Hey Product Hunt! 👋 I built Synstax because I was taking 6+ supplements daily and had no idea some of them were actually blocking each other's absorption. After researching the science, I found that common combinations like calcium + iron, or zinc + copper, can significantly reduce effectiveness. But no app actually warned you about this. So I built Synstax with a 5,142-rule conflict database, a dosage safety engine that checks RDI/UL limits, and 337 diet-supplement interaction rules (like how caffeine affects iron absorption). It also has AI-powered label scanning — just point your camera at a supplement bottle and get instant analysis. Everything works offline, no account needed, no ads. Available in 18 languages. Would love to hear your feedback! 🙏
