I'm pretty sure I have adrenal fatigue due to detoxing so hard with Iodine.
Usually when I get really weak and fatigued I take 10mg pregnenolone, 250 mg of glutathione, and rhodiola and holy basil. This does indeed help, although my adrenals are severely weak and I don't feel nowhere near 100 percent even so.
I could up the dosage of each of these, but I am just very conservative at managing risk and am new to taking these supplements. I also learned a lesson taking more Iodine than I should have.
