Adrian Gombart, a vitamin D researcher at Oregon State University, said the new recommendations are safe and conservative but that 400 units "is probably not enough."
Gombart's lab work in human tissue has shown that vitamin D helps increase levels of a protein that kills bacteria. He said many experts believe that between 800 and 1,000 units daily would be more effective at helping fight disease.
I know so many of us with Lyme (and Bartonella) are deficient in vitamin D...perhaps supplementing in higher doses is helpful?

I'm taking a total of 2400 units/day of Vit D. I recently started seeing an endocrinologist who specializes in osteoporosis and he said that while my reported vit D serum level was high, there's a conversion that has to be made to get an accurate reading on the true vit D level, and that when he did that with my test result, my vit D level was really good.
I'm sorry I can't explain what the conversion is all about. I didn't take the time to have him explain it to me in more detail. Maybe one of the other people here knows what I'm talking about and can explain it.
So he told me to keep taking the amount I'm on. Now I wouldn't recommend this to everyone without consulting a Dr, but this seems to be working for me.

I take 5000iu of vit d. Don't know if its helping, because I am doing so many different abx, herbs, and vits at the same time.

The vitamin D we make from sun exposure is cholecalciferol, and it usually is not tested for, in fact, I don't believe there is a test for it.
The liver converts cholecal into 25 hydroxy cholecalciferol, and the kidneys will then, under direction of several other factors, convert 25 hydroxy cholecal into 1,25 di-hydroxy vitamin D.
I can't tell by your post what your endo tested, but the 25 OH-D is the one to go by. The 1,25 should only be tested when there are compelling reasons.
