Even though I eat many of the foods listed, take a multi vitamin and D3, 2000 iu, I was tested low in "D". My Droctor increased my "D" to 4000 iu's a day. I do have RA and stay out of sun, don't want skin cancer just to get vitamin D.
I never take vitamins or supplements before checking with my Doctor.
Sometimes ones body doesn't absorb certain minerals or vitamins as it should. And one doesn't want to have toxic levels by getting too much.
As far as D2 or ,D3, the bodys preferred form of "D" is D3..
