Iodine & Acne - The Myths, the Science, and Why It Deserves a Second Look

In this episode of To The Root, Robyn Spangler takes a deep dive into one of the most controversial—and commonly misunderstood—topics in skin health: iodine and its connection to acne.For decades, iodine has been viewed with suspicion in the acne community, often blamed for breakouts and inflammation. But is the science really that clear-cut? Robyn unpacks the history behind iodine’s bad reputation, including the impact of flawed mid-20th century research and the rise of halogen competitors like bromide and fluoride that may be complicating the picture.Drawing from clinical experience, current physiological understanding, and the limitations of conventional testing, Robyn explains how iodine—when used properly and alongside companion nutrients—can actually play a key role in improving skin, supporting thyroid function, aiding detoxification, and regulating hormones.If you've been told to avoid iodine-rich foods or are curious about how this essential nutrient might be impacting your skin, this episode offers a much-needed, evidence-informed perspective.Curious if iodine is a missing piece in your skin health puzzle?
