When I joined this site a few months back, my Vitamin D was pretty seriously deficient (43 nmol (74-198). Thanks to the advice I have received here, it now stands at 110 nmol - Medichecks, today. So that's a bit of a win for both of us, I reckon. (And bugger-all to do with my hopeless quack who is about as much use as a handbrake on a canoe).
Many thanks, you lot!
