What it does

Synstax is the only supplement app that goes beyond pill reminders. It detects dangerous interactions between your supplements (5,142 rules), warns when combined doses exceed safe limits (RDI/UL), and tracks how your diet affects absorption (337 diet-supplement rules). Plus AI-powered label scanning and smart scheduling. No account, fully offline, no ads. 18 languages.

Check supplement interactions, food effects, timing gaps, and label ingredients before you take them. Built on 5,142 rules and 1,110 ingredient profiles.

Use the website to answer one combination at a time. Use the Synstax iPhone app to scan your bottles, check covered combinations across your list, build a daily schedule, and track what you take. Every feature is designed to make your supplement routine clearer, easier to time, and easier to review. Places each supplement into a time slot based on absorption needs, food effects, interaction gaps, and your daily routine. The website helps with one pair at a time. The iPhone app checks covered combinations across the active supplements in your list and uses those findings when building your schedule. Photograph the front and Supplement Facts panel.
