is Magnesium the Mineral we All Need?
This month PART 1: background, digestion, muscle tension. Next month PART 2: bones, heart, brain, and emotions.
Magnesium is necessary for brain, nerve, and muscle function. It helps calcium absorb into the bones, regulates blood sugar and blood pressure, and supports DNA synthesis. Magnesium deficiency is associated with bone loss, high blood pressure, muscle cramps, brain disorders, tension and anxiety, and type 2 diabetes. Yet it is estimated that more than half of Americans do not consume the recommended (minimum) daily value (310-420 mg, depending on age and gender). Outright deficiencies are known to occur, and borderline deficiencies are strikingly common.
In the diet, we find magnesium in whole (unrefined) grains, beans and peas, nuts and seeds, fresh fruits and vegetables, some mineral waters, and dark chocolate. In other words, the things we leave behind when we adopts a modern, industrialized diet. Refining grains (the process that converts whole wheat to white flour) removes 80-90% of the magnesium. Alcohol, caffeine, and sugar deplete magnesium; calcium increases our need for magnesium.
And our dietary choices are only half the problem. Even if we choose the right foods – traditional whole foods – we still run the risk of deficiency. That’s because foods today are lower in magnesium than they used to be. First, modern high-yield crops tend to run lower in magnesium then their heirloom counterparts. And the soil they’re growing in is growing increasingly depleted. The difference is so large, scientists originally thought the nutrition measurements from the 1940s and 50s were flawed. The labwork was sloppy. The methodologies were inadequate. Finally, we’ve come to realize that labwork is valid. Instead, decades of NPK fertilizers have allowed the soil itself to become magnesium-deficient.
So we should all consider a magnesium supplement.
WHAT DOES MAGNESIUM DO?
Resolve Constipation: Magnesium can loosen and move the bowels. For some, this is a welcome improvement. For others, an unwanted side effect. Not to worry: we have a surprising amount of control over whether or not this is going to happen.
Here’s the deal: magnesium that doesn’t absorb stays in the gut (obviously…), where it creates a diffusion gradient that draws in water, which in turn moves the bowels. It’s simple, effective, safe and gentle (barring any crazy over-use), and non-habit forming
So, the trick is to take magnesium in such a way it overloads the body’s ability to absorb it. You do that by taking a lot all at once and/or by taking a form that absorbs poorly. Most people aim for 300-1,000 mg of elemental magnesium, all at once, as magnesium oxide or magnesium sulfate.
Conversely, if loosening the bowels is an unwanted side effect you’d rather avoid, you’ll want to focus on smaller doses, and better-absorbing forms like magnesium glycinate, aspartate, orotate, taurate etc.
Muscle Tension and Muscle Cramps: Magnesium relaxes muscles. To be clear, this isn’t some kind of high-level horse tranquilizer where you’ll be flopping around like a soggy fish. It just decreases baseline muscle tension. This is great if you’re naturally tense (include tension in the blood vessels, leading to high blood pressure: more about that later), or if you have frequent cramps, especially night-time leg cramps.
If you’re always tense in the shoulders… try some magnesium.
If your neck keeps on seizing up… try some magnesium.
Menstrual cramps… try some magnesium.
Back spasms… try some magnesium.
You can use magnesium orally, or a lotion or spray topically. I’ve honestly had mixed results with the topical stuff, although I find it’s more likely to help with chronic, baseline conditions than something acute like an emerging cramp. You can also go all-out with an epsom salts (magnesium sulfate) bath.
Where all this can really can be life changing is around night-time leg cramps. Magnesium has been researched for night-time leg cramps, more than once, and in these studies, it usually barely works. However, we sell a ton of it, to easily hundreds of customers, who keep on buying and using it, because it absolutely works. Why such a discrepancy between the research and real life? Well, all the published research uses poorly absorbing magnesium oxide and citrate. So a) it doesn’t work well to begin with; and b) even if it does, people drop out of the study due to “digestive disturbances.” Well, extrapolating from magnesium oxide to magnesium glycinate is like extrapolating from a moped to a Ferrari. Yes, they’re both motor vehicles. But only one of them is going to make it up the hill.
A standard dose to reduce muscle tension throughout the day is ~250 mg of elemental magnesium as magnesium glycinate, 2-3 times a day. You can diverge from that, though. A standard dose specific to night-time leg cramps is around 400 mg about an hour before bed.
