An excellent natural supplement
This item along with another supplement have allowed me to discontinue a pharmaceutical which was causing horrible afíb. With the help of an endocrinologist I was able to wean off the pharmaceutical and control my thyroid issues with natural supplements, incuding Thyrostim. No more afíb!!

It’s basically a multivitamin
I didn’t notice a difference at all. I have another thyroid med I use and it works great. I just wanted to try this because it had great reviews. Going back to my other one. It wasn’t bad, just not for me.

Sluggish thyroid--These moved the needle on my labs
I've been using Thyrostim for many years now. My labs over the years had shown a sluggish thyroid with low levels of TSH, but nothing that concerned the Dr's. I used this supplement and believe it was responsible for bringing my sluggish levels into balance. That said, I have not had a blood test in a few years and I don't know what my TSH levels are currently. When I cycle off of these (usually because I'm trying to save money) I tend to carry an extra 5 lbs of weight. It's totally anecdotal, but I feel that these help me maintain a health metabolism. I have a healthy diet, exercise regularly, and sleep well. So when added to an overall thyroid supporting lifestyle (I do have a lot of stress though--who doesn't?), these seem to move the needle for me.

Less is More! Helped my Thyroid levels go back to normal and optimal!
Less is more ! I started out with one pill a day & then increased to two pills a day, which is recommended. However, I started breaking out into little hives here and there throughout my body. So I backed off and started taking half a pill a day in the morning. That is my sweet Spot half a pill in the morning! My blood work came back terrific! I couldn’t be happier !

It's only half as good as the granules that you can order from real beef
The granules work better
