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!

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!

    Off the Synthroid

    I have have been taking levothyroxine for my thyroid for almost 10 years now. Since the holistic practitioner I was seeing had gotten too expensive, I was out of options for the prescription. I found out about ancestral supplements and after reading all the raving reviews, I had to try. I'm up to 5 caps a day and no synthroid of any kind. I feel great and have no hypothyroid symptoms.

    Love the Grass Fed Beef thyroid

    I have been on Armour thyroid for many years. Recently I stopped taking it because I have also been taking the ancestral grass fed beef thyroid. I got my bloodwork back recently and the doctor said keep taking the beef thyroid supplement and not continue with the armour. It seems to be doing a fine job of feeding my thyroid what it needs.

    Better than I hoped

    I did not want to take Levothyroxine and found this supplement. Of course, I was skeptical, but hopeful. After a year, my lab results showed my thyroid was working like it should without the synthetic Levothyroxine. My doctor was amazed. I am so happy and have more energy than before.

    Its working for me!

    I have Hashimotos disease that is very instable and goes into dangerous levels, up and down, frequently. I currently take levothyroxine and cytomel for this. I've been taking grass fed thyroid 1 pill a day as well. Im almost done with the first bottle (6 months) alongside my other thyroid meds.. I've been working closely with my doctor and getting labs drawn every 2 months since starting the grass fed thyroid.

    Im excited to report that my thyroid numbers are such that doc has lowered my levothyroxine twice! After 2 decades of instability im finally going in a great direction now. I have more labs scheduled for next month and I will discuss decreasing the levothyroxine further and taking 2 grassfed thyroid daily instead of 1 and see what that does.

    I would be so happy to come off all rx thyroid meds eventually, but the reality is my thyroid is descentigrating (atrophy) so that may not be a future for me. But to have less chemical and more natural would be fantastic as I feel much better on the natural grass fed thyroid.

    I recommended this to my friend for her and her husband for their minor thyroid issues. It is so worth a try!

    Amazing Product!

    I have been trying this natural beef thyroid for a month now in placement of my synthetic thyroid medication! I am so happy with it and the test results are showing that it is definitely doing something, although my doctor is advising me to increase my dosage of the Ancestral to increase my thyroid numbers! We're on the right track and I'm already feeling better by taking a natural supplement verses a medication! Thank you so much!!
