Wellness disclaimer
BioAge is an educational wellness estimate. It is not medical advice, not a diagnosis, not a prognosis, and not a medical device. Do not change medication, supplements, or care based on this demo. Discuss labs with a qualified clinician.
What the numbers are
The primary score is a published blood-marker biological age (Levine et al., Aging 2018; Liu et al., PLoS Med 2019 correction) from routine blood chemistry. Training data are US NHANES — transfer to other regions is a footnote, not a new clock. There is no trained ML model in this demo. A later model can replace the formula without renaming the age you see.
Metabolic, liver, kidney, lipid, and immune cards are marker-based guideline-band proxies. They are not proteomic organ ages and are labeled that way on every result.
If some of the nine markers are missing, the app still shows an estimated age with a ± band that widens as more markers are missing, and lists what to add. That band is an honesty range, not a clinical confidence interval. Available system proxies still use only markers you entered.
Labs and sign-in
Manual entry is the source of truth. PDF upload reads a digital text layer when one exists; it is not OCR and will not reliably read scans or photos. Confirm every filled value against the performing lab’s printout.
Social sign-in is optional and only appears for providers you enable in Supabase and list on NEXT_PUBLIC_AUTH_PROVIDERS. Without those environment variables there is no demo Google identity — you can continue without an account, and history stays in this browser. With Supabase + a social provider, identity and saved lab history are stored for that account.
