Review: Game Changer for Hashimotos - This stuff is amazing and feels like the missing piece to my thyroid health journey. Diagnosed recently with Hashimotos and after struggling with intense fatigue, I noticed a huge difference in energy within 48 hours of starting this. Will be coupling it with thyroid med going forward and hope to see even more improvement in thryoid related symptoms. But I can't imagine not taking this!
Review: Changed my life - I’m turning 40 and I have been off synthroid medicine (synthetic) for 1 year supplementing with Raw Thyroid pig’s hormones and still felt something was a little off. I added these minerals to my regiments and I feel like my dormant thyroid is now active and working. My body is burning and working, digestion is on track, and I lost 3lbs in 2 weeks combined with diet and exercise. Coming from someone that never looses weight! They are not just an energy booster, they are essential minerals that your thyroid needs. What a game changer for my health! I’m so happy and grateful for this company! I will be getting my labs done next month to see how I’m doing 😁

## Questions & Answers

**Q: thorne: what is the leucine derived from in this product?**
A: Thorne's leucine ingredient is derived from duck feathers (that are gathered off the ground and not taken directly from the ducks).

A: No, this is not a vegan product. Thorne's Magnesium Thyrocsin contains the amino acid, leucine. Their leucine ingredient is derived from duck feathers (that are gathered off the ground and not taken directly from the ducks).

**Q: Why isn’t the  expiration date on the product?**
A: Most Thorne bottles show expiration dates, however, some show a manufacturing date. If the product is showing a manufacturing date, it is good for 2 years from the manufacturing date.  If you are still concerned, please contact us directly and we will be happy to help.

**Q: Is it vegan?**
A: The label does not specify whether or not the product is vegan. It only specifies that it is gluten free. Neither the Leucine nor the silicon dioxide list source, so they may be a result of animal by product.

### ⭐⭐⭐⭐⭐ So many benefits!
*by A***. on January 16, 2026*

This product! Currently, I’m 40 years old. I just had a baby about 2 1/2 years ago. Since the birth, my energy and mental state, depression, weight gain, everything has been an exhausting journey. I started to really deep dive because my sibling and mother was recently diagnosed with Hashimoto’s hypothyroid disorder, and I started looking into symptoms. I haven’t been formally diagnosed but borderline, however I started taking this Thyrocsin by recommendation to see if it helped at all, and to my surprise it has! I’ve been taking it for just shy of a month religiously. Things I’ve noticed is I have very regular bowel movements, which has never happened in the history of my life. I have energy and it’s not cracked out energy but focus, concentration, and doing my daily chores and just regular responsibilities that typically would wear me out to exhaustion, I have energy and can stay awake till 11 PM or later with no problem. Previously I would be able to fall asleep as soon as I sat down. In addition I have lost about 6 pounds. Not sure if it’s due to increased energy levels increased bowel movements or if it just has helped overall with weight, but that’s a plus and I’ll take it! I also have found that my body temperature is more controlled. I’m not constantly freezing throughout the day bundled up in sweatshirts and any amount of layers I can get a hold of when the temperature in my house is 73. An added benefit that I’ve struggled with since my postpartum has been my sex drive. I found that it has increased and it definitely is quite surprising. Especially since I wasn’t taking it for that at all. Overall, I am a loyal customer to Thorne supplements, but this has definitely taken the cake!
