A 32-year-old man presents to his primary care physician complaining of diffuse muscle weakness, dry and puffy skin, and patchy areas of hair loss on his scalp. He also notes numbness around his mouth and a tingling sensation in his hands and feet. He has a history of seizure disorder, and has been taking carbamazepine for the past 5 years. On physical examination he has dry skin and coarse, brittle hair with patchy alopecia. Tapping his right cheek causes contraction of the muscles at the corner of his mouth, nose, and eye on the right side. Which of the following could best have prevented the development of the patient’s current problem?
(A) Magnesium supplementation
(B) Parathyroidectomy
(C) Thyroid hormone
(D) Vitamin C supplementation
(E) Vitamin D supplementation
