| Obesity is associated with vitamin D deficiency. The reason is that the vitamin D is trapped within the fat and cannot easily exit. As a result, obese patients need at least twice as much vitamin D as a normal weighted individual in order to maintain a normal vitamin D status with a 25(OH)D between 30-60 ng/ml.

Example: I am a light skinned MN native who does not sun bathe. I am 30 pounds overweight. May I take as much as 20,000 IU a day (vitamin D) if my tests show I am D deficitiant?
