43: Hidden "Healthy" Foods That May Be Sabotaging Your Hashimoto’s Healing | Dr. Izabella Wentz Jul 11, 2025

Show notes

In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz explores the surprising foods that may look healthy on the outside — but secretly sabotage thyroid healing for those with Hashimoto’s. From high-iodine “superfoods” to seemingly innocent whey protein and gluten-free treats, she breaks down what makes these foods problematic and what to eat instead.

What you’ll learn in this episode:

The truth about iodine and Hashimoto’s. While iodine is essential for thyroid hormone production, excessive intake — especially from kelp, spirulina, and seaweed snacks — can trigger autoimmune flares. I’ve seen clients go from mildly symptomatic to completely bedridden after unknowingly overdoing iodine!
Which protein powders are the best options for those with Hashimoto’s. Up to 80% of people with Hashimoto’s react to dairy, and whey is a major culprit. If you’ve been loading up on whey smoothies and are still dealing with bloating, skin issues, or joint pain, you may want to reconsider your protein powder.
Even “healthier” grain products can still be harmful. Einkorn, sourdough, and sprouted wheat may be easier to digest for some — but for people with Hashimoto’s, they can still contribute to leaky gut and molecular mimicry. A survey I conducted years ago found that about 88% of my thyroid community feels better going gluten-free.
Why soy can be sneaky and disruptive. Soy products can interfere with thyroid hormone absorption and increase antibodies. Even fermented versions like miso may cause issues in sensitive individuals. For many clients, removing soy dramatically reduces anxiety and brain fog.
Gluten-free junk food is still junk. Yes, it’s free of gluten, but it’s often high in sugar, low in protein, and filled with inflammatory ingredients. Blood sugar imbalances from gluten-free cookies, pizza, and crackers can make thyroid symptoms worse, not better.
Personalization is everything. Just because a food is labeled as a “superfood” doesn’t mean it’s super for your thyroid. From sushi to smoothies, what supports one person’s wellness could hinder someone else’s healing journey. Bioindividuality matters.

Tune in to learn how the “healthy” foods you might be eating could be making your symptoms worse! Plus, you’ll discover plenty of realistic swaps so you can eat to nourish your thyroid, not aggravate it.

42: Against the Grain: Endocrinologist Dr. Brittany Henderson on Hashimoto’s, Root Causes, T3, and NDT Jul 07, 2025

Show notes

In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz interviews Dr. Brittany Henderson, a board-certified endocrinologist and founder of the Charleston Thyroid Center. Dr. Henderson shares her unconventional journey from a standard T4-only treatment approach to a more integrative practice that includes T4/T3 combination therapy, natural desiccated thyroid (NDT) and root cause medicine. Listeners will gain insight into why many thyroid patients continue to suffer despite “normal” lab results, and how looking beyond the TSH can reveal more accurate root causes of persistent symptoms.

Together, Dr. Wentz and Dr. Henderson explore full thyroid panel testing, the impact of gut health on thyroid medication absorption, the autoimmune mechanisms behind Hashimoto’s, and why early intervention can sometimes reverse the need for lifelong medication. This episode is a must-listen for anyone seeking deeper answers in their thyroid healing journey.

What you’ll learn in this episode:

Why a full thyroid panel is essential. Conventional TSH lab tests can miss critical clues. A comprehensive panel — including free T3, reverse T3, thyroid antibodies, and even an ultrasound — paints a more complete picture of thyroid function and autoimmunity, helping identify issues like poor T4-to-T3 conversion or ongoing immune attacks.
How T4/T3 combination therapy and NDT can change lives. For many patients, especially women and those with low muscle mass or inflammation, levothyroxine alone isn’t enough. Using natural desiccated thyroid or adding T3 can dramatically improve symptoms like fatigue, depression, hair loss, and stubborn weight gain.
The truth about “normal” thyroid labs — and why you might still feel awful. Even with labs in the “normal” range, you could still experience classic thyroid symptoms such as anxiety, brain fog, and irregular periods. Dr. Henderson emphasizes aiming for optimal levels — not average levels — and the importance of tailoring labs to how you actually feel.
Why identifying root causes is key to calming the immune system. Hidden triggers like gut infections (e.g., SIBO or H. pylori), mold exposure, nutrient deficiencies (like iron or selenium), or even oral, tooth and vaginal infections can fuel Hashimoto’s. Identifying and addressing these drivers can significantly reduce thyroid antibodies and improve well-being.
Yes, healing is possible — and meds aren’t always forever. Up to 20% of Dr. Henderson’s patients are able to reduce or even stop thyroid medication by identifying root causes early, lowering inflammation, and supporting thyroid regeneration. Especially in children, teens, and postpartum cases, early intervention can lead to full recovery.

