Ep117: PEMF Therapy & Red Light Therapy: Benefits, Differences & How They Work With Andy Smith
Thyroid Pharmacist Healing Conversations with Dr. Izabella WentzShow Notes
In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz interviews Andy Smith, PEMF therapy educator and founder of CELLER8. Andy explains how pulsed electromagnetic field (PEMF) therapy and red light therapy interact with the body at the cellular level – and why these technologies may support energy, sleep, recovery, pain management, and overall wellness.
Andy also shares the personal health crisis that introduced him to PEMF therapy nearly 15 years ago. After emergency surgery and months of recurring infection, antibiotics, pain, and declining mental health, he discovered a therapy that he believes helped him regain his health and ultimately inspired a new career. Together, Dr. Wentz and Andy explore the differences between PEMF and red light therapy, how to incorporate these tools into a realistic wellness routine, and what consumers should know before investing in an at-home device.
What you’ll learn in this episode:
How red light therapy may support cellular energy and whole-body healing. Andy explains how red and near-infrared wavelengths interact with the mitochondria and may help the cells produce more ATP – the energy they need to carry out essential functions. He also clarifies why red light and near-infrared light have different applications, from supporting skin health to reaching deeper tissues.
What PEMF therapy is – and how it differs from red light therapy. Andy breaks down how pulsed electromagnetic field therapy uses low-frequency electromagnetic fields to interact with the body. He explains why PEMF can travel through the body differently than light-based therapies and why he views it as a foundational tool for supporting cellular health.
How a frightening health crisis led Andy to discover his purpose. Andy shares how an unexplained infection, emergency surgery, and six months of recurring symptoms left him physically and emotionally depleted at age 25. After trying PEMF therapy during his recovery, his experience inspired him to leave his family business and dedicate his career to making the technology more accessible.
Why PEMF may complement other wellness therapies. Andy discusses why supporting cellular energy and membrane function may help the body make better use of nutrients, supplements, red light therapy, and other modalities. He also shares how PEMF can be paired with practices such as breathwork or incorporated before therapies like hyperbaric oxygen treatment.
How PEMF therapy may support sleep, energy, recovery, and pain management. Andy describes the changes people commonly report when using PEMF devices, including deeper sleep, improved daytime energy, and gradual reductions in discomfort. He also explains why consistent use matters and offers realistic ways to incorporate sessions into an already busy routine.
What to look for when choosing a PEMF or red light therapy device. Andy explains why trendy, inexpensive, or multi-therapy products may not deliver therapeutic output. He shares practical considerations for evaluating PEMF mats, red light panels, and facial masks – including device specialization, coil coverage, light intensity, diode placement, and ease of use.
Tune in to learn more about how PEMF and red light therapy may support cellular energy, recovery, sleep, and overall wellness – plus practical tips for choosing the right device and making these technologies part of your routine.

In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz speaks with Dr. Efrat LaMandre (Dr. E) about medical gaslighting, why it happens, and how patients can change their approach to ensure they get the right care. Dr. E. explains why doctors may seem dismissive if they don’t find anything on lab tests, why patients can unintentionally dismiss their own symptoms, and how to communicate in a way that healthcare providers understand. She also shares practical strategies for self-advocacy and how to find answers when a doctor’s visit doesn’t bring the clarity you’re certain you need.
In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz speaks with Dr. Richard Horowitz, an integrative physician who has spent more than 40 years working with complex chronic illness, including Lyme and tick-borne diseases. His work eventually led him to develop the MSIDS model, or Multiple Systemic Infectious Disease Syndrome, which looks at 16 different factors that may contribute to chronic illness rather than focusing solely on a diagnosis or individual symptoms.
In this episode of the Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz speaks with hormone expert Dr. Jolene Brighten about why ADHD is so often missed in women and how hormonal changes throughout a woman’s life can influence the way ADHD symptoms show up. From puberty and hormonal birth control to postpartum, the menstrual cycle, perimenopause, and postmenopause, they explore why some women may not recognize their neurodivergence until midlife, and why understanding how the brain works can be a powerful first step toward finding the right tools and support.
In this episode of the Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz interviews Dr. Erin Kinney, naturopathic doctor and author of The Cortisol Cure. She offers a fresh perspective on cortisol and its role in energy, stress, and healing. Rather than viewing cortisol as a hormone that is always “bad” and needs to be lowered, Dr. Kinney explains why understanding how the body uses and replenishes cortisol can change the way we approach burnout, chronic stress, and autoimmune health.
In this episode of the Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz interviews Dr. Miles Nichols, DAOM, MSOM, LAc, founder of Medicine With Heart Clinic and the Medicine With Heart Institute. Dr. Miles shares his personal Hashimoto’s healing journey, including his experience with debilitating fatigue and brain fog despite being told that his initial testing looked “normal.” His search for answers ultimately led him to look beyond conventional thyroid markers and uncover several potential root causes contributing to his symptoms.
