Vitamin D and Thyroid Patients, you need to know about Vitamin D

What test do I do?

There are two:

1) The 25-hydroxy (25OHD) vitamin D blood test. The 25-hydroxy represents your body’s primary circulating form of vitamin D and the precursor to the below.
2) 1,25-dihydroxy vitamin D blood test, which is the active form. This is the test which recommendations of where you want to fall are based on. See Janie’s FROM JANIE comment below.

Bottom line, how much Vitamin D should I take with all the different recommendations and opinions?

Many thyroid patients have noted that they need at least 10,000 IU’s to raise their levels because of absorption issues which are rampant for thyroid patients. Some, because of what’s called the VDR genetic mutation have to continue using that much. The latter means the receptors don’t do a good job grabbing the D.

Another source states this: 1,000 iu’s of Vitamin D3 will raise your Vitamin D level by 7 – 10 ng/ml.  So, for example, if you want to raise your Vitamin D level by 20 ng/ml, you should take 2,000 iu’s.

Also note that depending on what measurement your lab uses,  40 – 60 ng/ml is 100 – 150 nmol/L.
