11 subtle warning signs may point to low magnesium intake, experts said, including fatigue, muscle cramps, anxiety, irregular heartbeat, headaches and trouble sleeping.
Up to half of Americans may not get enough magnesium even though true deficiency affects only about 2% of healthy adults, largely because diets lack magnesium-rich vegetables and processed foods lose minerals during refining.

Magnesium supports energy production, muscle and nerve function, blood pressure, blood sugar and bone health, so low intake can also show up as mood swings, constipation, sugar cravings, high blood pressure and weaker bones.
