The duration of action of melatonin gummies can vary depending on the specific product and the individual's metabolism. In general, melatonin is metabolized quickly by the body and has a half-life of approximately 1-2 hours. This means that it takes about 1-2 hours for the body to metabolize and eliminate half of the dose of melatonin.
The effects of melatonin gummies can last for several hours, but the exact duration of action can vary from person to person. Some people may find that the effects of melatonin gummies last for 4-6 hours, while others may find that the effects last for longer or shorter periods of time.
