So your biggest improvements are in your glucose uptake and along with it thyroid seems to be picking up again. No wonder your feeling better, Sugar and thyroid issues are really massive triggers on adrenals. Your adrenals can now begin to recover and probably your potassium and sodium levels will now begin to improve along with thyroid even further. I've always wondered which comes first - adrenal recover first and then the thyroid and hypoglycemia or vice versa. Seems your results might have answered that.
I'm in the same boat - massive triggers are my hypoglycemia and thyroid, once these two triggers calm down i think and hope that my adrenals will pick up and see an improvement in my NA/K ratio.
Just wondering though, your iron levels are not high, is this an issue for you at all? I also have low iron levels on hair test - but not sure how it is interpreted in a hair analysis test results.
