Short answer

30-60 minutes before bed, as in one routine that pairs it with DHEA (Bryan Johnson). It is also used to reset circadian rhythm, especially for jet lag (Mark Hyman). The timing of light exposure matters more than the timing of melatonin (Andrew Huberman).

Full Protocol

Timing
30-60 minutes before bed, as in one routine that pairs it with DHEA (Bryan Johnson). It is also used to reset circadian rhythm, especially for jet lag (Mark Hyman). The timing of light exposure matters more than the timing of melatonin (Andrew Huberman).
Dosage
Low dose (0.3-1mg) if used at all. Most store doses (3-10mg) are far above natural levels (Andrew Huberman). Older adults may benefit from a low dose. One nightly routine does not state its dose (Bryan Johnson).
Form
No particular form (immediate-release or extended-release) is specified on tape. Sublingual forms may absorb faster. Melatonin also appears in a topical hair-growth formula (Bryan Johnson).
Notes
Supporting your own melatonin through light and behavior comes before pills. A common sleep stack, magnesium threonate (145mg), apigenin (50mg) and theanine (100-400mg), leaves melatonin out (discussed on Huberman Lab). Consider melatonin mainly for jet lag, shift work or older adults whose production has declined.
