Understanding magnesium
What it does
Magnesium is a mineral involved in more than 300 enzyme reactions, including those that produce energy, build protein, and support muscle and nerve function. It also helps regulate blood sugar and blood pressure and contributes to bone structure. Every cell in the body needs it to work.
When intake falls short
Surveys suggest about half of Americans get less magnesium from food than recommended, with teenagers and older men most likely to fall short. Ordinary low intake rarely causes obvious symptoms because the body regulates blood levels tightly, but chronic shortfalls may affect long-term health. Diets heavy in refined foods and light on whole plants are the usual culprit.
Absorption & pairing
Magnesium is plentiful in whole foods but is stripped out when grains are refined, so choosing whole grains preserves it. Very high doses from supplements can cause diarrhea, another reason food sources are preferable for most people.
Food-first strategy
Lean on green leafy vegetables, nuts, seeds, legumes and whole grains, which are the richest everyday sources. A handful of pumpkin seeds or almonds, a serving of black beans, or a bowl of oatmeal each moves you toward the 420 mg Daily Value. Dark chocolate is a surprisingly good source too.
