Answer

Recommended treatment for vitamin D–deficient patients who are obese, have a malabsorption syndrome, or are taking medication that affects vitamin D metabolism, is as follows [2] :

  • At least 6000-10,000 IU of vitamin D daily

  • When the serum 25(OH)D level exceeds 30 ng/mL, provide maintenance treatment of 3000-6000 IU/day
