Best Thyroid Extract Supplements of 2025

"Since I started using 1 Body Thyroid Support, I've been thrilled with the results. This supplement is different from others I've tried, as it has a unique blend of nutrients focused on thyroid health. After incorporating it into my routine, I've seen a noticeable boost in my energy and overall well-being. I used to battle with fatigue and mood swings, but this product has helped stabilize my energy throughout the day. Additionally, I appreciate the high-quality ingredients, making me confident in what I'm taking. The capsules are easy to swallow, and I've experienced no side effects, which is fantastic. The customer service is also responsive and supportive. I wholeheartedly recommend 1 Body Thyroid Support to anyone seeking a comprehensive supplement!"

"I started taking the Adrenal and Thyroid Support capsules together and noticed a significant change in my sleep and energy levels. For years, I struggled with chronic fatigue and pain from fibromyalgia, but after starting these supplements, I began to sleep better and wake up feeling more refreshed. I also began to lose weight without altering my diet, which is incredible. Stopping the supplements for a month led to a gradual decline in my energy, so I'm back on them, hoping to reprogram my body to function better. I truly believe these products are what I've needed to address my health issues!"

"Even though my thyroid levels were okay, I always felt something was off. After taking this supplement, I noticed my eyebrows are growing back, my hair is falling out less, and I have more energy. I've been working on other aspects of my health, so I'm not sure how much the supplement has contributed to my weight loss, but I'm feeling more balanced overall."

"I cannot stress enough the importance of this supplement in my life. I am a complete beast without them. My family suffered because I had mood swings, irritation, anxiety, memory loss, and fatigue due to perimenopause, but now I'm full of energy and singing all the time. I take three in the morning instead of the recommended two. I'd recommend it to anyone."

"I’m so happy to have an affordable way to keep my thyroid healthy without pharmaceuticals. This supplement has helped me maintain my weight, eliminated weird heart rhythms, and improved my sleep. I’m thrilled that it works and is affordable. I'm an over-the-top happy customer!"

"After trying various products, I noticed that Natures Craft's thyroid supplement provided me with more energy and focus. Others I tried did nothing. Plus, it's a good price too!"

"I found that this really helps me! I need the extra protein, and it makes a big difference for me."

"After using this while waiting for my doctor's appointment, I experienced no adverse effects. My TSH levels remained normal too. Short-term, it worked well for me."

"I've been taking this for about two weeks, and so far, no negative effects. Supplements can take time to show benefits, but I'm hopeful this one will be different."

"I am absolutely delighted with this product. I only wish it had been available sooner. Since I started taking this supplement, I've faced numerous health issues, but now I feel more alert and focused at work, with energy throughout the day—something I haven't experienced in years. I wholeheartedly recommend this product."

"This is honestly the best vitamin I’ve ever taken! It has helped me tremendously. I consider this one of my best purchases in 2024!"

"While I don't doubt the effectiveness of this product, it didn't work well for me. After being diagnosed with hypothyroidism, I took just one capsule and within ten minutes, I was violently vomiting. I later learned that this supplement shouldn't be mixed with my thyroid medication, as there are known reactions. My throat tightened, and I felt unwell for about four hours. Beware!"

"I was curious how this stacks up against NP THYROID, as I feel good on it, but my TSH levels dropped significantly."

"I've been taking two pills daily and I feel better. It's not perfect yet, but I'm hopeful for full results."

"I was new to thyroid supplements and gained 14 pounds while using this. Not a positive outcome for me."

"I trust Thorne for quality products. While it's tough to tell if supplements truly work, I feel these are a beneficial addition to my routine. I take one each night, and they don't disturb my sleep. This timing allows my thyroid medication to absorb better in the morning. My lab results have shown slight improvement, so something is working. I prefer taking just one pill daily instead of two due to the number of pills I already take. It would be great if the full dosage could fit into one capsule."

"After starting this supplement, I no longer experience mood swings. I feel much more stable and have gained incredible energy! My lab numbers have improved, but they weren't within range at half the dose, so I've switched to the full dose. While I'm still facing some weight gain and joint pain, I believe these are separate issues related to breastfeeding."

"I've been using this supplement for years, initially at half the recommended dose as suggested by my healthcare provider. It dramatically improved my lab results. I still require additional thyroid hormone, but this supplement helps reduce the amount needed. The only downside is the pill size; it's quite large and difficult to swallow, often leaving me with a sensation of something stuck in my throat. I wish Thorne would consider reducing both the size and the recommended dosage."

"I consider myself an herbologist and have always been interested in natural remedies. After my hysterectomy in January, I was worried about weight gain. This supplement has helped me shed those pounds and regain my energy. I feel more like myself again after years of fatigue! So far, it's been a miracle for me."

"After struggling with my weight for so long, this supplement has changed my life! I have great energy now and am hitting the gym six days a week. I feel alive and can actually run, which is something I never thought I would do. If you're on the fence, I say try it! You have nothing to lose."

"I've been using Firestorm for almost 15 years. Initially, it was only available through my doctor, but later it was offered online, which I appreciated. It really supports my thyroid function naturally, especially since prescribed medication didn't work for me. I always check in with my physician when adding supplements."

"After a couple of days, I noticed a positive impact. Each day feels a little better, and I plan to continue using it."

"I've taken this a few times with my levothyroxine, and I've noticed I feel better and sleep better while using it. I'm also trying the ADK vitamins, but this product seems to make a noticeable difference. I intend to keep taking it and will report back later."

"I've found this product to be life-changing. Shipping was incredibly fast, and even with normal thyroid levels, I felt an immediate boost in my energy. I've tried other supplements from this brand and have experienced huge benefits. You really have nothing to lose by giving this a shot!"

"For about three years, I've dealt with a malfunctioning thyroid. After trying various supplements, I came across this Thyroid Support Complex. It took a bit of time, but I appreciate the holistic approach and have noticed a decrease in weight gain. Just be cautious with the larger capsules and take them with plenty of water!"

"I've been looking for a clean, nutrient-dense supplement for my thyroid issues. I can definitely tell a difference in my energy levels and mood when I forget to take it. Plus, I've noticed my hair is growing in thicker!"

"I ordered this product out of desperation, hoping to regain my old self. After about four weeks, I've noticed improved energy levels and clearer mornings. I wake up easier and feel more engaged at home."

"I'm stunned by the effectiveness of this Thyroid Support Complex. I've experienced stable energy throughout the day, better sleep, and no weight gain. My hair has also become thicker and my libido has returned."
