What is Melatonin?
Melatonin is a hormone naturally produced by the pineal gland in the brain, primarily as a response to darkness. It plays a crucial role in regulating sleep-wake cycles, commonly known as circadian rhythms. Synthetic melatonin can be manufactured and used in dietary supplements.
People often use melatonin supplements to help with sleep problems, such as insomnia or jet lag. The health evidence is mixed; some studies suggest it can effectively aid sleep for certain conditions, while others show limited or no benefit for chronic sleep issues.
When you see melatonin on a label, it's important to note that the dosage and the individual's sensitivity can influence its effectiveness and any potential side effects.
