Are you close to a AA battery? If so, decide it up and really feel its weight. That’s roughly how a lot of the mineral magnesium you may have in your physique — about 25 grams, or rather less than an oz. Magnesium has many well being advantages, and performs a significant function in lots of bodily features, but it will get nearly no press in comparison with its extra well-known buddies, iron and calcium.
While magnesium abounds in nature — it’s the seventh most typical ingredient on earth, by weight — we aren’t getting almost sufficient of it to realize and keep optimum well being. Somewhere between 10-30% of individuals worldwide — and round 50% of Americans — seem like poor. Magnesium deficiency is so frequent and widespread that it’s been referred to as a public well being disaster.
And compounding the issue is the truth that it’s laborious to precisely measure magnesium ranges within the physique. Tests have a look at serum magnesium (within the blood) and never intracellular magnesium (the focus of magnesium inside cells, the place it’s wanted). It’s somewhat like making an attempt to determine the monetary well being of a financial institution by counting the cash within the Brinks vans going to and from the constructing. There’s some relationship, nevertheless it’s removed from the entire story.
But what precisely does magnesium do in your physique? What are the well being advantages of magnesium? And why are so many people poor lately? Read on to seek out out!

It’s a cofactor concerned in over 300 enzyme methods that regulate biochemical reactions. And it’s a obligatory part for vitality manufacturing, DNA and RNA synthesis, and muscle and nerve perform.
Magnesium can also be an electrolyte, which implies it carries an electrical cost when dissolved in bodily fluids like blood. However, the vast majority of magnesium in your physique is uncharged and is sure to proteins or saved in your skeleton. Approximately half of the magnesium in your physique is present in bone, with little or no circulating in blood. In reality, lower than 1% of your physique’s magnesium is in your bloodstream. And it stays very tightly managed — primarily by your kidneys — which decide magnesium excretion or retainment.
6 Magnesium Health Benefits

1. Improved coronary heart well being
A 2017 meta-analysis of 11 research revealed in Nutrition Journal concluded that magnesium ranges circulating within the blood are inversely related to the incidence of coronary heart illness and hypertension. While extra analysis is required to find out optimum serum ranges of magnesium, researchers have been capable of determine increased ranges as having a protecting impact on coronary heart well being. Specifically, for each Zero.1 mmol/L enhance in circulating magnesium, there was a Four% decrease incidence of hypertension.
Furthermore, a 2005 research reviewed 20 randomized trials and located that administering intravenous or intramuscular magnesium previous to coronary heart surgical procedure was efficient in stopping post-operative atrial fibrillation (AF), or irregular heartbeat. Blood clots, stroke, coronary heart failure, and different problems may result from AF.
In different analysis, magnesium supplementation has additionally been helpful in decreasing hypertension, particularly amongst individuals with insulin resistance, prediabetes, and different high-risk teams.

This means that getting sufficient magnesium within the weight loss program might assist keep musculoskeletal well being as you age and even forestall osteoporosis and bone fractures.
Three. May assist forestall kind 2 diabetes
In addition to the hyperlink between magnesium and coronary heart well being, the 2017 meta-analysis talked about above additionally discovered that increased circulating ranges of magnesium have been related to a decrease threat for growing kind 2 diabetes. However, there was no dedication of optimum blood ranges but. A 2016 research revealed in Nutrients evaluated the dose-response relationship between magnesium consumption and sort 2 diabetes threat, taking a look at 25 research, together with 637,922 people, 26,828 of whom had the illness. After adjusting for BMI and age, the authors have been capable of determine a Eight-13% discount in threat for kind 2 diabetes for each 100 mg/day increment of dietary magnesium consumption.
Four. May enhance sleep patterns and high quality
Magnesium is understood to have a relaxing impact for many individuals, which can assist enhance sleep. This might have substantial well being advantages, contemplating that an estimated 50% of older adults have some extent of insomnia, or problem sleeping at night time. A 2012 research revealed within the Journal of Research in Medical Sciences discovered that 500 mg of supplemental magnesium, taken every day for eight weeks, resulted in subjectively improved sleep patterns amongst aged people with insomnia, in comparison with a placebo group. Although complete sleep time didn’t considerably differ between the 2 teams, those that obtained magnesium reported higher sleep high quality and fewer waking at night time and early morning. In a 1998 research, a small group of older adults with insomnia got 12.Four mmol of magnesium supplementation every day for 4 to 6 weeks. The research members discovered that charges of stressed leg syndrome decreased and that general sleep effectivity improved.
5. May cut back and forestall migraines
A closely studied well being good thing about magnesium is the connection between magnesium and migraines. Many researchers consider that magnesium deficiency might set off waves of altered cortical exercise, clumping of blood platelets within the mind, constricted blood vessels, and launch of sure neurotransmitters that may result in migraines. How a lot magnesium helps? Research on that is inconsistent, maybe partially as a result of not everybody has the identical degree of want.

- Magnesium glycinate comprises the amino acid glycine, which works with mind neurotransmitters like GABA to advertise calmness and enhance sleep. It additionally has an anti-inflammatory impact, however doesn’t work as nicely for assuaging constipation.
- Magnesium gluconate treats magnesium deficiency. It seems to have the best bioavailability amongst magnesium salts.
- Magnesium chloride is a magnesium salt mixed with chlorine. It’s well-absorbed and sometimes prescribed for heartburn, magnesium deficiency, and constipation.
