For almost ALL MS folks getting MORE than a sufficient amount of Vit D is a VERY VERY good idea.

Taking between 2,000 and 4,000 IUs of Vitamin D3 (Cholecalciferol) will result in VERY favorable changes in blood chemistry. Actual good changes start at 1,000 IUs.

MS folks are "ABNORMAL" i.e. SICK and EXCESS Vit D3 is for them GOOD.

Think "outside normal" when it comes to MS needs. Vit D3 is the best non-Rx version to take. Getting some blood testing done before and after starting a Vit D3 supplementing program is a good idea but not really an absolute necessity. The upper limit for Vit D3 supplementing is 10,000 IUs.

The calcium issue is more complex and varies by gender, age and many other complex things. In my situation I am concerned about excess calcification in soft tissues.

I will post some abstracts/articles to explain some of my comments.
