You chose each supplement for a reason. Know what’s worth keeping, what’s worth changing, and why. Supplement AI synthesizes what human research reveals about what works for whom, then applies that understanding to your products, doses, goals, and circumstances. See how much each supplement contributes to your goals, where products overlap, and where support could improve. Your Goal Support score is based on the opportunities available to you—not an ideal regimen that ignores your circumstances or restrictions. A better stack doesn’t simply mean taking more. Find the changes that matter most for your stack, whether that means adding a supplement, adjusting a dose, or replacing a product. See what each change would contribute and why it fits, with dose, quality, overlap, relevant risks, and value considered together. You decide what to apply. Human studies differ in who they include, what they measure, and what they find. Supplement AI carries those distinctions into your assessment alongside the context you provide, including your age, sex, diet, medications, conditions, and allergies. Explore the research behind your recommendations, its limitations, and the risks and interactions relevant to your stack. Start with what you already take. Add products through search, barcode scanning, or label photos. Plan doses, set reminders, and log what you take. Run a new analysis when your products, priorities, or circumstances change. Supplement AI is built around your decisions. We don’t sell supplements, run supplement ads, accept supplement sponsorships, or earn affiliate commissions. Start free Your first analysis and optimizations are free, with another analysis available every two weeks. An optional Plus subscription includes 16 analyses per month, full access to your analysis history and past optimizations, and budget optimizations. An account is required. Subscription pricing and terms are shown in the app before purchase. Supplement AI provides evidence-based decision support, not medical advice, diagnosis, treatment, or a guarantee of safety. Scores summarize research and personal context; they do not measure your health or predict percentage improvements. Consult a qualified healthcare professional before making changes to supplements or medications.
