Melatonin

Widely sold as a sleeping aid; mostly a timing signal, not a sedative

Sleep scientists are lukewarm about melatonin for ordinary insomnia in healthy adults, because it is a hormone that signals biological night rather than a sedative that generates sleep. Matthew Walker allows a much better case for jet lag and circadian shifting. Over-the-counter doses often run many times higher than physiological, and Andrew Huberman argues against routine nightly use on both counts.

    Melatonin he covers as a tier-two supplement, one for sleep latency, duration and quality. He frames it as a timing signal, not a sedative. He notes the trials showing indirect body composition effects, along with grogginess and vivid dreams as side effects.

    Consistently lukewarm about melatonin for healthy adults with ordinary insomnia, though he accepts its usefulness for jet lag and circadian shifting.

    The problem is that’s not how people use melatonin, that people are using it for six months, 12 months, five years. And therefore I don’t think we’ve got any scientific data to meaningfully tell the public that they should not have these concerns, in my humble opinion too.
