Product Info

Sometimes slower is better - especially when it comes to the rate of protein digestion. While rapid protein absorption is desirable immediately before or after exercise, delayed release is probably more beneficial throughout the remainder of the day.

Casein proteins found in Optimum Nutrition 100% Casein Protein are pH sensitive and gel in the acidic environment of the stomach. As a result, it can take more than twice as long for caseins to be broken down into their amino acid subcomponents than whey and other proteins. Because of their unique time-released qualities, caseins are aptly described as anti-catabolic or muscle-protecting proteins.

• 24 g Instantized Blend of SLOW-DIGESTING CASEIN-Based Proteins
• Rich in Highly Anti-Catabolic MICELLAR CASEIN
• Over 9 g of BCAAs, Glutamine, and Glutamine Precursors per Scoop

great product
Review by Larry (8 April 2014)
gained really solid muscle while using this a my bedtime shake. bit pricey but real value for money
Delicious and high quality protein powder
Review by Ania (13 December 2013)
Casein powder is amazing for baking and making protein fluff, and of all the casein powders I've had, ON makes the best tasting of the lot. Great for bulking and great for keeping you full for a long time. Yeah, it's a bit pricey, but ON is one of the most trustworthy brands in the game, so you know that each tub will contain what's advertised.
The best

Never have I had a better alternative to Pudding before i go to bed!!
Review by Yeskiel (9 October 2013)
The best casein on the market.Fuels your muscles as you sleep resulting in good recovery and muscle gains
Very good before bed
Review by Chad (20 January 2013)
Your body only has enough protein in it for about 6-7 hours while you sleep, when it runs out, muscle catabolism kicks in and you start losing muscle mass. Casein protein stops that from happening. It creates a protein 'drip effect' and feeds protein into your muscles for about 9 hours to stop you from losing muscle mass and you wake up without that burning hunger sensation that a lot of gymers like myself wake up with.
Best I've used
Review by Renzo  (26 November 2012)

Brilliant Product
Review by Dinko9 (14 September 2012)
I've gained some solid muscle using this product. The taste is amazing. Blend a cup of ice, Greek yogurt and a scoop of this together, heaven!
Just what you need!!
Review by Kyle  (1 August 2012)
With my busy lifestyle, i only eat supper after 9pm every night. which is not good!!! But as soon as i got me some of this stuff. Its one shake, then I'm full and ready for bed, and keeps me full till morning. This stuff is really the best!! Recommend it!!
Good casein protein
Review by Yn (3 May 2012)
Just like the whey, it mixes and tastes great. Its ideal before bed and you can even blend it with the whey for optimal fast and slow absorption.Price is way out though when compared to S.A market.
One of the best
Review by Tee (15 February 2012)
It has great taste and u get results body wise
Important if youre bulking
Review by Dominic (12 February 2012)
Tastes amazing especially cookies and cream. I took it right before bed as your body can utilize this slow release protein to repair muscle during the normal nocturnal repair cycle. I did observe muscle gains on it. Awesome product. Trustworthy.
Best Casein
Review by Ari (31 December 2011)
Optimum is known for creating the best Protein powders and this is no different. Far better than the local brands in quality and tastes great to.
the real deal
Review by Matt (4 July 2011)
Mix this with organic milk pre bed for a great slow release formula. This mixes just as a good casein should - sludge like. It almost has a texture similar to custard. Really good product that I can trust. I have also taken Evox casein , not bad but I'm not sure its as good as this. If you can spend the few extra bones then definitely purchase ON.
Better than a milo
Review by Jared (21 June 2011)
I find that I have managed to stall mass loss a bit with this. I find it hard to maintain mass. The taste on the chocolate one is AMAZING and it is really nice and thick and creamy mixed with a shaker and a block of ice.
Guilt-free desert

Great Stuff
Review by TK (3 May 2010)
Mixed with milk, this is a great tasting shake just before going to bed. It keeps my hunger pains down when I wake up in the morning and keeps me in an anabolic state while I sleep.
Review by Jolly (16 April 2010)
