Were you looking for information about Melatonin? Melatonine is a common misspelling of melatonin.
Melatonin is a naturally occurring hormone that is often used in the form of a supplement to help treat various sleeping disorders. When used in supplement form, the product is also claimed to be helpful for several other uses, such as preventing migraine headaches, treating fibromyalgia, and treating cancer (when combined with standard cancer treatment). Although it is a "natural" product, melatonin may cause side effects, such as dizziness, nausea, and depression.
