Built by runners. For everyone.
Clarion started on a track — and a problem millions share: your labs read “normal” when your body clearly isn't.
It started on a track.
Junior year, I was chasing a state cross-country title — then in three months my mile fell off a cliff. I burned hundreds of dollars on supplements that did nothing.
My labs said “normal.” My body said otherwise.
The real answer was in my own bloodwork the whole time: iron the standard range called “normal,” but dangerously low for a runner. No one caught it — not even my doctor.
Now I work in a running performance lab, and I've watched too many talented athletes lose their best years to deficiencies that should've been easy fixes — because standard ranges are built for the general public, not for people pushing their bodies.
Clarion closes that gap. Personalized ranges — built from published clinical references, then adjusted within evidence-based bounds — that turn your bloodwork into clear actions — what to fix, what to take, and what to stop wasting money on. Built by runners, for runners, and for everyone who wants that precision.
What we believe.
Clarity over jargon
Your results should read in plain language. If you need a dictionary to understand your own body, something's broken.
Personal, not average
A textbook range is built for a population, not a person. Yours should reflect your age, sex, training, and goals.
Honest about money
We'll tell you what your labs actually support — and what to stop buying. We'd rather earn trust than sell you more.
