Professional Whey Micellar Casein MPI is an awesome slow releasing casein protein powder that is perfect to consume as a source of night time protein, or even during the day for slow absorption. As it is very slow digesting protein it provides a lengthy release (approx 7 hours) of amino acids because of its unique composition.

This makes it ideal when a lengthy supply of protein and amino acids are needed to avoid catabolism (muscle breakdown) and improve recovery such as during sleep.

It is sourced in Australia from the skim milk of pasture fed cows that are free from any herbicide or pesticide residues. The milk is collected daily and within 24 hours it is processed through ultra-filtration to enable the protein to remain highly undenatured.

The finished product is Milk Protein Isolate (MPI), nature’s finest blend of milk proteins: casein and whey protein, 80% and 20% respectively. Making it the perfect combination of predominantly slow and a little fast released protein. The facts are:

  • Ultrafiltration ensures a high level of undenatured protein due to its low temperature processing
  • High Level of Undenatured Protein Fractions
  • From Pasture Fed Cows that graze on the grass and clover pastures
  • Free from Genetically Engineered Recombinant Bovine Growth Hormone (rBGH)
  • Free from acid processing
  • Slow Absorption of amino acids into the bloodstream for up to 6-7 hours
  • High Level BCAA’s (Branch Chain Amino Acids)
  • High Protein at 86g per 100g on a dry matter basis
  • Pure, untouched with no fillers, preservatives or flavourings
  • Low Fat at 1.3g of fat per 100g
  • Low Carb at 4.7g of carbs per 100g
  • Easily mixes in water or milk
  • Non GMO, Kosher, Halal, Vegetarian Approved and Gluten Free

Micellar Casein MPI is one our most popular types of casein for mixing with both food and drink as it works just like a natural thickening agent and helps promote a richer, creamier texture giving that silky smooth taste. We offer both 1kg and 20kg sizes and the more you buy, the more you save, with our bulk buy discounts.

Note: Our Micellar Casein MPI dissolves a lot easier than our Calcium Caseinate and has a more pleasant taste.

Mixes well in glass of water or in cooked oats, bland taste which is what I want, low sugar low fat high protein.

Micellar Casein MPI [Natural 1kg]

By: on 20 September 2023
It's natural so it is rather bland but that is what I wanted, the best feature for me is it is so easy to mix I put it in my oats every morning and I think it improves the taste which is a bonus, it also tends to aerate my oats which is normally quite thick. I'm giving 5 stars on this product.

Tried and trusted over the years..

By: on 28 May 2022
I've been consuming MPI from Professional Whey for over several years and it never disappoints. Consistent quality. Inherently MPI is thicker and takes longer to liquify when blending/mixing in your shake but it certainly helps fulfil my daily protein intake and I do notice MPI keeping my appetite satiated for longer than for example the quicker absorbing WPI. MPIs a staple in my daily protein intake and I recommend it.

Night time protein top up

By: on 11 October 2020
Stacking Ajinomoto Glutamine with WPI, WPC, Casein & collagen hydrolysate to get my protein levels up to 100g/day. I'm feeling energetic, better concentration, sore feet is much reduced & recovering from a hard days work seems much improved. I like this company, good clean products.

Micellar protein

By: on 17 August 2020
Absolutely love how clean this product is, it mixes well, And I enjoy the natural Taste, I have 1 1/2 scoops + blueberries Before bed for a more enjoyable shake which keeps me full till the morning. Will definitely be ordering more and only from this company now on. The website is also very helpful as to what ingredients are used in powders these days, wish i knew this years ago!

Yum

By: on 29 April 2020
I've been told how good casein is, however, this is the only one that's pure without any additives. I added some organic raw cacao (no sweetener) and love it before bed and yes, it does actually help me sleep. I sometimes like it as a custard or more like a drink. It's perfect to add to a smoothie too

A reliable slow burning protein solution

By: on 28 March 2019
Like the USA WPI, i have been ordering Micellar Casein MPI for many years now from Professional Whey. It serves me well throughout the day as part of my meal replacement shakes and in the evening if i'm in need of a protein fix to sustain my satiety during my sleep. This type of protein inherently has a thick, gritty texture compared to Whey Protein Isolate. So be mindful to ensure its thoroughly blended and/or mixed into your shake.

