I was that patient.
Diagnosed with Hashimoto's at 28, labs “in range”, still exhausted. I read every label on the shelf and could not find one I would take. So I wrote the one I wanted, with an endocrinologist, and put every dose on it. Three things I check on any thyroid supplement before I buy it.
- 1No iodine or kelp at the top of the label.
- 2Selenium at a maintenance dose, 100 mcg, not 25 mcg for show and not 200 mcg forever.
- 3Active forms. Methylfolate, not folic acid. Methylcobalamin, not cyanocobalamin.
An endocrinologist reads this label.
Dr. Flaviu Pătrășcanu sees these patients every week. He goes through the label as he would in consultation, and says plainly who should not take this product.

My wife was interested in this thyroid support supplement because it's specifically formulated for women and doesn't contain iodine. That's an important distinction since iodine isn't necessarily beneficial for everyone with thyroid concerns, particularly those with Hashimoto's. … It's an interesting option for women researching iodine-free thyroid supplements, especially those who want to be more selective about the ingredients they're taking.
4 found this helpfulThis thyroid support complex has no added iodine which is often included in other supplements so you can control your daily iodine intake. Also no ashwagandha as some folks can not take it … I have not experienced any adverse affects or stomach issues while taking this supplement. The capsules are an average size and easy ro swallow. There is an odor to this supplements as it has selenium which is known to give off odor. … I am finding this supplement to be effective in my case.
2 found this helpfulSwallowing these unflavored vegan capsules feels remarkably smooth, easy, & gentle on your system right out of the retail packaging. … The true highlight is the complete exclusion of ashwagandha & iodine triggers, helping you maintain a calm nervous system & lift mental fog safely without any jittery afternoon crashes or heart palpitations.
The ingredient profile is well structured, featuring myo‑inositol at 600 mg, selenium, S‑acetyl glutathione, methylfolate, methyl‑B12, magnesium bisglycinate and chelated zinc. … The capsules have no noticeable taste or odor, and they are gentle on the stomach when taken with food. The ingredient choices feel intentional, especially for autoimmune thyroid support, and the inclusion of active methylated B vitamins is a thoughtful touch.
4 found this helpfulIt has several B vitamins, including B6 and B12 at higher levels. It also has magnesium, selenium, and zinc. I also noted that it is a higher zinc content, so I would not take this on an empty stomach. … The capsules are white and easy to swallow. They do not have any aftertaste. … I have been taking this for a few days and I am starting to notice some positive effects.
This supplement is definitely helpful for hashimotos. I've felt more energy in the weeks that I've been taking it, and overall have been noticing my symptoms less. I'd say it's made a substantial difference!
