OnDose vs NutriStack

Know what you're taking. OnDose organises your supplements by timing and absorption, flags interactions from published research, and tracks what you take each day. Not medical advice. Just clarity. — SEE HOW THEY INTERACT Add a supplement and instantly see what competes, what combines well, and what to separate. Every interaction in your stack is checked against published research. Severity levels from Info to Avoid, each with a cited source. Zinc blocks iron. Calcium competes with magnesium. Your morning stack might be cancelling itself out. OnDose catches it. — GET YOUR TIMING RIGHT Supplements are grouped into timing windows based on absorption science. Iron on an empty stomach, magnesium in the evening, competing minerals separated by two hours. OnDose builds your daily schedule so you don't have to think about it. — DAILY CHECK-IN Your daily schedule shows what to take and when. Check off each supplement as you go, build a streak, and look back at any day to see exactly what you took. Push notifications at each timing window keep you on track. — SCAN. DON'T TYPE. Point your camera at a product's UPC barcode. OnDose checks against 37,000+ supplements from DSLD, Open Food Facts, and major brands. Name, dose, and ingredients fill in automatically. Not in the database? Photograph the Supplement Facts label. Ingredients, doses, and serving size are extracted automatically. — ORGANISE YOUR STACK Add supplements, set doses and timing, and keep your full routine in one place. — YOUR DATA, ALWAYS Export your full supplement history, check-ins, and stack configuration as JSON or CSV. No lock-in. If you leave, your data leaves with you. — WHAT'S INSIDE • 350+ supplement compounds covered • 100+ interactions checked with cited sources • 37,000+ barcodes indexed • Timing recommendations based on absorption science • Daily check-ins with streak tracking • Push notifications for each timing window • Barcode scanning and label photo OCR • Full data export (JSON/CSV) — ABOUT THE DATA Interaction data is sourced from NIH Office of Dietary Supplements, EFSA, and peer-reviewed journals.

NutriStack is a supplement tracker and interaction checker built on real evidence. Add your supplements and medications and instantly see where they interact, where they work in synergy, and how strong the research behind each one really is. It is the safety check most supplement apps leave out. CHECK FOR INTERACTIONS See potential interactions between your supplements and your medications, with clear explanations and what to do about them. This is NutriStack's core. Most apps log your pills; few tell you whether they belong together. SCAN AND GRADE (NEW) Scan a large new database of supplements and get an instant grade based on quality and the evidence behind each product, so you can tell a genuinely good formula from good marketing. ASK THE AI (NEW) A built-in AI that answers your questions from NutriStack's own research and interaction database, not the open internet. Ask about timing, combinations, or what the evidence says and get an answer grounded in the app's own data. BACKED BY RESEARCH Thousands of supplements and studies with real citations and evidence grades, so every claim is something you can check for yourself. This update adds more studies and broader interaction coverage. TRACK WHAT MATTERS Log doses and timing, keep your daily routine on track, and see your whole stack at a glance with a stack quality score.
