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!


  • Great taste and mixability

  • Added enzyme complex
  • Ideal for use between meals or before bed

Suggested Use

Mix one large scoop (32g) to 200-400ml of water or milk before bed. Or test your cooking skills and make some tasty high-protein pre-bed treats.

Caseine qui ne se dissous pas

Review by Felix on Mar 11, 2021
Je suis tombé sur une caséine super dense qui ne ce dissous pas. Chaque soir je dois la passer au tamis et repasser avec une cuillère dans mon shaker car systèmatiquement un dépôt équivalent à 1/3 voir presque la moitié de la dose reste au fond de mon shaker. Je perd énormément de produit. Je suis très déçu.

Was groot fan van deze gold standard caseïne, maar sinds afgelopen maand is het veranderd. Waar het eerst snel en goed oploste, lost het nu veel minder goed op! Ook de smaak vind ik minder lekker dan eerst. Spijtig

Structuur is helaas veranderd

Review by Cathelijn on Jan 25, 2021
Ik was groot fan van de creamy vanilla van deze gold standard casein, maar sinds afgelopen maand is het productieproces veranderd. De producent noemt het 'verbeterd', maar daarover verschillen we van mening. Waar het eerst snel en goed oploste, lost het nu veel minder goed op! Ook de smaak vind ik minder lekker dan eerst. Jammer!

Goede Shake

Review by Amanda on Jan 22, 2021
Ik had vanille en chocolade besteld. Chocolade vond ik super, wel meer mocha smaak dan echt chocolade. Vanille vind ik echt super chemisch zowel qua smaak als geur. Vond de vanille zeker geen aanrader. Zou daar 1 ster voor geven. Het is dat de chocolade smaak dat weer goedmaakt. Verder gooi ik het in mn blendjet en laat ik het even staan dan mengt het goed.
