How high should my Vitamin D levels be?

The most accurate determination of vitamin D status is the measurement of 25-hydroxyvitamin D, or 25(OH)D, in the blood. A Scientists’ Call to Action has been issued by 48 international vitamin D researchers to alert the public to the importance of having vitamin D serum levels between 40 and 60 nanograms/milliliter (ng/ml) (100-150 nanomoles/liter, nmol/L) to prevent disease. Almost 90% of U.S. adults have vitamin D levels below that range! Use the  D*Calculator to estimate an appropriate amount of vitamin D supplementation.

Vitamin D supplements taken in the same amount can produce hugely different blood levels in different individuals due to a number of dietary, lifestyle, and individual factors. The presence or absence of vitamin D cofactors (such as magnesium or vitamin K), malabsorption issues (such as a food intolerance), the time of day, whether you take your supplement with food, and whether you smoke or take prescription or over-the-counter medications will all influence blood levels in response to supplementation.  It is important to remember that it is the blood level that has been related to specific health outcomes, not simply the intake amount.

The desirable blood range is 40-60 ng/mL (100-150 nmol/L). Testing, and re-testing 3-6 months after making your adjustments, is the only way to find out if you are in the target range for vitamin D.
