On a low-carb diet, protein does a lot of heavy lifting. It is the backbone of most keto meals, but getting enough without eating chicken breast at every sitting can feel repetitive. That is where a good protein powder helps. And if you love something thick, creamy and spoonable, micellar casein might become your new favourite. So what is micellar casein, and how is it different from the whey you may already know? Let's dig in.

What is micellar casein?

Milk contains two main types of protein: whey and casein. Casein makes up most of the protein in milk, and it naturally forms tiny clusters called micelles. Micellar casein is simply casein kept in this natural form.

Our Finally. Micellar Casein is 100% micellar casein, made from milk, with no added flavours, sweeteners or fillers. It is unflavoured, with a mild, milky taste, and suitable for vegetarians.

Slow and steady: casein vs whey

The big difference between the two milk proteins is speed. Whey digests quickly. Casein digests slowly: in the stomach it thickens into a soft curd, so its amino acids reach the bloodstream more gradually and over a longer time than whey (Boirie et al., PNAS, 1997).

That same thickening is what makes casein so useful in the kitchen. Mixed with a little liquid, it forms a thick, creamy texture that whey simply can't match.

High protein, low carb

Finally. Micellar Casein contains 78g of protein per 100g and just 5.5g of carbohydrates. A 30g serving has under 2g of carbs, so it fits comfortably into keto and low-carb eating.

For context, the adult Reference Intake for protein used on UK food labels is 50g a day (British Nutrition Foundation). Your own needs depend on your size, age and activity, so a registered dietitian is the best person to help if you are unsure.

Five ways to use Finally. Micellar Casein

1. Protein pudding: stir 30g into 60 to 80ml of liquid until thick, then let it set for a few minutes. Sweeten with Finally. Soft Brown or Finally. Stevia.
2. A simple shake: mix 1 scoop (around 25 to 30g) with 200 to 250ml of water or unsweetened almond milk. Shake or blend and drink straight away.
3. Thick mousse or protein fluff: whisk it with less liquid for an airy, spoonable treat.
4. High-protein ice cream: freeze a sweetened casein pudding for a creamy, low-carb dessert.
5. Low-carb bakes: replace part of the almond or coconut flour with casein to give bakes more structure and moisture.
