Iron is essential for thyroid function, energy production, and overall health—but when it comes to iron, balance matters. Fatigue. Hair loss. Brain fog. Feeling cold. Exercise intolerance. These symptoms are commonly associated with thyroid dysfunction, but they can also occur with iron deficiency—and sometimes the two conditions overlap. That is one reason iron deserves a closer look in anyone experiencing persistent thyroid-related symptoms. But there is another side to the

A New Episode of Thyroid Talk with Dr. Angela Mazza Birth control pills are among the most commonly prescribed medications for women—but can they affect your thyroid? In our latest episode of Thyroid Talk with Dr. Angela Mazza, we take a closer look at the relationship between oral contraceptives, thyroid hormones, and thyroid blood tests—and why this connection may be especially important if you already have a thyroid condition. How Can Birth Control Pills Affect Thyroid Hor

Every July, we recognize Graves' Disease Awareness Month—an opportunity to increase understanding of a condition that affects millions of people worldwide yet is often misunderstood or misdiagnosed. As an endocrinologist, I frequently meet patients who have spent months—or even years—searching for answers before receiving the correct diagnosis. Many have been told their symptoms were due to anxiety, stress, or simply "getting older." While stress can certainly influence how w

Therapeutic peptides have become one of the most talked-about topics in regenerative and precision medicine. From metabolic health and weight management to immune regulation and tissue repair, peptides are attracting growing interest from both patients and healthcare professionals. But what exactly are peptides, and do they have a role in thyroid health? In the latest episode of Thyroid Talk, I sit down with my co-host, Dawn Sheffield, to explore the science behind therapeuti

When patients experience chronic illness, inflammation, significant stress, injury, surgery, or prolonged caloric restriction, thyroid laboratory values can change in ways that resemble hypothyroidism—even when the thyroid gland itself is functioning normally. This phenomenon is known as Non-Thyroidal Illness Syndrome (NTIS), sometimes referred to as "euthyroid sick syndrome." Traditionally, NTIS has been viewed as a temporary adaptation to illness characterized by: Low free

Iodine is one of the most talked about—and misunderstood—nutrients when it comes to thyroid health. In my clinical practice, I see patients on both ends of the spectrum: Some are taking high-dose iodine supplements hoping to “boost” their thyroid Others are avoiding iodine completely, especially if they’ve been diagnosed with Hashimoto’s The problem? Both extremes can create issues. 👉 This article is based on my recently published paper on iodine and thyroid health, where I

Thyroid nodules are incredibly common—especially in women—and for many patients, the experience of being diagnosed can feel both confusing and frustrating. You’re often told one of two things: “Let’s just watch it,” or “We may need to biopsy or remove it.” But what if there’s more to the story? In my recent publication, “Integrative and Natural Approaches to Thyroid Nodule Treatment: Evidence and Emerging Trends,” I explore a broader, more personalized framework for underst

When we think about longevity, we often look for the next breakthrough—cutting-edge therapies, advanced diagnostics, or novel compounds. But sometimes, the most powerful interventions have been with us all along. Olive oil is one of them. Used for thousands of years and central to the Mediterranean diet, extra virgin olive oil (EVOO) continues to stand the test of time—not just culturally, but scientifically. Today, it remains one of the most well-studied nutritional factors

When we think about the thyroid, most people immediately think of metabolism—weight, energy, maybe hair or skin changes. But the truth is, thyroid hormones do far more than regulate how fast or slow your body runs. They play a central role in how we age. In my recent publication in Hormone & Metabolic Research , we explored how thyroid hormones influence key longevity pathways—including mitochondrial function, metabolic flexibility, and cellular resilience. What emerges is a
