and, i am not sure. my particular case involves 15 yrs of veganism. which involves a number of nutrient problems also often seen in ms.
please read my signature links to learn about nutrition issues in ms. please note that i do not agree with everything in the links. but they are a start.
you might be interested in 'my' 'regimen' thread.
it's an interesting journey. 25(0H)D3, b12, magnesium, and zinc are great tests, for a start. feel free to ask me any other questions
