A drug is only as good as its crystals.

The way a molecule arranges itself as it solidifies determines how well it dissolves, how stable it is on a shelf, and how much of it the body can absorb.

Get the structure wrong, and a medicine that works in theory fails in practice.

Gravity interferes with that process.

As a crystal forms in solution, denser material sinks and convection currents stir the liquid, both of which introduce defects.
