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. WHO IT IS FOR Anyone taking more than a couple of supplements, from beginners who just want to stay safe to enthusiasts optimizing a complex stack.
