Are you close to a AA battery? If so, choose 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 position in lots of bodily capabilities, but it will get virtually no press in comparison with its extra well-known buddies, iron and calcium.
While magnesium abounds in nature — it’s the seventh most typical factor on earth, by weight — we aren’t getting practically sufficient of it to attain and keep optimum well being. Somewhere between 10-30% of individuals worldwide — and round 50% of Americans — look like poor. Magnesium deficiency is so widespread and widespread that it’s been referred to as a public well being disaster.
And compounding the issue is the truth that it’s onerous 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 a bit of like attempting 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, but it surely’s removed from the entire story.

1. Improved coronary heart well being
A 2017 meta-analysis of 11 research printed 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 in a position to establish larger 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 examine 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 useful in reducing hypertension, particularly amongst individuals with insulin resistance, prediabetes, and different high-risk teams.

This means that getting sufficient magnesium within the food plan may assist keep musculoskeletal well being as you age and even stop osteoporosis and bone fractures.
Three. May assist stop sort 2 diabetes
In addition to the hyperlink between magnesium and coronary heart well being, the 2017 meta-analysis talked about above additionally discovered that larger circulating ranges of magnesium have been related to a decrease threat for creating sort 2 diabetes. However, there was no dedication of optimum blood ranges but. A 2016 examine printed in Nutrients evaluated the dose-response relationship between magnesium consumption and sort 2 diabetes threat, 25 research, together with 637,922 people, 26,828 of whom had the illness. After adjusting for BMI and age, the authors have been in a position to establish a Eight-13% discount in threat for sort 2 diabetes for each 100 mg/day increment of dietary magnesium consumption.
Four. May enhance sleep patterns and high quality
Magnesium is thought to have a chilled impact for many individuals, which can assist enhance sleep. This may have substantial well being advantages, contemplating that an estimated 50% of older adults have a point of insomnia, or problem sleeping at evening. A 2012 examine printed within the Journal of Research in Medical Sciences discovered that 500 mg of supplemental magnesium, taken each 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 acquired magnesium reported higher sleep high quality and fewer waking at evening and early morning. In a 1998 examine, a small group of older adults with insomnia got 12.Four mmol of magnesium supplementation each day for 4 to 6 weeks. The examine members discovered that charges of stressed leg syndrome decreased and that total sleep effectivity improved.
5. May cut back and forestall migraines
A closely studied well being advantage of magnesium is the connection between magnesium and migraines. Many researchers imagine 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 stage of want.
