Important Information


Casein is best taken at night, as this is when the majority of muscle rebuilding takes place. Simply add one rounded scoop to 300-360ml of water, milk or your favourite drink in an ON shaker half an hour before bed.

Product Description

Product Description

Optimum nutrition 100 percent casein protein banana powder 1.8 kg offers the slow-digesting protein essential for facilitating muscle recovery and preventing muscle breakdown. Rapid-protein use is desirable immediately before and after exercise to help refuel recovering muscles. However, delayed digestion and absorption may be more beneficial at other times, including bedtime, when your body typically goes for hours without food. Casein proteins are acid sensitive and thicken in the stomach. Because of this, it can take more than twice as long for Optimum Nutrition Gold Standard 100 percent Casein to be broken down into its amino acid subcomponents than other proteins. The industry's first all-micellar casein provides sustained-release amino acid support.


Protein blend (micellar casein, calcium caseinate), cocoa(processed with alkali), natural and artificial flavors, salt, gum blend (cellulose gum, xanthan gum, carrageenan), sucralose.

Bad Taste. 14 Oct 2008
By Hal Sullivan - Published on Amazon.com
It's hard to come across a good tasting casein product. This flavor is no exception. It's way to sweet and has only a tiny taste of banana. It's a real chore chugging this before bed. I can't wait till I finish this tub to buy ON Chocolate (which I hear is pretty good).

lumps 27 Mar 2008
By R. J. - Published on Amazon.com
Verified Purchase
tastes bad,mixes even worse. no matter what,there will be lumps. even if you use a blender ther will still be some irritating lumps.I tried to heat up the water a bit and it mixes better, but smells bad and i read somehwere that it messes up the proteins.
Again, this does not remotely taste like banana, more like some chemical taste.
