    BULK POWDERS™ Micellar Casein is a premium source of Micellar Casein, with a fantastic 90% protein content. The milk is ultra-filtered skimmed milk which has high protein and low lactose. Micellar Casein has an impressive amino acid profile, being particularly high in BCAAs.

    Unlike whey, Micellar Casein is a slow-releasing protein. Being pH sensitive, casein coagulates in the acidic environment of the stomach, therefore taking longer to break down and release into the bloodstream. It is the best type of protein to consume pre bed, as during sleep your body will be in starvation mode and start to breakdown muscle. Micellar Casein is also popular during the day, when regular feeding is not possible.

    Micellar Casein boasts an 90% protein, making it a high protein source. Low carbohydrates and lactose add to the excellent nutritional profile, whilst being rich in calcium. We have chosen a premium Micellar Casein to ensure you get a clean flavour profile as well as a great texture. In addition, Micellar Casein is also a good source of phosphorus, potassium and magnesium.


    • 90% protein content
    • Can be used as part of a healthy balanced diet
    • Slow digesting protein source
    • Premium form of casein
    • Ideal pre-bed
    • Contributes to an increase in muscle mass
    • Available in delicious flavours
    • Excellent mixability


    Micellar Casein is suitable for anyone looking to increase their dietary protein intake. Micellar Casein is perfectly suited for those looking for a slow digesting pre-bed shake.


    Can I add this powder to protein shakes?

    Yes, Micellar Casein mixes well with other protein supplements such as whey protein and pea protein. Due to the fact it is derived from the curds of the milk, the appearance is a lot thicker than many other types of protein and therefore, you will need to carefully measure the amount of water and powder to ensure you get a smooth consistency. Blending Micellar Casein with Whey Protein will provide both slow and fast digesting proteins.

    Can I take Micellar Casein if I am lactose intolerant?

    Micellar Casein is derived from cow’s milk and therefore contains a small amount of naturally occurring lactose (approximately 0.4g per serving). If you are extremely intolerant to lactose, we would recommend consuming an alternative source of protein. 

    How does micellar casein contribute to muscle mass?

    Micellar Casein is 100% Casein which is a main constituent of milk, making up almost 80% of the total protein content in cow’s milk. Like whey protein, it is high in protein and contains a range of essential amino acids – although the amino acid profiles varies considerably. This isn’t the only difference either - where whey protein is fast digesting in the gut, casein is a lot more viscous in profile and for this reason, has a lot slower release into the muscle. This making it perfect for a pre-bed supplement. Micellar Casein is produced using a low temperature, microfiltration process to ensure it is high in protein (90%). This high protein content will contribute to a growth and maintenance of muscle mass and is perfect for supporting recovery.

    Hassle free means of adding more protein to diet! Review by Skinny Seaghan
    I add a scoop of the vanilla to my porridge every morning, it's super tasty, mixes pretty well, and doesn't ruin the texture. I also add peanut butter and just water then (no cooking), perfect breakfast!

