Yes, thanks for that!

I have this information on my D thread in the Vitamin forum.

It just blows my mind that doctors will test for D levels, and then use the poor performing D2 treatment, still!

I guess their teachers at the CMEs they attend for licensure renewal are not keeping up to date at all!

It is the same for B12 testing and treatment too!

D2 +2%
D3 -6%

What about sunlight? I get all my D from sunshine in the summer.
