Micellar Casein MPI

5 out of 5 stars, 52 reviews

Our 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. It has been sourced in Australia from the milk of cows that graze on pastures.

Our Micellar Casein MPI is a very slow digesting protein which provides a lengthy release 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
  • Non GMO
  • Pure, untouched with no fillers, preservatives or flavourings
  • Low Fat at 2.0g of fat per 100g
  • Low Carb at 5.0g of carbs per 100g
  • Kosher, Halal, Vegetarian Approved and Gluten Free

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

  • Micellar Casein MPI Inhibits muscle tissue breakdown much greater than whey protein (Boirie et al, 1997)
  • Blood plasma amino acid concentrations remain significantly higher than compared to whey protein (Boirie et al, 1997)
  • Increases nitrogen and anabolism (Boirie et al, 1997)
  • Perfect to be consumed before bedtime or at night time

    Micellar casein MPI

    Posted by on 07 Dec 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

    Posted by on 29 Oct 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

    Posted by on 05 Sep 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.

    good casein

    Posted by on 25 Aug 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

    Good quality casein

    Posted by on 05 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

    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.

    Excellent for Slow Protein Release

    Posted by on 29 Mar 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.

    First natural casein purchase

    Posted by on 08 Mar 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.

    Casein Mousse

    Posted by on 23 Feb 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 :)

    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

    Posted by on 30 Oct 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!

    Posted by on 02 Oct 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.
