Was said to post Vit D here so here goes..
Today's MS support group meeting, one guy's taking 10,000 i.u./day = level 30
I take 2000i.u./day & my level's holding 90's. Everyone's different, you have to get tested & not go by dose. 8000iu's had me over 120.
I also told all to try 500mcg's B12 cause I heard many say they've been tired lately. The guy taking 10,000iu's of D is starting B12 shots next week.
