Thyrovanz® 300mg

I've been without a thyroid for over 24 years now. Like others was using the 300 with great success. The new formulation may as well have nothing in it. My recent labs show a tsh of 18! Never have I seen this in labs. I'm always at .01 I have horrible hypo symptoms too where I feel like death. No wonder seeing the 18 and that my free T4 and T3 are well below normal range It's sad as many of us came to rely and trust in this product for our own survival and well being to find it's so weak now and causing many health issues. The company should be standing up for us and helping us

The 300 mg dose is much weaker than it was pre-Covid. For the last 4 years I've made do with multiple 75 mg or 100 mg capsules and got my levels into the normal range. Since switching back to the 300 mg my thyroid levels have crashed and I've needed to have my prescription meds raised twice. I realize that this is not a standardized product, but something is wrong when 3 x 100 mg capsules does not equal 300 mg capsules.

I have been taking Thyrovanz for years - this is not the strength as it should be and I am very disappointed.

I feel I get the best results with taking multiple 75mg capsules. Unfortunately, they cost more.

I've been taking Thyrovanz for several years, but ever since they came out with the bigger milligrams again after the COVID shipping problem, they are NOT the same.
The 300mg are absolutely worthless, I've to go back down to the 100mg and I am not happy about the added expense. I will be looking for a different NDT

The 300 is back! However, I feel it's weaker than it was before it went out of stock and remained so for 3 years. I found an alternative (which costs more unfortunately!) which I compared to the Thyrovanz 300 and the alternative feels stronger. We waited years because Thyroid Supplements did not have access to enough potent thyroid powder to fill the 300mg caps and did not want to put out a less potent product than what it had been. Now that this is back I feel this is less potent than the 2020 version. Can you work on fixing that ?
