What it helps with
How it works in your protocol
Most supplements are a guess. Agen earns every capsule from your own data — the measure → analyze → act loop.
Measure
The Band tracks your HRV, sleep and resting heart rate; the app reads your stress load across the day.
Analyze
When recovery dips and stress climbs, Agen flags adaptogenic support — and scores the evidence behind it.
Act
It enters your daily protocol at the right dose, dispensed by the Robot each evening.
What the science says
Every claim scored by evidence strength — including the ones that aren’t there yet.
Promising early human data; larger trials are still needed.
Early signals only — the honest answer is the evidence isn't conclusive yet. We'll update this the moment it is.
