A: I would really look at how your symptoms are presenting. So if you've got lots of great energy, if you feel really well throughout the day, your energy is stable throughout the day, and you're sleeping well at night, that's a really good sign that your adrenals are balanced and that they're aligned with the circadian rhythm.
You can also do the adrenal saliva test. Please keep in mind that these things can change day to day. So, if there's one night that you don't get enough sleep, then your adrenals can be impacted the next day. I generally recommend ZRT Lab for adrenal testing.
