Product Information

R1 Protein Isolate

Our flagship protein is made with super-pure 100% whey isolate, fast-acting whey hydrolysate, and virtually nothing else. We’ve completely omitted the use of whey concentrates as well as creamers, gums, amino spiking, and other fillers that dilute what you really came for – protein. The result is an industry leading protein with zero sacrifices when it comes to taste.*

RULE ONE PROTEINS™ COMMITMENT TO QUALITY

Since day one, Rule 1 Proteins™ has proven that exceptional quality and superior value aren’t mutually exclusive. We develop our own products, source the finest ingredients, and manufacture them in a FDA-inspected, NSF/GMP-compliant, and Informed-Choice certified facility. Streamlining and tightly controlling every phase of the process, from start to finish, enables us to offer premium products without the premium price.
