25-hydroxy-vitamin D or 25(OH)D is the circulating form of vitamin D and routinely used to diagnose vitamin D deficiency. The highly respected
Vitamin D Council – a nonprofit educational organization headed by some of the world’s most prominent vitamin D scientists – recommends that 25(OH)D levels be between 50 and 80 ng/mL, year around.
These levels, they say, assure that vitamin D metabolism is normalized – i.e., in line with “natural” levels normally achieved by people who work in the sun.
To help ensure that patients can obtain information about their vitamin D status, the Vitamin D Council recently partnered with a testing laboratory – ZRT Labs – to make vitamin D test kits available to the public at a discount.
