About Ultimate Longevity Bible

Ultimate Longevity Bible is a free, open encyclopedia of longevity science. It summarises the published literature on the biology of aging — the hallmarks, the interventions being studied in humans and animal models, the biomarkers used to track biological age, and the researchers shaping the field.

Editorial stance

We do not sell supplements, run a clinic, or accept sponsorship from products we describe. Pages are written to a non-specialist reader and link to primary literature where possible.

What this site is not

This is not a clinic, a treatment service, or a source of personal medical advice. The interventions described — including pharmaceuticals like rapamycin and metformin, supplements like NAD+ precursors, and behaviours like prolonged fasting — carry real risks and only make sense in the context of an individual's medical history. Discuss anything you read here with a qualified clinician.
