What Is Micellar Casein Protein Powder? Try The Best Casein Protein Shake

Australian grass fed cows, hormone and GMO free, ultrafiltered and undenatured protein

Bulk Nutrients' Micellar Casein is completely undenatured and sourced from Australian grass fed cows and dried using ultra filtration.

Micellar Casein is a protein powder that is slowly absorbed (up to 12 hours) and therefore supplies amino acids to the muscles over a long period of time. It is rich in naturally occurring branched chain and essential amino acids (BCAAs and EAAs) and can assist in the maintenance and growth of muscle.

As a slow release, anti catabolic protein powder, Micellar Casein is ideal consumed as a night protein.

Micellar Casein is an excellent option for those looking at alternates to Bulk Nutrients' discontinued Calcium Caseinate.

100% Aussie Micellar Casein Protein

Bulk Nutrients Micellar Casein is sourced locally from the milk of grass fed Australian cows. Our Micellar Casein is creamy, tasty and packed with naturally occurring amino acids that promote lean muscle growth and recovery.

Micellar Casein is great tasting, can be mixed as a shake or a mousse!

At 81.5% Protein, 1.3% Fat and 5% Carbs, it’s a great high protein shake, and it’s also delicious mixed with only 100-150ml water and a spoon of peanut butter as a dessert!

About Micellar Casein Proteins

Micellar Casein is also known as Milk Protein Isolate and is refined during the milk process. It is very high in protein and low in fats. Micellar Casein is most effective at preventing muscle breakdown (catabolism) but can also be used as a protein to build muscle.

As a slow release protein, Micellar Casein is ideal for times when frequent meals are not feasible, which makes it ideal for evening use. It is digested slowly which means there is a steady supply of amino acids into the bloodstream.

Micellar Casein FAQs

Why is Micellar Casein protein (Milk Protein Isolate) the best choice?

Micellar Casein protein advantages are due to its slow absorption qualities. It has a unique composition which means it is broken down slowly by the stomach and absorbed far more slowly than whey protein. Typically, it is called an “anti-catabolic” protein rather than an “anabolic” protein.

When should I take Micellar Casein protein?

Due to its anti-catabolic nature, Micellar Casein protein is best taken after training and just before bed.

Why is Micellar Casein protein great at night?

Its anti-catabolic nature is the reason Micellar Casein protein works so well during the night. Research has shown that when enough quantities have been consumed it will feed the body for many hours. Typically, whey protein is absorbed at around 10g per hour, with casein around 6g per hour.

What does “anti-catabolic” mean?

Catabolism is when the body breaks down its own muscle tissue for energy.

While it sounds frightening, this happens all the time as the body goes through “catabolic” and “anabolic” cycles throughout the day. “Anabolic” is the building of muscle, so by good nutrition we try to reduce the periods of catabolism where possible.

How is Micellar Casein “anti-catabolic”?

Micellar Casein largely functions in an anti-catabolic way due to its prolonged absorption. Think of it like a low GI carbohydrate, when consuming casein the body is fed a slower amount of nutrients over a longer period as the stomach breaks it down far more slowly due to its structure.

What is a standard dose of Micellar Casein?

A standard dose of Micellar Casein is 30 grams which results in 22 to 25 grams of pure, slow release protein.

How does Micellar Casein mix and taste?

Micellar Casein has a neutral taste and mixes to a thick consistency. If combined with whey it can thicken the shake and make it feel like more of a meal.

As Micellar Casein is neutrally tasting in raw form it tastes very pleasant when flavoured.

Are Whey Casein and Micellar Casein the same thing?

Yes. These names are used interchangeably by manufacturers and resellers.