For a good night sleep

By: on 12 January 2019
This protein is a great product for when you need to feel fuller for longer. I tend to take Micellar Casein at night before bed, especially if I am restricting calories, as it is sustaining and I don't wake up hungry in the middle of the night. i also like to keep this protein at work, as sometimes I will have it during the day around 3pm to prevent me from snacking on crappy food in the office.
(5)

Fantastic product

By: on 10 August 2018
As usual a brilliant product supplied by the PW Team. It’s everything it claims to be and nothing hidden or added. Great for just before bed, no waking up starving.

Micellar casein MPI

By: on 7 December 2016
It mixes really great with milk, and stops me from waking up starving in the middle of the night, or even the morning. I especially love that there is nothing else added. You know what your getting and it's 100% pure.

Clean Protein

By: on 29 October 2016
This is a well sourced Casein Protein ,I became interested in Professional Whey Casein due to it being a ultra clean Protein. Most other Brands use chemical processing Professional whey do not .How do I know for sure you may ask every other brand I have tried I have broken out in allergies and had indigestion. I have never had any side effects with Professional Whey Casein what I have noticed is a longer feeling of fullness at night and enhanced recovery next morning. I really do like Professional whey and the standards they uphold no crap artificial sweeteners just good clean protein.

Night time bliss

By: on 5 September 2016
I was recommended this product by my trainer as alternative to other Casein mixes. I was a little nervous about trying something new as I normally am. Plus this Casein was not flavoured, which I thought would have been okay. However when I tried the product the taste was overpowering and I could not drink it properly, I tried adding cocoa, adding less water then more, drinking with milk, but nothing was working, I was about to give up when I decided to add a 3/4 scoop of professional whey Cocoa-mint. BINGO, could now drive the shake, and within no more than 2-3 days could really feel the difference in saitety and muse development. Now I love my Casein shake right before bed, normally around 10pm'ish and when I awake at 4am ish, I am still full from the night before, which would not happen with other brands of casein. Can not recommended this product enough, great results and it really does work. Thanks

good casein

By: on 25 August 2016
nice protein, mixed with milk or water makes a consistent creamy - ice cream like food that is good to take before bed especially when mixed with some chocolate powder or cacao. Is a nice quality casein with a reasonable price, definitely recommended
(4)

Good quality casein

By: on 5 May 2016
I have been using their casein for many years. Pure taste as compared to the rest of the brands. Its basically tasteless and dull like drinking chalk, but that's when you know its a pure product. I also like their super fast next day delivery
(5)

Faultless

By: on 30 March 2016
It's basic Casein powder; thick, slow release, tasteless. It's also extremely cheap (perhaps the cheapest protein per dollar period), well packaged, pure (never once found a notable impurity), Australian and clean. Best protein powder I've ever used and I've tried a lot.
(5)

Excellent for Slow Protein Release

By: on 29 March 2016
I have been using MPI Casein for several months and have found it useful for times when a slow protein release is required. Typically I will have it before bed on a training day. Mixed with some Organic Cocoa it tastes good and is easy to drink. I like that it is GMO free with no additives.
(4)

First natural casein purchase

By: on 9 March 2016
Does it mix poorly? Will the natural version taste funky? Will the effort be worth the results? Happy to say the natural Micellar Casein MPI product has been a pleasure. Mixes into a small portion of water with a spoo and is perfectly palatable. Some supplements are dissuasive to use, this isn't, and I look forward to seeing if casein can make a difference to my exercise and diet plans.
(5)

