most alternatives docs that I respect and follow believe that saliva tests are only good for Cortisol testing. All other saliva tests are dubious (according to them).
I would recommend getting a third opinion if possible with some additional blood tests to confirm or refute the saliva tests (per the blood test sticky).
your cortisol looks low and indicates a problem.
your FT3 is slightly low as well. nothing huge, but below ideal levels.
what are your body temperatures at waking and at 9am, 1pm, 5pm?
what about D25-OH, ferritin, B12, etc.?
plant-based hormones like what? progesterone? I personally find it hard to believe in homeopathic medicine, and I run as fast as I can from anyone who pushes their own "natural" supplements - or who requires office visits for injections.
Vitamins/Minerals are a good idea in general, but herbal supplements are a crap shoot. you have no way to know how your system will react, and there are too many other variables to deal with already without throwing in yet another uncontrollable element.
