What is the Functional Medicine Approach to Hypothyroidism?

Functional medicine offers a cutting-edge approach to managing hypothyroidism by digging deep into the root causes of the disorder rather than just treating symptoms. Functional medicine is all about personalized care, pinpointing what's causing thyroid imbalances—whether it's nutrient deficiencies, gut health issues, hormonal imbalances, or lifestyle factors—and crafting a tailored treatment plan. 

Functional Medicine Approach to Hypothyroidism

Assessment and Testing

Functional medicine utilizes more extensive assessment and testing than conventional healthcare. We evaluate:

  • Medical history
  • Symptoms
  • Lifestyle factors
  • Environmental exposures
  • All thyroid hormones (not just TSH)

Nutrient Deficiencies

Functional medicine emphasizes the importance of adequate nutrient levels for thyroid function. We look for:

  • Iodine
  • Selenium
  • Zinc
  • Vitamin D
  • Vitamin B-complex

Gut Health

There is a recognized connection between gut health and thyroid function. We might recommend:

  • Dietary changes
  • Probiotics
  • Leaky gut evaluation

Stress Management

Chronic stress can impact thyroid function by affecting the hypothalamic-pituitary-adrenal (HPA) axis. We’ll help you with:

  • Mindfulness
  • Relaxation
  • Adequate sleep

Lifestyle Modifications

Lifestyle changes can support thyroid health, improve medication effectiveness, and enhance quality of life. We’ll look at:

  • Diet and nutrition
  • Sleep habits
  • Movement and exercise
  • Manage stress

Monitor and Adjust

Unlike conventional healthcare, functional medicine won’t leave you hanging. We’ll check in and help you adjust your treatment plan until you reach peak health.


Overall, the functional medicine approach to hypothyroidism aims to restore optimal thyroid function by addressing the underlying causes of hormonal imbalances and by promoting overall health and wellness. 

In functional medicine, patients are actively involved in their health journey; they are educated about their condition, empowered to make lifestyle changes, and encouraged to take ownership of their health. Functional medicine emphasizes personalized, integrative care to achieve long-term improvements in thyroid health and overall quality of life.

Can a Functional Medicine Doctor Treat Hypothyroidism?

Absolutely! Functional medicine doctors specialize in treating hypothyroidism by delving into its root causes rather than just managing symptoms. 

To manage your hypothyroidism, a functional medicine doctor will:


Functional medicine doctors strive to restore optimal thyroid function and improve overall health. If you're seeking a holistic approach to managing hypothyroidism, a functional medicine doctor could be your best ally in achieving lasting wellness.

What Is the Best TSH Level for a Functional Medicine Approach?

In functional medicine, the optimal Thyroid Stimulating Hormone (TSH) level is typically between 1.0 and 2.0 mIU/L. This range is narrower than conventional medicine's reference range, which often extends from 0.4 to 4.5 mIU/L. 

Functional medicine practitioners aim for this tighter range to ensure optimal thyroid function, addressing subtle imbalances that the broader conventional ranges might miss. This approach focuses on achieving the best possible thyroid health and overall well-being for the patient. Along with TSH, your functional medicine doctor will test for the following:

  • Free T3 (FT3): For your best health, FT3 levels should be above 3.2 pg/mL
  • Reverse T3 (RT3): The optimal ratio of RT3 to FT3 should be less than 10:1. 
  • Free T4 (FT4): Ideal FT4 levels are those above 1.1 ng/dL.
  • Antibody Test (Thyroid Peroxidase—TPO and Thyroglobulin—TgAb): Ideally, this test would be negative, indicating no antibodies, or levels should be below 4 IU/mL.
