I was prescribed this supplement/ Medication by my Naturopathic M.D., for both terribly low Adrenal function and to help my body deal with stress. This I have noticed for the past 2 months is working at least on the stress. I used to get terribly anxious in the evening, I thought it was due to a reaction my body was having to the going down in Fentanyl, but it appears it was my Adrenal function. I'm not getting that anxious feeling in the evening anymore and in a few months I'll be off Fentanyl for good. Which should help with my Adrenal function. I'm getting a bit more energy back too. And I know that will improve the longer I'm on this and the longer I'm off Fentanyl. This product is not a overnight cure, you just notice after taking it for a while 3-4 weeks that things are not as bad as they were for you and the longer you're on it, you notice that other things are improving for you. Normal Adrenal function for most is 40-60, my function was a 4, so you see I would try anything my M.D. suggested for me. This product came quickly -in 2 days with Prime, packed well for shipping. I'll definitely buy again, and again !
