The problem

A label tells you what's in the bottle. Not what happens with your other bottles.

Googling “X with Y” usually gives you three different answers.

Most products are checked one at a time. That’s not how people take them.

Sometimes it’s not the ingredient. It’s the timing.

4,100+

ER visits per day · U.S.

Every day, thousands of people visit the ER from adverse drug events, including known drug interactions.

Information is your first line of defense.

Source: CDC ↗·Not all interactions require emergency care

Because interactions happen between products — not in isolation.

The ladder

Not just warnings.
Reasoning.

Five severity tiers, each with the mechanism, evidence level, and study basis behind the verdict. Tap a tier below.

Monitor

Magnesium + Levothyroxine

Minor absorption shift

Mechanism

Magnesium may reduce levothyroxine absorption when taken too closely together.

Recommendation

Separate by at least 4 hours.

Evidence level

Moderate

Studies

2 pharmacokinetic studies

When evidence is incomplete, we say so directly.

Beyond interactions

Interactions are just the start.

PharmaGuide reads your full stack — not just for conflicts, but for what your medications quietly take away, what's hidden in the proprietary blend, where your nutrients are accumulating, and what got recalled while you weren't looking.
