Biostacks: Supplement Tracker

• Supplement and medication interactions, from NIH Office of Dietary Supplements fact sheets and PubMed studies, each with a link
• Synergies between supplements, from PubMed meta-analyses
• Research coverage for 18 health goals, from sleep to longevity: what the meta-analyses found and the doses they studied
• Upper limit warnings and RDA coverage for vitamins and minerals, from NIH and USDA reference values, with the harm NIH lists for going over
• Additives checked against FDA GRAS rules and the EU food additive regulation
• Brand records: NSF, USP, Informed Sport, Kölner Liste, NZVT, and Eurofins certifications, Health Canada licences, FDA warning letters, and FDA, UK, and French recall notices
• Nutrient overlaps between products

Experiments

• Daily check-ins on mood, energy, sleep, and focus
• Metrics: weight, sleep, resting heart rate, HRV, steps, or any custom number, with Apple Health sync
• Scan a lab report, blood test, body composition, or aging report from a photo or PDF, read on your phone, never uploaded
• Run an N-of-1 trial: three weeks off and three weeks on, alternating weekly. The result says whether a metric moved, or "no effect" when it did not
• Experiment results appear only after enough logged days

Supplement scanner and vitamin tracker

• Barcode scanner with your camera, for supplements, vitamins, pills, and medicine
• Search NIH DSLD and Open Food Facts, with popular brands available offline
• Enter supplements, medications, doses, and nutrients manually
• Ask Apple Intelligence (iPhone 15 Pro and newer)
• Use your own assistant like Claude, Grok, or Gemini to manage your stack with a copy-and-paste prompt

Supplement schedule, pill and medication reminders:

• Daily, specific weekdays, or on/off cycles like 5 days on, 2 off
• Multiple times of day, from multivitamin to magnesium
• Peptide tracker and peptide calculator: vial size, reconstitution, and draw volume
• Dose reminders, with smart tuning when you keep logging late

Dose log

• One tap per dose, mark a whole stack at once, long-press to skip and keep your streak
• Progress rings, streaks, and dose logging by asking Siri
• Taken, due, and upcoming groups, and a calendar with mood dots
• Search, filter, notes, reorder, and dark mode
• Adherence and Stack Analysis trends over 30, 90, or 365 days, with CSV export
• Monthly cost per supplement and per stack, and running-low refill alerts

On-device AI chat

• Every suggested change appears as a review you accept or reject, with undo

Privacy first

• Works offline with no account
• Your health data stays private, on your device
• Optional backup and sync to your own iCloud
• Snapshots and version history to roll back any change
• Export everything as JSON or PDF, or share a stack as plain text