40: Sleep Apnea & Hashimoto’s: The Surprising Link & Root Cause Solutions Beyond CPAP | Dr. Dylan Petkus Jun 30, 2025

Show notes

In this episode of The Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz interviews Dr. Dylan Petkus, a sleep apnea researcher, author, and functional health expert, to explore the often-overlooked connection between sleep apnea and thyroid disorders — particularly Hashimoto’s. Although the condition frequently goes undiagnosed, especially in women, sleep apnea is surprisingly common among those with Hashimoto’s. Dr. Petkus shares his personal journey and research-backed insights into natural, non-invasive approaches for overcoming sleep apnea without relying solely on CPAP machines.

Listeners will discover:

More than 50% of people with Hashimoto’s may also have sleep apnea. The more severe the sleep apnea, the more likely you are to have elevated thyroid antibodies.
Women are often misdiagnosed or missed altogether. Sleep problems are frequently chalked up to menopause or stress, not airway dysfunction.
A scalloped tongue could be a red flag. If your tongue presses against your teeth at night, it may indicate airway obstruction and poor nighttime breathing.
Slow, intentional breathing can retrain your system. Just 10 minutes a day of breathwork can start to shift your patterns, improve oxygen flow at night, and improve sleep quality.
Deficiencies in nutrients like thiamine and copper can make things worse. Supporting your mitochondria may be key to restoring energy and reducing inflammation.

Tune in to learn more about how sleep apnea may be holding back your healing — and what you can do about it.

39: Getting to the Root Cause of Insomnia and Sleep Issues | Dr. Damiana Corca Jun 27, 2025

Show notes

In this episode of The Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz interviews sleep expert and functional medicine practitioner Dr. Damiana Corca to explore the often-overlooked connection between sleep disorders and thyroid health. Dr. Corca shares insights from her clinical experience and her new book, The Deep Blue Sleep Book, which offers a practical roadmap to achieving truly restorative sleep.

Listeners will discover the five primary types of insomnia and how they intersect with Hashimoto’s, adrenal dysfunction, hormonal imbalances, and even gut infections. Whether you’re struggling to fall asleep, waking too early, or feeling “wired but tired,” this conversation offers compassionate, root-cause solutions to help you get the rest you need and deserve.

What you’ll learn in this episode:

There are five distinct types of insomnia, and each requires a different healing strategy. Understanding your type is key to finding relief.
Hashimoto’s often overlaps with adrenal dysfunction, which can make it harder to fall asleep or stay asleep — even if you’re utterly exhausted.
Gut infections like H. pylori and Blastocystis hominis can be hidden culprits behind both thyroid flares and sleep disruptions, even without obvious digestive symptoms.
Hormonal imbalances in perimenopause are a major trigger for sleep issues, especially when paired with blood sugar imbalances and chronic stress.
Histamine intolerance is an under-recognized cause of insomnia, especially in people who struggle with nighttime itching, swelling, or racing thoughts.
Sleep quality — not just quantity — is crucial, and Dr. Corca shares what healthy sleep actually looks and feels like, including tips for waking up refreshed.

38: Fatigue, Hashimoto’s & Epstein-Barr Virus: Root Causes and Healing Tools with Dr. Kasey Holland Jun 23, 2025

Show notes

In this episode of the Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz interviews Dr. Kasey Holland, a naturopathic doctor specializing in chronic illness, viral reactivation, and complex fatigue cases. Drawing from her own journey with reactivated Epstein-Barr virus (or EBV, also known as “mono”), Dr. Holland shares what many traditional approaches overlook — especially when it comes to testing, triggers, and why some people never quite bounce back after mono.

