R1 Protein is made with super-pure 100% whey isolate, fast-acting whey hydrolysate, and virtually nothing else. R1 Protein contains no creamers, gums, amino spiking, and other fillers that dilute what you really came for – protein. R1 Protein provides little to no fat, cholesterol, carbohydrate, or sugars. The result is an industry leading Protein Purity Percentage of up to 87%. When it comes to protein powders, they don't get much cleaner than this.
 
R1 Protein is a fast acting protein and works well first thing in the morning and before or immediately after workouts to help effectively deliver the vital amino acids your muscles need for optimal performance, as well as to support recovery post workout.
