Magnesium is essential for over 300 bodily functions, including energy production, nerve function, and heart health—yet nearly half of Americans don’t get enough. With a growing supplement market, many forms are available, but not all are equal. The top ways to assess them include bioavailability, elemental potency, and clinical efficacy. Sucrosomial magnesium and MagShape microcapsules rate highest overall, while magnesium oxide offers strong potency at a lower cost. Forms like magnesium L-threonate show specific health benefits despite lower absorption. The best choice depends on your goal: general magnesium support or targeting specific concerns like sleep, mood, or cognition.
