Rule 1 Casein Protein

Micellar casein is a milk protein with a different digestion profile and texture from whey. This makes it a useful alternative when you prefer a thicker drink or want variety in your protein routine. It contributes complete dietary protein without requiring a specific time of day to be useful.

Mix about one scoop with 300–355 mL (10–12 fl oz) of cold water, milk or your preferred beverage in a shaker. For a smoother texture, blend with ice. Use between meals or in the evening as part of your daily protein intake. The exact scoop weight and nutrition vary by flavor.

The current pack selections are approximately 26 or 52 servings. At one serving daily, they provide about 26 or 52 days of use. Your duration will change if you use it less frequently or prepare a different portion.

Amounts per full labeled serving: 1 scoop, measured to the selected flavor’s gram weight.

Calories and protein are shown per powder serving. The complete flavor panel also lists fats, carbohydrates, sugars, sodium and other nutrients.

Is casein the same as whey?
No. Both come from milk, but casein generally forms a thicker shake and has a different digestion profile.

Must I take it before bed?
No. The manufacturer suggests evening use or between meals, but it can fit another convenient time in your protein routine.

Can I mix it with milk?
Yes. Milk changes the drink’s calories, protein and other nutrients compared with the powder-only label.
