We built Radiant Life™ so you can build your supplement regimen on your own measured data.
Not on a label. Not on a recommendation. On what your biology actually shows.
FOUNDER’S NOTE
I have taken supplements for most of my adult life. I bought them because someone told me they worked, or because a study suggested they might. I took them because the alternative was doing nothing. And for most of that time, I had no way to know whether any of them were doing anything at all — no baseline, no measurement, no way to attribute change to cause.
Our Foundation Input supplement was different. It was the first supplement where the effect was unmistakable — dry eye vanished, energy returned, cognition sharpened. And yet I still could not point to a record and say: here is where I started, here is what changed, here is what I was taking when it changed.
That gap — between taking something and knowing something — is what Radiant Life™ is built to close. Not as a brand argument. As a system that lets you build your supplement regimen on your own measured data.
— Terry, Founder, HealthspanX
A system designed for clarity, not belief.
The supplement industry operates in reverse. Products are designed first, marketed second, and consumed by people who have no way to know whether anything is happening. The order is wrong — and it is wrong in a way that serves the brand, not the participant.
Radiant Life™ was built to correct that order. The Assessment comes before the product. The baseline comes before the window. The data comes before the recommendation. Every structure in the system is built to make the question ‘is this doing anything?’ answerable — with documentation, not belief.
How the system operates.
We do not ask anyone to trust that a supplement is working. We document whether it is.
A structured baseline, standardized conditions, and a defined measurement window are the only way to know.
Your data is the only input that should determine your regimen.
We do not predict, optimize, or guarantee. We record what happens under the conditions we can control — and let your documented data determine what your supplement program becomes.
The 100-day window is not a marketing choice.
It is the length of time where biological signal separates from noise. Shorter intervals bring in more variables. Longer intervals dilute what you can attribute to the input.
A documented record of your own biology — and a supplement regimen built from it.
Most people who complete the RL100 window come out with something they have never had before: a documented record of their own biology across twelve domains, measured under the same standardized conditions at three points across 100 days.
That record is not an interpretation. It does not tell you whether something worked. It tells you what was measured, when it was measured, and what the Foundation Input supplement conditions were throughout. What the data means is yours to interpret — with your clinician, or on your own.
Graduates who choose to continue gain access to the Graduate Decision Page. Support and Path supplement products are structured around what their measurements showed — domain by domain. If the sleep domain measured low, there is a Path supplement addressed to that biologically. If cellular energy showed a documented pattern, there is a Support supplement for that. The decisions are not generic — they are structured around the specific documented picture of one person’s biology.
Over multiple windows, each completed window adds a layer of documented data. Each subsequent supplement decision is made against a richer, more precise picture — building, window by window, a supplement program structured entirely around the documented biology of one person.
The team.
Radiant Life™ was built by a team that includes medical doctors and researchers. Formulation review is conducted independently. Regulatory counsel is external. Contract manufacturing operates under cGMP standards. A dedicated engineering and data team supports the measurement system.
The twelve-domain assessment framework, the scoring architecture, and the 100-day measurement protocol reflect input from people who work at the intersection of clinical research and biological measurement.

Contact.
For questions about the system, participation, or your protocol, contact participant support at support@healthspanx.com. We respond during business hours — response times vary. There is no live chat and no phone line. This is deliberate: we work at the pace of careful response, not reactive response.
Who this is not for.
If you want a supplement that produces a visible effect in a week, this is not built for you. If you want personalized stacks, biohacking protocols, or a product that promises outcomes before you take it, this is not built for you either. Radiant Life™ is for adults aged twenty-five and above who want their supplement decisions grounded in documented biological data — built progressively from their own measurements, not from a brand’s generic recommendation.
Begin the Assessment.
The Assessment is free. It takes five minutes. It establishes your biological baseline across twelve domains — the first piece of the data your regimen will be built on.
