Magnesium is involved in more than 300 chemical reactions in your body. It is not a nice-to-have. It is the mineral your cells use to make energy, regulate your nervous system, control blood sugar, build protein, and keep your heart beating in rhythm. About half of American adults fall short of the recommended daily intake.

Low magnesium often shows up as poor sleep, muscle cramps, anxiety, fatigue that doesn’t improve with rest, headaches, a racing heart, or constipation. If you have been living with any of those and you’re chalking them up to stress or aging, magnesium deficiency is worth ruling out first.

In the full version of this article you’ll learn:

  • Why almost everyone is low, and why your doctor’s blood test won’t catch it

  • What magnesium actually controls in your body, system by system

  • Which form of magnesium to take and why most people are taking the wrong one

  • How much to take, when to take it, and how to know if it’s working
