8:41 AM
Good flavour, reasonable consistency for a protein powder, a little gritty but not awful. Creamy and tasty, easy to drink, and feeling full for many hours later.
Review by: Anonymous on Fri, Sep 11, 2020 12:59 PM
A quality protein at a reasonable price. I find my recovery and body composition have improved while using this product. However, it doesn't mix particularly well (possibly due to the nature of casein)

Review by: Emanuele on Mon, Sep 7, 2020 9:48 AM
Love this protein powder! Easily mixes in with my morning protein shake. I've tried other brands that have ended up being lumpy when liquid is added, but I have no problem with this one. Unflavoured is truly neutral and doesn't leave any weird aftertaste. Protein shake does feel a bit powdery at the end but I think that is due to the fact that I make protein frappes. When I leave it to melt a bit it is good.
Review by: Payal on Thu, Sep 3, 2020 10:07 AM
Really pleased with it to help increase protein while pregnant.
Review by: Anonymous on Tue, Sep 1, 2020 7:18 AM
Good, clean, high-quality protein, as always, from NZ protein. Has a sound flavour profile, and minimal additional ingredients. Mixes well for casein, and is less-chalky than many.
Review by: Augustus on Wed, Aug 26, 2020 8:20 AM
Tastes great and mixes well. Great product.
Review by: Emanuel on Thu, Aug 20, 2020 12:46 PM
Love the natural casein. Easy to ensure I get my daily amount of protein in. Great to add to a glass of milk or some icecream for a good night's sleep.

Great versatile protein powder to increase protein in baking but still keep food moist. Flavour is subtle and blends into ingredients. Recommend, especially if you want to manage a healthy appetite with a slow release fuel...always speedy delivery and great service.

I LOVE this protein. Mixes so well and just fantastic to turn into a delicious custard dessert. Keeps me full and satisfied

Im a huge fan of your products, NZ based, good tasting and a very good price. Any chance of a Salted Caramel in the Casein range?

Great tasting. Good clean NZ protein. As natural as you’ll ever get!! Mixes well, doesn’t cause bloating. I buy all my products from NZ PROTEIN. So reasonably priced too!!
Review by: Sandy on Mon, Apr 20, 2020 10:47 AM
Not the worst casein but definitely pretty chalky texture and not enough chocolate flavour NZPROTEIN REPLY: this texture is the nature of casein. Flavour is always impacted by the texture of the base.
Review by: Sophie on Tue, Apr 14, 2020 12:58 PM
I was bummed when my last supplier of Casein stopped carrying it...but am bummed no longer, since I've found this great product. It's awesome to have unsweetened casein because it cooks brilliantly and can be mixed into virtually anything to increase protein content.

Besides the fine product, customer service is excellent. This was my first purchase here, but won't be my last. Thank you for providing access to such a nice line of products.
Review by: Anonymous on Mon, Feb 24, 2020 3:11 PM
Tastes alright and mixes well in a blender. Only downside is it has a very powdery consistency and coats my throat when I drink it which isn't pleasant.

Really great stuff, love that there's a flavourless version so I can put it in any smoothie combo I like. Great creamy consistency and I feel warm and satiated for hours after. Great metabolic booster, would definitely recommend.

Got Double Chocolate: Awesome Value, I don't like the taste but is drinkable and I will buy more when i need it, Would like more flavours to choose from. I think double chocolate should be renamed to just chocolate and a more chocolate flavour be double
Review by: Don on Mon, Nov 18, 2019 6:10 PM
Casein would have to be my favorite Protein Powder. The 2 favors i choose are very tasty and seem to work well for me. My question is will Casein be coming out in others Flavors?

Good product, I blend it with just a small amount of milk and then leave it to set in the fridge so it?s like a mousse when I have it. Double chocolate is yummy

Definitely noticed a difference taking this before bed every night. Really good taste and mixed in water smoothly.
Review by: William on Thu, Aug 22, 2019 9:52 AM
Much better since the sugar content was reduced. It doesn't get any better than this.
Review by: DG on Sun, May 26, 2019 11:30 AM
The new improved formula has 2/3rds less sugar content to the previous formula. I buy the natural/unflavoured and mix it with a flavoured whey protein, which results in reducing the overall sweetness of the drink.
Review by: Anonymous on Sun, Apr 7, 2019 1:06 PM
Super fast delivery. Great quality and great tasting. Just don't expect it to be like whey in a shake! Casein is slow digesting, and behaves quite differently in water. Fun to cook and experiment with.
Review by: Anonymous on Thu, Oct 4, 2018 10:16 PM
Fantastic product. Great flavors. Mixes better than any other casein I've found. Delivery and service was top notch as always.
Review by: Anonymous on Wed, May 9, 2018 12:15 AM
This stuff is amazing. It tastes great and it's versatile. It mixes well with other protein shake ingredients and can be easily turned in to a great low carb desert by just mixing it with a small amount of unsweetened almond milk and clotted cream.
