Magnesium Deficiency Signs, Food Sources, and Supplement Guidance
Magnesium is a mineral your body uses for muscles, nerves, energy, and the heartbeat.
People usually get it from foods such as nuts, seeds, beans, leafy greens, and whole grains.
Not getting enough may sometimes be linked with cramps, tiredness, poor sleep, weakness, or mood changes.
More serious deficiency may involve tingling, nausea, or heart-rhythm problems.
However, these signs can happen for many different reasons.
Some health conditions, medicines, alcohol use, or problems absorbing nutrients can increase the risk of low magnesium.
Eating more magnesium-rich foods is usually a good first step.
Some people may consider supplements if food alone does not meet their needs.
Too much supplemental magnesium can cause diarrhea, so people should seek professional advice before using it.
Magnesium supports bones, electrolyte balance, energy metabolism, muscles, nerves, and normal heart rhythm.
Possible signs of inadequate magnesium include cramps, fatigue, poor sleep, weakness, mood changes, tingling, nausea, and irregular heartbeat.
These symptoms can have many causes and should not be used alone to diagnose magnesium deficiency.
Risk factors include a magnesium-poor diet, gastrointestinal conditions, long-term alcohol consumption, some medications, and nutrient-absorption problems.
Magnesium-rich foods include seeds, nuts, leafy greens, beans, lentils, whole grains, avocado, and high-cocoa dark chocolate; supplements require careful selection and medical advice.
