Vitamin D supplementation and resultant 25-OH-D blood levels

[Guest guest]

I know that several persons on this list are supplementing with Vitamin D and

also measuring their blood levels of 25-hydroxy-Vitamin D.

I took 2,000 IU of Vitamin D3 for about a year, and never achieved

25-hydroxy-Vitamin D blood levels above approximately 30 ng/ml.

My goal was to raise my blood 25-OH-D levels to at least 50 ng/ml.

I finally reached that level, but only after I raised my level of Vit D3

supplementation to 5,000 IU. I just got the blood test results this week, and my

Vit D level was 51 ng/ml.

The lab that did the testing was LabCorp, which uses the Diasorin method. Both

LabCorp and the Diasorin method are known to be quite accurate with respect to

Vitamin D test results.

I find the Vitamin D newsletter, from the Vitamin D Council to be very

informative
