A naturally produced hormone used at very low doses to support sleep onset.
How it works
Binds melatonin receptors in the suprachiasmatic nucleus to support circadian timing; effective doses are remarkably low.
Evidence
Melatonin at 0.3-1 mg has been studied for sleep-onset latency in healthy adults.
Studies
Brzezinski et al., Sleep Med Rev, 2005
Modest reductions in sleep-onset latency at low oral doses.
