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.

Goeie eiwitten

Ik neem deze eiwitten na het sporten voor het slapen. Deze smaken goed en geven een verzadigd gevoel.

Top smaak

Review by Carin on May 10, 2023

Effect is nog niet merkbaar want ik gebruik het nog maar net, maar de smaak en substantie zijn erg goed. Enige nadeel is de enorme verpakking: Twee keer zo groot als de inhoud, niet bepaald duurzaam en ook zeker niet handig voor in de keukenkast!

Ik drink 's avonds casein eiwit voor het slapen gaan en daardoor houd ik het langer vol voor intermittent fasting icm weight lifting . De smaak aardbei is verfrissend & romig, ik meng het alleen met water. Het lost goed op! Een blijvertje!
