Three ages, one clock
How old are you, really? Juvenai combines your blood and your wearable to show how fast you are aging and why.
- From biomarkersPhenoAge, from 9 markers in your blood test. What has built up over time.
- From your wearableSteps, VO2max, HRV and sleep over the last 28 days. What happens every day.
- CombinedBoth together, weighted by how recent and complete your data is.
Biomarkers: PhenoAge (Levine et al., Aging 2018). Wearable: 4-domain index calibrated against PhenoAge (Pyrkov 2021, Shim and Onnela 2025).

How it works
From blood to a plan, in three steps
Every test, every night of sleep and every conversation adds to the same story, so care starts before symptoms do.
Blood draw
At a partner lab or at home. Results in 3 to 5 business days.
Results with context
A doctor reviews them and the app turns them into your biological age and a weekly plan.

Juvenai AssistantReads your app data
OnlineAm I aging well?
Yes. You are 45 by the calendar and 42.5 biologically, so you age 0.89 years for every year.
What would help most: your triglycerides are 168 mg/dL. Cutting sugar and ultra-processed food and adding exercise usually moves them in 8 to 12 weeks.
I slept badly this week. Does it show?
Yes: your HRV dropped 14% and your wearable age rose 0.4 years. Get back to 7 hours and it should settle within a week.

FAQ
Common questions
Do I need the band or a wearable?
No. Every plan includes a year of the app and web app, where you see your results, the doctor’s note and your plan. If you connect a wearable, your biological age adds the wearable and combined versions.
How are the three ages different?
The biomarker age comes from your blood test (PhenoAge) and reflects what has built up. The wearable age comes from your steps, VO2max, HRV and sleep over recent weeks. The combined age blends both by how recent and complete your data is.
Which plan should I choose?
For your first test, Integral: it covers what changes decisions most without the full hormone panel. Essential works for repeat tests and trends; Complete if you want the full picture.
What does each plan include?
The doctor’s order, the blood draw at a partner lab, analysis of every biomarker in the plan, a doctor’s review, the action plan and a year of the app and web app. No extra charges at the lab.
How long do results take?
3 to 5 business days from the draw. We let you know in the app when the doctor finishes the review.
Is it covered by Fonasa or my isapre?
Not yet: it is paid privately. We give you the receipt and test details in case your supplementary insurance reimburses part of it.
Who sees my results?
You and the reviewing doctor. When you use the assistant, your data travels pseudonymized: your name, ID number, email, phone and address never leave.
