Science you can
swallow.
Supplements formulated the way physicians formulate prescriptions: evidence-led, active-form, third-party tested, and printed with the full panel — no proprietary blends.
“Most supplements fail the same basic test: they use the cheapest form of an active because it's legal to call it the same name. We don't.”
— Dr. Lena Chen, MD · Co-founder

Manufactured in Boulder, CO
Built by physicians.
Tested by everyone else.
Our founders are Dr. Lena Chen, MD (internal medicine, Stanford) and Dr. Marcus Thorne, MD (endocrinology, Columbia). They spent fifteen years prescribing supplements to patients and being disappointed by the gap between research and shelf product.
Every batch we manufacture is tested by an independent ISO/IEC 17025-accredited lab before release. Every Certificate of Analysis is published. Every active form is the one cited in the original research.
The Clinic Notes
Monthly research,
not marketing.
One email a month from our science team. Recent studies we are reading, ingredients we are reconsidering, and the occasional recall warning from the FDA we think you should know about.