    Tried the strawberry before and as a shake it tastes a little powdery, but like the vanilla great for cooking/mixing! Try making cheesecake with it, really good! (Posted on 11/12/2017)
    Best casein i've ever tried Review by Lou
    I've tried others but the texture and the quality were not so good. Usually casein does not taste good but I've tasted the choc and strawberry flavours from bulk powders and they taste just like milkshake! Mixes easily as well. (Posted on 08/12/2017)
    Great taste and mixes well! Review by Brock
    This is a really good casein product, tastes great (especially chocolate), mixes really well. Make sure you use more water or milk compared to whey as it mixes a lot thicker (as described in the info). Great to mix with whey to get faster and slower digested proteins together. (Posted on 05/12/2017)
    Great product Review by Daz
    Mixes well with my cottage or quark cheese in the evening. (Posted on 05/12/2017)
    GREAT MACROS, SUPERB FLAVOUR!! Review by Power Pixie
    I recently bought 500g of vanilla (1kg unavailable) & 500g of strawberry. I haven't yet tried the vanilla as it's a fairly staple flavour but have tried the strawberry and have to say it's really rather nice. Flavour is quite mild but definitely strawberry. I recommend mixing with greek yogurt for a "mousse like" dessert & top with granola/nuts/blueberries. Very filling & delicious. (Posted on 03/12/2017)
    MICELLAR CASEIN Review by Glenbo
    Best Micellar Casein I've ever had, also settles in my stomach after a day's eating perfectly, no adverse effects. TOP QUALITY PRODUCT. HIGHLY RECOMMENDED (Posted on 03/12/2017)
    Night time fuel Review by Dal
    Great to be taken as a last meal before bed. Feeding your muscles through the night. Mixes well and tastes great. (Posted on 01/12/2017)
    CHOCOLATE FLAVOUR!! Review by Sr
    The product is thick but is so easy to down because the chocolate flavour is so tasty. It helps when i am unable to intake protein later on in the day. For anyone looking to buy this you should try the chocolate flavour because it is so good. I will always love Bulkpowders for their amazing quality and prices. (Posted on 01/12/2017)
    Very good Review by Darren
    If you are serious about gaining muscle then this product is a must. I've been taking this supplement for many years now and I haven't once been tempted to change it. (Posted on 01/12/2017)
    Best I've ever had Review by Charles
    Best casein I've had easily, tastes really nice, always taken right before bed! (Posted on 01/12/2017)
    AMAZING TASTE, AMAZING QUALITY Review by roorootini
    I am a female bodybuilder who has struggled for two years to find a casein that was at the very least drinkable.
    Having used Bulk Powders intra workout for a couple months now, I decided to purchase it!
    I'm only on my second shake and I'm in love. It tastes great (strawberry), has a smooth consistency and is excellent value in comparison to other brands which, in my opinion, are well overpriced for protein of a lesser quality.
    Bulk powders is the only way forward for me now! (Posted on 17/06/2017)
    DELICIOUS Review by JLangton
    I make a protein mousse with powdered peanut butter, almond milk and cinnamon - its a low calorie dessert which battles the sweet cravings in the evening. Also good to know the casein will be doing it's work while I sleep. I'm onto my 3rd bag of this - amazing! I also mix with vanilla whey when i make a shake and its yummy!! (Posted on 27/02/2017)
    Very High Protein Content Review by MOC
    Bulk Powders Casein has more protein in it than the MyProtein equivalent and is cheaper too.

    The unflavored casein tastes fine. When mixed with other flavored whey it does make everything taste a bit bland but who drinks this for the taste? Mixes well, great price, I will be buying again! (Posted on 06/01/2017)
    Great taste and mixing isn't too bad. Review by James
    The chocolate taste great and mixes pretty well with almond milk. Just wish they did a 5kg bag like their other proteins! (Posted on 16/09/2016)
    Great Review by Josh
    This cassein powder is great in taste - brought the strawberry flavour and there is no bad aftertaste unlike some other products out there. For the price, this is a great product. (Posted on 17/08/2016)
    Finally! A Casein that I can actually enjoy. Review by JM
    I don't know if it's just me, but Casein protein powders seem to be the worst tasting and worst texture protein powders out there!

    I've tried some of the well-known brands' casein, and they tasted sickly. Not only that, but the texture makes you gag whilst drinking it.

    Anyway, that's a thing of the past since trying this one. Although it does have a very slight chalky texture, which could be due to being chocolate flavor, this tastes amazing!
    I can drink this in one go without wanting to throw up like I did with the others.

    If you've experienced anything like I have in the past or just want to try good tasting casein powder, look no further! (Posted on 22/05/2016)
    Good but... Review by Bw
    Good product tasty and all but trying to find the scoop was honestly like trying to find bin laden!! (Posted on 12/04/2016)
    Great taste, mixes well if you read instructions!!! Review by Leighona
    I have just started using this before bed and at first opening it i was a bit sceptical but once mixed with exactly 200ml of water with the strawberry flavour i got a nice thick consistency (i like my shakes thick) it tastes nice enough and mixed extremely well. Since bulk powders have came out i have never changed my protein powder or supps since there whey powder banana flavour is also amazing and actually tastes like a milkshake. Extremely happy with there products!!! (Posted on 03/04/2016)
    Scrumdiddlyumptious Review by hey_funboy
    This is genuinely the best tasting protein I've ever bought, and I've bought a lot over the years. I got the strawberry flavour, which is nice.

