How much can vitamin D levels fluctuate?

I don't know, but would expect levels of an oil soluable vitamin like D to be more stable than water soluable vitamins.

What is the testing procedure for vitamin d levels

I actually had a conversation with my dermotolgist on Vit D deficancies - and almost everyone is low on Vit D even with getting alot of sunshine (which of course he does not recommend). He recommends taking a multivitimin with Vit D.

I know they test it via a blood test.

This Vit D thing is a new concern most likely why it was just brought up - you may have always been low and not known about it. Doctors are just recently testing for this as new research has pointed out the importance of Vit D.

I too was recently diagnosed with Vit D deficiency hence my interest in your post. I can't imagine much fluctuations taking place over weeks. I can imagine it takes a long time for anything like that to take place, probably several months. I have to take Vitamin D capsules = 2,000IU daily to bring me back up to what I need each day. I am never out in the morning sun, which is when we get the benefits of the sun, and because I do get out for a few minutes or more of an afternoon I thought I was going okay. Apparently that wasn't the case with me. When we consider how we are advised to cover up, especially down here in Oz, to prevent melanomas and other skin cancers, we have no chance of getting sufficient Vitamin D naturally from the sun. When you were told how low your Vit D measurement was, were you prescribed a replacement supplement? You should have been.

hello everybody,

please may you kindly review my question and help me out with your answers if you can ....

thank you
