Product Description

Casein is a dairy protein that is slowly digested by the body. This is due to the formation of a clot inside the stomach, which will take longer to be digested. Because of the slow release, this type of protein is ideal to be ingested before bed or throughout the day when you go for long periods of not refuelling the body.  Muscle Nation has crafted a casein protein, which is made of 90% casein and concentrate delivering 25.2g of complete protein to the body. Custard Casein Protein has no filler, gums or creamers so you can rest assured you have a high-quality product.  Sprint Fit loves the taste and feels like a guilt free treat. 

Muscle Nation Custard Casein Protein features:

  • Support calorie processing. When you combine this product with the right diet and exercise plan tailored to your fitness goals, you will see better results. 
  • Support body composition goals by providing the body with slow-release protein so you can refuel the body with the right nutrients for an extended period of time.
  • Have a slowly digested product as casein takes longer to be digested by the body, making this product great to be taken before bed or throughout the day.
  • Consume a high protein and low fat and carb product ideal for when you are watching your calorie intake.

I ordered some Atkins products. Brilliant service from sprintfit, no hassle order next day delivery. The next time I need to order it will be with sprintfit. Better service and same price as Woolworths supermarket.

I think the vanilla custard is so-so but I love to make an oat bake with the cookies and cream. The choc is good whipped with frozen banana. Finally got the golden ice cream and it's really good as a custard! So happy, please always sell this product! It's the easiest protein to consume.

10/10 Golden Ice Cream

OBSESSED - I never thought of trying out the custard until one of my friends brought it into work O M G - this is life changing, can have it warm or cold with frozen berries OR even add a scoop to your protein shake (to make it thicker) with some ice, almost like a ice cream thick shake!!! Have tried 2 flavours but must say Golden Ice Cream is 100% the bestest! + has little cookie bits. 10/10 !
