Muscle Nation Protein (Custard, yes Custard!)

Let’s look at Muscle Nation protein supplements (including their famous custard): the range, their nutrition profile, and why you might give them a look-in. What’s Muscle Nation? It’s a popular and rapidly expanding Australian activewear and nutritional supplements brand. It differs from many alternatives because Muscle Nation, a Brisbane-based family business, has built a fanatic community and culture unlike any other.

Muscle Nation Team

Fast Growing

Nathaniel Anthony and Chris Anastasi, close friends, started Muscle Nation in 2016 from a spare bedroom. Today, their orders are prepared in a 1,700 sqm warehouse in Brisbane and sent to eager customers all around the world.

Muscle Nation has quickly established itself as a well-known and renowned brand, not just in the Australian fitness apparel and sports supplement industry, but also in the broader health and fitness industry. Perhaps the thing that sets Muscle Nation apart from the rest is the cult-like devotion of “MN” customers. Further down in this article, you’ll see how their customers describe the experience of joining the growing fanbase.

Muscle Nation’s Protein Supplements

As we’ve described elsewhere, protein is essential for effective weight loss and muscle gain, and one of the easiest ways to get more of it is to take a good supplement. Protein not only helps with cell repair and muscle growth, but it also affects appetite and satiety hormones, making you feel fuller for longer.

Muscle Nation’s protein supplement products are available in vegan and gluten-free varieties for people wishing to boost their daily protein intake. They are beneficial to both men and women’s muscular growth and rehabilitation. You can take one any time of day, but especially before or after workouts, and can even be used in baking. Just be sure to include them in your daily calorie tracker!

Muscle Nation Custard

Muscle Nation Custard Protein

Custard! Yes, custard! Custard Casein Protein by Muscle Nation is a premier protein supplement produced with high-quality ingredients. It contains casein protein, which keeps hunger away thanks to its “slow-burn” digestion cycle.

Custard Casein Protein is easy to prepare and requires only water or milk. Casein protein is absorbed more slowly than whey protein, thus it takes longer to digest (keeps you feeling fuller for longer). It is a good choice for a morning meal because it sustains satiety through the critical mid-morning impulse-eating phase.

MN Whey Isolate

Which Whey?

Whey protein, on the other hand, is an excellent choice around exercises because it is quickly digested and absorbed by your body. Custard Protein is a versatile protein. You may add it to your oats or yoghurt for a protein-rich breakfast or snack, or to your favorite healthy baking dishes to boost your protein consumption. You may even use it as an icing on your dessert masterpieces if you’re feeling adventurous. 

Gluten-free protein supplements make up most of the Muscle Nation’s Custard Casein Proteins. 

Custard Protein, like the bulk of Muscle Nation food and supplement items, is made in a cGMP (current good manufacturing practice) and HACCP certified facility in Australia.

Muscle Nation Protein Flavours

Wide range of Flavours

The flavour of MN Custard is almost universally praised, with many customers comparing the experience of eating it to actual dessert custard. That might have something to do with the wide flavour selection, which ensures something for everyone:

  • White Chocolate
  • Double Chocolate
  • Vanilla
  • Choc Mint
  • Strawberry Cheesecake
  • Choc Hazelnut

Muscle Nation Protein Ingredients

So, what’s in Muscle Nation custard? Let’s delve into the ingredients list to see what sort of nutrition we can get out of each scoop:

25-27G Protein

It has a high protein content (25-27g per serve) and low carbohydrate and fat content, as well as additional nutrients that support digestive health and maintain a healthy gut.

Glutamine, 6.5-7 G

To help boost your immune system, improve digestive health, increase muscle growth, and reduce muscle tissue degradation.

Dietary Fibre 3G

Keeps you fuller for longer, boosts gut health (supports healthy bowel movement), assists in blood sugar stabilization, and lowers sugar cravings.

Powder of MCT Oil, 1.6 G

Promotes intestinal health (by killing off bad bacteria), aids digestion, enhances cognitive function, and includes antioxidants.

So, the ingredient list is pretty much what you would expect from any high-quality protein supplement, but the devil as always is in the details. The key ingredient is the protein, but what sort of protein is it? This is where Muscle Nation reveals its bodybuilding culture and origins:

What is Muscle Nation Protein?

You get two main protein options from Muscle Nation: whey (animal) and plant protein.

Whey Protein

Whey Protein Isolate (WPI) from Muscle Nation is noted for its high protein content per serving and low carbohydrate and fat content.

This protein powder has a light/ smooth texture and consistency that is great for anyone searching for a fast-digesting post-workout protein or someone who wants to increase their daily protein intake.

Most, but not all, Muscle Nation protein supplements are gluten-free, so you need to check your chosen flavour to see if the product meets your dietary needs.


  • Low Carb, Low Fat
  • 25.8g protein per serve
  • 7.4g BCAAs
  • 5.6g Glutamine
  • Gluten Free
  • Non-GMO
  • Contains under 1% lactose

Plant Protein

If you are a vegetarian or vegan, you’ll probably want a plant-based protein powder rather than dairy-based whey protein. Muscle Nation’s gluten-free plant-based protein powder is a viable solution for anyone wanting to up their daily protein consumption without consuming animal product.

Adding plant-based protein powders to your diet is a quick, pleasant, and healthy way to boost your protein intake. They’re also rather easy to digest, making them a good choice for folks who are lactose intolerant or have stomach issues while eating animal-based proteins.

Plant-based protein powders are also excellent for people seeking a more environmentally friendly and sustainable alternative to animal-based products.

Love Muscle Nation!

The custard protein is something out of this world – Well done guys for creating such an epic supplement. Custard bars are top notch too. Wish they were more easily accessible to us here in NZ. Though in saying this, the shipments are fast and efficient.

Muscle Nation never disappoints!

I have supported Muscle Nation for many, many years now and I have never been disappointed. I am in love with everything they provide. Their community is so supportive – which is one of so many reasons why I will always support them. Thank you for everything!

3 Day Delivery to Ireland!

I purchased four whey isolate protein products in the stack and save option. I am from Ireland and ordered on a Thursday and had them on the following Monday. To be honest i couldn’t believe it. I normally use a UK supplier and they take 7-10days minimum so was delighted. The mint choc is my fav and i would 100% purchase again. Muscle Nation is now my supplier of choice!

Amazing Custard

I love MN custard products as it’s VERY versatile. Whether a snack or a meal or a dessert ingredient it gives me energy, stops cravings, and keeps me full between meals. Easy to order, great range of flavours, reasonable prices, and fast delivery.
