Less than 1% of our body’s total Mg can be measured in blood serum. Most of our Mg is found in bones – around 60% and inside muscle and other cells – around 40%.

Thus, the body makes sure that the amount of Mg in blood fluids is stable at all times, even when bodywide levels are low. This means, even if you are deficient in this mineral, your body will keep your blood serum magnesium level normal. So the antiquated blood serum test has no value in showing your real Mg levels.
