Thyroid supplements

Be careful when taking thyroid supplements. There are a lot of different kinds out there all with different ingredients. Sometimes testing should be done before taking supplements to ensure they are needed and the correct dose. 🔹 Vitamin D: Vitamin D should be an optimal level 50 - 70. If vitamin D status is not adequate the thyroid function won't be optimal.

🔹 Selenium: Some studies show selenium can help decrease TPO antibodies in autoimmune thyroiditis. It is also a factor in the conversion of T4 to active T3. 🔹 Zinc: Zinc is also involved in conversion of T4 to T3. It might also reduce the amount of reverse T3. Zinc supplementation should also be monitored because too much zinc can cause a deficiency in copper.

🔹 Iodine: Iodine is needed for thyroid hormone production, however too much is not a good thing either. 150 mcg is the recommended daily amount. We do get iodine in our diet and sometimes thyroid supplements contain much more (which can have an opposite effect and inhibit thyroid synthesis). Know your iodine levels and consumption. (be aware that seaweed/kelp can have very high iodine levels).

🔹 Ashwaganda: Ashwaganda is an amazing adaptogen that have been shown to increase circulating T3 and T4 (in animal studies). This adaptogen is not safe during pregnancy (please, please check your shakes, ect. for herbs while pregnant or if you are sharing these with your children. It makes me crazy!)

🔹 Glandular thyroid products: I would not recommend taking these without testing or without the help of a professional.

🔹 What products are recommended?

I have seen so many benefit from Thyroid Aid to help support the thyroid in times of stress and disease. The ingredients are so helpful to support a healthy thyroid.


What have you tried or been told to try for your thyroid? Did it help?
