Trusted by Doctors. Backed by Nature.

"I've been a doctor for over 20 years, and I've seen hundreds of patients suffering from obvious thyroid issues who were undiagnosed or improperly treated by their doctor. When someone starts giving their thyroid everything it needs from a desiccated thyroid product, everything just starts to slowly improve. The one I recommend and trust is Grass-Fed Beef Thyroid from Ancestral Supplements."

Why We Add Grass-Fed Beef Liver To Every Capsule

Thyroid hormones can't work without the right nutrients.


That's why every capsule includes 470mg of Grass-Fed Beef Liver - providing:

Vitamin A to activate T3

B12 & Folate for natural energy

Heme Iron to prevent fatigue & brain fog

Choline for liver and cellular health

Without these nutrients, thyroid tissue alone won't deliver the results you're looking for.


Grass Fed Beef Liver fills the nutrient gaps that thyroid-only products can't address.

TESTIMONIALS

Real Transformations from Real Customers

I love this product! I no longer have a thyroid and I prefer natural products. I was taking other supplements for years and they didn't help at all- I have so many side effects while taking them. Since I started taking Beef Thyroid, I’m more energized, my mood is better, my hair isn’t falling out, and I’m not cold. I will continue to take this product:)

This has really helped me with brain fog and energy! I've decided that taking six pills a day works best for me. I take three in the morning and three at night. They help with my mood too! Thank you Ancestral Supplements for making such a wonderful product!

Alica R.

Verified Buyer

Taking this supplement has been such a simple way to see quick improvement in my thyroid function. Before this supplement I was struggling with brittle hair and little to no energy. Within a few weeks of taking one capsule daily I have seen a huge difference in my hair and energy levels!

    I was sceptical.

    I read things about what thyroid medication does to the body. I prefer to do things naturally. So I decided to try Ancestral Beef Thyroid supplements. It took some time before I noticed any changed. But I stayed with it. Now I have more energy. I have less brain fog and I feel like my clothes fit better. I hope to be able to stop the Rx at some point.

    Great product

    I noticed the condition of my scalp. I’m not sure what the issue was but I was going bald in spots. I’m sure because of my age (68) hormones and everything else is going down hill. But I know taking the Grass Fed Beef Thyroid is making a difference in my health. I also noticed less grey hair. I think all of the Ancestral Supplements I take have made a difference in my health.

    Beef Thyroid

    This product has been so easy to take never had any stomach issues. Never had any issues with taking the capsules.

    I was very sluggish and always had afternoon fatigue. Once I started taking the thyroid capsules, I noticed a huge difference, probably about five days in.

    One thing I do really like about ancestral products, is that you can combine them I also take the minerals, and collagen.

    I really like that these or are natural and good quality product products with high potency

    I always have a back up supply of beef thyroid!!

    Life changing!

    I’ve been taking this product since 2022. My thyroid numbers are in healthy range and I have energy. I’ve been able to stop taking thyroid medication because of this product. The natural beef thyroid works without causing me rapid heartbeat and palpitations. I’m very grateful to have found this supplement!
