There are various types of enzymes... I personally take digestive enzymes and I read some promising research on their effectiveness on autism, so I think doctors have a lot to learn about them still. For MS, there are some articles on systemic enzymes to prevent systemic inflammation (actually, I need these too!) and proteolytic enzymes. If you also take digestive enzymes on an empty stomach, they help digest undigested protein and other substances in the GI tract/gut.
On a different note, there has been some research on an enzyme that can cause MS - it does something to the brain that triggers autoimmune responses....sorry I don't remember the details but you can look it up. This is not the same form of enzyme as therapeutic enzymes.
Therapeutic enzymes can help with inflammation, which is often associated with autoimmune disorders. If you can find a good integrative doctor in your area, they might be able to guide you to the right combination of enzymes to use. If you begin treating MS as an autoimmune /inflammatiory disorder, that makes it seem more manageable. That was my plan of attack when my doctor was worried I had MS.
How are you coping with it now? Is it bad or does it come and go?
