Rule1 R1 Casein Protein (2lbs) Rule1® R1 Casein is a slow-digesting protein powder formulated with 100% micellar casein to support extended protein intake.

This formula mixes into a thick and satisfying shake, offering a gradual release profile that makes it different from fast-digesting whey proteins.
