Melatonin, a hormone naturally produced by the pineal gland in the brain, plays a crucial role in regulating sleep-wake cycles. It is also available as a dietary supplement and is commonly used to help with sleep-related issues such as insomnia or jet lag. How long does melatonin last? If you're considering taking melatonin or have already started using it, you may be wondering about its duration of action and how long it lasts in your system.

The duration of melatonin's effects can vary depending on several factors, including the individual's metabolism, dosage, and form of administration. Typically, the effects of melatonin start within 30 minutes to an hour after ingestion and can last for a duration of 4 to 8 hours. However, it's important to note that these are general estimates, and individual experiences may vary.

The form of melatonin you take can also affect its duration of action. Immediate-release formulations are designed to be released quickly into the body, providing a rapid onset of action. On the other hand, extended-release formulations are designed to release melatonin gradually over an extended period, allowing for a more prolonged duration of action.
