Magnesium is a vital nutrient that is often deficient in modern diets. Our ancient ancestors would have had a ready supply from organ meats, seafood, mineral water, and even swimming in the ocean, but modern soils can be depleted of minerals and magnesium is removed from water during routine municipal treatment. The current RDA for adults is between 320 and 420mg daily, and the average US intake is around 250mg daily.
Does it matter if we are a little bit deficient? Well, magnesium plays an important role in biochemical reactions all over your body. It is involved in a lot of cell transport activities, in addition to helping cells make energy aerobically or anaerobically. Your bones are a major reservoir for magnesium, and magnesium is the counter-ion for calcium and potassium in muscle cells, including the heart. If your magnesium is too low, you can experience muscle cramps, arrythmias, and even sudden death. Ion regulation is everything with respect to how muscles contract and nerves send signals. In the brain, potassium and sodium balance each other. In the heart and other muscles, magnesium pulls some of the load.
That doesn't mean that magnesium is unimportant in the brain. Au contraire! In fact, there is an intriguing article entitled Rapid recovery from major depression using magnesium treatment, published in Medical Hypothesis in 2006. Medical Hypothesis seems like a great way to get rampant (but referenced) speculation into the PubMed database. Fortunately, I don't need to publish in Medical Hypothesis, as I can engage in such speculation in my blog, readily accessible to Google. Anyway, this article was written by George and Karen Eby, who seem to run a nutrition research facility out of an office warehouse in Austin, Texas - and it has a lot of interesting information about our essential mineral magnesium.
Magnesium is an old home remedy for all that ails you, including "anxiety, apathy, depression, headaches, insecurity, irritability, restlessness, talkativeness, and sulkiness." In 1968, Wacker and Parisi reported that magnesium deficiency could cause depression, behavioral disturbances, headaches, muscle cramps, seizures, ataxia, psychosis, and irritability - all reversible with magnesium repletion.
Stress is the bad guy here, in addition to our woeful magnesium deficient diets. As is the case with other minerals such as zinc, stress causes us to waste our magnesium like crazy - I'll explain a bit more about why we do that in a minute.
