I’ll NEVER, ever, ever…EVER be without it again! NEVAAA!
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!

Reliable Support for Adrenal Health and Stress—A Supplement I Trust!
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.

It works too good
I work alot in stressful environments I have ADHD, I have sensory issues including light. I have a long history of using caffeine and have a love/hate relationship with it. I thought all my problems including fatigue is gonna go away with just one cup of coffee. I kept it up, for a couple of days, then weeks, then months, all for me to end up overstimulated, tired, and unproductive. I often feel wired but tired after a cup of coffee. I experience brain fog, eye strain, headaches, and neck pain as a result. No wonder my cortisol is messed up. Then I came across this product, and barely did research. I took a gamble by buying it. Then it arrived, I took one capsule when I'm not feeling my best after a cup of coffee, and suddenly my symptoms have washed away. It was almost like magic.

Amazing supplement for high cortisol
I typically don’t write reviews but this supplement is amazing. My cortisol levels are extremely high and somedays I feel like my head is going to explode because of my cortisol spike. I will say that these have helped me tremendously, and I feel like I’m in control of my body better than before. Highly recommend! I take 3 pills daily

TRY THIS!!!
I love this supplement! I cannot do without it! I noticed significant appetite suppression after about 3-5 days and an overall mood improvement. I noticed sleep improvement after about a week. I can definitely tell the difference if I don’t take it for a day or two so I try not to run out. Thorne products are overall amazing! If you are having weight control or sugary cravings TRY THIS!!

Meeting expectations and make me feel calm and relief.
I have been using this supplement for a month and it’s amazing. I bought it because I have always suffered from stomach inflammation, after years with Gastro doctor treatment that haven’t give me relief I started to think that as I have a very stressful life, maybe the cortisol is making all my body, specially my stomach to be inflamed and I have a try to this supplement which is meeting my expectations. Definitely I will continue to take it.
