Can Probiotics Improve Thyroid Function?

Still constipated or bloated, even on thyroid meds, and after antimicrobial gut protocols?

Learn how probiotics and fermented foods can support your gut, immune system, and thyroid, whether your test results are "normal" or not.

In this episode, I walk you through why so many women with hypothyroidism and Hashimoto’s still feel bloated, and/or constipated, despite eating well and taking thyroid medication or thyroid supplements (including glandulars), and why the gut–thyroid connection deserves more attention.

I cover:

• The gut–thyroid–brain axis

• What probiotics can (and can’t) do for your thyroid

• How fermented foods help symptoms like constipation and fatigue

• Importance of timing and consistency with meds and probiotics

• Practical steps for choosing the right strains, starting with food

Key Takeaways:

• Probiotics may not affect your thyroid markers, but they can improve digestion, inflammation, mood, and nutrient absorption

• Fermented foods like sauerkraut, kimchi, kefir and kombucha are easy, powerful additions

• Around 70% of your immune system is in your gut, and up to 40% of your inactive T4 is converted to the active T3 hormone there too

• Leave 3–4 hours between thyroid meds and probiotics