Together, Dr. Wentz and Dr. Holland break down the nuances of EBV reactivation and chronic fatigue syndrome, uncovering its links to autoimmune conditions like Hashimoto’s and exploring the lesser-known co-factors like mold exposure, parasites, and adrenal burnout that can block recovery.

What you’ll learn in this episode:

Why crushing fatigue after mono isn’t “all in your head” — and what to do about it. If you’re still wiped out months or even years after having the Epstein-Barr virus (EBV), there’s a reason. Dr. Holland breaks down the science behind viral reactivation — and how it disrupts energy, mood, and immunity long after the initial infection.
The hidden EBV–Hashimoto’s connection doctors often miss. You’ll learn how a virus you got years ago could be fueling thyroid issues today — and what labs to ask for to find out if the virus is reactivated or contained by your immune system.
Why “fighting the virus” won’t fix your fatigue — unless you fix this too. From parasites to mold to nutrient gaps, this episode unpacks the overlooked root causes that weaken your immune system and allow EBV to flare again and again.
The overlooked role of oxidative stress. Oxidative stress occurs when there's an imbalance between free radicals and antioxidants in the body. When this happens, your cells and tissues become more vulnerable to damage — and so does your immune system. When your body’s defenses are down, EBV has an opportunity to thrive. From mold to glyphosate, high oxidative stress also makes it easier for viruses like EBV to “turn back on.”
What actually works for EBV symptoms — and what’s a waste of time. Discover what really moves the needle — including specific herbs, light therapies, IV vitamin C, adrenal support, and more.

Tune in to learn more about Epstein-Barr virus, the root causes of fatigue, and the comprehensive healing strategies that can help you finally feel like yourself again.

36: Thiamine for Thyroid Fatigue, POTS, SIBO, & More: Formulations & Dosages That Work | Elliot Overton Jun 16, 2025

Show notes

In this week’s episode of the Thyroid Pharmacist Healing Podcast, Dr. Izabella Wentz speaks with nutritional therapist Elliot Overton to explore the powerful but often-overlooked role of thiamine (vitamin B1) in thyroid health. They unpack how thiamine impacts energy levels, brain function, gut motility, and even complex conditions like POTS and SIBO. This conversation is packed with actionable information on identifying hidden deficiencies and restoring nutrient balance — especially for those still struggling with symptoms despite making diet and lifestyle changes.

Listeners will also learn why standard testing often misses thiamine issues, what forms of supplementation are most effective, and how certain medications and stressors can deplete this crucial nutrient. Whether you're dealing with fatigue, dizziness, digestive issues, or thyroid dysfunction, this episode offers valuable insights into an often-missed root cause.

What you’ll learn in this episode:

Why thiamine deficiency is more common than you think and how even people eating a “healthy” diet can be functionally deficient due to multiple factors that impair absorption. This deficiency often goes unnoticed, and might be at the root of persistent fatigue or neurological symptoms.
The connection between thiamine and POTS, SIBO, and thyroid dysfunction. Low thiamine levels can impair the autonomic nervous system, gut motility, and energy metabolism — leading to a host of common symptoms that might surprise you!
How stress, antibiotics, and diet can deplete thiamine even if your intake looks sufficient. Thiamine is a delicate nutrient that gets used up rapidly during times of physical or emotional stress.
The forms and dosages of thiamine that work best for specific conditions. Not all thiamine supplements are created equal — some forms are better absorbed or better suited for neurological versus digestive symptoms.
Why standard blood tests often miss thiamine deficiency — and better ways to assess your needs. Routine lab tests may not reflect true tissue levels of thiamine, especially in chronic illness.

Tune in to learn more about how thiamine may be the missing link in your healing journey.

