Magnesium is involved in more than 300 enzyme reactions in the body, from energy production to muscle and nerve function. Despite its importance, many people don't get enough.
Top food sources
Leafy greens, nuts, seeds, legumes, and whole grains are rich in magnesium. Pumpkin seeds, almonds, and spinach are especially good sources.
Should you supplement?
Most people can meet their needs through food. Supplements may help those with low intake or certain conditions — but check with your doctor, as too much can cause side effects.
