Magnesium and sleep: promising, not proven

Few small trials, mostly in older adults, with low certainty. Magnesium is an essential mineral many adults under-consume.

The question

Does oral magnesium improve sleep?

Study design

Systematic review and meta-analysis of 3 randomized trials (151 older adults), 2021. ^[1][2]

What they found

Pooled results suggested people fell asleep about 17 minutes faster with magnesium, but the authors rated the evidence low quality. ^[1][2]

Limitations

Small samples, different forms and doses, short duration. L-threonate specific human sleep data are limited.

What this does not mean

Magnesium is not a sleep medication. Persistent sleep problems deserve a conversation with a clinician.
