Know Thyself.
Prove It.

Every supplement you take, every blood panel you run, every metric your wearable tracks — Temet connects it all and tells you what’s actually working for your body.

Early access coming soon. No spam, just a heads up when we’re ready.

You take 12 supplements. You’ve done three blood panels. You wear two devices. But you still can’t answer the most basic question: Is any of it working?

The Intervention Engine

Finally answer: did this
supplement
actually do anything?

Say you start taking Magnesium Glycinate. Temet watches your HRV, sleep quality, and resting heart rate. After 21 days, it tells you exactly what changed — and how confident it is that the supplement caused it.

Other trackers show you dashboards. Temet shows you answers.

“Stopping the cold plunge protocol will decrease morning HRV, confirming its benefit to autonomic regulation.”
The Cold Plunge protocol showed a statistically significant effect on HRV (+8.3%, p=0.02). Morning HRV readings were consistently higher on plunge days. Resting HR and subjective energy showed no meaningful change. Recommendation: resume if HRV optimization is a priority.
