Potential Side Effects

Melatonin supplements are recognized as generally safe for most individuals, and side effects are uncommon. Potential side effects for adults include headaches, dizziness, drowsiness, and nausea.

Some adults have reported depression, irritability, and stomach pain while taking melatonin.