35: Are Your Adrenals Sabotaging Your Thyroid and Driving Your Fatigue? | Dr. Izabella Wentz Jun 13, 2025

Show notes

In this episode of the Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz uncovers a commonly overlooked root cause of lingering symptoms in those with Hashimoto’s and hypothyroidism: adrenal dysfunction. While many people begin thyroid medication expecting full relief, they often find themselves still plagued by fatigue, brain fog, and mood swings. Dr. Wentz explains how the adrenals — our body’s stress glands — play a vital role in energy, mood, and inflammation regulation, and why so many with thyroid issues also struggle with adrenal imbalances.

Listeners will learn how to spot adrenal dysfunction, explore simple at-home and advanced testing options, and discover practical, research-backed strategies for restoring adrenal health. Drawing from her personal experience and clinical insights, Dr. Wentz also shares a sneak peek into her signature protocol that has helped thousands regain their energy and clarity — without extreme measures or complex testing.

What you’ll learn in this episode:

Optimizing thyroid hormones can unmask adrenal dysfunction: The hormones work together in a feedback loop, and some people will initially feel better, then worse after starting thyroid hormones. This is a red flag for adrenal dysfunction.
Adrenal dysfunction is present in >90% of people with thyroid issues: If you're dealing with morning fatigue, cravings, anxiety, brain fog, or feeling wired but tired, your adrenals may be struggling, even if your labs look "normal."
There are easy ways to test your adrenal health. From checking your blood pressure lying down vs. standing, to observing mood swings and irritability, your body offers clues even before formal testing.
You don’t need expensive tests or extreme measures to feel better. Simple shifts like balancing blood sugar, sleeping more, reducing caffeine, and replenishing key nutrients can transform your energy in just a few weeks.
Adaptogens and nutrients can help you feel like yourself again. Dr. Wentz discusses the ABCs of adrenal recovery — Adaptogens, B vitamins (like B1, B5, and P5P), and vitamin C — and how they can help you rebuild your energy.
Dr. Wentz shares her “Adrenal Kickstart” drink. It tastes like an orange creamsicle and helps replenish electrolytes, stabilize blood sugar, and support cortisol balance, especially if you’re running on fumes in the morning.

Tune in to learn more about the critical connection between adrenal function and thyroid health — and how small shifts in your daily routine can unlock big improvements in your energy, mood, and well-being.

34: Getting to the Root Cause of Fatigue: A Functional Medicine Approach with Dr. Alex Carrasco Jun 09, 2025

Show notes

In this episode of The Thyroid Pharmacist Healing Conversations Podcast, Dr. Izabella Wentz interviews Dr. Alex Carrasco, a board-certified physician, bestselling author, and founder of Nourish Medicine. Together, they unpack the many root causes of fatigue that go far beyond thyroid function. Dr. Carrasco shares how nutrient deficiencies, environmental toxins like mold, and even genetic polymorphisms can contribute to chronic exhaustion, especially in women with thyroid conditions.

Listeners will walk away with a better understanding of why fatigue is a multifactorial issue and how to reclaim their energy with actionable strategies that include smarter supplementation, personalized testing, and simple lifestyle upgrades.

Tune in to learn more about how to uncover and address the real causes behind chronic fatigue.

What you’ll learn in this episode:

Why fatigue is rarely caused by just one thing —and how to uncover all the hidden “logs” in your bonfire. Dr. Carrasco shares her metaphor of fatigue as a bonfire fueled by many logs — like nutrient deficiencies, hormone imbalances, chronic infections, and emotional stress — and how removing them one by one can lead to real healing.
The critical nutrient deficiencies that can mimic thyroid issues (it’s not just B12!). Low levels of thiamine, ferritin, vitamin D, and CoQ10 can all contribute to fatigue, brain fog, and other symptoms that are often misattributed to thyroid dysfunction alone.
The sleep mistake almost everyone makes — and how a simple circadian reset can help. Unfiltered morning sunlight and limiting blue light at night can dramatically improve sleep quality and energy levels throughout the day.
The genetic blueprint that could explain your symptoms (plus what foods can help!). Polymorphisms like MTHFR and COMT can impact how your body handles nutrients, stress, and neurotransmitters, and knowing your genetic tendencies can help you eat and supplement smarter.
The overlooked environmental factor that might be hiding in your home, office… or car. Mold exposure can suppress the immune system, drain your energy, and even impact mood and cognition.
