Outcome
    Preliminary

    Magnesium for Jet Lag Recovery

    Magnesium has no circadian-shifting effect and is not a jet lag treatment.

    Overview

    Magnesium has no circadian-shifting effect and is not a jet lag treatment.

    Verdict

    Insufficient evidence

    How It Works

    Magnesium supports sleep quality generally but does not act on the suprachiasmatic clock.

    Evidence is insufficient. Jet lag is circadian misalignment, and correcting it requires shifting the body clock - which is achieved by timed bright light exposure and, where appropriate, melatonin, a genuine chronobiotic with good trial evidence for eastward travel across several time zones. Magnesium does none of this. No trial has examined magnesium for jet lag. The indirect argument is that magnesium modulates melatonin synthesis and improves sleep quality in people with low status, so it might ease sleep onset at the destination - but that addresses a symptom rather than the misalignment, and has not been tested in travellers. Magnesium also has no effect on the timing of the circadian clock, which is the entire problem in jet lag.

    Evidence

    What the studies say

    No controlled trials address magnesium for jet lag or phase shifting.

    No studies are yet linked to both Magnesium and Jet Lag Recovery.

    Safety

    Caveats

    Prioritise timed light and melatonin.

    Less likely to help if

    Everyone: magnesium does not shift circadian phase and has no jet lag data.
