What does natural melatonin do in the body?
Your body has its own internal clock that controls your natural cycle of sleeping and waking hours. In part, your body clock controls how much melatonin your body makes. Normally, melatonin levels begin to rise in the mid- to late evening, remain high for most of the night, and then drop in the early morning hours.
Light affects how much melatonin your body produces. During the shorter days of the winter months, your body may produce melatonin either earlier or later in the day than usual.
Why is melatonin used as a dietary supplement?
Melatonin supplement are sometimes used to treat jet lag or sleep problems due to shift work.
