Melatonin 3 mg

Why Take It?

People use melatonin when they have insomnia -- trouble falling asleep and staying asleep. They also take it for other sleep problems. This could include something called delayed sleep phase disorder. If you have that, falling asleep before 2 a.m. is tough. So is getting up in the morning.

Folks may also try it if they have jobs that disrupt typical sleep schedules, a condition called sleep work disorder.

It's used to treat or prevent jet lag, too. That's the tired, run-down feeling some get when they're traveling across time zones.

Doctors are also studying to see if melatonin can help with:

• Alzheimer's disease
• Cancer
• Amyotrophic lateral sclerosis (ALS)
• High nighttime blood pressure
• Sleep problems in children with autism spectrum disorders
