Vitamin D: A Rapid Review There has been no consensus on the optimal level of vitamin D intake to reduce PTH, and this is why many laboratories report the normal range of vitamin D to be so wide (20 to 40 ng/ml, or in some cases, 50 to 100 nmol). However, this is tantamount to saying a normal total cholesterol level is between 100 to 500.

The Real RDA for Vitamin D Is 10 Times Higher Than Currently Recommended Dr. Heaney and colleagues recently challenged the IOM's vitamin D recommendation, stating the RDA underestimates the need by a factor of 10. Most vitamin D experts also agree that a serum level of 20 ng/ml is too low for optimal health, which means the requirement for most people is even higher than that. GrassrootsHealth, for example, believes a vitamin D level of 40 ng/ml is a more appropriate minimum level.

Vitamin D The FNB committee cited research which found that vitamin D intakes of 5,000 IU/day achieved serum 25(OH)D concentrations between 100–150 nmol/L (40–60 ng/mL), but no greater. Applying an uncertainty factor of 20% to this intake value gave a UL of 4,000 IU which the FNB applied to children aged 9 and older, with corresponding lower amounts for younger children.

How to Get Your Vitamin D Within to Healthy Ranges So the first step to ensuring you are receiving all the benefits of vitamin D is to find out what your levels are using a 25(OH)D test, also called 25-hydroxyvitamin D. There are two vitamin D tests -- 1,25(OH)D and 25(OH)D -- but 25(OH)D is the better marker of overall D status. It is this marker that is most strongly associated with overall health, and it is the one you should ask your physician for.

Vitamin D Test | Home Vitamin D Blood Test Vitamin D Testing. The most accurate way to measure how much vitamin D is in your body is the 25-hydroxy vitamin D test or 25(OH)D test. Vitamin D changes into an active form of the vitamin in the kidney and can be measured through a blood test. The normal range is 30.0 to 74.0 nanograms per milliliter (ng/mL). A lower level indicates vitamin D deficiency, which you should discuss with your doctor.

- This test measures the level of vitamin D in the blood. Two forms of vitamin D can be measured in the blood, 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D. The 25-hydroxyvitamin D is the major form found in the blood and is the relatively inactive precursor to the active hormone, 1,25-dihydroxyvitamin D.

- A doctor will likely order a blood test for the serum concentration of 25(OH)D. This is the type of vitamin D that circulates in the blood. It’s considered a good reflection of how much vitamin D you’ve absorbed from sun exposure and taken in from foods. Levels of vitamin D are expressed in nanomoles/liter (nmol/L) or nanograms/milliliter (ng/mL).

What Is the Normal Range for Vitamin D in a Blood Test? According to the Institute of Medicine, the optimum range of 25-hydroxy vitamin D in the blood is 20 to 50 nanograms per milliliter, abbreviated ng/mL. Less than 20 ng/mL is inadequate, but more than 50 ng/mL may also put your health at risk.
