100% Casein Protein

SLOW-ACTING PROTEIN
While rapid protein digestion is desirable immediately before or after exercise, slower digestion is more appropriate for between meals and right before bed. Compared to whey, it can take significantly longer for micellar casein to be broken-down into its amino acid subcomponents. ON's Gold Standard 100% Casein was the first all-micellar casein and remains the best seller.

This slow releasing protein is by far the best night time protein on the market. As many others I'm sure, when dieting I get very hungry during the night and getting up and stuffing my face just isnt an option. Gold standard casein protein keeps me full throughout the night and Im so grateful of the amazing taste, chocolate ofcoarse.

This stuff is the best! Mix a scoop of this with a glass of 1% milk and a little bit of Ovaltine and I can drink it all day.

This is such a great addition to your diet. I used to do straight up cottage cheese every night, but after a while I couldn't stand the taste anymore. After I stopped eating cottage cheese I started to plateau also and realized how great casein protein is. I started taking the Optimum casein because of my success with their whey and have had great results. I've been having a scoop nightly for about 2 months now.

cookies and cream taste great, but im sure every flavor is amazing, for a casein protein its mind blowing. great job on, it goes great in ice water like a pudding.

I disagree that ON Casein does not taste good in water. If I am not using Pro Complex before bed, I am using ON 100% Casein. I make it with ice water, and make it like a pudding. I look forward to going to bed early every night just so I can have my Casein. I want a lifetime supply of this stuff, just incredible! ON hits it big again.

I'm halfway done with my 5lb tub of casein and it's been great. I mix my whey with the casein during the daytime, and drink a casein shake before bed. It tastes great in 1% milk (not so great in water though). These casein shakes fill in the void in my diet that left me going to sleep hungry.
