The Problem

You shouldn't need a pharmacy degree to take supplements safely.

Berberine with metformin. St. John's Wort with your antidepressant. Ginkgo with blood thinners. Some combinations are dangerous. And right now, there's no easy way to check.

Confusing

Google results

You searched "is ashwagandha safe with Zoloft" and got 10 conflicting answers. Reddit says yes. A blog says maybe. A PubMed abstract says something you can't understand.

15 min

average doctor visit

Your doctor has 15 minutes. Barely enough to cover your meds, let alone review every supplement you take. Most herb-drug interactions never come up.

< 30%

tell their doctor about supplements

Most people never mention herbs or vitamins to their doctor. That means risky combinations go unchecked until something feels wrong.

86%

take supplements + Rx meds together

Nearly 9 in 10 supplement users also take prescription medications. Most have never checked if their combination is safe.
