    • Life changing!
Size: 60 Count (Pack of 1)
Treating the adrenal glands is so so important. Most people hop on anxiety or depression meds when treating the adrenals and taking magnesium fixes the issue a big percentage of the time! I was struggling with having a short fuse and feel exhausted mentally all the time, energy crash after any caffeine in the afternoon.This has also improved my quality of sleep so much, and helped me be able to detox better naturally. This is for all adult ages. Be sure to take it in the morning with breakfast, I've found if I take it too late in the day it will mess with my circulation rhythm.I will mostly likely be taking this supplement for the rest of my life! ... show more

    • I’ll NEVER, ever, ever…EVER be without it again! NEVAAA!
Size: 60 Count (Pack of 1)
I have had a NUMBER (putting it lightly) of weird symptoms for the last 15+ years. Water retention (like random 8+ lbs overnight after eating something carb heavy or consuming too much salt or simply because stars are aligned just right), low blood pressure, mild to extreme fatigue, mild to extreme brain fog, memory issues, comprehension issues, insomnia, can’t wake up in the morning, struggle to energy all day, only have energy at night when the rest of the world is meeting with the sandman, stomach issues, random & sporadic weight gain, heat intolerance, cold intolerance, excessive night sweats, headaches, earaches, random nausea, hypoglycemia, passing out, dehydration, electrolyte imbalance, extreme anxiety over nothing, shaking, tremors…you get the point. All of it is random and strikes whenever it feels like, goes away when it wants. I’ve been to every specialist, had all kinds of tests, the only things ever found were anemia and consistent low potassium even on prescription potassium. The only specialist I haven’t been to is an endocrinologist, which is probably the ONE I NEED to see. My doctor didn’t think it was necessary. Her basic blood tests apparently don’t give her any reason to refer me 🙄. Apparently my symptoms aren’t reason enough. I’ve tried ALL types of supplements. I’ve been put on a number of prescriptions that either exasperated my symptoms, created new ones or simply didn’t do anything. In October I bought Thorne adrenal cortex, Neem and Rosemary supplements to try and I started feeling better in a couple days. I did not think it was the adrenal cortex helping. I thought maybe something had been wrong with my gut and the Rosemary and Neem had helped. I could not remember ever feeling that healthy …EVER. It was amazing. No swelling, no weird random symptoms with no rhyme or reason, I had plenty of energy, AND I lost 28 pounds in about 6-7 weeks. Yes, 28! TWENTY EIGHT! I’ve always had a hard time losing weight. I went from a size 6 or 8 to a size 0 or 2. Hello new wardrobe! I had to buy all new undergarments, as well. My chest size went from a 36D to a 32B seemingly faster than I could say Victoria’s Secret. I could eat whatever I wanted without paying for it for days with swelling, boating, stomach pain. It was like I could finally digest food correctly, my electrolytes were in check and I was no longer battling dehydration. It was literally like I had been given a brand new, FUNCTIONING version of my sickly body. I stopped taking the adrenal cortex in December. Again, I thought it was the Oregano oil and Neem supplements that I bought for gut health, especially because of the weight loss. Oregano oil supposedly prevents your body from creating new fat cells. In a couple weeks of not taking the adrenal cortex, I started getting random symptoms here in there, and then on January 6th, I tested positive for COVID. Then ALL my symptoms came back. Especially the fatigue and edema. By mid February, I was still not feeling great and couldn’t understand why I wasn’t getting back to that super healthy feeling. I needed to order more oregano oil, so I pulled up past orders in Amazon and saw the Thorns adrenal cortex and instantly, it hit me. THAT IS WHAT MADE ME BETTER! Not the stupid gut cleaning herbs! Adrenal Cortex saved me. When my doctor has been trying to crack my case for 1.5 plus decades, one little supplement took my misery away. I’m going to take a stab in the dark and guess she doesn’t believe in adrenal fatigue. She sure does believe in chronic fatigue. And fibromyalgia. That’s what she diagnosed me with and basically told me I had to live with it. I had always held on to hope that one of the hundreds of vitamins and supplements I’ve purchased over the years would do SOMETHING for me. If you have any suspicions about having adrenal fatigue or insufficiency, give Thorne Adrenal Cortex a try. If you have it, it’ll work! And don’t try any other new supplements at the same time hahaha! ... show more

    • Okay will come back
Size: 60 Count (Pack of 1)
I observed a subtle yet discernible shift in my energy levels, and I intend to extend the trial period to gather more comprehensive data. Notably, I experienced a reduction in fatigue during the period of its use. I have not noticed weight loss, but I know this is not what it's for. I just wanted to put that out there. ... show more

    • Didn’t work for me but I trust Thorne the most!
Size: 60 Count (Pack of 1)
I took this for a while for all the symptoms of underactive adrenals and pervasive cortisol swelling. For me, this didn’t make a difference. Turns out I had a nasty case of menopausal levels of T and E in my 30s (I basically started peri at 33!) In my case, I needed medical intervention. So if you find this supplement doesn’t help, you may have deeper issues going on. Medication with doctor oversight has instead reversed all the problems I came to this supplement for. However, I (and my functional medicine doctor) trust Thorne the most for efficacy and purity. I have huge success with 3 of their other supplements I take daily for years. If you know this supplement is what you need for adrenal support, I would recommend Thorne from Thorne’s own Amazon storefront over any others! ... show more

    • Consult with a medical professional
Size: 60 Count (Pack of 1)
Do not take this unless your doctor recommends it as it does do something to your adrenal glands. I took this thinking I had high cortisol without asking a medical professional. I was only taking 1 in the morning but it managed to flip my sleep schedule completely. I was up all night tired all day. It gave me terrible anxiety in the evenings as well. I've stopped taking them but hope I have not messed up my adrenal glands in any long term way. If suggested by your doctor then they are potent and seem to work if it's something you need. ... show more

    • Reliable Support for Adrenal Health and Stress—A Supplement I Trust!
Size: 60 Count (Pack of 1)
I’ve been using THORNE Adrenal Cortex for a couple of months and have been genuinely impressed with its quality and effectiveness. The capsules are easy to swallow and gentle on my stomach, and I appreciate knowing Thorne’s reputation for clean ingredients and rigorous testing. Functionality-wise, I’ve noticed a more balanced response to daily stress and less fatigue since adding this to my routine—it really feels like it’s supporting my adrenal health and overall well-being. The bottle itself is compact and looks clean and professional on my supplement shelf, and the labeling provides clear information about dosage and usage. For such a high-quality adrenal support supplement, the price is absolutely reasonable. I feel confident and reassured taking Thorne products, and I highly recommend this Adrenal Cortex supplement to anyone seeking gentle yet effective support for stress management and adrenal function. ... show more

I was super skeptical about this especially bc I already am on something else to help manage my emotions. Hubby told me to take it bc it’ll melt off the “stress belly fat”. Sure enough - within a few weeks, I noticed huge difference!
