You might take a few daily supplements like vitamins, magnesium, or something for sleep, trusting the labels and your routine. But recalls can slip by unnoticed or ingredients can overlap without warning.
Most users manage multiple OTC products with scattered reminders and complex safety notices, often unaware of risks until it’s too late.

You might take a few daily supplements like vitamins, magnesium, or something for sleep, trusting the labels and your routine. But recalls can slip by unnoticed or ingredients can overlap without warning.
Many people manage multiple OTC products without reliable safety information, often unaware of interactions or recalls until it’s too late.
As supplement use increases, safety has become a personal task rather than a guided process.
Most tools focus on reminders, not context, making alerts either too frequent or too late.
This opened an opportunity to create a system that feels adaptive, human, and trustworthy, delivering safety information at the right time, in plain language, with no extra effort.
As supplement use grows worldwide, safety has become a personal responsibility rather than a guided process. Existing tools focus on tracking or reminders but fail to adapt to user context, making safety alerts either too frequent or too late.
This gap created an opportunity to design a system that feels adaptive, human, and trustworthy, where safety information reaches people at the right time, in plain language, and without extra effort.

Through surveys and interviews, I found that over 60% of users take three or more OTC products at once,
yet nearly 70% rarely notice recall or interaction alerts until it’s too late.

To make safety guidance approachable, I focused on clarity, timing, and empathy.
The goal was to replace static alerts with adaptive reminders that fit naturally into users’ daily patterns.
The app centers on supplement registration, context-aware notifications, and a conversational chatbot, ensuring safety information arrives at the right moment and in plain language.
The user flows focus on two pillars, context-aware nudges and conversational guidance, making safety feel timely, intuitive, and natural.
