Magnesium

Shortfalls of this mineral may show up as muscle cramps and twitches, anxiety, fatigue, irritability, poor concentration and headaches, among other symptoms. Long-term use of acid-reflux drugs called proton pump inhibitors may lead to magnesium deficiency.

Tip: If you supplement with calcium, take magnesium, too. Experts suggest a 2:1 calcium-to-magnesium ratio.

Daily dose: 100−600 mg as magnesium glycinate or magnesium citrate
