Stack — what to take, from your data

How it works

Three steps, no guessing.

01 · CONNECT

It starts from you

One tap for Whoop, Oura, or Apple Health — official APIs only. On Garmin, Fitbit, Polar or Suunto? They sync through Apple Health too. Then add what a wearable can't see:

Bloodwork uploads — a PDF is enough
DEXA and InBody scans
Your goals: sleep, recovery, strength, focus

02 · REVIEW

A short list that shows its working

Five bottles, not fifty. Every line carries its dose, its timing, and its evidence level — with the trials behind it one tap away. When the science is thin, the app says so, in orange, before you spend a dollar:

"Proven in many trials" vs "Early evidence, low risk" — labeled honestly
Interactions and cautions surfaced before you start
Already take something? Deselect it, the list adapts

Your Perfect Stack with evidence and cautions

03 · ORDER

One payment, delivered

No retailer accounts, no five checkouts. One Apple Pay charge — we source real brands, buy the bottles, and ship them to your door. Then the app keeps watching your data to see if anything actually moved.

Real brands: Thorne, Pure Encapsulations, Optimum Nutrition
Transparent pricing — products + 10% sourcing + shipping
Daily check-ins track whether it's working

The engine

200+ papers. Zero hype.

Supplement marketing shouts; Stack cites. We indexed the peer-reviewed literature — what was tested, on whom, at what dose, with what result — and show you exactly why something is on your list. Your bloodwork and your wearable decide what applies to you.
