Hello Lisa! Got your message and I will be answeriing that separately.  As a matter of fact, a few months ago I read an article on the connection between Vitamin D and MS.  So I started taking 1000 IU twice a day (I always start supplements at low doses).  Girlfriend, I felt the effects the very next day.  Although it does not help the intense pain I am in all the time, my energy and endurance levels shot up dramatically!  I could not believe it.  I will be increasing to 3000 IU a day on 9/1/09.  I just had my comp blood panel done, and my dr was very impressed with my vitamin D.  Although the results showed  23 for Vitamin D, this was compared with the blood panels from last August when it was at 7.  In fact my whole panel showed excellent blood health if you know what I mean.  I highly recommend increasing your Vitamin D, but start low in case you may have a reaction or something and build slowly.  My family noticed the change immediately, and the D was started all on its own, with no other changes in my meds.   I would definitely give it a try!   Love and Light, Jan
