For the third year in a row, Function was back as title sponsor of @eudemoniasummit!
As the #1 brand for understanding your health, we led the conversation on-site and made checking your health easier than ever. On-site blood testing. MRI appointments. Expert conversations on stage and at the Function Lounge. Together with our members and partners, we brought our mission of 100 healthy years to life.
To our members who stopped by to share their Function stories, we loved seeing you.
To the new faces who came to ask questions and sign up: thank you.
Time spent in community can add years to your life. We hope it’s 100.
Long live Eudēmonia.

@theproof wants to know how his body responds to the changes he makes. That means testing, taking action, and testing again.
With elevated ApoB and a family history of early heart attacks, he pays close attention to how his levels change over time.
At @EudemoniaSummit, Simon shared what he values about Function: comprehensive testing and guidance that helps him make sense of his results—and what to do next.

We’re back at Eudēmonia for our third year as title sponsor. On the panel: Tiffany Lester, MD, Function’s Women’s Health Medical Director, discussing how to turn your results into informed action.
8 out of 10 Function members take action based on what they learn from their results. But what happens after you make those changes? That’s where tracking trends comes in.
One result shows you where you are today. Tracking your results over time helps you understand what might be working, what deserves more attention, and what to discuss with your doctor.
More data becomes more useful when you have the context to make sense of it.
At @EudemoniaSummit? Find us tomorrow in the Expo at booth #601. Take a right when you walk in and look for our plants! Come hang out and book your lab draw or MRI.

AMA: “Is it perimenopause? What can your labs actually tell you?”
Function’s Women’s Health Medical Director, Dr. Tiffany Lester, is hosting a Reddit AMA on cycle changes, fatigue, sleep, mood, and weight in your late 30s and 40s. What your labs mean, what tracking over time can (and can't) tell you, and whatever else you want to know.

@MrBeast's health challenge came with a surprise for Tré.
Baseline lab tests through Function showed that at 29, his testosterone looked like that of a 90-year-old man. Six months later, follow-up tests showed it rising, along with his wife Sara’s insulin resistance score improving.

@MrBeast health challenge. $250,000 on the line.
And lab tests through Function that showed Sara and Tré numbers they couldn’t ignore.
After six months, they lost almost 160 pounds together. Now they’re back home.
What does it take to make those changes last?

You don’t play at an elite level at 40 by guessing about your health.
@CP3 uses data to understand what his body is telling him.
Function members have access to 160+ lab tests.
