The American company, also marketed as Rule One Proteins (R1, Rule 1), was founded in 2014 by brothers Mike and Tony Costello, who owned the Optimum Nutrition brand. The founders had many years of experience in the sports nutrition industry and a clear understanding of the "quality standard" of products.
Rule 1 offers a range of quality protein supplements: Classic Whey Blend (Concentrate, Isolate and Hydrolyzate), Flagship Protein with Whey Isolate and Hydrolyzate Only, and Slow Release Micellar Casein. In addition to protein formulas, the brand's assortment also includes gainers, multivitamins, pre-workout supplements and other supplements.
On the question of quality
Rule 1 Proteins brand products are manufactured in an NSF-GMP-certified facility - Nutrivo, LLC. Manufacturing facilities are located in Aurora, Illinois. The site uses new equipment for mixing, measuring, packaging and transporting R1 products.
The company cares about its products, therefore, when looking for sources of raw materials, purity and quality are primarily of interest, not price. Only ingredients that pass Rule One Proteins' strict standards for safety, quality and potency are considered. Proven branded ingredients such as CarnoSyn®, Nitrosigine®, Infinergy ™, HydroMax ™ and TeaCrine® are also preferred. These ingredients are incorporated into R1 formulas to provide the results consumers expect.
Rule 1 Proteins mission
R1 products are used by thousands of athletes, among whom they themselves founded. The question of quality always comes first, so many experts are working on formulations of additives to make them even better. This is the company's mission: to remain the reliable and best sports nutrition manufacturer in the world. The company always remains true to its principle: "To get the best, you need to invest the best."
