Optimum Nutrition Gold Standard 100% Casein Powder Chocolate 924g

€54.00

  • 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.

Full ingredients

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). For Allergens - See ingredients in bold.

Directions:

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!

Nicest chocolate protein powder

Second time buying this. It's the nicest chocolate protein powder I've had. I mix it with 200g greek yogurt and a few dark chocolate chips for an evening snack and don't find it lumpy at all. Keeps you full all night so you don't wake up starving the next morning.
