Why I Built Function — and Why Function Day Matters
Hi Everyone,
I've spent the last 30 years chasing one question: why do people get sick when they don't have to?
The answer comes back the same almost every time. They didn't know. They felt fine until they didn't. And by the time something finally showed up, the easier window to do something about it had already closed.
That's what drove everything I built in functional medicine. Not waiting for disease and treating it. Seeing the signals sooner. Reaching people earlier, before small problems become serious ones.
So I built something to change the timeline. Function is an AI-powered health platform that gives you access to 160+ lab tests — biomarkers that show what's actually happening inside your body, reviewed by clinicians who help you understand what to do with the results. Most people have never had access to this. It either wasn't available to them, or it would have cost tens of thousands of dollars to piece together on their own. Function changes that.
It's also why, when I came across SuppCo, I signed on as an Advisor and investor. If Function tells you what's happening inside your body, SuppCo makes sure what you're putting into it is actually worth taking. Know your inputs, know your biology. I've always believed those two things belong together — that's the full picture.
This week is Function Day, our one moment each year to make that access even easier. Once a year, we open up our best offer of the year, because I believe the barrier to understanding your own health should be as low as it can possibly be.
Here's what's on the table.
New to Function?

A $200 credit toward an Annual MRI, bringing your price to $799
Already a Function member?
Keep building. Through July 1, you have:

This offer ends July 1, and I'd hate for you to miss it.
Function gives you the data to stay ahead. SuppCo gives you the confidence that what you're putting in your body is worth taking. Together, they're the foundation everyone deserves.
Take advantage of this. Your future self will thank you.
Wishing you health and happiness,
Mark Hyman, MD
