Magnesium is a critically important nutrient in the body. It plays a major role in keeping the immune system functioning well and in keeping nerves healthy. Most of the magnesium in the body is found inside the cells and this makes it difficult to measure with a blood test as this measures only the magnesium outside of the body cells.
So, it is possible to have a “normal” level of magnesium on a blood test and still be significantly depleted of magnesium inside the cells. This occursÂ commonly today in the United States in patients with chronic Lyme Disease.
