L-carnosine is VERY promising for MS treatment. It's been found that carnosine levels are significantly decreased in both animal MS models and humans with MS. [1]

This [2] completed (results pending) small study will try to verify if supplementing with carnosine will help slow down the progress of or even reverse MS.

Unofficially, I've heard it was a great success. But let's wait.

Edit: Just found another completed study [3]
