Premium micellar casein protein powder

Optimum Nutrition’s premium high-quality micellar casein powder is packed with 24g of slow digesting protein per serving, specially designed to help grow and maintain muscle mass. Enjoy before bed to help reach your fitness goals or achieve the perfect body tone and shape. Gold Standard 100% Casein also has an added enzyme complex and comes in a range of tub sizes and flavours, depending on your needs.

High quality protein best consumed before bed

Micellar casein protein is the industry gold standard, slow-digesting protein that contains all nine essential amino acids. Casein works best during periods of long duration between protein intake, either before bed and during the day, when you may not eat for a prolonged period of time. To top it off, Optimum Nutrition Gold Standard 100% Casein is low in both sugar and fat.

Create your own tasty high-protein deserts

Gold Standard 100% Casein is available in a range of tub sizes depending on your needs. With a slightly thicker texture than whey protein, casein still tastes great and is the ideal protein to use in your own cooking - especially when making tasty, high-protein desserts!


  • 24g of high quality slow digesting micellar casein
  • Supports the growth and maintenance of muscle

Review by Stéphanie on May 10, 2020
Très bon goût chocolat , cale bien mais consistance dont je ne suis pas fan.

Helemaal niks

Review by Maxime on Feb 17, 2020
Lost niet goed op, blijft altijd een beetje poederachtig smaken. Vanillesmaak is erg chemisch en proeft eerder naar banaan.
