Magnesium Role in Human Body and Men's Health

Magnesium is a nutrient that is essential for hundreds of metabolic processes and many other important bodily functions starting from producing energy to building important proteins like DNA (Genetic material)(1).

Magnesium is the fourth most abundant mineral and the second most abundant intracellular element and has been recognized as a cofactor for >300 metabolic reactions in the body.

Magnesium is required for the proper growth and maintenance of bones. Magnesium is also required for the proper function of nerves and muscles.

Magnesium is most commonly used for constipation, as an antacid for heartburn, for pregnancy complications called pre-eclampsia and eclampsia, and for certain types of irregular heartbeat (torsades de pointes)(3).

What are the Signs of Low Magnesium in the Body?

  • Low levels of magnesium are linked to a number of health conditions, such as Type 2 diabetes, heart disease, and Alzheimer’s(2).
  • Low magnesium levels in the body have been linked to diseases such as osteoporosis, high blood pressure, clogged arteries, hereditary heart disease, diabetes, and stroke(4).
  • Low Magnesium levels also have been linked to chronic diseases, including migraine headaches and hypertension.

Best Dietary Sources of Magnesium

Our body can’t produce magnesium, so we need to obtain it from our diet. This can be achieved by eating magnesium-rich foods or by taking supplements.

An easy way to remember foods with good amounts of magnesium is to think of fiber.

Magnesium is present in legumes, whole grains, vegetables (especially broccoli, squash, and green leafy vegetables), seeds, and nuts (especially almonds)(5).

Other sources include dairy products, meats, chocolate, and coffee. Water with high mineral content, or “hard” water, is also a source of magnesium.

Magnesium in Our Body

Approximately 45-50% of magnesium in our body is present in bones, 45-50% is in the tissues and organs, and the rest is in the blood(6,7).

Some of the processes in which magnesium is a cofactor include, but are not limited to, protein synthesis, cellular energy production and storage, reproduction, DNA and RNA synthesis, and stabilizing mitochondrial membranes(6,7).

Magnesium also plays a critical role in maintaining normal nerve and muscle function, cardiac excitability (normal heart rhythm), neuromuscular conduction, muscular contraction, vasomotor tone, normal blood pressure, bone integrity, and glucose and insulin metabolism(8).

The Dietary Reference Intake for magnesium for adults is 310-420 mg/d; magnesium intake is often below these recommendations, particularly as people age(9).

Health Benefits of Magnesium

  • Can Reduce Blood Pressure(10-12)
  • May Improve Mood(13-15)
  • May Benefit Blood Sugar Control(16,17)
  • May Reduce Heart Disease Risk(18-21)
  • May Improve Migraine(2,22,23)
  • Testosterone Support(24-26)

Symptoms of Low Magnesium

Hypomagnesemia is a relatively common occurrence in clinical medicine. Magnesium deficiency has been found in 84% of postmenopausal women with osteoporosis, diagnosed with low magnesium trabecular bone content.

Magnesium is essential for the normal metabolism of potassium and calcium also. The occurrence in clinical situations of otherwise unexplained hypokalemia (potassium depletion) and hypocalcemia (calcium depletion from bone) should suggest the possibility of significant magnesium deficiency.

Other clinical features of magnesium deficiency include mental disturbances such as depression, confusion, agitation, hallucinations, weakness, neuromuscular irritability (tremor), athetoid movements, and convulsive seizures(27).

What Are the Side Effects of Magnesium?

Magnesium is relatively safe when taken in prescribed amounts.

Does Magnesium Interact with Other Drugs?

There may be mild to moderate interaction with the following classes of medicines.

  • Antibiotics (Aminoglycoside antibiotics)
  • Antibiotics (Quinolone antibiotics)
  • Antibiotics (Tetracycline antibiotics)
  • Bisphosphonates
  • Medications for high blood pressure
  • Muscle relaxants
  • Potassium-sparing diuretics)
