The normal range for blood magnesium level is 1.7 to 2.2 mg/dL (0.85 to 1.10 mmol/L). Normal value ranges may vary slightly among different laboratories.
RDA: The Recommended Dietary Allowance (RDA) for adults 19-51+ years is 400-420 mg daily for men and 310-320 mg for women. Pregnancy requires about 350-360 mg daily and lactation, 310-320 mg.
If the level of magnesium in your blood is lower than 1.8 milligrams per deciliter, your levels are considered low. If your level is below 1.25 mg/dL, your condition is considered severe. Often, doctors may not find this condition until the levels are severely low.
Background. The normal plasma magnesium (Mg) concentration is maintained (primarily) by the kidney in the narrow range of 0.8 to 1.10 mmol/L.
For example, increased levels of magnesium may be seen with kidney disease because magnesium is excreted by the kidneys. A low magnesium level can be a sign of diabetes, some digestive problems, malnourishment, or long-term (chronic) alcoholism. Lower magnesium levels during pregnancy may mean preeclampsia.
Normal Results
The normal range for blood magnesium level is 1.7 to 2.2 mg/dL (0.85 to 1.10 mmol/L).
Refining or processing of food may deplete magnesium content by nearly 85%. Furthermore, cooking, especially boiling of magnesium-rich foods, will result in significant loss of magnesium. The processing and cooking of food may therefore explain the apparently high prevalence of low magnesium intake in many populations.
This mineral is involved in over 300 enzymatic processes in the body, including every major organ function—especially the heart and brain. But did you know that there is a link between magnesium deficiency and weight gain? Your body depends on magnesium for a lot of processes, like: Maintaining healthy DNA.
Brief Summary: Hypomagnesemia is a common entity in the inpatient and outpatient setting. in previous retrospective study hypomagnesemic patients have higher mortality and longer hospitalization.
Hypomagnesemia occurs with both loop diuretics (furosemide, bumetanide, torsemide, and ethacrynic acid) and thiazide diuretics (chlorothiazide, hydrochlorothiazide, indapamide, and metolazone).
Mg is essential in the metabolism of vitamin D, and taking large doses of vitamin D can induce severe depletion of Mg. Adequate magnesium supplementation should be considered as an important aspect of vitamin D therapy.
Chronic magnesium deficiency is often associated with normal serum magnesium despite deficiency in cells and in bone; the response to oral supplementation is slow and may take up to 40 weeks to reach a steady state.
One study shows that 68% of Americans are magnesium deficient (www.usda.gov). The role of magnesium is complex and its deficiency is implicated in a number of nonspecific neuropsychological changes such as agitation, fear, anxiety, depression, dizziness, poor attention, insomnia, and restlessness.
Every organ in the body, especially the heart, muscles, and kidneys, needs the mineral magnesium. It also contributes to the makeup of teeth and bones.
Magnesium supplements can cause nausea, cramps, and diarrhea. Magnesium supplements often cause softening of stool. Interactions. Magnesium supplements may interact with certain medicines, including diuretics, heart medicines, or antibiotics.
One study of older adults with insomnia found that magnesium supplementation at a dose of 500 milligrams daily for eight weeks helped them fall asleep faster, stay asleep longer, reduced nighttime awakenings, and increased their levels of naturally circulating melatonin.
Malnutrition: Starvation, anorexia, bulimia, or frequent vomiting for any reason can result in a magnesium deficiency. Digestive diseases: People with conditions such as Crohn's disease, celiac disease, or regional enteritis can have difficulty absorbing magnesium via the gut.
A health care practitioner may order a magnesium test to check for a deficiency as part of an evaluation of malabsorption, malnutrition, diarrhea, or alcoholism. Testing may also be performed when someone is taking medications that can cause the kidneys to excrete magnesium.
In the heart, magnesium plays a key role in modulating neuronal excitation, intracardiac conduction, and myocardial contraction by regulating a number of ion transporters, including potassium and calcium channels.
