How it works in your protocol

Most supplements are a guess. Agen earns every capsule from your own data — the measure → analyze → act loop.

Step 1

Measure

The Band tracks your HRV, sleep and resting heart rate; the app reads your stress load across the day.

Step 2

Analyze

When recovery dips and stress climbs, Agen flags adaptogenic support — and scores the evidence behind it.

Step 3

Act

It enters your daily protocol at the right dose, dispensed by the Robot each evening.

Underwhelmed — a couple of letdowns

Couple of issues stopped me enjoying it. Unfortunately the seal on my bottle wasn't intact on arrival.

We really appreciate you flagging this. We'd love to help — drop us a line at support@agen.com and we'll sort a replacement or refund.
