There is so much misunderstanding about supplements.

Immune stimulating substances typically are herbal. Things like Echinacea, and astragalus.

The things listed on that list are basically antioxidants, like blueberries, and strawberries etc. These scavenge free radicals in the mitochondria and PREVENT cell damage, which would include myelin.

Vit D is now recommended for MS patients!

I tend to refrain from posting here because MS is so confusing.
Now there are some early reports that MS is not really an immune issue but an inflammatory one. That is even more confusing.

So I recommend people do their homework like Jack has posted and then decide for themselves. One does not need massive doses anyway IMO of most supplements. Except for the Vit D so far. Many of us use various things on PN forum here for nerve pain and damage, with very good success. Enough with success to minimize pain, dependence on drugs, and halting of progression.

One can find pros and cons on the net about most controversial subjects, and when that happens, it is up to the individual to decide what is best for themselves.
