SafeDoser
Closing the gap between frequent supplement use and the lack of professional medical guidance
Every day safety depends on luck.
SafeDoser helps users make data-informed supplement safety decisions instead of relying on habit.
Research showed that 60%+ of users take three or more OTC products, yet nearly 70% rarely notice recall or interaction alerts, leaving safety risks unseen.
SafeDoser reframes the problem around one question: “Is this safe to take right now?”
By integrating real-time FDA recall data into a context-aware, conversational interface, it delivers clear, timely safety guidance while reducing cognitive load.
What’s the problem?
OTC supplement use is increasing, but safety awareness isn’t keeping up.
What’s the solution?
SafeDoser integrates FDA recall data, dosage reminders, and visual guidance into one connected experience.
Discovery & research
Understanding why users miss critical safety alerts
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.
Users described alerts as overwhelming, irrelevant, or hard to understand.
Key challenges
Alerts sound too technical, causing stress or confusion
Users can’t tell when safety information is important
Current tools don’t adapt to personal routines or behaviors
Research revealed three critical gaps that shaped the design direction.
Safety as Guidance
Trust Through Context
Alerts must adapt to when users actually need them.
Recall Risks Go Unseen
User Journey & Personas
Users experience anxiety when they feel uncertain about safety or dosage.
Mapping daily habits revealed how and when trust breaks down during their routines.
User journey map
User routines reveal moments of anxiety and uncertainty, where timely and human guidance can rebuild trust in supplement safety.
“How might we design a supplement safety system that feels adaptive, clear, and human?”
What’s the idea?
screen flow
The screen flow connects alerts, reminders, and confirmations into one continuous guidance loop.
From registration to recall alerts, every step uses clear hierarchy and friendly microcopy to reduce stress and build trust.
Prototype Overview
Interaction Details
Notifications adapt to each user’s context instead of fixed schedules.
This design minimizes alert fatigue and builds trust through relevant, timely communication.
Users can ask questions in plain language, such as “Is this supplement safe with magnesium?”
Micro-interactions transform safety alerts into meaningful dialogue, making health guidance approachable and human.
