Good Morning. Get your vitamin D on
Interesting article posted on an osteoporosis board I belong to: naturalsociety.com/can-blood-tests-detect-cancer-vitamin-d-t ests/
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?

Like you, I couldn't get my levels up pre-op...had to be very aggessive after surgery...but they came up quickly. Now, I will say that for two years before I decided to research WLS, I was taking the prescription and the OIL based versions...Apparently my body only responds to the DRY form, LOL

Vitamin D Test Accuracy Called into Question
By Charles Bankhead, Staff Writer, MedPage Today

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 was taking 5000 IDs 7 days a week. This is the second year my surgeon has suggested I cut back because my levels are high. Last year I they were not that much too high so I continued with the 7 days a week. I'm not sure what the number is this year because I wont get the printout until I go in August. I am out in the sun a lot more now, so I did cut back to 3 times per week beginning this week.
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 was taking 50,000iu a day and have cut back to 5,000 a day. Mine also was quite high when I was taking 5,000 a day (and I remember when my lab said they changed the way D was being calculated). I switched to 50,000iu once a week and found I tended to forget/miss it for some reason or another. I'm better if I take the same thing everyday- thus the 50,000 a day there for awhile. I also found when I wasn't taking Vit D daily, (even when I was taking the 50k once a week) I got sick... first 2 years post-op I took my D faithfully every day and didn't get sick once.
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.

I was low, like 23 before surgery. I started 50,000 a day and then it got high, 128. My last visit, they said no more D3 for 3 months and would retest. After about 2 months, I started doing 50,000 a week. I retest next month.

My vitamin D levels are OK. I don't take specific supplements, but it's in my multivites, my calcium citrate, and also in my Omega 3's. I use the Celebrate supplements, so they are formulated for malabsorption.

I take about 2000 IU a day in other pills... so not on purpose but it's in my multi and my calcium. Then, on Mondays, I take 50,000 IUs. Except if the week before I've been out in the sun a lot. Then I skip it.
Doing that keeps my Vitamin D levels around 80-100.
