vit-D puzzle?

What are the current thoughts on Vit-D? I just requested a plethera of labs and some have already been processed (just had blood drawn today) What surprises me is my vit-D is low again at 19.3 ng/mL AND I have been taking 5000 IU's of vit-D every day for almost two years! last year my vit-D on this same supplementation was 67 ng/mL and now with no changes in consumption, it has dropped to 19.3 I am very very puzzled. Does anyone have any idea what could cause such a dramatic drop in vit D even while on significant supplementation? Are there any things that I might be doing that can cause vit-D to be reduced? Very very puzzled......

Re: vit-D puzzle?

That is a real puzzle. Maybe there a problem with absorption has occurred. No idea why. Ill research this and see what I find. Perhaps your doctor can prescribe the 50,000 unit Vitamin D gelcap once or twice a week. This might increase the levels significantly. Get the test rechecked. Lab errors do occur. Once, taking a physical for a pharmacist agency I was working for I was diagnosed as Hepatitis B positive. The test was done again and this proved to be untrue.

Re: vit-D puzzle?

I found something intersting. Low calcium intake is one cause of low levels. If the calcium levels fall the body secretes parathyroid hormone and this hormone changes 25-Hydroxy Vitamin D (what is measured) to the more active Vitamin D form calcitriol. The body makes calcitriol from the 25 hydroxy form so the measured Vitamin D levels drop. Maybe you can increase your calcium intake. Also take the Vitamin D with some fatty food ie in the evening before dinner. Too high a blood calcium also drops the 25 Hydroxy Vitamin D levels due to the thyroid release of a hormone called Calcitonin, so it works both ways.

Re: vit-D puzzle?

Great idea! ...but my calcium has stayed steady at about 9.5 or so. No changes there! I'm wondering if the brand of vit d I am taking isn't well absorbed. I did change brands about 6-9 months ago. But if it isn't that, then I am completely stumped!

Re: vit-D puzzle?

As I understand it, VIT D is a fat absorbed vitamin, important to take with largest meal. I use Douglas laboratories brand, LIQUID D and K, LIQUID Vitamin D-3 along with Vitamin K2. Right now, I'm not taking any vitamins or supplements but I've taken them pretty regularly over the past decade.

3. increasing sclerosis & decreasing activity of L1 met “suggests” mild healing. (SUV 9.4 v 12.1 in May ‘13)
4. scattered lung nodules, up to 5mm in size = stable, no increased activity
5. other small scattered sclerotic lesions, one in right iliac and one in thoracic vertebral body similar in appearance to L1 without PET activity and not clearly pathologic

Re: vit-D puzzle?

Did you change brands? Just wondering as my daughter was taking a multi and got blood work that said her potassium was off the charts. They reran and still off the charts. So they said to stop the multi for a week and re did. All was normal. So a brand change could be the culprit. We trust our supplements and vitamins bit who knows.
Kind regards
