Hi Friends,
Your thyroid is the master thermostat of your body—controlling your metabolism, energy, mood, and body temperature.
But what if I told you the real culprit behind sluggish thyroid symptoms might not be your thyroid at all…
…it might be your gut?
Thyroid disease affects 1 in 8 Americans, yet very few doctors look beyond a TSH blood test. Even fewer explore how gut dysfunction may be silently sabotaging your thyroid hormones.
In the short video above, I reveal 4 powerful ways your gut health directly impacts your thyroid—and what you can do about it:
1. Conversion Crisis: T4 to T3
Your thyroid mostly produces T4, the inactive form of thyroid hormone. But for your cells to actually use it, T4 must convert to T3, the active form.
Here’s the shocker: 20% of that conversion happens in your gut—specifically by your gut bacteria.
If you have Dysbiosis, you may not be converting T4 to T3… leaving you with symptoms like fatigue, depression, and brain fog, even if your labs are “normal.”
2. Nutrient Deficiency from Gut Damage
Your thyroid depends on nutrients like iodine, selenium, zinc, and iron—but if your gut is inflamed or infected, you may not be absorbing them properly.
Conditions like Small Intestine Bacterial Overgrowth (SIBO), H. pylori, or parasites can interfere with nutrient absorption and quietly undermine your thyroid.
This is why in addition to healing the gut, I often recommend my Thyroid Support formula—it provides the essential building blocks your thyroid needs to function optimally.
3. Autoimmunity: Leaky Gut can Flare Hashimoto’s
The most common cause of hypothyroidism in the U.S. is an autoimmune condition called Hashimoto’s.
What’s the #1 root cause of Hashimoto’s flares?
You guessed it: Leaky Gut.
When the gut lining is compromised, it can confuse your immune system, raising your TPO antibodies and inflaming your thyroid.
Healing the gut with L-Glutamine and IgG Guard can calm the immune system and help restore balance.
4. Food Sensitivities Fueling Inflammation
Many people with Hashimoto’s have undiagnosed sensitivities to gluten, dairy, and soy.
Eating these foods may trigger ongoing gut inflammation, which then fuels thyroid inflammation—leading to fatigue, joint pain, brain fog, and stubborn weight gain.
When we remove these triggers, it’s amazing how quickly symptoms improve.
💡 If you or someone you love is struggling with low thyroid symptoms, don’t settle for band-aid solutions.
Understanding the gut–thyroid connection could be the missing piece you’ve been looking for.
I invite you to watch these in-depth videos below to take control of your thyroid health:
Making a berry sauce is a great way to get concentrated antioxidants like anthocyanins and vitamin C!
1 bag of organic mixed berries 32 oz (raspberries, blueberries, blackberries, and strawberries)
1/4 cup of maple syrup
1 tablespoon vanilla extract
Pinch of salt
Put all the ingredients in a pot, cover and heat on medium heat.
After 5 minutes, give it a stir.
As the berries start to sizzle and liquify, you can increase the heat to high until it begins to simmer.
Then lower the heat and allow to simmer uncovered so that the sauce can reduce down and thicken (another 10-15 minutes). Use the back of a large spoon to gently smash the berries.
This sauce is amazing on top of yogurt or kefir with some chopped walnuts. My personal favorite is to have it on top of goat kefir, which is a rich source of butyric, caprylic, and medium chain fatty acids and is often better tolerated by those with traditional cow’s milk sensitivity.
This recipe is fun and easy to make, tastes incredible, and does wonders for your gut microbiome!
The connection between your thyroid and your gut is far more powerful than most people realize. This thyroid–gut axis influences everything from hormone conversion to immune balance and nutrient absorption. When the gut is inflamed or imbalanced, the thyroid often suffers—and symptoms like fatigue, weight gain, and brain fog persist despite “normal” labs. By supporting the gut alongside the thyroid, we can restore balance to this critical axis and unlock deeper healing for the entire body.
Here’s to a thriving thyroid and a happy gut,
