Yes, it is confusing, isn't it. But I suppose Dr S must have his reasons for believing what he believes. I don't know anything about nutri-adrenal, but I'm a bit dubious about it. However, lots of people say it helps. I did try nutri-thyroid but that gave me such terrible stomach upsets that I didn't care to try nutri-adrenal. I know it's not the same, but...
My doctor put me on HydroCortison. An awful lot of people don't care for that, including doctors - don't think dr S does, actually. And I've already had one 'discussion' on that subject on here today, so I'm not keen for another one! lol
I would say they are 'that low'. They may be in range but only just. I've just looked out my first cortisol test. It was an eight o'clock blood test because labs here don't do the saliva test. It was 151 with a range of 45 to 227 and the lab marked it low. Don't know if that's any help. Anyway, my doctor put me on 40 mg cortisol and later upped it to 60. It did the trick at the time, along with the DHEA. But the DHEA all turned to testosterone and I developped acne! So I stopped it. Due to all sorts of crap that life throws at you, I sensed my adrenals were fatigued again so I'm back on the 60 - and taking DHEA gently! - and I'm beginning to pick up again. But that's just me. I hesitate to advise other people to follow my route because we're all so different.
