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.

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!

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.
