Traditionally associated with skeletal disease, including osteoporosis and fractures, low levels of serum 25-hydroxyvitamin D (25[OH]D) more recently have been linked to a wide range of nonskeletal diseases, including some cancers and autoimmune, cardiometabolic, and neurologic diseases.
Medscape: Should everyone aim for a vitamin D level over 30 ng/mL?
Dr. Garland: Yes. No one should run a serum 25(OH)D less than 30 ng/mL. This means that two thirds of the US population needs supplementation. You may have noticed that President Obama was recently tested for his vitamin D, and it was 22.9 ng/mL. His physicians wisely decided to treat him, and he is now taking vitamin D. I salute the President's physicians for their clinical acumen in performing this good and noble deed to ensure the health of President Obama. It makes me burst with pride and admiration when physicians act in this way with their patients.
Medscape: Would you say that everyone should be tested like the President?
Dr. Garland: Yes, in my judgment. And without delay. We should introduce the population to a new Golden Era of Medicine, based on contemporary scientific discoveries of vitamin D's profound health benefits today rather than waiting for yet another minor increment of confirmation.
