Melatonin

Melatonin is a naturally occurring hormone primarily produced by the pineal gland in the brain that acts as our body’s biological “dark signal.” Its production is dictated by environmental light. Levels typically rise after sunset, peak in the middle of the night to signal time to sleep, and drop significantly in the morning to promote wakefulness. While it’s not a traditional sleeping pill that’s sedating, it helps regulate circadian rhythm — the internal 24-hour clock that manages sleep-wake cycles. Beyond its role in sleep, melatonin also functions as a potent antioxidant, assists in managing core body temperature and blood pressure, and may influence immune and reproductive system health. It can help soften jet lag, shorten the time it takes to fall asleep, and assist with circadian disorders (particularly for blind people and as an adjunct treatment for unipolar and bipolar depression).
