Before considering supplementation with vitamin D, it would be wise to have your vitamin D level tested. This is best done from a nutritionally oriented physician. It is very important that they order the correct test.
The advantage of having your medical or chiropractic physician perform the test is that it will usually be covered by your medical insurance.
Don't Be Fooled -- Order the Correct Test
There are two vitamin D tests -- 1,25(OH)D and 25(OH)D.
25(OH)D is the better marker of overall D status. It is this marker that is most strongly associated with overall health.
The correct test is 25(OH)D, also called 25-hydroxyvitamin D

Dr. Michael Hollick is one of the top vitamin D researchers in the world and he has been advocating higher reference ranges, though not as high as the ones suggested here.
