Bottom Line: The U.S. Preventive Services Task Force (USPSTF) concludes that the current evidence is insufficient to make a recommendation about screening for vitamin D deficiency in asymptomatic adults. Vitamin D performs an important role in bone metabolism. Requirements may vary by individual and no one blood vitamin D level defines deficiency. The USPSTF routinely makes recommendations about the effectiveness of preventive care services and this recommendation updates and is consistent with its 2014 statement.
