Study hypothesis: supplementary magnesium may influence the blood calcium level in treated hypoparathyroid patients. Patients will be treated with supplementary magnesium (350 mg/day) for 3 weeks. Calcium and other relevant blood parameters will be measured before the treatment, at the end of treatment and 2 weeks after stopping treatment.

Condition Intervention
Dietary Supplement: magnesium
