## What is SuppLab?

Does that supplement actually work for you — or are you paying for expensive placebo?
SuppLab turns your supplement routine into a personal science lab: run randomized 21-day self-experiments (N-of-1 trials) and get an evidence-based verdict for YOUR body.
No account, no cloud — all your health data stays on your iPhone.

HOW IT WORKS
1. Pick a supplement and a goal (sleep, recovery, energy…)
2. SuppLab randomly assigns TAKE and SKIP days across 21 days
3. Complete a quick daily check-in while Apple Health tracks your baseline
4. Get a clear decision card: keep it, drop it, or test longer

YOUR STACK, UNDER CONTROL
• One-tap logging for your entire supplement stack
• Adherence percentage — see how consistent you really are
• Yearly waste calculator: what supplements that do nothing cost you per year
• Smart alert when adding a new supplement mid-experiment, so your results stay clean

BUILT ON REAL DATA
• Apple Health baseline: sleep, HRV, resting heart rate, steps
• Subjective daily check-ins combined with objective metrics
• Randomized TAKE/SKIP protocol reduces placebo bias

PRIVATE BY DESIGN
• No account, no sign-up, no backend
• All analysis runs entirely on-device
• Your health data never leaves your phone

Stop guessing. Start testing. Your body, your evidence.
