Magnesium is essential for every part of the body to function properly. It helps produce energy, is a cofactor for enzymes and helps regulate other nutrients including calcium, potassium, zinc and vitamin D. A magnesium deficiency is rare even if your child's diet is low in magnesium. However, certain conditions may create magnesium deficiencies such as diabetes, irritable bowel syndrome, hyperthyroidism and excessive diarrhea and vomiting.

Deficiency Symptoms in Children

Symptoms of a magnesium deficiency in children include nausea, vomiting, fatigue, loss of appetite and weakness. As the deficiency progresses, so do symptoms. These symptoms include muscle contractions, cramps, numbness, seizures and heart arrhythmias. When a severe deficiency occurs, low potassium and calcium levels occur. You shouldn't give your child magnesium supplements unless you are doing so under a doctor's supervision.
