The best nutrition is the mission of Rule One

Creating and delivering the best protein powders and nutritional supplements in the world; that’s our mission. It’s an ongoing quest. Being good is never good enough. We wake up every morning thinking about ways to improve our products and processes. To be the best, you never stop striving.

A new story - four decades in the making

We are athletes, bodybuilders, crossfitters & powerlifters. Guys who've lifted a few million lbs & downed a few thousand scoops of protein. We're also supplement pros who've done this before. Guys who know the difference between the good stuff & the over-hyped wannabes. For those who are serious about getting the best out of lifting are obsessed with 1 thing. Protein. And a quick comparison of top-selling brands shows r1 protein delivers more of what we all take protein for...Protein!

With state-of-the-art production facility in Aurora, Illinois. Rule 1 is one of the few sports nutrition companies to manufacture in every product category. From the very beginning, rule 1 has always taken a hands-on approach to maintaining the very highest standards of quality.

State-of-the-art facilitation

Rule 1 proteins products are produced in our state-of-the-art facility, nutrivo. This impressive manufacturing site is gmp certified and utilizes the latest measuring, blending, conveyance, and packaging technologies to help facilitate our mission of building the finest quality nutritional powders that money can buy.

The source of our strength

When sourcing the raw materials that go into rule 1 proteins products, we focus on purity, potency, and a research-backed reputation over price. Only ingredients that pass rule 1 proteins’ stringent standards for safety, quality, and efficacy are ever considered. We also choose strong, well-respected branded ingredients like carnosyn®, nitrosigine®, infinergy™, hydromax™, and teacrine® to create formulas that deliver the results that our customers expect.
