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.*

Good flavor, mixes well. R1 protein is one of the cleanest protein on the market. If you want to get away from all the other brands full of fillers and unneeded additives R1 is the way to go!*
