How long does it take for melatonin 3mg to leave your body?
A doctor has provided 1 answer
Does it last long?: That is a great question. To figure out how long a drug or supplement will stay in your body, one needs to know the half life, which can be found online. The half life of melatonin is around 50 minutes. Drugs are usually eliminated after 4-5 times their half life. So most of the melatonin will be gone in 250 minutes, or 4.16 hours. You can divide 3 by 2 5 times to see how the amount decreases.
