Magnesium

Magnesium is very important for the normal functioning of cells, nerves, muscles, bones, and the heart. Usually, a well-balanced diet provides normal blood levels of magnesium. However, certain situations cause your body to lose magnesium faster than you can replace it from your diet.

Magnesium is very important for the normal functioning of cells, nerves, muscles, bones, and the heart. Usually, a well-balanced diet provides normal blood levels of magnesium. However, certain situations cause your body to lose magnesium faster than you can replace it from your diet. These situations include treatment with "water pills" (diuretics such as furosemide, hydrochlorothiazide), a poor diet, alcoholism, or other medical conditions (e.g., severe diarrhoea/vomiting, stomach/intestinal absorption problems, poorly controlled diabetes).

Magnesium is an essential dietary mineral, and the second most prevalent electrolyte in the human body. Magnesium deficiencies are common in developed countries. A deficiency increases blood pressure, reduces glucose tolerance and causes neural excitation.

Magnesium deficiencies are common in the western diet because grains are poor sources of magnesium. Other prominent sources of magnesium, like nuts and leafy vegetables, are not eaten as often. It is possible to fix a magnesium deficiency through dietary changes. If magnesium is supplemented to attenuate a deficiency, it acts as a sedative, reducing blood pressure and improving insulin sensitivity.

Maintaining healthy magnesium levels is also associated with a protective effect against depression and ADHD. Supplementation of magnesium is not very effective at reducing fat mass or cramps. Further evidence is needed to determine if magnesium supplementation can boost exercise performance, but initial results do not look promising.

The intestinal absorption of magnesium varies depending on how much magnesium the body needs, so there are not very many side-effects associated with supplementation. If there is too much magnesium, the body will only absorb as much as it needs. However, excessive doses may cause gastrointestinal distress and diarrhoea.

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 (such as antacids and 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. Magnesium is required for energy production, oxidative phosphorylation, and glycolysis. It contributes to the structural development of bone and is required for the synthesis of DNA, RNA, and the antioxidant glutathione. Magnesium also plays a role in the active transport of calcium and potassium ions across cell membranes, a process that is important to nerve impulse conduction, muscle contraction, and normal heart rhythm.

Overview Information

Magnesium is a mineral that is important for normal bone structure in the body. People get magnesium from their diet, but sometimes magnesium supplements are needed if magnesium levels are too low. Dietary intake of magnesium may be low, particularly among women. Magnesium deficiency is also not uncommon among African Americans and the elderly. 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.

People take magnesium by mouth to prevent magnesium deficiency. It is also used as a laxative for constipation and for preparation of the bowel for surgical or diagnostic procedures. It is also used as an antacid for acid indigestion.

Some people use magnesium for diseases of the heart and blood vessels including chest pain, irregular heartbeat, high blood pressure, high levels of "bad" cholesterol called low-density lipoprotein (LDL) cholesterol, low levels of "good" cholesterol called high-density lipoprotein (HDL) cholesterol, heart valve disease (mitral valve prolapse), metabolic syndrome, clogged arteries (coronary artery disease), stroke, and heart attack.

Magnesium is also used for treating attention deficit-hyperactivity disorder (ADHD), anxiety, chronic fatigue syndrome (CFS), Lyme disease, fibromyalgia, cystic fibrosis, alcoholism, mania, recovery after surgery, leg cramps at night and during pregnancy, diabetes, kidney stones, migraine headaches, a long-term pain condition called complex regional pain syndrome, weak bones (osteoporosis), premenstrual syndrome (PMS), altitude sickness, urinary incontinence, a condition that causes burning pain and redness called erythromelalgia, restless leg syndrome, asthma, hayfever, multiple sclerosis, and for preventing hearing loss and cancer.

Athletes sometimes use magnesium to increase energy and endurance.

Magnesium deficiency is common

Food processing removes much of the magnesium naturally present in foods such as seeds and grains, so deficiency is widespread.

Adults need around 375mg per day according to the EU Nutrient Reference Value or 400mg according to the US Daily Value. However, average adult intakes in Europe and the US are around 323 mg for males and 228mg for females. At least 65% of adults have low intakes, rising to over 80% by the age of 70 plus. Almost half (48%) of the US population overall have intakes that are below the recommended levels.

Symptoms that can result from magnesium deficiency include:

  • loss of appetite
  • nausea
  • fatigue
  • muscle weakness, trembling or cramps
  • numbness and tingling
  • poor co-ordination
  • palpitations
  • constipation.

Clinical Research

The effect of magnesium supplementation on primary insomnia in elderly: A double-blind placebo-controlled clinical trial
Nearly 50% of older adults have insomnia, with difficulty in getting to sleep, early awakening, or feeling unrefreshed on waking. With aging, several changes occur that can place one at risk for insomnia, including age-related changes in various circadian rhythms, environmental and lifestyle changes, and decreased nutrients intake, absorption, retention, and utilization. The natural N-methyl-D-aspartic acid (NMDA) antagonist and GABA agonist, Mg2+, seems to play a key role in the regulation of sleep. The objective of this study was to determine the efficacy of magnesium supplementation to improve insomnia in elderly.

Conclusion:

Supplementation of magnesium appears to improve subjective measures of insomnia such as ISI score, sleep efficiency, sleep time and sleep onset latency, early morning awakening, and likewise, insomnia objective measures such as concentration of serum renin, melatonin, and serum cortisol, in elderly people.
