I was at 20 when tested a few weeks ago - OB is STRONGLY against taking vitamin D supplements...and I called another OB for a second opinion and they agreed, NO Vitamin D because it can cross the placenta.
However, my naturopath and my "integrative" MD feel STRONGLY otherwise and that my OB is sorely mistaken. I tend to believe them more and so I am taking it, but not telling my OB which feels awful.
There is no way I can get enough where I live. It's cloudy and too far from the equator. I, too, take the Biotics, white thick drops. The FDA is in the process of re-evaluating the recommended dose, but even now it is soooooo low that I bet they still only up it to something minimal.
My MD requested I take 2,000 to 3,000 IU. Currently there is 1,000 in my prenantal (more than the FDA safety rec already! ha! and yet they aren't afraid of being sued because the research so highly supports the need) And on top of that I take about 3 drops which equals about 1,400 IU.
Of course overdose is bad too. My MD will be testing me again in 3 months and we'll decide then if I should back down to 1,000 to 2,000 or continue with the 3,000. But 20 is way too low. Like you all have found, my doc says MOST people these days are low. Now I want to get my DH tested. Just want us all to enjoy optimal health!
P.S. Firewoman, I was told that 30-40 was optimal too, even 50 she said was good. Also, I was taking a really good cod liver oil until I became confused/concerned about how much vitamin A I was getting in comparison. That's when my ND just said to rely on the Vit D drops instead. But I know the great benefits of CLO...just thought I'd add my input for ya.
