Good Morning. Get your vitamin D on
I take 50,000 IUs 7 days a week and 100,000k on Monday, Wednesday and Friday. I'm a DSr with a 100cm common channel and quite a bit of malabsorption. How much and how often do you take your D3?

Vitamin D Test Accuracy Called into Question

Action Points
HOUSTON -- Two widely used tests to determine vitamin D status produced results that exceeded the allowable limits for error in at least 40% of cases, according to a study reported here.
Using liquid chromatography/mass spectrometry (LC/MS) as the standard, variance by the Abbott Architect and Siemens Centaur-2 tests ranged from -60% to +80%. The maximum allowable error for test results is ±25%, Earle Holmes, PhD, said at ENDO 2012.
Errors with both tests tended to be on the side of overestimating the frequency of vitamin D deficiency, he added.
"Inaccurate test results can lead to overdiagnosis and overtreatment, which is both unnecessary and costly," Holmes, of Loyola University in Maywood, Ill., told MedPage Today. "Vitamin D is one of the most commonly requested laboratory tests, and the use is increasing and more conditions are being associated with vitamin D insufficiency."
Recent studies have demonstrated low levels of vitamin D in association with numerous medical conditions, and the number of links continues to grow. Studies reported at ENDO 2012 showed associations between vitamin D insufficiency and type 2 diabetes, depression, and poor response to osteoporosis drugs.
Such studies have fueled an upswing in clinician orders for vitamin D testing, which in turn has led to development of several new immunoassays for measuring 25 hydroxy vitamin D [25(OH)D] in unextracted serum. Holmes and colleagues examined the accuracy of two newer tests already in wide use.
The study involved 163 randomly selected clinical samples submitted for testing from March 2 to March 7, 2011. The samples were obtained from 123 women who had a median age of 54 and 40 men, median age, 59. Holmes said 98 specimens contained only 25(OH)D3, whereas 65 contained 25(OH)D2 and 25(OH)D3.
For each clinical sample, 25(OH)D was measured by LC/MS performed at an outside laboratory. Holmes and colleagues also evaluated each sample with the Architect and Centaur-2 tests, following manufacturer instructions.

I thought after about 3 months I would see if I could get my PCP to check my D level to see how it was doing after cutting back on this.

I need to get new labs. I just changed to 5,000 a day, but I hadn't been as diligent in taking my vits earlier this year - so I need to see where I'm at. Will be interesting.
