Custard Casein from Muscle Nation is easily one of our best selling products to date. It tastes amazing, its smoother and creamier than we could have ever imagined, and each scoop is so lean and high in protein that we literally can’t fault the formulation. Whether you’re cutting, bulking, or just looking for a quick and healthy solution for a high protein treat, Muscle Nation Custard Casein is your go-to. When it comes to helping you feel full all day, keeping your muscles fuelled for growth, and actually enjoying the taste of your protein, it doesn’t get much better. So go ahead, pour it over your apple crumble, mix it into your morning smoothie, or mix it up in 30seconds at work - either way we know you’ll love it legends!

  • Impressive macronutrient profile: High in Protein, Low in fats and Carbs
  • Slow release protein perfect to keep you feeling fuller for longer
  • Delicious taste and consistency! Think smooth creamy custard, that tastes like real custard, not protein!
  • Perfect for those who prefer eating to drinking

Obviously there are a lot of proteins. So let’s talk about what makes Custard Casein unique and different. Casein Protein is known for its slow sustained digesting effect. Therefore, unlike Whey Protein Concentrate and Isolate which are ideal for post workout shakes to get the protein nutrients in as soon as possible, Custard Casein is ideal for keeping you feeling full and satisfied throughout your non-training times, and keeping your muscles fuelled to grow and recover optimally. This makes Custard Casein the perfect snack for Breakfast, for a between meals snack, or for a nighttime dessert option.  

Per serving of MN Custard Casein, you get a lean protein, that is incredibly generous in protein content too! Each serving contains 27g of protein, alongside low amounts of carbohydrates (4g) and fat (1.8g). This makes Custard Casein an incredibly lean option, that works with you, rather than against you, in achieving you health and fitness goals. The protein within Custard Casein is responsible for providing an extended release of nutrients to your body during muscle protein synthesis - the process of your body recovering and rebuilding to increase your muscle mass and reduce your muscle soreness.

Custard Casein is also enhanced with added ingredients to support digestive health, immune system, muscle growth and overall, a healthier system. and promotes a healthy gut. This includes Glutamine, which is an incredibly important amino acid within your body. Glutamine plays a vital role in muscle recovery, repair, and regrowth - being the most abundant amino acid in the entire body. Glutamine also aids in gut health, and in the boosting of your immune system too. 3g of fibre is also added, to assist in keeping you feeling full and further promoting optimal gut health. Finally, comes the MTC Oil Powder - a source of healthy fats with potent health benefits. MCT Oils promote a healthier gut environment, aid in better digestion, improve cognitive function and even have some metabolism boosting properties! MN Custard Casein really is full of powerful ingredients!

Equally as important as what IS in Muscle Nation’s Custard Casein - is what ISN’T. There are no added creamers, gums or fillers within Custard Casein. The Muscle Nation Custard Casein Protein is also Gluten Free, non-GMO and digests very well - causing no stomach discomfort. Instead, you get nothing but premium quality ingredients to create a protein that is going to work with you - to keep you full and happy with your diet, recovered and fresh each time you go to the gym, and able to put on the lean muscle mass that you’re chasing too!

Why use Casein Protein?

Casein Protein is known for its slow sustained digesting effect. Slow digesting casein custard makes a perfect breakfast, snack and night protein option. Slow digesting casein protein will make you feel fuller for longer and can provide you adequate amount and sustained release of protein (amino) supply throughout the day / night.

Muscle Nation 100% Whey Protein vs Casein Custard Protein - what’s the difference?

Awesome question legends! Muscle Nations’s 100% Whey Isolate Protein contains just that - 100% Whey Isolate. This is an ultra filtered version of Whey Isolate, and thus contains a leaner profile (only 2.7g Carbs + 0.4g Fat per serve), a higher protein content (76.4g per 100g) and a faster digestion rate to provide your muscles with the required nutrients sooner. In contrast, Muscle Nation’s Casein Custard Protein contains Casein Protein. Casein, while still derived from milk like whey, is a slower digesting protein. It is also not as filtered as whey: thereby not being quite as lean (7.5g Carbs + 2.5g Fats per serving) and not at dense in protein nutrients (62.5g per 100g). Therefore, each protein has it’s own time and place! In a strict diet and as a post-workout shake - 100% Whey Isolate is best. As a full-feeling snack or a night-time protein - Casein Custard Protein is best.

How do I make my Casein Protein Powder into Custard?

All you need is a little water! (However, you can use milk as well if you like). To ensure the consistency is to your liking, start by adding 90-100mL of cold water or milk to the mixture while stirring (for 2 scoops - 40g). Then slowly add more water or milk if a thinner consistency is desired. Ensure the powder is mixed through completely before adding more liquid. This is totally optional - but we would also recommend trying Casein Custard Protein warm! Microwave the mixed custard for 30 seconds for a warm treat!

A serving size of Custard Casein Protein is generally 2 scoops (40g). However, you can definitely adapt this serving size to suit your personal goals and macronutrient requirements.

To mix up you Custard Casein Protein, add a serving of powder to a bowl. Start by adding 110mL of water or milk, and stir through. Then, slowly add more water or milk until you achieve your desired consistency. Always ensure the powder is mixed through completely before you add more liquid! No one likes much-too-runny Custard Casein Protein.

From there, you can get creative! Eat as-is for a simple and tasty custard treat. Alternatively, you may like to heat your custard up in the microwave for a warm custard (just like what you pour over pudding).

You may also like to add toppings. We have a number of recipes and recommendations suggested over our Blog, YouTube Channel and Instagram Stories - so be sure to check some out!