Casein Mousse

By: on 23 February 2016
To curb a sweet tooth in the evening I mix 1 scoop with 1/2 scoop organic cacao NZ WPI, a table spoon of extra cacao powder and a 1/2 teaspoon stevia, enough water to make a thick paste then whisk it up to mousse consistency, chuck in 1/2 cup blueberries and you have yourself a killer desert that keeps you full all night and the peace of mind you're not going to loose any of those all important gains! Awesome product :)
(5)

Yummy:)

By: on 12 February 2016
Tasty when mixed with WPC and/or WPI, to make pre/post workout shake. Different release rates you see! Also tasty mixed with milk for late evening snack

Intravenous Protein

By: on 30 October 2015
I take this before going to bed about 2 serves and it gets me through the night. Less than 2 serves and I'm hungry again about 4am so that's why I go the 2. Excellent product which will drip feed you through the night or other extended periods without food (but you don't really do that do you).Aerates very easily so makes a mess of the bench top quickly, but that's an easy fix. Only tried the natural flavour, keen to try new flavour next time.

Beefcake! BEEFCAKE!

By: on 2 October 2015
I really struggle to eat enough protein from whole food sources, and like other reviewers I don't want to take protein that's mixed with sweeteners, colours and flavours. I've been using the Micellar Casein MPI to make 'beefcake hot chocolate' before bed - a mix of casein, raw cacao, mesquite, vanilla and coconut milk, warmed up in a nice solid mug. It's super satisfying, and I've never woken up in the wee hours starving like I occasionally did. Good stuff.
(4)

Excellent

By: on 29 September 2015
Awesome product so easy to mix in seconds a little bit frothy but tastes great and easy to get down.
(5)

Very clean tasting

By: on 17 September 2015
Very good, clean tasting protein. Pleasant to drink without flavouring. Mixes very easily.

Clean Protein

By: on 28 August 2015
It's difficult building muscle without ingesting all the non food components (flavours, colours, and fillers) of most protein powders. Professional Whey powders are unique. As they are made with milk from grass fed cows and nothing else I know I am giving my body quality protein and nothing else. Feel better, move better, look better, simple.
(5)

Great Product

By: on 26 July 2015
Keeps you full for a long time, mixes very easily in milk or water. Slightly chalky/gritty mouth feel but pleasant to drink. Works particularly well overnight to keep you from getting hungry.
(5)

Best protein powder ever tried!

By: on 8 April 2015
I love this protein powder as it doesn't have any flavour and not overly sweet like many others I've tried. It blends beautifully in my morning smoothie. I use this as a breakfast and it keeps me full and energised throughout the morning. I'll keep using this as the price is also great!
(5)

Excellent

By: on 25 December 2014
I primarily use Micellar Casein before bed to help keep my body satisfied through the night. This protein is a godsend as ever since I've been taking it I have slept much better - no more waking up hungry! I have mine with full cream milk and a mix of cacao/maca powder.
(5)

Can't recommend enough

By: on 12 August 2014
Yes, it tastes like powdered chalk when you mix it with water. But this is very high quality casein at a fraction of the price charged by companies who stuff their product with chemical nasties you're better off without. Do your body and your wallet a favour!
(5)

Pure tasting

By: on 26 July 2014
This product taste dull but that is what I am looking for. It's pure. It may taste like chalk and feels like chalk. But it's definitely the right product for serious athlete who is looking for pure ingredients
(5)

Well priced, great quality

By: on 29 April 2014
Definitely recommend this to anyone who is serious about their health. I have found that this source tastes great, mixes well and has proven positive effects. I have tried many other Caseins, but have found that this is superior in its nature and provides excellent results, without having all the junk that other brands include. 10/10 and i feel i should be paying more for this product it is so good!
(5)

Great addition to night time snack

By: on 28 April 2014
Great addition to my night time snack, either in yoghurt or with mashed pumkin. Mixes really well, makes the food taste thick and smooth and has no strong taste of its own.
(5)

Requesting Flavours!

