---

Every explanation you read in LifeFrom is joined to a cited knowledge entry, what a marker is, why it matters, what high and low mean, what to aim for, each with real sources.

## Why not just ask an AI live?

Live answers are slow, inconsistent, and uncited. A reviewed corpus is instant, consistent, and traceable, with the AI adding only the part that’s about you.

[Add the lab results you already have, and LifeFrom reads each marker next to the others it moves with, in plain language, with the sources it used. Free, on the web or in the app.](https://lifefrom.ai/start)
