Magnesium is a critical element because hundreds of enzymatic reactions in the body depend on it. Muscles need magnesium for the process of contraction and relaxation. The heart needs this element to have a steady beat. The immune system needs it to eliminate inflammation. The blood vessels need magnesium so they can adequately expand and contract, thus controlling blood pressure.
Magnesium is just as important as zinc and chromium for proper blood sugar regulation. It makes insulin work better in the body. New research reports state that even the process of energy production (getting energy from fats and carbohydrates) and the synthesis of proteins are dependent on magnesium.
The RBC magnesium test is very similar to the serum test, but it measures the amount of magnesium in red blood cells rather than the magnesium in the blood serum. The RBC test is viewed as more accurate than the serum test because when you are deficient in magnesium, your body takes it from cells instead, therefore, making it highly detectable through an RBC. The RBC may indicate that these red blood cells are missing a healthy level of magnesium, meaning you may have a magnesium deficiency.
Dietary sources of magnesium include dark green leafy vegetables, lentils, beans, grains (unprocessed), and nuts.
Normal Ranges for Magnesium in mg/dL:
