Great product!

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!

Noticeable difference

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.

No Armour in Spain

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.

Good product at good price.

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.

Bovine Thyroid with Beef Liver.

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.

Was hopeful

I purchased this in hopes that could replace another supplement I used long ago that contained bovine. Sadly, I not experience anything beneficialthat would make me order it again. I will say that they are a reasonably sized and fairly easy to digest. They may work out for someone else. Just not me.
