Yep, they're all the same. I happened to be in the UK a couple of weeks ago. While I was there I had a saliva test for cortisol. 3 of the results were below range; one, just struggled into the very bottom. Ha! I thought, I'll take that to my doctor when I get back to France.
'We don't do that here,' he said. 'I'll give you a blood test.'
'But that's not so accurate,' I said.
'French medicine is best,' he said.
Cobblers, I thought.
Anyway, blood test came back. I was within limits. Returned to the Quack - oops! I meant doctor.
'No treatment, I guess,' I said.
'Non.'
'But what about the saliva test?'
'I don't want to see that,' he said, sticking his head up his own bottom. 'I believe you are suffering from hypochondria - have you thought about hypnotherapy?'
'There is nothing wrong with my head,' I said. (Unlike you, I thought.)
'I will prescribe something,' he said.
'Beta blockers?' I said. (Who could have guessed?)
'Oui,' he said, ushering me from his rooms.
So there we are. This one sample, coupled with the experiences of others in this place, proves that doctors the world over need to extract their heads from their bottoms.
Now. Vitamin D. I haven't looked - there may be stuff about this somewhere here, but it is very important (so I read yesterday) that Magnesium is taken with Vit D if there is any suspicion of low levels - of magnesium that is. By all accounts, Vitamin D uses Magnesium in its transport. And it will hoover up any available magnesium, thereby leaving one short, so to speak. Low levels of magnesium are thought to be rife and can contribute to neurological, muscular and cardiovascular problems (palpitations!)
So there we have it - two for the price of one
