There’s quite a bit of buzz about magnesium of late so I thought I’d sum up some of the highlights right here. First, what I personally find to be the most common reasons people gravitate to this mineral is for relaxation, to help with sleep, constipation and muscle cramping.
These symptoms are associated with deficiency of magnesium in our bodies and can be offset with intake of 400-800mg daily. It varies widely by individual. Second is its relationship with calcium. The body needs magnesium in order for calcium to be absorbed. At the cellular level, calcium provides energy and magnesium calms the cell, allowing the absorption.
Referenced in a recent article from Carolyn Dean, MD, ND, it’s reported that over 40% of the population uses supplements containing calcium and it isn’t balanced with sufficient levels of magnesium in the body (PR Newswire Email). The problem with this is that less than half of the calcium intake is absorbed in the gut and the rest is either excreted and can form kidney stones or transported to soft tissues where it can harden. That’s downright scary. Magnesium to the rescue! It converts vitamin D so that it can help with calcium absorption and it also stimulates a hormone called calcitonin, which not only preserves bone structure but also draws calcium out of the blood and soft tissues and back into the bones. So you can see how important the roll of magnesium is here, for heart health, bone health and, as mentioned earlier, sleep and muscle relaxation. And this just scratches the surface!
