SuppLab: Supplement Tracker

SuppLab is a supplement tracker for people who take a few things every day and want to know two things: what it all costs, and whether any of it is making a difference. TRACK YOUR STACK • Log every supplement and vitamin you take, with timing and on/off cycles • Daily reminders that fit your routine — morning or evening • Monthly and yearly cost, so you always know what your stack costs • Stack check: flags pairs that shouldn't be taken together (zinc + iron, and more) • Label scan: point the camera at a label to add what's in it A LIBRARY YOU CAN CHECK • 111 supplements, from magnesium and creatine to ashwagandha and omega-3 • Evidence graded strong, moderate or limited — every reviewed entry links its PubMed sources • What to expect and when, cautions, and drug interactions COMPARE TAKE-DAYS WITH SKIP-DAYS • Pick one supplement and one primary measure: sleep, HRV, resting heart rate, energy, focus or mood • SuppLab builds a randomized 14–28 day take/skip schedule and reminds you each day • Sleep, HRV and resting heart rate come from Apple Health; energy, focus and mood take a 10-second check-in • At the end you see the average difference between take-days and skip-days with its uncertainty — or a plain "not enough data" when there isn't enough This is a personal comparison, not a clinical trial. It can't prove cause and effect, and it is not medical advice. LONG-TERM VIEW • Your last 28 days of Health data compared with the baseline you started from • Export everything as CSV to share with your doctor PRIVATE BY DESIGN • No account, no sign-up, no server. Everything stays on your iPhone. FREE AND PREMIUM The library, label scan, stack, reminders and cost tracking are free. Take/skip comparisons, result reports and the long-term view are part of SuppLab Premium (annual with a free trial, or weekly). SuppLab is an educational tool for healthy adults. Consult a healthcare professional before starting or stopping any supplement.
