Product Info

  • 24g of pure micellar casein protein with only 0.5g fat & no sugar
  • Slow digesting protein powder
  • Supports muscle growth & maintenance

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 & especially last thing at night.

Optimum Nutrition Gold Standard 100% Casein Powder is the industry's first all-micellar Casein, and delivers 24g of slower digesting casein proteins for muscle growth support. Casein is best enjoyed in the evening - simply add one scoop to water, milk or your favourite drink.


Add one scoop of Gold Standard 100% Casein to 300 - 350 ml of water or prefered beverage. Use first thing in the morning, immediately before bed, in place of small meals, and/or any other time when delayed protein absorption is desired. To make protein ice cream, just mix one scoop into half the amount of water you normally use (150-180ml), place in the freezer for about 5 minutes - then enjoy!


Micellar Casein (milk) [contains Emulsifier: Soy Lecithin], Fat-Reduced Cocoa Powder, Flavour, Salt,Thickeners (Cellulose Gum, Carageenan Gum, Guar Gum), Sweetener (Acesulfame Potassium, Sucralose), Enzyme Complex (Amylase, Protease, Cellulase,Beta-D-Galactosidase, Lipase).

Customer Reviews
Optimum Nutrition Gold Standard 100% Casein Powder Chocolate is rated 4.3 out of 5 by 9.
Rated 3 out of 5 by from Chocolate Arrived promptly and was what I ordered. Consistency is a lot thicker than whey protein. The taste is not great and I would try another flavour. Was hoping it would taste like chocolate milk but has weird aftertaste. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Brilliant protein Too early too talk about results as I just started taking this powder - regularly take lean whey so will see what the combination will bring. The taste is amazing like a Nesquik cacao powder, when mixed with water tastes like a souffle.

Rated 5 out of 5 by from Perfect evening supplement i prefer to cycle my use of supplements so I use whey & casein proteins as well as creating and BCAA's when I'm pushing it and just use s balanced diet when trying to reduce fat and water retention. Casein protein is always a favourite for evening/bedtime supplements and I certainly felt improvements in growth and repair. bottom of my list of importance is flavour but you can't go wrong with this for taste when mixed with water.

Rated 4 out of 5 by from Amazingly good, but expensive! It is truly the most amazing thing I've ever tasted when it comes to chocolate overall, wheather we're talking about protein shakes, or chocolate bars! When my friends have chocolate pudding, or cake, or any other dessert - I have this with some strawberries, a banana, or just plain. It's DELICIOUS!

Rated 4 out of 5 by from Mixes very well but not as tasty as whey protein. Easy to mix to a smooth consistency but tastes rather plain.
