Where is magnesium located in the body?
Magnesium in the body is represented as either extracellular 1% (that is, outside the cell) or intracellular 99% (inside the cells). Approximately half the magnesium is in the bones and most of the rest is in the muscles and soft tissues. Because most of the magnesium is in the cells instead of in the blood, a blood test to determine magnesium is an inaccurate estimate of levels in the body in general. However, a live blood analysis may show the signs of the body’s needs. An analogy I like to use to describe the magnesium in and out the cells and how we can’t be sure if a blood test reflects our true levels in the body, is one of an expressway and city parking. If the expressway into a city is our blood vessels, the cars are magnesium, and the car parking spaces in the city our cells or storage spaces in our body then we can see that at times, say peak hour, we can have the expressway full of cars and nothing in the carpark, but at say 10am the car spaces are full up, but the expresswa
