Supplement Mart is one of the largest muscle nation stockists, everything from their casein custard, muscle nation WPI, muscle nation greens, muscle nation vegan proteins and soon the all new muscle nation protein bars! 

Muscle Nation’s Custard is the next generation of casein proteins. Casein is a slowly digested form of milk protein that is perfect for use before bed or before prolonged periods without protein intake. Available in four delicious flavours, Muscle Nation’s Custard is best served as a smooth dessert style custard, making it a great option for the last meal of the day or for those hectic days when you need something delicious, convenient and macro-friendly.

Muscle Nation’s Custard consists of 90% casein protein, providing 27g of slow release protein per serving. This slow digestion results in a steady and sustained release of protein over a period of several hours, ensuring recovering muscles receive a constant supply of amino acids for repair and rebuilding.


Muscle Nation’s Custard isn’t just a protein powder. It contains a range of well dosed and evidence-backed ingredients to promote digestive health. Each serving contains 7g of glutamine to promote healthy gut function as well as 3g of fibre to aid digestion and help you feel full for longer. Muscle Nation’s Custard contains the highest quality of ingredients with no fillers, gums, creamers or gluten.

Muscle Nation’s Custard is available in mouth watering flavours: Banana, Chocolate Banana, Chocolate Hazelnut, Coconut Caramel, Choc Mint, Cookies & Cream, Strawberry Cheesecake and Vanilla. Each tub contains 25 servings of two level scoops. Take 1-2 scoops in a bowl, blender or shaker slowly add cold water or milk whilst vigorously stirring the mixture. Slowly add more liquid until the desired consistency is reached. Muscle Nation’s Custard is the next evolution of protein powders. Delicious taste and consistency, gut health promoting ingredients in an easy to consume, macro friendly dessert. What more could you ask for!

Couldn't by happier with Muscle Nation's Casein Custard from Supplement Mart, great tasting product and they have competitive pricing on most of their range. Shipping was extremely fast to the East-coast, and was FREE since it over $99 too!
