Whey Isolate/Hydrolysate Formula

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 Purity Percentage (PPP) of up to 87%. ^ R1 Protein is protein with a capital-P.

When are the best times to use R1 Protein?
R1 Protein is a fast acting protein and works well first thing in the morning and before or immediately after workouts to help effectively deliver the vital amino acids your muscles need for optimal performance.
How much R1 Protein should I take?
It really depends upon factors such as your physical size, what your diet consists of, how many total calories you consume, and your activity level. A common rule of thumb in the bodybuilding world is to aim for 1 gram of protein per pound of bodyweight per day. In other words, a 200 lb athlete should target 200 g of total protein from all dietary sources including protein powders and other supplements.
What are the main differences between R1 Protein and R1 Whey Blend?
R1 Protein is our flagship protein made exclusively with pure, fast-acting whey protein isolates and whey protein hydrolysates. R1 Protein contains no fillers, creamers, or gums and provides little to no fat, cholesterol, carbohydrate, or sugars. When it comes to protein powders, they don't get much cleaner than this. R1 Whey Blend is also 100% whey protein, but contains a blend of whey protein concentrates, isolates and hydrolysates. The whey protein concentrates contain less protein and greater amounts of fat and carbs than isolates, but they are more cost effective. Whey protein concentrates also contribute to a richer flavor and creamier texture, making R1 Whey Blend is a great choice for athletes who prioritize taste when choosing a protein powder.

    Awesome Taste and Easily soluble in water

    I never took the protein powder. This is my first time and even for the first time also I felt I choose the best. I bought Chocolate Fudge Flavor and it tastes really good even with the water.

    Love this stuff! I've tried just about every protein powder on the market and this one by far, is the best. I like the fact that I can get it all natural and have minimal carbs in it. That's important to me as I am training and cutting carbs.

    Best tasting protein

    Posted by Margo on Jul 20th 2017

    So happy I found Rule One. Macros and flavors are incredible. Great for cooking and protein shakes. I can honestly say this has made being in a caloric deficit a bit more bearable. Perfect for anyone whether you are prepping for a show or not.

    So far tried Cookies and Cream and Salted Caramel and both taste great, but Salted Caramel is the bomb. This brand goes down real smooth. We love it!
