I did a little more research and found this . . . It has to do with oxidative stress and MS.

"Conclusion
Our results showed that oxidative stress play an important
role in pathogenesis of multiple sclerosis and suggest the importance
of antioxidants use in diet and therapy in MS patients."

It's interesting and if the claims being made by the manufacturers of Protandim are true and if this study is true, then it stands to reason that it would help people with MS.