    I found the best thing to do is mix it with natural yogurt and pop it in the fridge for a half an hour or so before eating. It sets into a kind of mouse and is surprisingly tasty ! Yum. (Posted on 11/03/2016)
    good taste Review by Gus
    Bought in chocolate and it's better tasting than other online suppliers. (Posted on 29/12/2015)
    Unflavoured tastes quite good actually! Review by Rav
    Unflavoured tastes of nearly nothing but with a slightly creamy milky taste, but I add a spoon of hot chocolate to it and half hemp or almond milk and water. I have a SmartShaker slim and it mixes perfectly in it with zero lumps so am not sure what shaker Jay above is using, but perhaps he should try a different one.

    It does froth up something chronic so perhaps I will try to stir it next time to see if it makes a difference.

    I did accidentally spill some in the sink and after 30m, it congealed into what looked like that film you get on top of hot milk. It's not easy to rinse away in that state and required a good scrub.

    Overall, happy with the product! (Posted on 22/11/2015)
    Powdered Awesomeness Review by SomeMuthaFunky
    I'm a big fan of the BP whey proteins so I bought this casein as a slow burner to get me through the night. I bought the Strawberry flavour and to be honest it's very nice indeed. Like a weak strawberry milkshake. Very palatable and mixes very well so I'm not sure what was causing problems for the other reviewer. (Posted on 02/10/2015)
    Excellent Review by Josborne
    After having tried numerous slow release casein's from brands such as Reflex and Optimum Nutrition, Bulk Powders is by far the best tasting and best quality. Highly recommend strawberry flavour to all my friends and who ever asks me about a slow releasing protein. (Posted on 31/08/2015)
    Quality Product Review by Sarah
    I have the chocolate flavour which I use in a shake combined with Ultra Fine Oats and Complete Protein Blend. It mixes well, just shake it in your shaker for 30 seconds. I do not get lumps.

    I sometimes put it in the blender with some Greek yoghurt for a sweet-ish treat.

    I have been on a cut recently and it's helped me maintain my lean tissue on a calorie deficit. (Posted on 07/05/2015)
    Tastes ok, impossible to mix Review by Jay
    I can't seem to get this to mix properly. It leaves big clumps even with a shaker and really giving it a good going over!

    I have the unfalvoured stuff, considering it's unflavoured casein it's not that bad. Would be fine if they could get it to mix better somehow?? Surprised no one else has mentioned this in the reviews. (Posted on 21/04/2015)
    Excellent Value. Review by Brendan
    At 90% protein content (unflavoured version) this is excellent value compaired to Optimum Nutrition or USN which are way over priced. The unflavoured version is a very fine powder that is very sticky. Taste is ok but it is not important, you can always add a bit of cocoa powder or ice cream to it. It mixes very well as long as you give it a good vigourous shake. Best taken before bed. Overall excellent product. 5 out of 5 for quality and value. (Posted on 03/03/2015)
    Really like the strawberry Review by Dara
    This is the first protein product I've purchased that wasn't one of the many chocolate flavours you can get. (really need to expand my horizons haha) The consistency of the powder is real "flour-y" and sticky but I really like it.

    I always love to mix protein with the least amount of water I can without having lumps. To me this stuff is like having a yoghurt drink like yop. It's a little chalky but it tastes lovely. It'd be awesome if they could do expand on the range of flavours though! (Posted on 06/02/2015)
    Chocolate delight Review by Maksim
    I mix this product with 200-250 ml of room temperature milk pre-bed and it is one of the best shakes I've ever tried. I also have the Informed Whey Strawberries & Cream which I am already bored with, but with Casein every time I taste it is like the first time.

    I'm only drinking it for a month in combination with the Informed, and I can tell that they are definitely working. (Posted on 05/01/2015)
    Slept better knowing I had this Review by Gavin
    This product is great.

    Taken daily before bed leaves you feeling full until breakfast while feeding your muscles, which is great.

