Does magnesium help with sleep?

Magnesium is involved in nerve and muscle function and may support relaxation. Some studies suggest that magnesium supplementation might help improve sleep quality in people with low intake or deficiency, though evidence is not conclusive for everyone. Magnesium glycinate is often chosen for sleep support because it is well absorbed and glycine may have calming effects. Taking it in the evening with dinner or before bed is common. Avoid very high doses, which can cause loose stools. Sleep depends on many factors (schedule, stress, screen time, caffeine); magnesium may be one piece of the puzzle.
