The first rule in bodybuilding is Input = Output. Rule 1 Protein is a superior protein that includes the nutrition you put into your body to create the perfect protein supplement. That's why R1 Protein contains one of the purest, most rapidly digested fuels around to help build and repair muscle. And with virtually zero lactose, sugar, fat, or cholesterol, it's the most complete muscle fuel to add to your routine. 

When To Take Rule 1 R1 Protein

R1 Protein is a high-quality isolate, which means fast absorption, meaning it is best taken immediately after a workout. Resistance training is one of the main promoters of muscle protein synthesis, meaning the faster we can get the protein into the digestive system, the better chance our body has of making the most out of the muscle-repairing nutrient. 

Rule 1 R1 Protein Dosage

The dosage for Rule 1 Protein is simply one scoop. This measures to 29.2g of powder, 25g of which is protein (85%) This is a standard amount of protein, however the amount that will suffice for you will vary from person to person. For example, a 100kg male who participates in regular resistance training may benefit from a scoop and a half per shake. A general rule of thumb is 0.4g of protein per kilogram of body weight for your optimal protein intake per sitting. 

Rule 1 R1 Protein Best Flavours

One of the reasons Rule 1 Protein has become one of the best-selling proteins on the market could be attributed to its large range of flavour options. From Pavlova Cake, to Choc Peanut Butter and White Choc Raspberry, there's a flavour to excited everyone. If you're wondering what are the most popular, here they are:

  • Lightly Salted Caramel
  • Choc Biscuit
  • Vanilla Creme
  • Chocolate Fudge
  • Choc Hazelnut
  • Cookies n Creme

Benefits & Results of Rule 1 R1 Protein

Trainees will benefit most from Rule 1 Protein's fast absorption as a perfect post-workout shake for increasing the rate or recovery meaning for decreased DOMS (delayed onet muscle soreness) and allowing the body more opportunity to re-build, making the most out of your workout.

Rule 1 R1 Protein Highlights

  • Each serving contains over 6 grams of BCAA's
  • Added Glutamine for Improved Muscle Recovery & Immune Support
  • Packed with Instantised Micro-filtered & Ion-exchange Whey Protein Isolate
  • Rapidly Digested & Assimilated
  • Pure Whey Protein Hydrolysate featuring Ultra-Segmented Isolates
  • Carefully Blended & Packaged in NS GMP Facility in the USA 

Rule 1's flagship protein is made with super-pure 100% whey isolate, fast-acting whey hydrolysate, and virtually nothing else. It is completely omitted with 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.

    Over the years Rule 1 have added many exciting new flavour options to their protein powders. Their Lightly Salted Caramel has remained one of the biggest fan-favourites however its hard to not get excited about the Choc Biscuit, Pavlova Cake or Red Velvet.

When your goal is to build lean muscle, a high protein intake is important - some suggest a gram per pound of bodyweight (or approximately 2 grams per kilo.)

  • Does this cause bloating?

    High-quality isolates such as R1 Protein tend to cause zero to minimal bloating being low in lactose as well as having no gums or fillers.

This is a great protein powder. It’s relatively easy to digest for those with sensitive stomachs, it’s flavoursome to the point where it tastes okay even with water and it obviously very lean. Overall a great product. You get what you pay for.

I have been using this product for a couple of years now and have found it ticks all the boxes for what I am striving to achieve.
I don't usually use a pre work out however I found the Incinr8 to provide me with a noticeable inrease in energy without the giving me a skin tingling effect. Very happy with both products.

Have tried a few different immediate post-workout whey powders before, and this is now my favourite, have only tried choc-fudge so far, but will try others soon. Goes into a smoothie with a banana, berries, creatine and oat milk.
