Rule1 R1 Casein Protein (4.2lbs)
Rule1® R1 Casein is a slow-digesting protein powder formulated with 100% micellar casein to support extended protein intake. Each serving provides 25g of protein, making it a suitable option for times when a sustained release of amino acids is preferred, such as between meals or at night.
This formula mixes into a thick and satisfying shake, offering a gradual release profile that makes it different from fast-digesting whey proteins. Naturally containing all nine essential amino acids, including branched-chain amino acids (BCAAs), R1 Casein helps meet daily protein needs with a steady supply over several hours.