By: on 11 February 2014
Love this product, but wish we could get some flavours! Cinnamon :):):)
(5)

Great to take before bed!

By: on 3 January 2014
I found this very easy to mix and really aided my recovery. Doesn't make me feel bloated in the morning like some other casein products do. Taste is a bit average, but chuck some cinnamon or cocoa powder in there and you have a great before bed treat!
(5)

Top Notch

By: on 11 November 2013
The best in quality I've had, super ease in mixing with a shaker add a little bit of the organic cacao powder and it's the great before bed snack!
(5)

Perfect for IF

By: on 11 November 2013
Love this product for night time protein intake, can make the yummiest 'ice cream' and great for intermittent fasting as it keeps you satisfied overnight and thru the morning. Will be keeping this as a staple in my pantry. Mixes easily most of the time, I don't often use it in a shaker so not sure about that., thickens like pudding, neutral taste.
(4)

Good results

By: on 4 October 2013
Have been using this for 4 weeks now, great for post-workout recovery
(5)

Versatile protein

By: on 13 September 2013
Very useful as a way to bulk out shakes etc., get some protein without spiking insulin, and also (surprisingly great) in high-protein gluten-free baking. Completely neutral non-bitter taste unlike other caseins.
(5)

First Casein Experience

By: on 13 September 2013
This is the first casein I have tried and I am definitely impressed! I mix it with a bit of water and add it to a mug of cacao dissolved in hot water for a deliciously satisfying hot drink before bed and it really hits the spot. It mixes really well too, definitely will purchase this product again.
(5)

Great product

By: on 7 September 2013
Have this last thing at night and helps me to feel satiated well into the next day. Love the taste, very happy with this product. Mixes well and nice consistency. Great value, like anything from Professional Whey.
(5)

Anabolic V Anti Catabolic

By: on 4 September 2013
I have been training since I was twelve years of age - now at age 53 I would have to say Micellar Casein is the single best supplement I have ever used - and I have used them all. Fast digesting protein after the workout sure but for the rest Micellar Casein
(5)

Mix with water

By: on 24 August 2013
If you are drinking unflavoured before bed, mix it with water and just chug it down. I take this every night before bed, if I don't my stomach is upset and hungry in the morning. If mixing with flavour, is nice with milk. Mixes very well!
(5)

Micellar Casein MPI natural

By: on 12 August 2013
I was recommended this product by my personal trainer. It's done miracles for my energy levels. It also keeps cravings for snacks at bay. Works well with a bit of poached rhubarb and banana (no sugar).
(5)

Easy on the stomach

By: on 5 August 2013
I have trouble digesting some protein powders. No bloating or upset stomach with this one. Very 'talcy' though. It goes into the air and settles on benches etc. This is a minor detail though.
(4)

First time trying casein

By: on 29 July 2013
I love the consistency when i stir some water through it, it's just like a mousse! Can't say the taste is amazing by itself so i add some stevia and cinnamon or whatever floats my boat. I haven't tried any other casein powder before this but from my experience with professional wheys other products i won't even bother, this brand is the best!
(5)

Matt Wood

By: on 13 May 2013
I mix this with the Organic Vanilla Powder 1/2hr before bedtime (+ a glass of water with psyllium husks on the side when needed) instead of eating food porn every night. Fills the gap and tastes nice whilst keeping the protein release flowing.
(5)

Great product

By: on 24 April 2013
Mix with yogurt and berries to form a delicious "thick" desert, helps you wake up less hungry and aids muscle growth and recovery overnight!!
(5)

Good stuff

By: on 23 April 2013
Never used any other casein products before but this one seems to do the job well

Good Stuff

By: on 23 April 2013
Very powdery, I always add a little hot water to my shakes, dissolves much better that way. Quality product and reliable company to deal with.
(5)

Wierd but good

By: on 4 April 2013
Strange, super powdery stuff, don't sneeze on it! but does the job. Blends really well but add some flavouring otherwise it tastes chalky. you'll notice the difference in the morning with this stuff
