Revolutionary insights: Autoimmune thyroid disease with Lisa Costa-Bir and Rachel Arthur
from FX Medicine Podcast Central
In this episode , Lisa Costa-Bir is joined by leading naturopath, registered nutritionist and educator Rachel Arthur to unpack the complex landscape of autoimmune thyroid disease (AITD). Framing conditions like Hashimoto’s and Graves’ as systemic immune disorders - not just thyroid dysfunction - Rachel shares powerful clinical insights on diagnosis, treatment, and long-term management. With her trademark clarity and “catch cries” like “kill and spill,” Rachel breaks down the clinical significance of thyroid antibodies Thyroid Peroxidase Antibodies (TPO) and Thyroglobulin Antibodies (TgAb), Thyroid Stimulating Hormone (TSH) as a “whip,” and the self-perpetuating nature of glandular damage. She also dives deep into evidence for antioxidants like glutathione, selenium and, CoQ10, as well as discussing the value of myo-inositol, magnesium, and vitamin D - and whether there is a role for iodine supplementation in AITD. This episode is a must-listen in integrative naturopathic care for AITD - balancing nutrient timing and dose with lifestyle and dietary interventions. Essential listening for practitioners managing immune-thyroid cases in clinic.
