they're talking about glutamine, magnesium, zinc, (and carbs).
glutamine conversion to glutamate is a problem seen in ms patients.
magnesium and zinc are low in ms patients.
magnesium has a lot to do with muscle relaxation. you can get a blood test, normal range is 0.70-1.10 so you'll come back 'normal' but you actually want to be at least 0.90 mmol/L. boost high magnesium foods such as those listed at www.whfoods.com
the other nutrient i was going to mention for pain and which is significant for ms patients is vitamin d3. again if you get tested the docs will tell you you're 'normal' if your level is at least in the 70s (in nmol/L). protection from diseases with immune involvement has a cut-off more like 150 nmol/L. i've seen 100, 125, 130, and 150 suggested as the minimum for protection against ms and various cancers for example. you don't want your level to go above 250 nmol/L that's when it gets into the toxic range.
here's the link to the athlete's nutrition bit above. like athletes, ms patients tend to have lower zinc. again, low within the 'normal' range. that range is usually 10-20 umol/L. healthy controls have levels more like 18 umol/L. ms patients average in the low teens. when you have optimal zinc status your liver can process vitamin d3 from sunlight or supplements far more efficiently. when i went from zinc deficient to zinc replete, my dose-response to vitamin d3 supplements tripled.
and going back to the glutamine and glutamate thing, there are links to zinc there too:
Protective Action of Zinc Against Glutamate Neurotoxicity...
can you elaborate on the tests you've had done? if you have not had tests for vitamin d3, magnesium, and zinc, these are some of the key ones to watch for ms patients and now you have the targets, within the 'normal' range, that match healthy controls, not ms patients.
hope that helps!
