See the scientific wording

Magnesium supplementation in elderly individuals with primary insomnia is associated with a reduction in sleep onset latency by approximately 17 minutes and an increase in total sleep time by 16 minutes, based on pooled data from randomized controlled trials involving 151 participants.

Why this might work

Magnesium blocks overactive brain signals that keep you awake, calms the brain by boosting a natural sleep chemical, and helps the body make more of the hormone that tells it when to sleep, leading to faster sleep onset and longer sleep.
