Magnesium, an abundant mineral in the body, is naturally present in many foods, added to other food products, available as a dietary supplement, and present in some medicines (e.g., antacids, laxatives). Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation [1-3].

Supplements can contain a variety of different forms of magnesium, and the absorption of these forms varies. In general, forms of magnesium that dissolve well in liquid have higher absorption than other forms, and the aspartate, citrate, lactate, and chloride forms of magnesium tend to have higher bioavailability than magnesium oxide and magnesium sulfate.

Magnesium supplements are available in a variety of forms, including magnesium oxide, citrate, and chloride [2 ,3 ]. The Supplement Facts panel on a dietary supplement label declares the amount of elemental magnesium in the product, not the weight of the entire magnesium-containing compound.

The absorption of magnesium from different kinds of magnesium supplements varies. Forms of magnesium that dissolve well in liquid are more completely absorbed in the gut than less soluble forms [2 ,12 ]. Small studies have found that magnesium in the aspartate, citrate, lactate, and chloride forms is absorbed more completely and is more bioavailable than magnesium oxide and magnesium sulfate [12-16 ].

One study found that very high doses of zinc from supplements (142 mg/day) can interfere with magnesium absorption and disrupt the magnesium balance in the body [17 ].

Although the risk of acquiring too much magnesium from food is low among healthy people, high doses of magnesium from dietary supplements or medications can cause diarrhea, nausea, and abdominal cramping. Very high doses of magnesium can lead to magnesium toxicity, which can cause hypotension, vomiting, difficulty breathing, irregular heartbeat, cardiac arrest, and other signs and symptoms. A few cases of fatal hypermagnesemia have been reported.

The Tolerable Upper Intake Level for supplemental magnesium is 350 mg for adults, and it ranges from 65 to 350 mg for children and adolescents, depending on age.

Too much magnesium from food does not pose a health risk in healthy individuals because the kidneys eliminate excess amounts in the urine [29 ]. However, high doses of magnesium from dietary supplements or medications often result in diarrhea that can be accompanied by nausea and abdominal cramping [1 ]. The forms of magnesium that are most commonly reported to cause diarrhea include magnesium carbonate, chloride, gluconate, and oxide [12 ].

The diarrhea and laxative effects of magnesium salts are due to the osmotic activity of unabsorbed salts in the intestine and colon and the stimulation of gastric motility [57 ].

Very large doses of magnesium-containing laxatives and antacids (typically those that provide >5,000 mg/day magnesium) have been associated with magnesium toxicity [58 ], including fatal hypermagnesemia in a 28-month-old boy [59 ] and an elderly man [60 ].

Signs and symptoms of magnesium toxicity, which usually develop after serum concentrations exceed 1.74 to 2.61 mmol/L, can include hypotension, nausea, vomiting, facial flushing, retention of urine, ileus, depression, and lethargy before progressing to muscle weakness, difficulty breathing, extreme hypotension, irregular heartbeat, and cardiac arrest [29 ].

The risk of magnesium toxicity increases with impaired renal function or kidney failure because the ability to remove excess magnesium is reduced or lost [1 ,29 ].

The FNB has established ULs for supplemental magnesium for healthy infants, children, and adults (see Table 3) [1 ]. For many age groups, the UL appears to be lower than the RDA. This occurs because the RDAs include magnesium from all sources—food, beverages, dietary supplements, and medications. The ULs only include magnesium from dietary supplements and medications; they do not include magnesium found naturally in food and beverages.
