What's On the Label Is In the Tub.
Our Story
Rule 1 exists for one type of customer: the athlete who flips every bottle around before putting it in their cart. No proprietary blends means no mystery dosages hiding behind a blend name. Their R1 Whey, R1 Creatine Anhydrous, R1 Pre-Lift, and R1 Clean Gainer all list exact ingredients at exact amounts — nothing invented, nothing concealed. The brand was founded by former Optimum Nutrition executives Mike and Tony Costello, who built their reputations on the same clean-label philosophy that Rule 1 was created to deliver. The military and first responder community latched onto this brand early because those communities don't have time for marketing language on a label. If you want to see what's actually in your supplements instead of trusting the proprietary blend listing, Rule 1 is the brand that shows you exactly what you're paying for.
Why Rule 1 Stands Out
Est. 2014 | Former Optimum Nutrition Founders
Built by the founders of Optimum Nutrition — decades of formulation experience channeled into a clean-label-only brand.
No Proprietary Blends. Period.
R1 Whey, R1 Creatine Anhydrous, R1 Pre-Lift, R1 Clean Gainer — every label lists exact ingredients at exact dosages. What you see is what you get.
Military & First Responder Trusted
The communities that can't afford to guess what's in their supplements were early adopters. That loyalty is the most valuable word-of-mouth in the industry.
Genuine, Sealed Stock
Every Rule 1 product we ship is genuine, bought in the U.S. through established supply channels, and sealed in its original packaging.
Clean Gainer, Clean Protein, Clean Pre
R1 Clean Gainer for mass, R1 Whey for recovery, R1 Pre-Lift for training. A focused, transparent line your customers can stack without a label-reading headache.
The Label-Reader's Brand
Athletes who check supplement facts before buying are the most loyal customers. Rule 1 gives them nothing to argue with.
