R1 Protein delivers 25g of pure whey isolate protein to support muscle recovery and growth. Unlike protein blends that dilute potency with cheaper concentrates, every serving contains only fast-acting isolates and hydrolysates. The result is an industry-leading 87% protein purity percentage.
Why It Works
100% ISOLATES & HYDROLYSATES: No whey concentrates means faster absorption and higher protein density per serving.
6+ GRAMS BCAAS: Naturally occurring branched-chain amino acids support muscle protein synthesis.
NO FILLERS: Zero gums, creamers, or amino spiking — just pure protein that actually works.
What's Inside
Clean whey isolate and hydrolysate formula with zero sugar, zero fat, and zero artificial preservatives. Gluten-free. Contains milk and soy. NPN N/A.
Why we carry it: Rule One's uncompromising commitment to 100% isolates with transparent labeling sets the standard for protein purity.
Contains Milk and Soy
Add one (1) scoop of R1 Protein powder to one (1) cup (8oz) of cold water. Stir or blend until smooth.
Yummy, and when added to cereal with milk makes a quick start to the morning. Because it takes longer to process than other protein powders that we have used, we can walk/run for an hour without running out of energy. Great when we have to get up early and go to avoid the heat.

I take this before and after my workout. I love the vanilla creme flavor-- it tastes great and isn't too sweet or artificial tasting. The hydrolysate form seems to work better for me than the isolate form, but I like that this product has both options. It mixes up easily with water or milk and doesn't leave any clumps behind.

I think they are working on the flavor a bit because the last time I ordered it, it was much better tasting. I've tried other brands and this is my favorite so far in terms of taste and quality.