    If I was to say it tasted of anything I'd say porridge oats, which is great because I love porridge. (Posted on 12/10/2014)
    Mixes well tastes great Review by Aaron
    Great product, feels as though works better with milk to me, best casein product that I have found for the price by far! (Posted on 13/09/2014)
    Great. But please add a banana flavour Review by Abdullah
    It works well. It's nice etc etc, but I must admit that I've drank far too much of the chocolate and the strawberry. Please add a banana flavour. Otherwise amazing product. (Posted on 31/08/2014)
    STRAWBERRY Review by Wayne
    Upon opening i see that having it in a deep pouch is awkward, as when you stick your arm in it clings to your clothes/arms!! Be better if it came in tubs.

    The product itself is decent, 30g Casein & 20g protein mixed with milk in a BP blender then transferred into a bowl and put in fridge for a while to set, its like angel delight, bloomin' marvellous!! (Posted on 11/07/2014)
    Micellar Casein Review by Marcus
    Excellent product, you know you're in safe hands when you buy a product in this case Micellar Casein, and you read the ingredient label and the only thing on there is Micellar Casein and Cocoa Powder, then you look at the nutrition table and it states the protein at 83 grams per 100, which is 83%.

    This product is advertised as 90% protein and I have no doubt it has lost 7%'ish due to chocolate flavouring, that's pretty damn good.

    They could have put cheap cocoa in there or loads of it to keep the weight up and protein down to boost profit margins, BUT BULK POWDERS DIDN'T! I love the fact that they have no other ingredients in there, that no one's ever heard of, and that they clearly list the amounts per 100g. Excellent guys, keep it up! (Posted on 29/04/2014)
    static chalk powder Review by Liam
    I ordered the strawberry, other than it being a static chalky kind of powder with a very strange cheap taste, for the amount that I got for my money I will not complain.

    I use one scoop mixed with chocolate whey in the morning same after a workout and a double mix at night, and with chocolate whey together its a must, tastes absolutely delish! Hopefully it's as good as it says nutritionally. (Posted on 13/04/2014)
    Slightly Chocolate Flavoured Cement Review by McK
    Purchased Micellar Casein with a chocolate flavour instead of Calcium Caseinate due to Calcium Caseinate only being offered in an unflavoured form at the moment. Using it as a slow release evening/night-time protein.

    I have been taking 1 spoonful (approx 30g) for the past 10 days, so can't comment on results yet, but as for the flavour etc. imagine slightly chocolatey cement. This stuff looks like dry cement powder, tastes like how I imagine cement tastes, smells like cement and feels like cement in the stomach. No where near impossible to consume, but equally, no where near as delicious as Bulk Powders Whey range.

    I guess this is due to the type of protein, but I would like more chocolate flavour to mask the nasty after taste, however, I don't think much can be done about the "heavy" feeling I get in my stomach after drinking this.

    Note from BULK POWDERS: Thanks for your honest review McK. Micellar Casein is practically impossible to make taste like Whey. It's a lot thicker and doesn't take flavouring as well. As far as flavoured Micellar Casein products go, however, we think it's as good as it gets. The heavy feeling in your stomach is because the Micellar Casein is coagulating - this is exactly what makes it slow release. If you don't get this feeling, and it doesn't have this consistency then it's not Micellar Casein! (Posted on 11/04/2014)
    Very tasty and addictive chocolate flavour Review by Tom
    Very happy with my Chocolate casein. When I opened it, it looked like chocolate chalk because of its texture. However it mixed easily and I used 2 scoops with about 500ml water. It has a really moorish chocolate taste, as soon as I finished I wanted another! Really great before bed, think I'll go for 2.5kg after my 1kg bag has finished. Great work Bulk Powders! (Posted on 20/03/2014)
    Good Product Review by OS
    Snapped this up as a new product for before bed time shake. Got the choc flavour as I prefer flavour to unflavoured. It didnt taste as though it was chocolate, unlike the whey protein.

    Followed instructions on mixing also 1.5 scoops to 250ml, was more watery than I expected also.

    Apart from the taste and mixing, product is great with excellent nutrient info. (Posted on 11/03/2014)
