My husband wanted to get off the chemical thyroid prescribed by the doctors. We read that natural thyroid makes people lose more weight. He wanted to try it and I found this product. It has been great for him: He has much more energy. Not sure about losing more weight yet, but it hasn't been long, about 6 weeks. Anyway he is very happy because he feels better!
Has worked great for me. I replaced my LevoThroxine re Hypothyroidism with it. Is working great in company with a few diet changes re lactose and reduction of Gluten 👎🏻
This is a great product for a sluggish thyroid, it naturally contains T4 & T3. I was taking synthetic T3 which I ran into problems with. After switching to bovine thyroid I noticed a great improvement in my energy and brain function. At first the dose can feel a little intense, but within a week I was feeling an improvement. I will say this brand is very clean and I love it, although there are stocking issues sometimes. There has been times where it was out of stock for a couple months.
Since Armour Thyroid is unavailable in my area, I decided to try this as it has the highest concentration of beef thyroid that I could find. I'm feeling pretty good on it, will have labs done the end of the month and see how things shake out. So far, so good.
I've been looking for a good thyroid supplement just to see if I feel different while taking it. This one is a good price and I think very high quality. I've taken it 1 month on then tried a different one and back to this one now. I feel like it does make a difference when I take daily and will continue with it.
synthetic thyroid always made me feel like a drone. ingredient pretty good used this as replacement - working for me so far. the other brand also worked so I guess just real thing works for me.
Seems to be doing some good for my thyroid. No strange taste or smell.
Its hard to find thyroid extract grass fed also packaged with liver, very good product
I have no liver taste after swallowing which is good. Beef raised in pasture (grass fed) in New Zealand and this makes for high quality beef liver. One per day with a meal. Easy to swallow. No after taste. My thyroid healthy has benefitted from this supplement. Very high quality liver and thyroid powders make this the best.
Excellent product. I had a complete thyroidectomy in September 2025. I am on low dose prescription of Levothyroxine. Labs were not good, too high. Started taking Bovine thyroid / bovine liver combo, in 3 months labs started to improve. Almost in the normal range. I prefer a natural supplement, do not want to take a higher prescription dose. October 2025 TSH was 35.65, January 2026 TSH 13.85, September 2026 TSH is 5.43. Doctor had told me in January levothyroxine is dosed by body weight, 25mg is not enough. My improved labs is from taking the natural supplement. Highly recommend. Please don’t ever run out.
