Clear selection

Reflex Nutrition was one of the first companies in the world to introduce Micellar Casein as a pure unadulterated protein supplement to the market back in the 90’s. During the time since the quality of the product has improved along with the flavour and mix-ability, today it is one of the “Go To” time release protein powders.

Quality Comes First

We insist in only using EU grass fed milk as the starting material. We do not favour milk or whey products from the USA because of the widespread use of growth hormones and antibiotics. Quality at Reflex Nutrition is of absolute paramount importance. We can never stress this enough, we only manufacture the best of the best and that dictates only using the best ingredients available.

Our Micellar Casein does not contain any other types of added protein, especially soy, added glycine or anything that would water the product down. As a result it delivers more protein per 100 grams than nearly any other time release protein on the market today.

The process involved to make this valued and sought after protein powder employs a state of the art ultra filtration process that is carried out at low temperature to capture every single valuable milk protein in its native form whilst carefully filtering out unwanted fat and sugars. The resulting protein powder is exceptional, delivering both pure undenatured Native Micellar Casein and Native Whey Protein in an 80:20 split per 100 grams.

It’s a Slow Release Protein, Contributing to Growth and Maintenance of Muscle Mass

Micellar Casein is used extensively by individuals wanting to take full advantage of its slow release properties. It is slowly digested by the body steadily releases amino acids into your blood stream. It’s therefore the perfect shake before bedtime or during extended periods between meals where it drips feeds your body for up to 6 hours.

Improved flavour and mix-ability

Using new flavour technology we have improved the flavour of Micellar Casein dramatically without resorting to adding sugars, corn syrups or creamers. The focus as always is to deliver a product that mixes easily in a shaker and delivers a very satisfying shake.

Additional Product Information

Micellar Casein is a form of milk protein, which has been proven to breakdown slowly over a longer period of time when compared to other protein supplements such as whey protein. The benefit is that the protein can take up to 7 hours to completely digest and be utilised, making Micellar Casein the perfect protein product to use when you cannot have access to protein for an extended period of time. Because of these benefits, many athletes will use Micellar Casein prior to sleeping to maintain a state of muscle support whilst they are sleeping.

Micellar Casein from Reflex Nutrition is not to be confused with acid casein or caseinates which are made using manufacturing processes which can denature the protein rendering it less valuable from a nutritional perspective.

And just to prove that we deliver on our label claims, all of our protein products are tested in our in house protein testing facility and the results are published on our website. We also have batches randomly rest by independent, ISO accredited laboratories.

Amazing range of flavours and sizes – Micellar Casein now comes in a huge and improved range of flavours and sizes to suit just about everyone. You will be amazed just how easily they mix and how good they taste. More importantly we hope you’ll notice the significant improvements we have made to this highly acclaimed product.

Mixes well and does not taste chalky like some of the other brands, sits really well as a night time protein. Using this with 100% whey as my daytime protein. Love them both!
