Why do we need magnesium?

Did you know?

Many adults (older adults especially) have inadequate intakes of calcium in their diets and are prone to deficiency. fitness, sport, people, exercising and lifestyle concept - couple running upstairs on city stairs An essential nutrient, magnesium drives an astounding array of important processes in our body through its involvement in more than 600 enzymatic reactions, including energy metabolism and protein synthesis. Magnesium regulates muscle and nerve function, blood sugar levels, and blood pressure. It’s also necessary for making protein, bone, and DNA.

Did you know?

Every cell in our body contains magnesium—and needs it to function. Bone contains about 60 percent; the remainder of the body’s magnesium is found in muscles, soft tissues, and fluids (including blood).

Health benefits of magnesium

Further research is uncovering many opportunities for magnesium supplementation in boosting health through prevention and treatment.

Type 2 diabetes

Because of its crucial role in insulin production, magnesium deficiencies are closely linked to type 2 diabetes. It’s thought that elevated blood glucose levels increase the loss of magnesium in the urine, which in turn lowers blood levels of magnesium. Up to 48 percent of those with type 2 diabetes have been found to be deficient.

The research

Researchers have long known that those with magnesium deficiencies are at higher risk of developing type 2 diabetes, so many studies have found benefits of magnesium supplementation in both prevention and treatment of diabetes.

Studies involving magnesium supplements have shown improved fasting and postprandial (before or after eating) glucose levels and insulin sensitivity as well as improved insulin sensitivity in nondiabetic people with insulin resistance.

Blood pressure

The research

A European meta-analysis of 22 trials concluded that supplementing with magnesium appears to achieve a small but clinically significant reduction in blood pressure. And a more recent 2017 meta-analysis of 11 randomized controlled trials found that magnesium supplementation significantly lowered blood pressure in individuals with insulin resistance, prediabetes, or other noncommunicable chronic diseases.

Some researchers believe that people who suffer from migraines are more likely than others to be magnesium deficient.

The research

A systematic review, just published this year, of five randomized, double-blind, placebo-controlled trials studying the effect of magnesium supplementation on migraine prevention gave it a Grade C—“possibly effective.” In the conservative world of medical research reviews, this outcome was a very positive signal for the role of magnesium supplementation in reducing the number of attacks in migraine sufferers.

Depression

Researchers have learned that it triggers changes in the brain’s synapses, the neuronal connections important for transmitting nerve signals. It’s thought to play a role in many of the biological processes involved in mood regulation. Many studies have also found a link between magnesium deficiency and symptoms of depression.

The research

In a 2017 study, 126 adults with mild or moderate depression took magnesium supplements for six weeks and none for another six weeks. Participants scored an average of six points lower on the depression scale (measured using the standard Patient Health Questionnaire 9) during the six weeks of taking magnesium supplements than when they didn’t take the supplements.

The research

Magnesium supplementation has been found to help alleviate PMS symptoms, but in a 2010 study, the improvements increased when magnesium was taken alongside vitamin B6 supplements. Symptoms most affected in this study included anxiety, irritability, bloating, abdominal discomfort, nausea, flushing, low back pain, headache, acne, and muscular pain.

It’s also involved in disposing lactic acid that builds up when we’re exercising, which can cause pain and reduce performance. While we’re involved in strenuous exercise, magnesium requirements can increase by as much as 10 to 20 percent.

The research

Plenty of studies have shown benefits in exercise performance through magnesium supplementation. A 2014 study involving healthy older women found that daily magnesium supplementation over 12 weeks improved their physical performance, while volleyball players who received daily magnesium supplementation over four weeks showed decreased lactic acid production and significant increases in sport-related movements.

Check with your health care practitioner to find out how supplementing with magnesium might work for you.
