Vitamin D: Should We Screen? Should We Treat?
At this year's American Academy of Dermatology meeting, Dr Barbara Gilchrest talked about a preoccupation with vitamin D status. This has led to expensive and often unnecessary vitamin D testing.
A serum 25-hydroxy-vitamin D of 20 ng/mL is usually considered the lowest acceptable level. But at 20 ng/mL, 97.5% of people have adequate vitamin D. And for at least half of the population, a level of 16 ng/mL is adequate.
Guidelines discourage routine testing of healthy adults without risk factors for vitamin D deficiency. Instead, clinicians should encourage patients to choose foods containing or fortified with vitamin D. For adults who can't get enough vitamin D from their diet, supplementation with 600-800 IU daily should be adequate.
