Most people feel something within the first weeks.
Week 1: Falling asleep is easier. Fewer middle-of-the-night wake-ups. Cramps start to fade.
Week 2-3: You start sleeping through the night. Mornings feel different — less anxious, less foggy. Energy stabilizes.
Week 4+: The full effect kicks in. Your nervous system has rebuilt its magnesium stores. Stress doesn't spike the way it used to. Sleep becomes reliable.
Magnesium is a restoration, not a sedative. It takes a bit of consistency as 76% of Americans are already magnesium-deficient.
