i love coffee, drink it all the time - but not for fatigue. but it won't help your body move ATP (aka energy) around.
yes coffee has magnesium (required for ATP transport) in it, but the caffeine makes you pee the mag out again so, on balance, not great for repairing nutritional fatigue.
if mineral levels are optimized (which as we already know, for most ms patients this is not the case, never mind 'normal' not being good enough) coffee should be fine in moderation.
odd sx? no dx? check w/ dietitian
DRI=MINIMUM eg bit.ly/1vgQclQ
99% don't meet these. meds/lifestyle can affect levels
status can be low in ms & other cond'ns
'but my results are normal'. typical panels don't test all
deficits occur in 'normal' range
