Slow Digesting Protein

Casein is a form of milk protein that breaks down slowly and provides a release of aminos for up to seven hours, allowing the body to repair and build muscle tissue after exercise for prolonged periods of time.

Micellar Casein is derived from skim milk using low heat and ultra filtration, which prevents it against denaturing.

It is effective before prolonged periods without feeding, such as before bed, to provide a slow and steady release of protein that feeds the body. Casein may also be taken during the day to maintain amino acids in the blood stream.

5 Benefits of Casein:

1. Longer lasting - drinking casein right before bed may be more helpful throughout the night than any other protein option. Source
2. Greater gains - consuming a combination of proteins that includes casein may yield better results. Source
3. Fat loss - may create a higher metabolic rate while sleeping and a better overall fat balance. Source
4. Greater strength - researchers found that it actually doubled the effect that whey protein had on legs, chest, and shoulder strength results, believed to be a result of casein's anti-catabolic properties. Source
5. Dental protection - research found that casein proteins have the potential to reduce or prevent the effects of enamel erosion. Source

Taste and Mixing

This product mixes thicker than whey, therefore we recommend adding more liquid to a serving depending on your desired taste and thickness.

It mixes easily in a blender or hand shaker but like with most powders it's recommended to add the liquid before the powder in your hand shaker. If you're on the go our Fill n Go Funnels take the hassle out of this and make it easy.

Suggested Use

Consuming high quality protein at regular intervals throughout the day can encourage a positive nitrogen balance, aid recovery, and help to increase metabolism.

Depending on your nutritional requirements take 1-3 servings daily. This product digests slowly and is suitable to be taken before prolonged periods without feeding, such as before bed. It can also be used during the day to maintain amino acids in the bloodstream.

Taste is alot better then what I thought! Vanilla tastes good in both milk and water and chocolate just tastes good in milk

Have been using the Casein protein for a long time. Is the most palatable Casein around. Service is always efficient with NZ Protein and ordering is really easily. Highly recommend!
Review by: Anonymous on Fri, Feb 12, 2021 8:32 PM
Nice thick heavy protein to keep you full longer, I'm not a fan of the texture, but the vanilla taste great, and i prefer my protein from grass fed which is why I shop at NZ protein! :)
Review by: Joseph on Fri, Feb 5, 2021 9:12 AM
Perfect for bedtime, mixes well, I like to add this to Anchor Protein Plus Milk and some ice.

Flavour and texture is as expected for this type of Protein.
Review by: Richard on Wed, Feb 3, 2021 9:26 PM
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.
Review by: Anonymous on Sat, Jan 30, 2021 10:12 AM
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.
Review by: Terri on Tue, Jan 5, 2021 12:28 PM
Great product. Mixes easy and tastes great.
Review by: Dean on Sun, Dec 20, 2020 11:49 PM
Taste is a bit light but mixes easy and has good value!

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

Super speedy delivery. Works great for keeping appetite at bay. Happy to be able to contribute to tree planting while taking this supplement.

Review by: Matt on Thu, Nov 5, 2020 12:09 PM
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. 🙂
Review by: Victoria on Thu, Oct 29, 2020 7:11 AM
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.
Review by: Anonymous on Sun, Oct 25, 2020 11:43 AM
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.

Best value for money protein and good tasting product. Ridiculously fast shipping.
Review by: Martin on Mon, Oct 19, 2020 6:10 AM
Good taste, but Double Chocolate is too sweet for my taste.

Review by: Nicky on Mon, Sep 21, 2020 8:58 PM
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: Anonymous on Tue, Sep 8, 2020 8:31 AM
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.

Second time purchasing this protien powder, this time I went for the Double Chocolate flavour and it's delicious. Super fast delivery also. Converted to a returning customer!

Mixes fine, really subtle flavour was hoping for a bit stronger but its fine :)

Mixes well, tastes great and the service from the team was tops, one of my bags was burst and they replaced it with no hassle at all. Thanks
Review by: Anonymous on Thu, Jun 18, 2020 3:40 PM
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.
Review by: Anonymous on Tue, Jun 16, 2020 9:07 AM
I LOVE this protein. Mixes so well and just fantastic to turn into a delicious custard dessert. Keeps me full and satisfied
Review by: Aimee on Mon, Jun 15, 2020 7:14 PM
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?
Review by: Nathan on Wed, Jun 3, 2020 5:59 AM

Great product, tastes good. Works awesome as night time protein specially on days i train super early, i don't feel starving on wake up and have energy to train.
Review by: Kasjan on Sun, May 3, 2020 12:19 PM
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?
Review by: Nathan on Mon, Oct 28, 2019 7:39 AM
Better use blender and i like to mix a tsp of dark cacao
Review by: Jacky on Tue, Oct 15, 2019 2:56 PM
Tasty :-)
Review by: Anonymous on Thu, Oct 10, 2019 8:24 AM
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
Review by: Beverley on Thu, Sep 5, 2019 7:21 PM
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.
Review by: Ben on Fri, Feb 16, 2018 2:11 PM
Great product love the flavour super fast delivery and great service highly recommend
Review by: David on Sat, Sep 23, 2017 3:33 PM
Have loved everything I've bought from NZPROTEIN. The casein included! I'd also rather support a local company instead of all the other plastic crap imported into our country! Highly recommend!

In terms of taste. Best tasting casein protein.mixes and tastes great.
