Magnesium is both a vital mineral and an electrolyte crucial for body functions. Most magnesium is stored in bones and tissues, with only a small amount in the bloodstream. Blood magnesium levels between 0.75 and 0.95 millimoles per liter are normal; levels below this indicate magnesium deficiency, or hypomagnesemia. Blood tests may not fully reflect magnesium levels, as assessing the mineral’s status remains tricky. Other methods like saliva and urine tests exist but are not fully reliable.

Magnesium deficiency can result from poor diet, chronic diseases, alcohol abuse, medications, and surgeries. Recommended daily intake for men is 400-420mg, and for women, it ranges from 310-320mg, depending on age. Pregnant and lactating women need higher amounts. Deficiency symptoms include “muscle twitches and cramps, high blood pressure, and mental health conditions.”

Around 2% of the general population suffers from magnesium deficiency, but rates rise to 10%-20% in hospitalized patients and up to 50%-60% in intensive care. People with alcohol abuse disorder show even higher deficiency rates, ranging from 30% to 80%.

Magnesium can be found in various foods like “pumpkin seeds, almonds, spinach, and bananas.” Supplements are also available in different forms, such as magnesium citrate and glycinate. However, always consult a doctor before starting supplements, especially when on medication.
