Join Dr. Don Colbert, MD, alongside Mary Colbert and Kyle Colbert, in this continuation of our "Know Your Numbers" series. Today on Dr. Colbert’s Divine Health Broadcast, we dive deep into the thyroid—a small but powerful gland that fuels your metabolism and energy. Dr. Colbert explains why hypothyroidism (low thyroid function) is so common, especially among women, and how autoimmune issues like Hashimoto’s thyroiditis are linked to genetics and hormone fluctuations. You’ll also learn how environmental factors—including endocrine-disrupting chemicals (parabens, phthalates, PFAs)—and certain medications can interfere with thyroid health. Discover the early warning signs of low thyroid, from cold hands and chronic fatigue to eyebrow thinning, weight gain, hair changes, and swelling around the eyes. Dr. Colbert highlights the importance of testing the free T3 hormone (not just TSH and T4) to truly understand thyroid function and optimize energy, mood, and metabolism. Finally, the episode introduces Thyroid Zone, a natural supplement designed to support optimal thyroid function by providing iodine, zinc, B12, tyrosine, and adaptogens to help convert T4 into the active T3 hormone. 👉 Support your thyroid health with Thyroid Zone: https://divinehealth.com/thyroid-zone Explore more from Dr. Colbert: https://divinehealth.com/fiber-zone 📌 Don’t forget to like this video, subscribe to our channel, and visit DivineHealth.com for trusted resources on living long and strong!
