There is some scientific evidence that melatonin might improve alertness in people with jet lag. But it doesn't seem to be as useful for other jet lag symptoms such as daytime sleepiness. Melatonin might also be helpful for insomnia for some people.
There is also some evidence that melatonin might improve the effectiveness of cancer drugs used to fight tumors in the breast, lung, kidney, liver, pancreas, stomach and colon. But it should only be used for this purpose with the help of a healthcare professional.
Melatonin might also reduce pain in people with a certain kind of headache called a "cluster headache."
There is some evidence that a melatonin cream may help decrease sunburn when used before going into the sun.
A lot of people try melatonin to help adjust their sleeping schedule when they do shift work, but melatonin does not seem to work for this use.
There isn't enough information to know if melatonin is effective for the other conditions people use it for including: ringing in the ears, osteoporosis, epilepsy, birth control, aging, and others.
