Naturally Flavoured & Sweetened


100% Whey Isolate / Hydrolysate Formula Naturally Rich in BCAAs

    • 25g of protein per serving

    • ZERO concentrates, ALL Isolate formula

    • Each single scoop serving delivers approximately 3.1g of leucine, 1.8g of isoleucine, and 1.6g of Valine

    • Over 6g+ of naturally occurring BCAAs and over 4g of naturally occurring Glutamine/Glutamic Acid

  • NO gums, creamers, fillers. NO amino spiking!

R1 PROTEIN delivers two of the purest, fastest and most naturally BCAA-rich sources available. How pure? So pure that over 80% of the calories in each serving are derived from protein, leaving no room for sugars or fillers.


A great addition to the Rule One family, R1 Protein—naturally flavored! Same great Whey Isolate/Hydrolysate formula but now offered naturally flavored! To make a good thing even better, R1 Protein Naturally Flavored is sweetened with stevia and monk fruit!
