Man training in gym with 3 bottles products shots of RULE ONE PROTEIN

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.*

I love the flavor. Due to the tiny bits of cookie this does have a very small amount of sediment that I don’t notice in other R1 powders. *

I have been using Rule 1 Protein Isolate for years. It mixes easily whether you use water, almond milk or something else and the taste is good with no chalkiness or chemical taste. The price is reasonable and there are so many flavors to choose.*

This has been my go to protein shake for 3 years now. The vanilla cream flavor is delicious, it mixes so well. It is a low calorie, low carb mix; just what I'm needing.*

This is an okay isolate protein - chocolate fudge is not the best flavor. Good in a pinch, but doesn't mix great.*
