“For jet lag, you take it at the target destination's bedtime to reset your circadian phase.”
For jet lag, melatonin should be taken at the target destination's bedtime to reset circadian phase.
None of the 10 provided studies directly address melatonin dosing timing for jet lag or circadian phase resetting. The studies cover topics such as PCOS, IVF, cardiovascular risk, ICU use, TBI, and ge…
“Always disclose to your prescriber.”
Melatonin use should always be disclosed to one's prescriber.

“For most patients with general sleep onset difficulty, lower doses — 0.5 to 1 milligram — are more appropriate and often equally or more effective.”
For most patients with general sleep onset difficulty, lower doses of 0.5 to 1 milligram are more appropriate and often equally or more effective.
The expert's claim specifically concerns low-dose melatonin (0.5–1 mg) for sleep onset difficulty in general adult patients. None of the 10 provided studies directly address melatonin dosing for this…
