A wellness company built on proof, not promises
RY21 LLC creates premium dietary supplements for people who read the label before they buy.
Our story
RY21 LLC began with a frustration shared by our founders: the supplement aisle rewards clever packaging far more often than it rewards good formulation. Labels hid real doses behind proprietary blends, cheap nutrient forms stood in for bioavailable ones, and third-party testing was treated as optional.
We started RY21 to build the opposite kind of company — one where a pharmacist, a dietitian and an analytical chemist all sign off before a formula ships. Every product we make is designed for human daily wellness, produced in cGMP-certified U.S. facilities, and verified lot by lot by independent laboratories.
Today RY21 serves customers in all fifty states, and our standard hasn't moved: if we wouldn't take it every morning ourselves, we don't sell it.

Our mission
To make premium, evidence-based nutrition simple enough that anyone can build a daily routine they understand and trust — with complete visibility into what they're taking and why.
Our vision
A wellness market where full-label transparency and independent testing are the baseline expectation, not a premium feature — and where RY21 is the standard other brands are measured against.
Core values
Radical transparency
Full-dose labels, published testing, and no proprietary blends. If it's in the bottle, it's on the label.
Evidence first
We formulate from peer-reviewed human research, not marketing trends.
Clean by default
No artificial dyes, no unnecessary fillers, and traceable raw materials.
Customer obsession
Real humans answer every email, usually within one business hour.
Quality without compromise
cGMP manufacturing and independent lot testing are non-negotiable.
Built for people
RY21 formulates exclusively for human wellness — never for animals.
Our quality commitment
Every RY21 lot passes identity, potency, heavy metal, microbial and allergen testing at an ISO-accredited independent laboratory before release. Certificates of analysis are available for any batch — just email support@ry21llc.com with the lot number printed on your bottle.
Customer focus
Our support team is U.S.-based and answers every message personally. If a formula isn't right for you within 60 days, we refund it — opened bottles included, no return shipping required.
