Frequently Asked Questions

Can I trust this information?

Every ingredient page shows an evidence grade, last-reviewed date, and references, reviewed by an internal-medicine specialist. Still, consult a professional before deciding to take anything.

If it's "strong evidence," must I take it?

No. "Strong" usually means benefit when correcting a deficiency. If you are not low, benefit may be limited.

How does the recommendation work?

You enter health goals and medications; a rule-based engine suggests related ingredients. It is not a diagnosis and cannot fully reflect your situation.

Where is my data stored?

Your saved list and quiz answers stay on your device and are not sent to any server.

Is US product info included?

Yes. Each ingredient page compares the Korea and US markets.
