Yes and no: By definition if the levels are normal they should not be deficient. But, it is possible. Also, one should check not only magnesium serum levels but magnesium rbc levels. Still, there are many instances when normal levels are still causing cramping and supplementation helps......

Calcium: Check your calcium and serum albumen (because it's the ionized calcium that counts - there's a formula for determining ionized calcium based on albumen and the measured serum calcium.) low serum calcium is more likely to cause muscular irritability than low mag which causes arrhythmias.
