Exercise's Dual Effect on Magnesium
Short bursts of exercise increase blood magnesium, but longer workouts deplete it below baseline.
This suggests a threshold where the body shifts from mobilizing to depleting magnesium.
insights INSIGHT
Magnesium and Brain Volume
Higher magnesium intake may correlate with larger brain volumes and reduced brain aging.
This observation, particularly notable in women, warrants further investigation with clinical trials.

Magnesium for Migraines
Consider 600mg/day of magnesium, split into smaller doses, to manage migraines.
This may help prevent cortical spreading depression and reduce pain-transmitting chemicals.
