Navigate the supplement and health-device jungle.
Supplements and health technologies range from well-established interventions to expensive hype. Stack helps you understand what may be relevant to you, how strong the evidence is — and what may not be worth your money.
Explore StackDeveloped and operated by Vila Health.
Transparent evidence grades
Every item gets an A/B/C grade so you know exactly how strong the evidence is.
Foundation → targeted → advanced
Your stack is prioritised in a clear order, so you build on solid ground first.
What we leave out — and why
Stack also tells you what has deliberately been left out, and the reasoning behind it.
A — Consistent human RCTs
B — Promising or mixed human evidence
C — Early, mechanistic or observational
Screened for interactions
Your screening checks for possible interactions with medication and contraindications before anything is suggested.
Our principles
- Evidence-graded
- Transparent
- No paid placements
Talk to your doctor before combining supplements with medication, and never change your medication based on this tool.
