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 flavour and creamier texture, making R1 Whey Blend is a great choice for athletes who prioritize taste when choosing a protein powder.
