Case study: Melatonin

gwern

I discuss melatonin's effects on sleep & its safety; I segue into the general benefits of sleep and the severely disrupted sleep of the modern Western world, the cost of melatonin use and the benefit (eg. enforcing regular bedtimes), followed by a basic cost-benefit analysis of melatonin concluding that the net profit is large enough to be worth giving it a try barring unusual conditions or very pessimistic safety estimates.

I did link to Wikipedia for a reason; see http://en.wikipedia.org/wiki/Melatonin#Availability_and_safety . But besides AngryParsley's link, there's

Given the unanimous results of safety in the short-term, positive results in long-term child use, the exploitation of a regular physiological process, the long track-record of melatonin use, and the lack of evidence for any long-term harm, I think I'd say the onus is on any doomsayers.

(No doubt there's a witty Eliezerism or post on the topics of negative results and burdens of proof, but offhand I can't think of it.)

It took large scale randomized studies to establish the negative health effects of vitamin supplements/antioxidants and HRT both of which appeared safe in the short term, exploited a regular physiological process and had a long track record of use. I'd want to see a large randomized study of the long term effects of melatonin use in adults to establish the long term effects of melatonin use in adults.

The Wikipedia link you give merely concludes that "evidence suggests that melatonin is safe with short-term use, three months or less". From your o... (read more)
