See the scientific wording

Supplementation with magnesium glycinate improves sleep quality and reduces insomnia in adults with sleep problems.

Why this might work

Magnesium glycinate supplies extra magnesium and glycine to the body. Magnesium calms brain cells by making the natural 'calm-down' signals stronger, and it also relaxes muscles by helping them stop contracting. Glycine is another calming chemical that quiets brain activity and lowers body temperature, which is a signal that triggers sleep. Together, these effects reduce stress and tension, making it easier to fall asleep and sleep deeply.

  1. Study: Magnesium Bisglycinate Supplementation in Healthy Adults Reporting Poor Sleep: A Randomized, Placebo-Controlled Trial

    In a study, people who took magnesium glycinate had a slightly bigger improvement in their sleep problem scores than those who took a fake pill, so it does help a little bit with sleep.
