INDEX ZEROTM
A precise baseline of how your biology compares with your chronological age — and the starting point for measuring how it changes over time.
An estimate of the age your body is living at, derived from your biomarker profile and interpreted against your chronological age.
How fast your biological-age curve is moving, and in which direction.
Your measured NAD⁺ level, interpreted with the laboratory’s available reference data.
Secure your baseline assessment.
Concierge blood collection at your convenience.
A physician-interpreted baseline with clear next steps.
*At Index Zero, Pace of Aging represents an initial estimate based on your current biological-age profile. A true longitudinal pace is established by comparing biological age across two or more points in time. Biological age is an estimate based on the biomarkers and methodology used and is not a diagnosis. NAD⁺ reference ranges depend on the laboratory and assay.
