There is no OTC supplement that can lower cortisol. Please save your money.
Under medical supervision, there are now are few drugs out that can treat Cushing's once you are diagnosed, however they have side effects and most can only be used short term. The usual treatment is to find the source and remove it.
The meds are ketoconizole (an anti fungal) which can only be used short term. Then there are a few new meds out, but they tend to raise estrogen so they are better for men or post-menopausal women. I have had some friends on them and so far no one has made it past a few months. But the field is very new.
Cushing's is quite complex - so if you have it, you have to get diagnosed and then treated. One test is not enough to know if you have it.
There is a supplement that reduces 30-70% of cortisol which may or may not help me at night. I guess at some point I will have to have more testing done..
I've read the process to diagnose cushing's and it looks expensive and tedious :(
That is more indicative of Cushing's syndrome.
If you supplement with anything adrenal, you will add more issues, not help them.
The elevation at night will keep you awake.
One set of tests is not enough to really know and you need source tests to know if it is pituitary, adrenal or other (like taking steroids or other tumor)
