Sure, you're probably nuts like the rest of us but not necessarily about this. I've read this time and time again from people who clinically fall within the normal range, not just MS patients. I really don't know much about the differences in tests but an MMA urine test is supposed to be more accurate than blood. I do take a supplement but think I'm going to ask my PCP to humor me and do the MMA if it's covered by my insurance.

There's really some great info. and knowledgeable people on the vitamin board here. I've been impressed and it's another great reason I'm glad I took the plunge and registered here.
