Magnesium Distribution in the Human Body [20,21,30,42,43,44].

Location	Magnesium Distribution
Bone	50–60% of total magnesium (24–29 g), with approximately one-third being exchangeable
Soft Tissues (muscles and other organs)	34–39% of total magnesium
Blood	Less than 1% of the body’s magnesium
Plasma	60% ionized, 30% bound to albumin, 10% complexed with serum anions (phosphate and citrate)
