Course: Are You Consuming Too Much Iodine? Excess Intake & Thyroid Disorders
Thyroid disorders affect over 40 million people in the U.S. alone, and yet the role of iodine—a key nutrient in thyroid hormone production—remains surprisingly under-discussed in both clinical settings and everyday life.
This recorded one-hour webinar brings together clinical insight and lived experience to explore:
- Why both too little and too much iodine can disrupt thyroid function
- The real-world consequences of unrecognized iodine sensitivity
- The limitations of current medical protocols around thyroid disorder treatment
- Practical strategies for dietitians and patients navigating these issues
For Dietitians: A Nuanced Resource to Support Your Clients
If you're a dietitian working with clients who have thyroid conditions—or are struggling with vague symptoms like fatigue, unexplained weight changes, or temperature dysregulation—this conversation may give you new insight into:
- How iodine overconsumption through fortified foods (like eggs or salt) can tip sensitive clients into dysfunction
- When dietary intake should be revisited before escalating to lifelong thyroid medication
- Why patient-led experimentation with iodine reduction or reintroduction may offer diagnostic clues
- How to support clients with neurological comorbidities like CSF leaks or pituitary disruption, who may respond differently to medication or nutrients
Vincci Tsui, RD and certified intuitive eating counselor, shares her perspective on guiding clients toward individualized care while spinal CSF leak advocate Marion Davis unpacks her firsthand experience of navigating hypothyroidism, hyperthyroidism, and iodine sensitivity in the real world.
For Patients: Clarity, Validation, and Tools for Self-Advocacy
Whether you've been recently diagnosed with a thyroid condition or suspect something’s not right, this session explains in accessible terms:
- What thyroid hormones do and how they’re regulated by your pituitary gland
- How too much iodine—especially in fortified or hidden sources—can mimic or trigger thyroid disorders
- What to expect when rebalancing your iodine intake
- Why medication isn’t always the first or only step—and how to advocate for follow-up testing and dietary exploration
Why This Matters
- 12% of Americans will develop a thyroid disorder in their lifetime
- 60% remain undiagnosed, and many struggle to get answers that take both nutrition and comorbidities into account
- Women are 5–8x more likely to develop thyroid disorders—and also more likely to be dismissed or overtreated
- Dietary iodine is rising in fortified products—yet testing is infrequent and guidelines are outdated
Key Takeaways:
Iodine follows a U-shaped curve of benefit: both too little and too much can harm the thyroid
Not everyone responds well to synthetic thyroid medication—especially those with pituitary disruption or chronic illness
Small changes in iodine intake can cause big hormonal shifts in sensitive individuals
Patients need more frequent lab monitoring and support through dietary transitions
Dietitians can play a pivotal role in identifying red flags and helping clients navigate non-linear recovery paths
