I would have thought cost would not be too much of an issue. If it helps and it is natural the it is worth it. I have had a lot of success, I started out taking heaps, but have reduced down to a maintainence dose. It is not costing me any more than it was before. I think you should just ask your doctor if you have any concerns. It is probably better to be safe than sorry. If you want to check out more information on how they work, I found an excellent site http://www.glyconutrientsreference.com. There is a page specifically on MS under medical conditions. Check it out, it provides a lot of useful and easy to understand information.
