Rule One’s R1 Protein Whey Isolate is a flagship, high-purity protein powder made entirely from whey isolate and hydrolyzed whey, without concentrate or any other sources. It has a natural version that previously came in just two flavors, both traditional in Dark Chocolate and Pure Vanilla, packing 25g of protein per serving. R1 Whey Isolate is one of the brand’s more premium entries in the competitive category alongside the likes of Casein, Source 7, and Clear Isolate.
The brand has now introduced a third option for the natural variant of R1 Protein Whey Isolate, offering the most straightforward solution possible in Unflavored. The plain alternative packs 25g of protein, a gram of carbohydrates, zero sugar and fat, and only 110 calories. The protein is still entirely from whey isolate and hydrolyzed whey, and it’s free from sweeteners and flavoring.
The all-new Unflavored Natural R1 Protein Whey Isolate option is available in 1.5lb and 4lb tubs, and it actually has a bit more value compared to the other flavors, thanks to the smaller 29.5g serving size. It results in two more servings in the 1.5lb next to Dark Chocolate, and six more servings in the larger 4lb, which is great if you throw your protein in smoothies and don’t rely on taste.
