EpiRegen transforms epigenetic clock concepts into a clear, interactive educational calculator: by allowing users to input baseline epigenetic age, intervention type, effect size and duration, the app produces model-based estimates of potential biological-age change and an informational likelihood score, and offers conservative, non-prescriptive suggestions for multi-modal approaches — all presented with a transparent methodology and a prominent disclaimer that the tool is for informational purposes only, not a substitute for professional medical evaluation or regulatory-approved therapies.
