Hi, all, Recently took it upon myself to submit saliva tests for DHEA and cortisol. My DHEA was at the low end of normal - around 195 pg/dl. I'm having real trouble defining my cortisol levels, however. The tests revealed that at 8 AM, levels were .66 mcg/dl. At midnight, they were .11 mcg/dl. The lab said it was within the range of "normal," but those seem very low to me. Can anyone comment? I've been under chronic stress for close to a decade now, coupled with sleep dysfunction following a viral infection. I can't tell if my cortisol levels are low or too high. I don't want to supplement with anything if it's the latter. Any input?
