Many adults experience frequent or occasional sleep disturbance, including difficulty falling asleep, staying asleep, or waking too early. The most popular natural sleep aid is melatonin because it is effective and safe to use.

Melatonin is the body’s own natural sleep hormone, produced in the brain in the pineal gland each evening when darkness falls. It is part of the “biological clock” that produces the circadian rhythm and prepares the body for sleep. But the natural rhythm of this clock can be disrupted, resulting in difficulty sleeping.

Research shows that taking a melatonin supplement 30–90 minutes before bedtime temporarily resets the biological clock, reduces the time it takes to fall asleep, improves sleep quality, increases total sleep time in people with an altered sleep schedule (e.g., shift work or jet lag), and reduces daytime fatigue associated with jet lag. Unlike pharmaceutical sleeping pills, which can disrupt the critical REM stage of sleep, melatonin supports REM sleep.

Safe and effective Natural Factors Melatonin is made from non-animal sources. The sublingual tablets ensure fast, consistent absorption and are available in four strengths to provide the right dose for your needs. Sleep is very important. If you have a serious sleep disorder, consult a health care practitioner.
