Pleasantly surprised.
Did not expect much from a supplement. Lost my heath care 15 years ago so I dropped my Synthroid in the process. I’m hypo so I just struggle with all the side effects of a slow thyroid. Recently found out that my nerve damage may be tied to low levels. Ugh, one more thing! After using Thyrostim for less than a month, I can say I feel a difference. Those other hypos out that which experience Synthroid is just a band-aid know what I’m talking about. It is hard to justify the price difference between Synthroid and Thyrostim but I’m worth it. My hair is thinning more and photos of me are not as flattering so I’m excited to see the result over next six months or so with the product.

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!!

Just purchased, will report back in a month or so. It appears to be a high quality product.
I have not started using this item yet as I just received it yesterday. However, I believe it is preferable to taking a pharmaceutical so that is why I purchased it.

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 !

Not for me.
I am surprised at all of the positive reviews because I started taking this and I got so so sick and couldn’t eat. I lost a bunch of weight and believe it almost killed me.It took a few months after stopping it to get back to feeling ok.
