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.

    Consistently great, one of my favorite flavors, always mixes well, and always easy on my typically sensitive stomach. Best protein powder hands down!

    Rule 1 Protein

    Posted by CC on Apr 18th 2018

    Protein is on my A list. I have taken many powders in the last 30 years and Rule 1 is very light and causes no bloating or gas which I have experienced with some.
