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.*

Mixes will, can drink with water. Flavor is on point, and doesn't have that protein smell.*

There's a #1 on the container for a reason. For me this is the best protein I've ever had and I've tried a lot of them. Flavor is right on, it tastes like it should. Mixes completely in water or milk. It has no cholesterol. Which is super important for me as I already have a elevated cholesterol count.*
