hey there lyon
well it's so weird isn't it, i mean if you're heat sensitive then maybe australia in the sun isnt the best place for you, but if you want that "vitamin" d3, it should be perfect. and yet there is such a concern with ozone holes down there, i'm suprised they don't have crop dusters sweeping beachgoers with spf45.
in my case yes i felt good in australia but i had previously megadosed vitamin d3 and my serum was up to a *stellar* 150 nmol/l by the time i left canada, so whatever the d3 was going to do for me, it was done or well on its way already.
k that's the short story done, if you want some long story here goes:
while i was in oz, i stopped supplementing everything for a while in order to get some really good unadulterated bloodwork done, and my b12 was at a personal best of 658 (up from a previous <75, from supplementing and dietary changes, not climate of course) but my d3 was down to 112 nmol/l.
at the same time, my serum iron was officially "deficient" and i had to work to build that back up.
i also realised that my serum uric acid was right in the rrms ballpark (194) whereas those pesky "healthy controls" enjoyed levels averaging just over 290. (gout's more in the 360+ arena)
so d3 is only one of multiple factors in my case, and therefore i'm sure if i upped my d3 and ignored b12, iron, uric acid, not to mention any other variables i haven't yet found out about, i'd still be in trouble. but i am pretty darned sure i've seen studies that showed reduced relapse rates in supplemented, post-dx ms patients. all they have to do to go further, is figure out what ELSE is wrong at the same time. it's such a bugger of a learning curve though! (...also as previously mentioned, serum calcitriol - active hormone form of d3 - more than doubles in late pregnancy; it is a coincidence this is a time when female ms sufferers are protected from attacks?)
and just in closing i want to reiterate for the sake of any new readers that i consider ms to be a multifaceted condition with certain facets applying to smaller groups of afflicted individuals within the overall patient group, therefore one solution will never, and doesn't have to, work for all patients, and i don't consider my answers to be necessarily all relevant to everyone else out there!
