I think your conclusion is right, En Bloc. Physicians rarely go beyond what they learned in med school, many, perhaps most at any rate. I have two in my family, and I make sure they know what I think about that!
More importantly, congratulations on getting those numbers up! I don't doubt that D2 can increase numbers. I know a number of people who have used it to increase their numbers. None of the studies doubt that it can work, just that it works less effectively than D3. What were you doses like again? How many and how much?
I'm not sure what my numbers will be like, since I can't seem to tolerate the high doses I need. If the insomnia continues at this low does, like 1000-2000 IU per day, I may have to try D2, and see what I can do with that. But one step at a time: first I'll retest in a month after this low does of D3, all I can really tolerate, and then if I don't see results, I'll like try oral D2. I don't think I'll do high dose 50 000 IU, as I always like to start off slowly.
Does one have to come off the supplements before testing to not skew the results? MrsD., how does this go with D testing? I recall you saying something about B12 testing along these lines.

I sort of blew him off as exactly what MrsD said (he was just trying to impress me), but when I got to the pharmacy to pick up my Rx of D2 I asked the pharmacist the same question. guess what: I got the SAME answer! He told me almost the same thing (didn't focus on the 'cellular level', but made same reference to the D3 raising levels quick and for short term while D3 is better for long term results.
So my conclusion now must be that this must be what the doctors and others are taught at some point in training. I have read some the articles MrsD posts and this is newer info. I don't think my doctor is intentionally giving me wrong info (this is a doctor I trust emphatically and has always been up front about everything), but more like this is what he truly believes based upon training years ago. He may not have been advised on newer info out there now.
I will add that today I went back to my PCP for continued problems with my URI and he had run some other labs at my last visit that I wasn't aware of. I thought he was doing my Vit D & B12 at my upcoming Feb 17th visit, but he had done them 2 weeks ago with some other labs...and gave me my results today. After 12 weeks of D2, my level has gone from 26 to 58! So apparently the D2 does something good. I have absorption issues and this time I took a long course of Rifaximin for my SIBO before starting the D2 in hopes I would have better absorption...and it worked. I know in many ways I have had improvement in how I feel overall, but it's been overshadowed by the infection for the last 2 months and hard to really see at times. But I must say that this at least shows that D2 does work in some ways. I have NEVER had a level of 58 before...even on D3. I'm sure the treatment for SIBO and improved absorption is key to my new level. So the jury is still out for me now that i have this huge improvement and proof that D2 will increase vitamin D. I will be very interested in seeing what David's numbers come back after use of D3.
I don't know if I would have believed this if I didn't have the results right in front of me. But clearly, D2 works as well...quite well too, for increasing a level from 26 to 58.
