Summary

Active substance

Melatonin

What this could lead to

If it works, this could point toward a simple, low-cost add-on treatment to help stabilize mood in bipolar disorder.

What could go wrong

This is a mid-stage trial with 200 participants, so results may not apply to everyone. Melatonin may not improve mood stability more than a placebo.
